Cutting the Cost of Ethanol, other Biofuels and Gasoline is Pretty Simple

Biofuels like the ethanol in U.S. gasoline could get cheaper thanks to experts at Rutgers University-New Brunswick and Michigan State University.

They’ve demonstrated how to design and genetically engineer enzyme surfaces so they bind less to corn stalks and other cellulosic biomass, reducing enzyme costs in biofuels production, according to a study published this month on the cover of the journal ACS Sustainable Chemistry & Engineering.

 – The bottom line is we can cut down the cost of converting biomass into biofuels – said Shishir P. S. Chundawat, senior author of the study and an assistant professor in the Department of Chemical and Biochemical Engineering at Rutgers University-New Brunswick.

Typically, the enzymes tapped to help turn switchgrass, corn stover (corn stalks, leaves and other leftovers) and poplar into biofuels amount to about 20 percent of production costs, said Chundawat, whose department is in the School of Engineering. Enzymes cost about 50 cents per gallon of ethanol, so recycling or using fewer enzymes would make biofuels more inexpensive.

In the United States, gasoline typically contains up to 10 percent ethanol and corn grain is the primary feedstock of ethanol, according to the U.S. Energy Information Administration. Biorefineries produce about 15 billion gallons of ethanol a year.

In the last few years, some refineries began converting the inedible parts of corn plants into ethanol, Chundawat said.

 – The challenge is breaking down cellulose (plant) material, using enzymes, into sugars that can be fermented into ethanol. So any advances on making the enzyme processing step cheaper will make the cost of biofuel cheaper. This is a fairly intractable problem that requires you to attack it from various perspectives, so it does take time – he said.

Biomass contains lignin, an organic polymer that binds to and strengthens plant fibers. But lignin inactivates enzymes that bind to it, hampering efforts to reduce enzyme use and costs, according to Chundawat.

The Rutgers and Michigan State University researchers showed how specially designed enzymes (proteins) can limit their binding to and inactivation by lignin. That would ultimately lower enzyme use and make enzyme recycling feasible for biorefineries in the near future, Chundawat said.

Tesla To Install World’s Largest Grid-Scale Battery In South Australia

Tesla has announced that it will install the world’s largest grid-scale battery — 100 MW/129 MWh — in South Australia. The installation will be located in Jamestown in the north of the Australian state and will receive electricity to be stored from a wind farm operated by French energy company Neoen. Tesla broke the news late yesterday and CEO Elon Musk retweeted it out.

The story of how this project came to be is a fascinating tale. On September 28, 2016, freakishly high winds swept across South Australia, home to the city of Adelaide. The storm toppled a number of towers supporting the region’s high-voltage power lines, some of which connected South Australia to generating facilities in nearby Victoria. In the aftermath, members of the Australian government from the prime minister, Malcolm Turnbull, on down inexplicably blamed the blackout on too much renewable energy surging through its electrical grid.

This reaction came despite a statement by Australian Energy Market Operator, the grid operator, which categorically denied that renewable energy had anything to do with the blackout:

“There has been unprecedented damage to the network (i.e., bigger than any other event in Australia), with 20+ steel transmission towers down in the north of the State due to wind damage (between Adelaide and Port Augusta).

“The electricity network was unable to cope with such a sudden and large loss of generation at once.

“Australian Energy Market Operator’s advice is that the generation mix (i.e., renewable or fossil fuel) was not to blame for yesterday’s events — it was the loss of 1000MW of power in such a short space of time as transmission lines fell over.”

That statement was pretty clear, no? Nonetheless, it didn’t stop anti-renewables talking heads and media outlets from politicizing the unprecedented event.

Australia has enormous amounts of coal reserves, enough to meet its energy needs for 1,000 years. Some shortsighted leaders think it would be a great idea to dig up and burn all of that coal rather than fiddle around with newfangled ideas like wind turbines and solar panels.

Ever since last September, blackouts have afflicted the state of South Australia. That prompted Elon Musk in March of this year to offer to fix the area’s energy problem with a massive grid-scale battery. He boasted he could install such a system within 100 days of signing the necessary agreements. If not, the system would be free, Musk tweeted.

