Europe Must Triple Offshore Wind Growth Rate To Bring Paris Goals Within Reach

If Europe is to fall in line with the Paris Climate Agreement intention of limiting global warming to 1.5°C above pre-industrial levels, the region must significantly increase its rate of growth for offshore wind development, tripling it at the very least.

These are the primary conclusions published by Michiel Müller from leading international energy and climate consultancy, Ecofys, who penned an article for Energy Post last week explaining that “Europe will need a fully decarbonized electricity supply by 2045” and that “Renewables are essential to making this happen,” specifically, Müller argued that “offshore wind from the North Seas region will be pivotal for realising a 100% decarbonised electricity supply in less than 30 years.”

Müller’s argument is based on research done between Ecofys and its parent company, Navigant, which looked at offshore wind generation in the North Sea for the ten countries surrounding the North Sea — France, Belgium, the Netherlands, Luxembourg, Germany, Denmark, Sweden, Norway, Ireland, and the United Kingdom. Specifically, a white paper published in March by Ecofys and Navigant concluded that 15% of the North Sea region’s total electricity demand could be supplied by offshore wind energy by 2030. This integrated ‘North Sea Grid’ is believed to be the only way to achieve the growth necessary to help meet the Paris Climate Agreement targets.

The research from Ecofys and Navigant determined that the total available onshore generation from various renewable energy sources — wind, solar, bio, hydro, and a little bit of nuclear — would only be able to provide up to 55% of the required capacity to meet the Paris Agreement targets. This leaves 45% needed to be covered by offshore wind, which translates into approximately 230 GW (gigawatts) — 180 GW generated in the North Sea, and the remaining 50 GW in other seas such as the Baltic and Irish Seas, as well as the Atlantic Ocean.

There is currently only 13 GW worth of offshore installed in the region, requiring a massive turning of the screws to increase the rate of delivery. Ecofys and Navigant explains that the installation rate would have to triple from the current 3 GW a year to approximately 10 GW a year.

But, as has been pointed out repeatedly this year, this sort of growth cannot be achieved by one nation alone, and requires national collaboration, coordination, and interconnectivity between North Sea nations. Interestingly, a report published in July by the World Energy Council (WEC) Netherlands posited a similar solution, explaining that the North Sea must play a crucial role in the energy transition ahead for northwestern Europe — a transition which could result in between €100 billion and €200 billion in economic value for neighboring regions in the transition away from fossil fuels.

“The opportunities and diversity thereof in the North Sea are huge,” said Jeroen van Hoof, the chair of WEC Netherlands. “The Energy Transformation in the North Sea creates new industries. We can benefit from huge economic advantages by installing large wind farms. Also, a co-ordinated removal and smart re-use of former oil and gas assets can generate new economic activities. The potential is significant.”

The main point from all that has been published this year regarding the North Sea’s potential, however, is the desperate need for cooperation and interconnectivity between the North Sea’s bordering coutnries. As Müller concludes in his Energy Post article, before the demand for interconnection “can be addressed on the technical level, it will be the collaborative connection between the involved countries and public and private stakeholders that counts.”

“Developing a long-term spatial planning strategy and a robust 2045 roadmap for flexibility options will be two of the key steps to meeting the Paris goals. Joint strategic planning will secure operational security during and beyond the energy transition.”

A partnership between the Colorado Energy Office, GRID Alternatives, and the Poudre Valley Rural Electric Association will work to develop the United States’ largest low-income community solar project aimed at lowering the electricity bills of qualifying low-income residents, affordable housing providers, and nonprofit organizations.

Announced last week, the 1.95 MW (megawatt) Coyote Ridge Community Solar Farm will serve as a large demonstration of the role that solar energy can take in reducing electricity bills for low-income earners — deemed as those who must spend 4% or more of their income on utility bills. Coyote Ridge — a project being developed under a partnership of the Colorado Energy Office (CEO), GRID Alternatives (GRID), and Poudre Valley Rural Electric Association (PVREA) — will also seek to demonstrate “complex financial modelling, a mix of low-income and community benefit subscribers, and unique location siting.”

“PVREA’s Coyote Ridge Community Solar Farm is a thoughtful demonstration of tailoring the low-income community solar model to broaden access and subscriber benefits,” explained Kathleen Staks, Executive Director of the Colorado Energy Office. “This project further conveys scalability to meet local community needs, an objective of our statewide initiative. CEO supports the expansion of a co-op’s ability to bring more projects like these online.”

Coyote Ridge is the seventh project to benefit from a $1.2 million grant made by the Colorado Energy Office to GRID Alternatives back in August of 2015 for the express purpose of partnering with utilities to implement low-income community solar projects. Set to be developed south of Larimer County Landfill near Fort Collins, in northern Colorado, Coyote Ridge is part of a larger statewide initiative designed to demonstrate how solar energy can reduce the energy costs for utilities’ highest-need customers.

“The benefits of this project ripple throughout the community,“ said Chuck Watkins, Executive Director of GRID Alternatives Colorado. “Not only are we increasing access to renewables and lowering energy costs for high-burden individuals and community institutions, the project is also providing over a thousand hours of job training in solar installation, preparing people for long-term careers in the field.”