On July 7, Musk told the press in Adelaide that the project represented a significant challenge since it would be the largest grid-scale battery installation in the world “by a significant margin.” He added, “When you make something 3 times as big, does it still work as well? We think it will, but there is some risk in that. We’re confident in our techniques and the design of the system.”

Musk’s claim that the system will be 3 times larger than any other in the world represents a bit of hyperbole, something Musk is no stranger to. Tesla installed an 80 MWh system for Southern California Edison last year. That installation was completed in just over 90 days.

A Musk tweet today was more specific, indicating the tripling is in regards to power, not energy capacity.

To clarify, energy capacity (the MWh figure) is how much electricity the battery can store, whereas power capacity (the MW figure) concerns how quickly power can flow in or out of the battery. For more details on this topic, check out: “The Great ‘Power vs. Energy’ Confusion.”

Fed by the nearby wind farm, the Tesla battery system is expected to stabilize the grid and lower the price of electricity for utility customers.

“You can essentially charge up the battery packs when you have excess power when the cost of production is very low … and then discharge it when the cost of power production is high, and this effectively lowers the average cost to the end customer,” Musk said. “It’s a fundamental efficiency improvement for the grid.”

Tim Flannery of The Climate Council said South Australia was taking a leading role in Australia’s transition to renewable energy and storage technology. “South Australia is tackling climate change head on and should be congratulated for its innovation and leadership as it transforms our energy system into one that’s clean, affordable, efficient and secure. South Australians are witnessing first hand how swiftly this technology can be built and used, with the battery expected to be up and running this summer.

“South Australia joins the likes of California as a world leader in demonstrating how renewable energy and storage technologies can power our economy cheaply and cleanly. Renewables like wind and solar are now the cheapest power source available. We need to roll out this technology swiftly in a bid to tackle climate change.”

The End of the Combustion Engine? Volvo to Go All-Electric By 2019

Swedish carmaker Volvo has become the first traditional automotive firm to announce a full shift away from the internal combustion engine, as it today unveils plans for every Volvo car to have an electric engine from 2019.

In a move it described as a “new chapter in automotive history”, the company today promised that from 2019 all Volvo cars will either be fully electric, plug-in hybrid, or a “mild hybrid”, boasting a small petrol engine and a large battery.

“This is about the customer,” Håkan Samuelsson, president and chief executive, said in a statement. “People increasingly demand electrified cars and we want to respond to our customers’ current and future needs.”

The firm, which was bought by Chinese carmaker Geely in 2010, said it would also announce five fully electric new models between 2019 and 2021. Three will be manufactured under the Volvo brand and two under Polestar, the carmaker’s performance car arm.

Last month, Volvo confirmed Polestar would become a separate brand from Volvo, making high end EVs.

Alongside the new fully electric cars, a range of petrol and diesel plug-in hybrid and ‘mild hybrid’ 48 volt options will be available for all models.

“This announcement marks the end of the solely combustion engine-powered car,” Samuelsson added.

Today’s move provides more detail on how the carmaker plans to meet a target it set last year of selling one million electrified cars by 2025.

“When we said it we meant it,” Samuelsson said of the target. “This is how we are going to do it.”

As part of its original goal Volvo also promised to “promote acceptance” of EVs over the coming years by lobbying for more charging infrastructure and educating consumers on the benefits of the technology.

The global market for electric cars remains small, at just under one per cent of total new vehicle sales, but is growing rapidly. Across Europe registrations for new EVs grew 38 per cent in the first quarter of 2017, according to the European Automobile Manufacturers’ Association, and now command 3.2 per cent of the European market. Meanwhile, the US saw a 49 per cent jump in EV sales in the first quarter of 2017, according to Bloomberg New Energy Finance.

While Volvo is the first carmaker to announce plans to fully shift production away from pure combustion engine cars, many other major carmakers are pivoting their business models to focus more on the electric market. Jaguar, Audi, Aston Martin and Mercedes have all announced plans to launch new EV models in recent weeks, while Tesla has emerged as a global brand thanks to its focus on 100 per cent electric vehicles and clean energy.

Meanwhile, earlier this week Japanese carmaker Honda and Hitachi Automotive Systems announced plans to establish a new joint company focused on electric cars.

The company, backed with around five billion yen (£34m) of investment, will produce its own cars and sell electric vehicle parts to other carmakers.

Hitachi will have a controlling stake of 51 per cent of the new firm and Honda will have a 49 per cent share.

Hopes of Mild Climate Change Dashed by New Research

Hopes that the world’s huge carbon emissions might not drive temperatures up to dangerous levels have been dashed by new research.

The work shows that temperature rises measured over recent decades do not fully reflect the global warming already in the pipeline and that the ultimate heating of the planet could be even worse than feared.

How much global temperatures rise for a certain level of carbon emissions is called climate sensitivity and is seen as the single most important measure of climate change. Computer models have long indicated a high level of sensitivity, up to 4.5C for a doubling of CO2 in the atmosphere.

However in recent years estimates of climate sensitivity based on historical temperature records from the past century or so have suggested the response might be no more than 3C. This would mean the planet could be kept safe with lower cuts in emissions, which are easier to achieve.

But the new work, using both models and paleoclimate data from warming periods in the Earth’s past, shows that the historical temperature measurements do not reveal the slow heating of the planet’s oceans that takes place for decades or centuries after CO2 has been added to the atmosphere.

“The hope was that climate sensitivity was lower and the Earth is not going to warm as much,” said Cristian Proistosescu, at Harvard University in the US, who led the new research. “There was this wave of optimism.”

The new research, published in the journal Science Advances, has ended that. “The worrisome part is that all the models show there is an amplification of the amount of warming in the future,” he said. The situation might be even worse, as Proistosescu’s work shows climate sensitivity could be as high as 6C.

Prof Bill Collins, at the University of Reading, UK, and not part of the new research, said: “Some have suggested that we might be lucky and avoid dangerous climate change without taking determined action if the climate is not very sensitive to CO2 emissions. This work provides new evidence that that chance is remote.” He said greater long term warming had implications for melting of the world’s ice sheets and the rise of sea levels that already threatens many coastal cities.

The reason the historical temperature measurements indicated a lower climate sensitivity than models or paleoclimate data is because the Earth has a fast and a slow response to increases in carbon emissions, Proistosescu said.

Land, mostly in the northern hemisphere heats up quickly. But there is also a slow response, he said: “This is mostly associated with warming over the oceans. They are big and full of cold water, especially at depth, and take a long time to heat up.” Furthermore, when the slow warming does kick in, it is likely to reduce the cloud cover that shades the Southern ocean and the eastern tropical Pacific, amplifying the heating.

The new research shows the 4.5C upper limit for climate sensitivity is real and means projections for global temperature rises cannot be reduced. The global temperature is likely to be 2.6C to 4.8C higher by the end of the century if emissions are not cut, according to the Intergovernmental Panel on Climate Change, or 0.3C to 1.7C if sharp emissions cuts begin in the next few years.

The world may already be seeing the increasing rises in temperature, said Prof Piers Forster at the University of Leeds, UK: “It may already be happening – the rapid increase in temperatures since 2014 could be partly due to the eastern Pacific catching up.”

Reconciling all the estimates of climate sensitivity has also shown that climate models are not flawed. “Historical observations give us a lot of insight into how climate changes and are an important test of our climate models,” said Prof Peter Huybers, a colleague of Proistosescu’s at Harvard University. “But there is no perfect analogue for the changes that are coming.”

Swedish solar technology firm Sol Voltaics has raised $21.3m to help commercialise its new technology for boosting solar panel efficiency, delivering the largest finance raise for a European solar technology company since 2015.

The cash will be used to accelerate the rollout of the firm’s solar efficiency technology, SolFilm, which it claims can boost the efficiency of a conventional solar panel by up to 50 per cent.

“This latest round of finance gives us the critical capital required to commercialize our efficiency boosting technology for the solar market,” said Erik Smith, Sol Voltaics CEO, in a statement. “I’d like to thank our investors, both existing and new, for backing our vision and helping bring this revolutionary technology to the mass market.”

Solar panels generally achieve efficiencies of roughly 20 per cent, depending on their manufacturer and the environment in which they are deployed.

SolFilm is a thin film technology that uses specially designed nanowires to help solar manufacturers deliver panel efficiencies of up to 27 per cent.