”Poudre Valley Rural Electric Association is pleased to partner with GRID Alternatives and the Colorado Energy Office on a solar project to benefit cooperative members who have desired to participate in solar energy but have been unable,” added PVREA President and CEO Jeff Wadsworth. “The Coyote Ridge Community Solar Farm exhibits the cooperative nature of our local electric co-op — it brings all of our members together by providing an opportunity to participate in the construction and energy output of the solar farm.”

Coming up today, August 15, PVREA and GRID Alternatives are hosting a Coyote Ridge Community Solar Farm Celebration Event at the Larimer County Landfill (which I assume will be more appealing than it sounds). Additionally, the community solar project is welcome to pretty much anyone volunteering to participate in the construction of the Coyote Ridge solar project.

British renewables investor Greencoat UK Wind is set to add 90MW of capacity to its portfolio following a deal to buy two wind farms from JP Morgan Asset Management for a total of £105m.

Greencoat announced yesterday it has struck deals to buy the 60MW North Hoyle offshore wind farm, located off the coast near Liverpool, and the 30MW onshore wind farm Slieve Divena, which is located in Northern Ireland.

Both developments receive subsidy under the Renewables Obligation Certificate scheme.

The addition of the two projects will take Greencoat UK Wind’s net generating capacity to 547MW, with the deal expected to close later this month.

In addition, the firm’s solar investment arm now manages around 180MW of solar capacity, as of March 31 2017.

Last month Greencoat Renewables launched its first share issue, releasing €270m to fund the expansion of its wind portfolio.

Diesel Car Sale Forecasts Tail Off Amid Air Pollution Fears

Diesel car sales are set to see their market share eroded over the next two years as public concern over air pollution continues to mount, the latest industry forecasts suggest.

New car sales increased by 2.3 per cent last year compared to 2015, but are conversely expected to show a year-on-year decline of 3.7 per cent by the end of 2017, according to figures released late last week by the Society of Motor Manufacturers and Traders (SMMT).

Diesels are set to make up 43.2 per cent of annual demand this year, which is down from 47.7 per cent in 2016 and 50.8 per cent in 2012.

Moreover, SMMT expects market penetration of new diesel cars to further slump to 42.4 per cent next year, demonstrating a slowdown in demand as fears grow over air pollution from roadside transport.

Last month the government unveiled the first part of its strategy for tackling levels of air pollution which breach EU legal limits in many areas of the country. The plan focused largely on road transport, with proposals to consult over introducing a scrappage scheme to encourage consumers away from high polluting diesel cars.

The strategy also raises the prospect of charging schemes being introduced in some urban areas for diesel drivers, although the government insisted alternative approaches for curbing pollution would have to be tried first.

The government’s own modelling has suggested charging schemes wouold represent the most effectvie way of reducing air pollution levels. Meanwhile, London is expected to introduce a Toxicity charge for the most polluting diesel vehicles this autumn.

Industry insiders have conceded that the wave of policy measures, coupled with the fallout from the ‘dieselgate’ scandal, has hit demand for new diesels.

Meanwhile, although SMMT does not provide forecast data for new electric and low carbon vehicles at present, contemporary market figures for sales of ultra low emission cars over the past few years show that, although still only representing a small fraction of the market, sales are beginning to surge.

SMMT figures for June showed sales of alternatively fuelled vehicles (AFV) reached a record market share of 4.4 per cent despite a drop in overall car sales, while the market share for diesel cars simultaneously fell to 43.7 per cent. Sales of electric and hybrid cars in particular grew 33.1 per cent in May compared to the same month last year.

The figures come alongside research by car dealing website Auto Trader showing fears over the impact of diesel vehicles on air quality may have stymied interest in purchasing these cars online, with 56 per cent of fuel type searches on the website for diesels in June compared to 71 per cent in November 2016.

The results came alongside a “significant spike” in searches for alternatively fuelled cars after the government announced plans to ban new petrol and diesel cars from 2040 last month, according to Karolina Edwards-Smajda, Auto Trader’s retailer and consumer product director.

“Given the level of coverage it’s not surprising there has been a decline in searches, but despite the ongoing negative rhetoric the impact on diesel has been fairly limited up to this point,” she said.

Elsewhere, figures for new bus and coach registrations released today by SMMT show a decline in sales during the second quarter of 2017, leading the trade body’s chief executive Mike Hawes to urge local authorities and bus companies to turn their attention towards low emission buses as they attempt to improve urban air quality.

“Having experienced a sustained period of significant growth, it’s natural to see the market level out to steadier levels,” Hawes said of the bus and coach market. “However, with buses so prevalent in our towns and cities, encouraging the uptake of the latest low emission Euro VI diesels and hybrids, as well as zero emission electric buses, will be vital to improving local air quality.”

Sofia city is looking for excellent start-ups that can offer solutions for clean air.

Apply until the 15th of September 2017 HERE and get a chance to participate in the Urban Challenges pitch event in Sofia in October 2017, present your solutions to key stakeholders and accelerate your innovation!

The city of Sofia

Bulgaria’s capital is home to ≈1.3 million people and it is the 15th largest city in the EU. At present, both the population and the economy are growing – 40% of the country’s GDP is produced here, while the unemployment rate stands at 2.5%. Over 50% of the inhabitants are in the age group of 20-54 years.

The problem

As in many other cities around the globe, the air over Sofia is polluted with fine particles (Particulate Matter 10). The city is situated in a valley, surrounded by mountains to the north and south, reducing the circulation of air, which leaves the polluted air lingering over the city for prolonged periods of time. During the cold months the issue is at its worst – PM 10 exceeds the recommended concentrations. The main contributing factors to this threatening issue are the domestic use of solid fuels (especially in winter time) as well as the heavy traffic of old private vehicles and lack of wind due to the topograpy of the region.

What has been done so far to solve the problem?

In order to improve the transportation facilities and ease the heavy traffic in the city, Sofia Municipality has been investing heavily in expanding the metro lines and replacing the entire fleet of busses. However, parallel to the increasing disposable income of people, they observe a significant decrease in the use of public transportation in favor of even more cars on the streets. Other measures include forestation, restoration of green spaces and equipping buildings with energy efficiency installations. Additionally, the Municipality commissioned the Bulgarian Academy of Sciences to develop an early warning system for atmospheric conditions favoring air pollution.

Sofia Municipality’s capacity to innovate

In the past 5 years, Sofia Municipality worked to establish Sofia as a leading regional hotspot for innovation. Forbes listed our city as one of the 10 best places from around the world to start a company. In 2015 the first science and technology park in the region opened doors in Sofia. During this process, the Municipality built capacity to cooperate with startups to apply and help scale their solutions.

They are looking for solutions in the following areas:

The two main contributing factors to air pollution in Sofia are the growing number of old private vehicles on the street and the domestic burning of wood and coal.

#1 Transport and mobility

They are looking for ways to motivate behavioral change in people so that they use their cars less often.

#2 Energy use

The central issue to address here is the domestic burning of wood and coal. How can people be encouraged to shift from one energy source to another?

#3 Retrofit solutions

Additionally, they want to explore retrofit solutions for buildings and cars that would help capture some of the pollutants before they are released to the atmosphere.

Who can apply?

The applicants may be startups, spin offs and/or SMEs that offer effective and innovative solutions minimizing air pollution in urban areas. The solutions should fall within the three main areas mentioned: transport and mobility; energy use and retrofit solutions (please see description above). It will be an advantage if the proposed solutions have already been implemented in other cities.

What will happen next:

A panel of expert jury will select promising startups with their innovations, which will be invited to participate in a pitch event in Sofia, Bulgaria. Prior the event a pitch bootcamp will be held in order to prepare the participants for their final presentations.

Sofia city Air Pollution Challenge Pitch Event

The selected start-ups will get the chance to participate in Sofia’s Urban Challenges pitch event which will be held in parallel to the high-level conference on European air quality – SOFAIR, organized by Sofia Municipality. National and EU policy makers, scientists, business companies and NGOs working and having interest in the field of air quality will be present at the conference. The startups will introduce their ideas to key-stakeholders and will be able to discuss future collaboration and opportunities for solution implementation. The local coordinator of the initiative – Cleantech Bulgaria, will provide further mentorship, business development and local ecosystem network services to the winners in the pitch event.

Finals will be held from 12 to 13 October 2017, in Sofia.

Sun Prairie-based power company WPPI Energy says it will purchase all the electricity generated from a proposed Illinois wind farm for the next 22 years.

Chicago-based renewable energy developer Invenergy plans to build the 53-turbine Bishop Hill 3 wind farm, the Wisconsin State Journal reported. It will be able to generate up to 132 megawatts of power in ideal conditions — enough to power as many as 53,000 businesses and homes.

WPPI spokeswoman Anne Rodriguez said the company anticipates the facility would operate at about 50 megawatts on average. Invenergy spokeswoman Mary Ryan said the maximum output will be limited to 119 megawatts because of transmission connection agreements.

“This agreement provides WPPI Energy with a highly cost-effective resource that will more than double the amount of wind energy in our power supply portfolio,” said Mike Peters, WPPI Energy CEO and president.

Ryan said construction on the project is set to begin in the next few months with commercial operations to start by mid-2018. Bishop Hill 3 will be built in northwest Illinois’ Henry County, close to the Bishop Hill 1 and 2 wind farms.

The project’s cost and the financial terms of the WPPI agreement, which runs through mid-2040, weren’t disclosed. WPPI is a nonprofit regional power company serving 51 locally owned electric companies in three states.

Kwara State government is to deploy solar energy systems to villages, small scale businesses and key government establishments to boost electricity supply and enhance economy activities in the state.

Governor Abdulfatah Ahmed, who disclosed this when he received National President, Licensed Electrical Contractors Association of Nigeria, Otunba Dele Akintola, at Government House, Ilorin, weekend, said the move would provide alternative source of energy supply to critical sectors, instead of waiting endlessly for energy supply through the current hydro-thermal energy source.

He said: “Those to benefit from the proposed solar energy systems include water corporation, hospitals, villages, small businesses and isolated critical government areas.

“Energy is the most important ingredient and determinant of economic growth and development of any country in the world.”

The governor also pointed out that Nigeria was lagging behind in its energy supply needed for industrialization, adding that explained the reason was taking the giant stride.