The technology is in the “final stages” of commercialisation, according to Sol Voltaics, with samples expected to be sent to partners by the end of next year.

Investors in the latest finance round include Norwegian firm Watrium AS, Blue Marlin AB, and Nano Future Invest. It takes the total raised for Sol Voltaics over the last 12 months to $38m.

Danish wind energy giant DONG Energy has announced that it has signed a contract with wind turbine manufacturer Siemens Gamesa for the supply of 752 megawatts worth of wind turbines for the Borssele 1 and 2 offshore wind farm set to be developed in the Netherlands.

DONG Energy was awarded the right to build the Borssele 1 and 2 offshore wind farm back in July of 2016, which would have a capacity of 700 megawatt (MW). Located 22 kilometres off the coast of the Dutch province of Zeeland in water depths between 14 to 38 metres. At the time, the strike price for the project was an impressive €72.70 per MWh, however, as we’ve seen of late, prices have only continued to fall.

Announced on Thursday, DONG Energy revealed that they had signed a contract with newly-merged wind turbine company Siemens Gamesa for the supply of 94 of its 8 MW wind turbines, the nacelles of which will be assembled in Siemens Gamesa’s new factory in Cuxhaven, Germany. Meanwhile, the blades for the turbines will be produced in Hull, England. Both Borssele 1 and 2 are expected to be completed and fully operational by the end of 2020.

“With the signing of the wind turbine contract, we pass a key milestone in this project, which will be a landmark in the Netherlands’ shift to renewable energy,” said Jasper Vis, Country Manager for DONG Energy Netherlands. “This is an important step on our way to reducing the cost of renewable electricity in the Netherlands.”

“We are pleased that DONG Energy has selected Siemens Gamesa for the Borssele1 and 2 offshore wind power plants in the Dutch part of the North Sea,” added Michael Hannibal, CEO Offshore at Siemens Gamesa. “The advanced model of our proven direct drive offshore wind turbine platform and our advanced services will leverage the energy output of this lighthouse project and help to move offshore wind into the energy mainstream in Europe.”

Study Of Owl Wings Could Lead To Quieter Wind Turbines

The owl is one of nature’s stealthiest hunters. It flies through the air at great speed but in nearly total silence, giving its prey no clue that it is about to become a midnight snack. Scientists in Japan and China were curious about how owls can fly without making a sound. Their conclusions may have important implications for the renewable energy industry by helping to tame the slight noise wind turbines make as their giant blades slice through the air.

“Owls are known for silent flight, owing to their unique wing features, which are normally characterized by leading edge serrations, trailing edge fringes and velvet-like surfaces,” says Professor Hao Liu of Chiba University in Japan. “We wanted to understand how these features affect aerodynamic force production and noise reduction, and whether they could be applied elsewhere.” The study was published this week in the journal Bioinspiration and Biomimetics. The findings could lead the way to quieter operation of wind turbines, propeller driven aircraft, and multi-rotor drones.

The research required the use of advanced computer modeling. It analyzed mathematical models of owl wings with and without leading-edge serrations using large eddy simulations used in computational fluid dynamics to simulate air flows. They also used particle image velocimetry and force measurements in a low-speed wind tunnel. Very sophisticated stuff and evidence of the hidden wonders of nature that are all around us, largely invisible to mere mortals.

The studies revealed that leading-edge serrations can passively control the transition between laminar and turbulent air flow over an owl’s upper wing surface at angles of attack between zero and 20 degrees, which means they play a critical role in aerodynamic force and sound production.

“We found, however, that a tradeoff exists between force production and sound suppression. Serrated leading edges reduce aerodynamic performance at lower [angles of attack] than 15° compared to clean leading edges, but can achieve noise reduction and aerodynamic performance at [angles of attack] above 15°, which owl wings often reach in flight,” Professor Liu reports.

“These owl-inspired leading edge serrations, if applied to wind turbine blades, aircraft wings or drone rotors, could provide a useful biomimetic design for flow control and noise reduction. At a time when issues of noise are one of the main barriers to the building of wind turbines, for example, a method for reducing the noise they generate is most welcome.”