Ahmed noted that already, the first phase of Light up Kwara was ongoing, with streets light across major roads within Ilorin metropolis.

He promised to extend the solar powered streets light to other towns in the second phase of the project.

Speaking earlier, National President, Licensed Electrical Contractors Association of Nigeria, Otunba Dele Akintola, said he was at Government House to acquit the governor with the readiness of some investors to build solar power stations in the state.

He appealed to Governor Ahmed to consider the proposal and provide 250 hectares of land for the project, saying the project would create employment opportunities for teeming youths and boost the state’s economy.

Akintola added that the United Nations was supportive of states or countries investing in the reduction of environmental pollution and appealed to the governor to buy into the proposal.

Norway’s Arctic Oil & Gas Exploration Plans Stand In The Way Of Achieving Paris Climate Goals, Report Argues

Photo-illustration: Pixabay
Photo-illustration: Pixabay

While Norway has something of a reputation internationally as being “progressive” and “green,” the country’s well fed economy and society is largely the result of a highly productive fossil fuel extraction industry.

In other words, the relatively aggressive electric vehicle incentives on offer there are possible mostly because of the wealth provided by the country’s oil industry. The country’s extensive hydroelectric capacity helps as well … as does the lack of a local auto industry with lobbyists to appease.

While the low population figures for the country and the easy access to cheap oceanic shipping don’t allow for the country to be a major contributor to global greenhouse gas emissions, the reality remains that its state-owned oil and gas industries are a major indirect contributor.

To put that another way, while Norway doesn’t emit anything close to the greenhouse gases much larger countries — such as the USA, Germany, China, Russia, etc. — do, it is one of the largest fossil fuel exporters in the world.

This is a reality that its government seems intent on maintaining, going by its oil and gas exploration plans for the Arctic. This seeming disparity between a stated intent to achieve the goals of the Paris Climate Change Agreement and actual actions and plans is the subject of a new report from Oil Change International.

The report argues that the vast quantity of greenhouse gas emissions that would inevitably accompany continued Arctic oil and gas exploration would undermine plans to limit anthropogenic climate warming to under 2° Celsius.

The Guardian provides more: “The research says 12 gigatonnes of carbon could be added by exploration sites in the Barents Sea and elsewhere over the next 50 years, which is 1.5 times more than the Norwegian fields currently being tapped or under construction.

“The report highlights the ‘cognitive dissonance’ between Norway’s progressive domestic measures to comply with the Paris agreement on emissions cuts and its role as Europe’s biggest exporter of fossil fuels. Climate campaigners say this is like trying to put the brakes on climate change at home while stomping your foot on the global gas pedal.

“Norway has proposed a record number of 93 blocks for oil and gas exploration in the Barents Sea this year, according to the report. Instead of adding new fossil fuel fields, it says Norway should reassert its environmental credentials by relying on existing production.”

The report argues that if a country as wealthy as Norway refuses to leave carbon in the ground, then why would poorer nations (which stand to benefit from it even more)? Which is a good question: If even rich countries aren’t willing to back away from the prospect of “easy” money, then why would anyone else?

The Guardian continues: “The government says such accusations are unfair because they run against the convention at international climate talks for the responsibility for emissions to lie with consumers rather than producers. In this regard — of purely domestic carbon use — it is doing better than most nations because it gets 97% of its electricity from renewable sources, has a high carbon tax, is a leader in promotion of electric vehicles, and is pioneering carbon capture and storage at waste plants and cement factories.” That’s a very misleading statement in my opinion. The renewables in question are hydroelectric and have been in use since well before greenhouse gas emissions were even a topic of discussion. In other words, nothing needed to be done to “achieve” that.

“It also notes that oil and gas output is flat, it is unrealistic to assume that all exploration will be successful and the trend for overall production is away from carbon-heavy oil and towards cleaner gas, which is important as a ‘transition fuel’ for countries that are trying to move away from coal. Officials point out that without Norway’s gas the UK would be far further behind in meeting its climate goals.”

As argued by Norway’s deputy minister for petroleum and energy Ingvil Smines Tybring-Gjedde: “We are part of the solution, not the problem. This government is investing more in renewables and energy efficiency than any other. But renewables are not yet at a level where we can switch off oil and gas. We need a bridge.”

The issue with that statement, of course, is that whether we “need a bridge” or not doesn’t matter. If catastrophic climate warming is to be avoided, then much of the world’s remaining fossil fuel reserves will need to stay in the ground. That’s what matters.

Interestingly, a recent survey in Norway found that around 44% of respondents would support a managed decline of oil and gas production. Not a majority of the population, in other words, which isn’t surprising since around 40% of Norway’s export earnings come from its fossil fuel industry.

Palm Oil Free Certification Programme Launches in UK and Australia

Photo-ilustration: Pixabay
Photo-illustration: Pixabay

A major new certification programme has launched with a view to validating consumer goods products that make no use of palm oil.

Unveiled to coincide with this week’s World Orang-utan Day, the new labelling scheme is now in operation in Australia and the UK following approval from the Australian Competition and Consumer Commission (ACCC), IP Australia, and IPO UK. A further 14 nations are said to have applications pending to introduce the label in their markets.

Dubbed the Palm Oil Free Certification Accreditation Programme (POFCAP), the initiative has been set up by a group of women who have years of experience campaigning to address the environmental issues created by palm oil production.

Soaring global demand for palm oil from consumer goods companies has been widely blamed for fuelling deforestation and biodiversity loss in large parts of Asia.

A number of initiatives have been introduced to provide sustainable certified palm oil, but POFCAP said that despite some improvements efforts to tackle palm oil-related deforestation had experiences “a slow and arduous for many complex reasons”.

“After a decade of work, only 17 per cent of all palm oil used can be classed as ‘non-conflict’ however many millions of hectares of rainforest have undoubtedly been saved by their efforts,” the group added.

The group said the new label – which features a young orang-utan called Jabrick who was a victim of deforestation – would assure consumers that products contained no palm oil.

Australia-based eco cleaning products company Clean Conscience has become the first firm to carry the label, and POFCAP said it was working with a host of other companies on certification.

“Members of the POFCAP team have been involved with researching and educating people on Palm Oil production for a long time and have been increasingly inundated with people asking where or how they could buy Palm Oil free products,” said spokesperson Bev Luff. “With no fully certified Palm Oil free Accreditation Program or Trademark in existence globally we decided the only way forward was to create one.”

The group said the certification scheme would be based on extensive research that will explore and trace all potential palm oil and palm oil derivative ingredients of a product back to their source utilising a number of trusted methods until a definitive answer on its origin is found.

“POFCAP does not certify a product solely on a ‘palm oil free’ statement from an ingredient manufacturer as experience and research has shown this method does not always produce correct results,” the group said.

Ratings Agency Says India Needs To Do More To Achieve 175 Gigawatts Renewables Target

Photo-illustration: Pixabay

Delay in payments from utilities, non-compliance with renewable energy procurement targets, and non-availability of transmission infrastructure for power injection are some of the major issues Indian renewable energy developers are facing. These must be addressed on an urgent basis if the Indian government hopes to achieve 175 gigawatts of installed renewable energy capacity by March 2022.

Ratings agency ICRA has released a report stating that while the government’s policies and market conditions are very well suited for rapid growth in the renewable energy sector, several major challenges remain for the project developers.

According to the agency, the sharp fall in solar tariffs is the result of falling module prices, a sharp increase in the number of project developers, and the jump in number of competitive auctions. As we have reported earlier, solar power tariff bids have fallen 73% since the launch of the National Solar Mission in 2010.

The highest tariff some of the earliest projects still receive is Rs 17.91/kWh, while the lowest and most recent auction saw tariff bids of Rs 2.44/kWh.

The Indian government has already increased its procurement target for solar power to 8% by 2022. However, many states are yet to align their own targets with this national target. States where solar installations are high often have transmission constraints forcing them to cut back on solar power procurement. Additionally, many states still prefer thermal power over solar and wind power as tariffs of majority of older renewable energy projects are higher than coal-fired power plants.

ICRA expects that under a conservative scenario the cumulative capacity requirement for solar and wind to meet the renewable purchase obligation will be 65 gigawatts between 2018 and 2022. This results in an installed capacity of 122 gigawatts by March 2022, significantly short of the 175 gigawatts target.

Current installed capacity for wind and solar power is 32 gigawatts and 12.5 gigawatts, respectively. However, given the large number of solar power auctions in the last few months, ICRA expects a higher capacity addition from solar this year compared to wind energy.

Extreme Heatwaves With “Apparent Temperatures” As High As 55° Celsius To Regularly Affect Much Of World (With 4° Celsius Of Warming Over Pre-Industrial Levels)

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

If global temperatures rise 4° Celsius over pre-industrial levels, then extreme heatwaves with “apparent temperatures” peaking at over 55° Celsius will begin to regularly affect many densely populated parts of the world, according to a new study from the European Commission’s Joint Research Centre.

“Apparent temperatures” refers in this case to the Heat Index, which quantifies the combined effect of heat and humidity to provide people with a means of avoiding dangerous conditions.

The new findings are the result of the researchers involved exploring the relationship between humidity levels and heatwave occurrence — with the “novelty” of the new study being that it “looks not only at temperature but also relative humidity to estimate the magnitude and impact of heat waves.”

At temperatures of 55° Celsius or so, it should be realized, much of the activity that takes place in the modern industrial world would simply have to stop. Such heatwaves would be profoundly debilitating.

The press release provides more: “The study analyses changes in yearly probability for a high humidity heatwaves since 1979 under different global warming scenarios. If global temperatures increase up to 2° C above pre-industrial levels the combined effect of heat and humidity (known as apparent temperature or Heat Index) will likely exceed 40° C every year in many parts of Asia, Australia, Northern Africa, South and North America. Europe will be least affected with up to 30% chance of having such strong heat wave annually.

“However, if temperatures rise to 4° C a severe scenario is on the horizon. Scientists predict that a new super-heatwave will appear with apparent temperature peaking at above 55° C — a level critical for human survival. It will affect densely populated areas such as USA’s East coast, coastal China, large parts of India and South America. Under this global warming scenario Europe is likely to suffer annual heatwaves with apparent temperature of above 40° C regularly while some regions of Eastern Europe may be hit by heatwaves of above 55° C.