I don’t know much about computational fluid dynamics, but I did find this stunning video of an owl in flight that clearly shows the leading edge of its wings in action. Frighteningly beautiful stuff that may help make wind turbines more amazing in their quietude and help them get located closer to population centers.

Welsh Water is investing £250m to help produce its own energy needs and cut its £44m annual utility bill.

It has agreed the figure in a loan with the European Investment Bank (EIB) to cover some of its investment costs.

Bosses are meeting in Wrexham on Thursday at a waste water works it is turning into an energy park.

It is investing £36m to harness solar and hydro power at Five Fords, Marchwiel.

The company said it was also developing an advanced anaerobic digestion plant on the site, which will use waste to generate enough energy to supply about 3,000 homes.

Welsh Water, which serves Wales and Herefordshire, generates 20% of its own energy needs through wind, hydro, solar and anaerobic digestion technology.

It said the majority of its power was spent on pumping water and waste water through thousands of miles of pipes.

It has pledged to invest £1.7bn in its businesses between 2015-2020.

India’s Tata Power has announced the completion of a 187 megawatt (MW) hydro project in Georgia. The Shuakhevi Hydro Power Project was developed by Adjaristsqali Georgia LLC, a joint venture between Tata Power, Norway’s Clean Energy Invest and IFC InfraVentures.

Investment in the project exceeded $420 million, Tata Power said, and the facility is set to reduce greenhouse gas emissions by over 200,000 tons annually.

In a statement on Monday Tata Power’s CEO and managing director, Anil Sardana, said the project satisfied “Georgia’s electricity demand during winter, reducing dependence on imported fuel and increasing renewable energy output.”

Construction on the project began in 2013, with roughly 730 Georgians employed during the build.

“The Shuakhevi Hydro Power Project will contribute significantly to (the) energy independence of Georgia,” Prashant Joshi, CEO of Adjaristsqali Georgia LLC, said in a statement.

“We are supporting the strengthening of the energy sector with professional staff,” Joshi added. “Almost 90 percent of the Company’s employees are young Georgian engineers.”

According to the International Hydropower Association (IHA), hydropower represents over 80 percent of Georgia’s generating capacity and “between 75 to 90 percent of power generation, based on average hydrologic conditions.” The IHA adds that at the end of 2015 Georgia was home to over 70 operational hydropower stations, adding up to 2,727 MW in capacity.

European Union Reaffirms Commitment To Helping Pacific Islands Deal With Climate Change

Foto-ilustracija: Pixabay

The European Union has reaffirmed its full commitment this week to helping the Pacific Islands and territories deal with the negative impacts of climate change, further reiterating the European Union’s recent moves to publicly confirm the importance of the Paris Climate Agreement.

The move came at the inaugural meeting of the Climate Action Pacific Partnership held in Suva, Fiji, over the 3rd and 4th of July, which was organized in recognition of the need to support and strengthen the participation of Pacific Small Island Developing States (P-SIDS) in the global transition to a low-carbon economy and increase their participation in the global climate agenda. These P-SIDS states are made up of Federated States of Micronesia, Fiji, Kiribati, Republic of the Marshall Islands, Nauru, Palau, Samoa, Solomon Islands, Tonga, Tuvalu, Vanuatu, and my own country, and Papua New Guinea.

Out of the event held in Fiji earlier this week came key recommendations including the need to mainstream climate risk considerations and resilience across all policies, as well as in public and private investment and financing strategies.

The Pacific Island leaders also adopted a “Framework for Resilient Development in the Pacific (FRDP): an integrated approach to Climate Change and Disaster.” The Framework is designed to provide “high level strategic guidance to different stakeholder groups on how to enhance resilience to climate change and disasters, in ways that contribute to and are embedded in sustainable development.” The EU will thereby support this Framework and its implementation as well as “support the development of innovative approaches for linking climate actions taken by the public and private sectors and by civil society.” The P-SIDS leaders committed themselves to the Paris Agreement and the scientific basis behind the Agreement in a Statement published on Wednedsay.

Additionally, and speaking specifically to the danger of climate change, Fijian Prime Minister Frank Bainimarama announced that his country has offered to provide permanent refuge to the people of Kiribati and Tuvalu, two of the most climate-vulnerable Pacific nations, in the event that their atolls are subsumed by rising sea waters caused by climate change.