“… According to the study, the effect of relative humidity on heatwaves’ magnitude and peak might be underestimated in current research. The results of the study support the need for urgent mitigation and adaptation action to address the impacts of heatwaves, and indicate regions where new adaptation measures might be necessary to cope with heat stress.”

All of which costs money. With all of the problems that will be greatly impacting the nations of the world by that time, it seems pretty likely that not too much will be done to limit the impact of such heatwaves on the poorest and most vulnerable portions of populations (which will likely have swelled quite a lot by then).

The new work is detailed in a paper published in the journal Scientific Reports.

Reusable Carbon Nanotube & Quartz Fiber Water Filter Removes 99% Of Heavy Metals

Researchers at Rice University have developed a simple water filtration material so effective that a single gram of it can treat up to 83,000 liters of contaminated water, after which it can be washed with vinegar and reused.

After a trip to India, where he saw the connection between e-waste and groundwater contamination as a high-schooler, and then working with Rice chemist Andrew Barron, Perry Alagappan, now an undergraduate student at Stanford University, developed a potentially lifesaving filter that has been shown to remove up to 99% of the toxic heavy metals in treated water samples, including lead, copper, cadmium, mercury, and nickel.

The filter material is made from carbon nanotubes which are grown in place on a substrate of quartz fibers (“quartz wool”) and are “then chemically epoxidized.” According to lab tests, the resulting SENT (supported-epoxidized carbon nanotube) filters, when scaled up, are able to quickly ( In addition to being effective and reusable, the new filter uses inexpensive raw materials (“a cost under $0.25/g including materials and manufacturing costs”) and relies on a fairly easy and common skill — the making of vinegar — to keep it functional and reusable.

“Every culture on the planet knows how to make vinegar.”

“This would make the biggest social impact on village-scale units that could treat water in remote, developing regions. However, there is also the potential to scale up metal extraction, in particular from mine wastewater.” – Andrew R. Barron, Department of Chemistry, Rice University

For his ongoing research and developments, Alagappan has taken home the top spot in the Environmental Science category of the 2014 Intel International Science and Engineering Fair, and was recognized with the award of the 2015 Stockholm Junior Water Prize.

Here’s Everything Tesla Wants to Accomplish by 2020

Photo: Twitter/ElonMusk

Elon Musk’s plans for the coming decade are nothing short of ambitious. Among other things, Tesla‘s CEO has promised to dramatically increase car production, launch several completely new cars, and conquer self-driving vehicles by 2020. Here’s a closer look at what exactly Musk has promised Tesla will accomplish during the next few years.

COMPLETE ITS GIANT GIGAFACTORY

Musk’s giant battery factory in Nevada is key to Tesla’s future because it is expected to help the company cut the cost of its batteries by as much as 30%.

The Gigafactory, about 5.5 million square feet, would help the company dramatically cut the cost of its batteries once it’s fully operational in 2018 by “using economies of scale, innovative manufacturing, reduction of waste, and the simple optimization of locating most manufacturing process under one roof.”

In fact, Tesla has said it will create more battery cells at the Gigafactory than all of the lithium-ion battery makers combined did in 2013.

BRING THE MODEL 3 INTO PRODUCTION

The batteries created at the Gigafactory would enable Tesla to produce its first mass-market car, the Model 3. It will be about $35,000 and have a range of more than 200 miles per charge. Tesla started production of the Model 3 earlier this month and planned to begin deliveries at a company event on Friday, July 28.

LAUNCH A COMPACT SUV, DUBBED THE MODEL Y, BY THE END OF 2019 OR EARLY 2020

In July 2016, Musk confirmed Tesla planned to bring to market a new compact SUV, dubbed the Model Y. But a timeline for the vehicle wasn’t disclosed until May, when Musk said during the company’s first-quarter earnings call that it would arrive by late 2019 or 2020. He also said the vehicle would be built on a platform separate from the Model 3.

REVEAL AN ELECTRIC SEMITRUCK IN SEPTEMBER

Musk announced in August that the company was working on a Tesla semitruck, in his “Master Plan, Part Deux.” In June, though, Musk said Tesla was working with major trucking companies to design the company’s first all-electric semitruck.

“We are showing off a working prototype at the end of September, but we have shown it to people who buy heavy-duty trucking, and they all love it,” Musk said during Tesla’s annual shareholder meeting. “They just want to know how many can they buy and how soon.”

While we will most likely get a look at the electric semi in a few months, it’s still not clear when the truck would be available.

ELECTRIC PICKUP TRUCK BEFORE THE CLOSE OF 2019.

Musk also said in his “Master Plan, Part Deux” that Tesla would build an electric pickup truck for consumers. Musk said in April that Tesla would reveal its semitruck in September and its consumer pickup truck in 18 months to two years, meaning sometime between October 2018 and April 2019.

INCREASE THE RANGE OF TESLA CARS TO 1,000 KILOMETERS PER CHARGE.

Tesla’s cars already boast the best range on the market, but Musk has said he aims to dramatically increase how far Tesla’s cars travel on a single charge.

“The record right now for the Model S is 800 kilometers (497 miles). That is the furthest that anyone has driven a Model S,” Musk told the Danish news site Borsen in September 2015. “My guess is probably we could break 1,000 kilometers (621 miles) within a year or two. I’d say 2017 for sure.”