Looking at the role of the European Union, it is unsurprising that they have taken such a leading role, not just to continue an existing leadership role that the EU has been very proud of — and which is mirrored in the low-carbon transition in evidence in many large and small EU Member States — but to hit out at the move made by US President Donald Trump’s decision to withdraw his country out of the Paris Climate Agreement.

In the wake of the move, the European Union has repeatedly committed to reaffirm its support of the Paris Climate Agreement. In May, the EU, alongside 79 African, Caribbean, and Pacific countries, committed to defend and implement the Agreement, and a month later all the leaders of the European Union and its various presidents all reaffirmed their strong commitment to the Paris Agreement, and their desire to “swiftly and fully” implement the goals therein.

Additionally, and maybe most interestingly, we reported last week that German Chancellor Angela Merkel — arguably the EU’s most prominent leader and proponent — has made it clear she will likely confront the United States President over his isolationist policies, in particular the impact these policies have on global climate issues.

Greenpeace: Renewables to Undercut All Other Forms of Power Across the G20 by 2030

Renewables have been cheaper or equal in price to power from new coal or nuclear plants in around half of G20 countries since 2015, according to a new Greenpeace commissioned report, which predicts wind and solar power will outcompete all alternatives across the whole G20 by 2030.

The study, which was carried out by the Finnish Lappeenranta University of Technology, analyses electricity generations costs in all G20 countries from 2015 to 2030.

It found that onshore wind farms already undercut traditional power sources in large parts of Europe, South America, the US, China and Australia. It also argues that solar costs are falling so fast that the technology will undercut all other forms of power generation, including onshore wind by 2030.

The report cites growing evidence that renewables can outcompete new fossil fuel plants and nuclear projects in a growing number of countries.

“Last year, this average levelised cost of generating power from solar worldwide dropped 17 per cent, onshore wind power costs dropped 18 per cent and offshore wind power costs fell by 28 per cent according to a report commissioned by UNEP and BNEF,” the report states.

“Furthermore, in many countries RE has begun to undercut all other sources of new power generating capacity, with unsubsidised prices falling tonearly €26/MWh for a wind power project in Morocco and a bid of €24/MWh was made for a solar power plant in Abu Dhabi last year.”

Experts are increasingly confident that renewables costs are falling so fast they can still outcompete fossil fuels even when associated grid upgrade and balancing costs are considered.

The report follows a separate recent study from BNEF, which predicted renewables would provide nearly half of global power capacity by 2040 as wind and solar costs continue to fall sharply.

The analyst firm predicted solar power costs are set to fall a further 66 per cent by 2040, while onshore wind energy costs are expected to fall 47 per cent.

Greenpeace Germany energy expert Tobias Austrup said the latest study should come as a wake-up call for world leaders gathering for this weekend’s G20 Summit in Hamburg.

“There can be no excuses anymore. Climate protection increasingly makes economic sense across the G20 as renewable energy becomes cheaper than dirty coal and nuclear,” he said. “Any G20 country that is still investing in coal and nuclear power plants is wasting their money on technology that will not be competitive in coming years. The G20 now has a responsibility to send a clear signal that accelerating the clean energy transition is not only the right thing to do for the climate, but also for the economy.”

Report: Green Gas Could Now Power One Million Homes

Anaerobic digestion (AD) plants across the UK now produce enough green gas to power more than a million homes, according to an industry report released today by the Anaerobic Digestion & Bioresources Association (ADBA).

Capacity has jumped 18 per cent over the last year, the report found, bringing total AD capacity to 730MW (energy equivalent) with annual generation coming in at 10.7TWh of energy each year.

Improvements to operational performance, such as more consistent feedstocks, has also boosted load factors from 69 per cent to 73 per cent over the past year.

However, ADBA chief executive Charlotte Morton said the industry could do so much more if further government support was provided. “While it’s encouraging that the new government has committed to the Paris Agreement and to meeting the UK’s Carbon Budgets, there is currently a desperate lack of long-term policy support for AD, particularly in heat and transport, areas where AD can make a significant contribution to decarbonisation,” she said in a statement.