Musk added that by 2020 Tesla could most likely make its cars go as far as 745 miles per charge.

While the record for hypermiling in a Tesla is about 560 miles, the official range for Tesla’s Model S P100D is about 315 miles per charge, according to ratings by the Environmental Protection Agency.

MAKE ITS CARS FULLY AUTONOMOUS.

Another bold promise Musk has made for Tesla is that its cars will be autonomous before 2020.

Tesla began rolling out its new Enhanced Autopilot hardware in October. Musk said at the time that the hardware would enable full autonomy once the software was ready.

However, Musk has said it’s unlikely regulators will have laws in place by the time Tesla’s autonomous cars are ready, so drivers may have to wait a little longer before getting to go hands-free.
While the company plans to do a demo drive in a Tesla in self-driving mode from Los Angeles to New York City by the end of this year, Musk said during a TED Talk in April that it would most likely be 2019 before a driver could take a nap behind the wheel of a Tesla.

PRODUCE 500,000 CARS PER YEAR BY 2018.

Tesla made a little more than 50,000 vehicles in 2015, but Musk said in May 2016 that his company planned to produce no fewer than 500,000 by 2018.

To help put this in perspective, Tesla delivered a little more than 76,000 vehicles in 2016.

Tesla has acknowledged this is an aggressive target, but it’s not shying away from the challenge.

“Increasing production fivefold over the next two years will be challenging and will likely require some additional capital, but this is our goal, and we will be working hard to achieve it,” the company said in its 2016 letter to investors.

PRODUCE 1 MILLION CARS BY 2020.

As if producing half a million cars by 2018 were not enough, Musk wants to kick it up a notch and make 1 million cars a year by 2020.

Why? Demand for the Model 3 was greater than expected, forcing Tesla to reassess its goals. The company had about 325,000 reservations for the Model 3 during the first week of taking deposits.

While it’s no doubt an ambitious plan, Musk has said he is confident Tesla can achieve such aggressive growth.

DOUBLE THE NUMBER OF SUPERCHARGERS BY 2018.

With more Tesla vehicles on the road, Musk is also aiming to build out Tesla’s charging infrastructure.

During the Model 3 unveiling in March 2016, Musk said the company planned to expand its Supercharging network. Superchargers are stations that can charge a Tesla enough almost 200 miles of range in just 30 minutes.

Musk said during the Model 3 event that Tesla would double the number of its Superchargers worldwide, from 3,600 to more than 7,000, by 2018.
However, in April, Tesla said that by the end of this year it aimed to have 10,000 Superchargers worldwide, meaning the company is most likely ahead of schedule.

As of July, Tesla had increased the number of Superchargers to just over 6,000.

TURN TESLA INTO AN ENERGY COMPANY.

Musk doesn’t just want Tesla to make electric cars — he also wants the company to produce the energy that powers the cars.

In November, Tesla acquired SolarCity, a solar-power company founded by Musk’s cousin, Lyndon Rive.

Musk has made clear that his long-term vision for Tesla is a full-service sustainable-energy company.

“The opportunity here is to have a highly innovative sustainable-energy company that answers the whole energy question from power generation and storage to transport,” Musk told reporters during a call shortly after the announcement in June 2016.

“We are a sustainable-energy company,” he added. “This is, broadly speaking, right in line with that. In order to solve the sustainable-energy problem you need generation, storage, and electric cars.”
In October, right before shareholders voted on the SolarCity acquisition, Musk revealed the Tesla Solar Roof. It’s composed of solar shingles and is Tesla’s energy-generation solution.

The company began taking orders in May for its Solar Roof, which costs about $21.85 per square foot.

THE COMPANY IS EXPECTED TO DISCLOSE DETAILS ABOUT ITS TESLA NETWORK, A MOBILITY SERVICE, SOMETIME THIS YEAR.

In July 2016, Musk said in his “Master Plan, Part Deux” that Tesla planned to roll out a mobility service.

At the time, Musk said that once Tesla vehicles were fully autonomous, the company would set up a program for owners to make money off their car by letting other people use it.

“You will also be able to add your car to the Tesla shared fleet just by tapping a button on the Tesla phone app and have it generate income for you while you’re at work or on vacation, significantly offsetting and, at times, potentially exceeding the monthly loan or lease cost,” he said.

In October, the company said Tesla owners who wanted to make money from ride-hailing or ride-sharing could do so only on its ride-hailing network and that it would disclose more details about it this year.

2° Celsius Rise In Global Temperature Is Climate Change “Best Case Scenario”

2 degrees Celsius has become the catchphrase that people around the world use when talking about climate change and how much average global temperatures will rise by the end of this century. It was the talisman that empowered the Paris climate accords in December 2015. It’s the amount of heating that many climate scientists say the earth can tolerate without global warming going completely off the rails and over a cliff.

But a new study by researchers at the University of Washington and funded by the National Institute of Health finds that average temperature rise will most likely be 3.2 degrees Celsius by 2100. They say 2°C is the “best case scenario.” In fact, they say there is a 90% chance that global temperatures will increase between 2° and 4.9° Celsius. That upper number is equivalent to just under 9° Fahrenheit.

“Our analysis shows that the goal of 2 degrees is very much a best-case scenario,” says lead author Adrian Raftery, a UW professor of statistics and sociology. “It is achievable, but only with major, sustained effort on all fronts over the next 80 years. Our analysis is compatible with previous estimates, but it finds that the most optimistic projections are unlikely to happen,” Raftery says. “We’re closer to the margin than we think.”

Statistically, the researchers found there is only a 5% chance that Earth will warm 2 degrees or less by the end of this century. The chance that warming will be at or below 1.5 degrees is less than 1%.

The most recent report from the Intergovernmental Panel on Climate Change (IPCC) included future warming rates based on four scenarios for future carbon emissions. The scenarios ranged from “business-as-usual” emissions from growing economies to serious worldwide efforts to transition away from fossil fuels.

“The IPCC was clear that these scenarios were not forecasts,” Raftery said. “The big problem with scenarios is that you don’t know how likely they are, and whether they span the full range of possibilities or are just a few examples. Scientifically, this type of storytelling approach was not fully satisfying.”

Rather than use the IPCC approach, the researchers focused on three factors they believe are more relevant to predicting climate change — total world population, gross domestic product per person, and the amount of carbon emitted for each dollar of economic activity, a factor known as carbon intensity.

Raftery says he and his colleagues expected total global population to correlate strongly with increasing world temperatures but their analysis did not support that theory. That is because most of the population increase will be in Africa, which uses few fossil fuels.

Carbon intensity — the amount of carbon emissions produced for each dollar of economic activity — did correlate strongly with rising temperatures, however. That value has been declining recently due to more efficient appliances and devices that use electricity. How quickly that value drops in future decades will be crucial for determining future warming.

The study finds a wide range of possible values of carbon intensity over future decades, depending on technological progress and countries’ commitments to implementing changes. “Overall, the goals expressed in the Paris Agreement are ambitious but realistic,” Raftery says. “The bad news is they are unlikely to be enough to achieve the target of keeping warming at or below 1.5 degrees.”

India has auctioned the largest capacity of rooftop solar power projects in history and the results are extremely promising and could provide a much-needed boost to the rooftop solar power market.

The Solar Energy Corporation of India (SECI) recently announced that it auctioned just over 503 megawatts of rooftop solar power projects across 35 states and union territories of the country. The auction was the first phase of a 1 gigawatt rooftop solar power program announced by SECI; under the program, rooftop solar power systems will be implemented atop government buildings across the country.

As per the data released by SECI, 50.2 megawatts was auctioned under the CAPEX model in 32 states. Under the model, the project owner and developer will contribute toward the project implementation through a mix of equity and debt funding and electricity will be sold at a tariff specified by the central or state regulators.

Bids under the CAPEX model were in the form of lowest capital cost needed to set up the systems. The maximum bid allowed was Rs 75,000/kW ($1,166/kW). The highest bid was recorded as Rs 65,000/kW ($1,010/kW).

Just over 453 megawatts of capacity was awarded under the RESCO model, where the developers will be required to bear the entire project cost upfront. The electricity will be sold at the tariff quoted by the developer during auction. Once the project breaks even all revenue from the sale of electricity will actually be developer’s profit.

The lowest tariff bid received under the RESCO model was Rs 2.20/kWh (3.4¢/kWh) for 11.2 megawatt of capacity in the Andaman & Nicobar Islands. The highest bid was placed for 9.6 megawatts of capacity in the state of Bihar at a tariff of Rs 4.59/kWh (7.1¢/kWh).

Some of the leading names in the Indian solar power market that participated in the auction include ReNew Solar Power, Mytrah Energy and Azure Power.

Under the both the models, project developers would also receive financial incentives depending on the time taken to commission the projects and their location; incentives will vary from $116/kW to $700/kW.

Increased Hydro & Solar Generation Brings Down Electric Prices In El Salvador

Increased hydro power generation and a newly commissioned solar power project have reduced the overall cost of electricity in El Salvador, the power regulator of the country, Siget, recently stated.

Siget recently announced that the electricity tariff for the period of 15 July to 15 October 2017 has fallen by 3.09% to $118.9/MWh. The price fall has come as a result of increased hydro power generation and the operationalization of a solar power project.

A 60-megawatt solar power project was commissioned by Neoen, a French independent power producer. The project was secured by the company in a competitive auction and sells electricity at a tariff of $0.1019/kWh ,which is 18% lower than the electricity tariff was for the first quarter of this year. The project was secured in a competitive auction held in 2014, and has been commissioned in partnership with a local conglomerate Almaval.

El Salvador has organized several competitive auctions for wind and solar power projects over the last couple of years. Earlier this year, it allocated four solar power projects with 120 megawatts of total capacity at tariffs between 4.955¢/kWh to 6.724¢/kWh. Successful project developers offered 36% to 53% discount compared to the ceiling tariff of 10.53¢/kWh set by the government.

The successful bidders — Tracia Network Corporation, Capella Solar, Sonsonate Energy and Asocio Ecosolar — will sign power purchase agreements of a duration of 20 years and will be required to commission the projects in 2019.

Once these projects are commissioned, the percentage of renewable energy in the country’s electricity mix will increased substantially. And given their low tariffs, the overall electricity price would also fall sharply.