“While there are 437 AD plants in the planning stage, most of these are unlikely to be built without stronger government support for AD. This is a huge wasted opportunity – the government needs to act now to provide both short and long-term certainty for the AD industry to enable it to deliver the green energy the government urgently needs both to meet its legally binding climate change targets and for the UK’s energy security.”

ADBA claims policy uncertainty, from delays in updating the Renewable Heat Incentive to cuts in the Feed-in Tariff, is already having an impact on the number of new plants coming online. Between 50 and 80 plants were commissioned in 2016, but that number is projected to fall to between 19 and 64 this year due to policy uncertainty, the trade body warned.

Wind power generation capacity in Pakistan increasing rapidly as 13 projects with a cumulative installed capacity of around 650 MW have been installed and commissioned whereas 25 projects with cumulative capacity of around 1400 MW are in various stages of implementation.

Pakistan is developing wind power plants in Jhimpir, Gharo, Keti Bandar and Bin Qasim in Sindh as the cheap and environmental-friendly wind energy is gaining popularity. Alternative Energy Development Board of Pakistan has identified two wind corridors (of Jhimpir and Gharo) in the province of Sindh while the estimated potential for these two corridors is more than 50,000 MW.

On Monday, the National Electric Power Regulatory Authority (Nepra) has granted another generation license to wind power plant.

The Nepra granted generation license to the Iran-Pak Wind Power (pvt.) Limited (IPWPPL) for its wind farm with installed capacity of 49.50 MW located at Tapo Junqshahi, District Thatta, Sindh.

Main sponsor of the project include SUNIR (Iran Power & Water Equipment and Services Export Company) of the Islamic Republic of Iran whereas the minor sponsors include the Planet Group and the Tufail group of Pakistan.

SUNIR is an Iranian group company, constituted of 24 independent companies involved in manufacturing of a wide range of different equipment & a rich experience of engineering services & consultancy in water & electricity industries. Since its establishment in 1994, SUNIR has successfully performed a wide range of activities in more than 18 countries.

Energy Department of Government of Sindh issued Letter of Intent (Lol) for development of the project and also allocated to the sponsors 1250 acres of land in the Jhimpir wind corridor at Deh Kohistan 7/3 Tapo Jungshahi, Taluka & District Thatta, in the province of Sindh for setting up an approximately 50.00 MW generation facility/Wind Power Plant/Wind Farm.

For the implementation of the project, the sponsors have incorporated a special-purpose vehicle (SPV) in the name of IPWPPL.

The proposed project is based on Renewable Energy (RE) source and does not cause pollution as in the case of conventional power plants. However, the Nepra considers that the construction and operation of the generation facility/Wind Power Plant/VVind Farm may cause soil pollution and noise pollution. In this regard, the IPWPPL also carried out the Initial Environment Examination and submitted the same for the consideration and approval of Sindh Environmental Protection Agency (EPA), Government of Sindh while EPA has issued a No Objection Certificate (NOC) for the construction of the project.

The IPWPLL’s wind power plant will achieve Commercial Operation Date by June 30, 2019 and will have a useful life of more than twenty (20) years.

Proposed Wind Farm Off the Coast Could Generate 1,000 Megawatts

A major wind power project aims to capture the Central Coast’s wind and turn it into electricity. Trident Winds proposes to build a wind farm of 60 to 100 turbines off the coast, from Cayucos to north of Piedras Blancas.

Trident Winds founder Alla Weinstein presented her Seattle-based company’s case for the project June 20 at the Veterans Memorial Building. Before founding Trident, she led the company that developed the WindFloat floating foundation for deep-water offshore installations.

“Demand for energy continues to grow,” she said. “A convergence of factors leads to a need for more renewable energy. The technology is maturing.”

Weinstein said the project would be more than 20 miles offshore, to catch the winds and be out of sight, except from high on Hearst Castle’s hilltop, when lights would probably be seen at night. Together, the 600-foot-tall turbines would produce 1,000 megawatts of electricity. That power would reach the mainland through underwater transmission lines to the PG&E substation in Morro Bay.

The turbines would be tethered to the ocean floor by cables. The area targeted was chosen after weighing the overlapping interests in the area, from fishing grounds to the Point Mugu Missile Range, which impinges on part of the proposed site, and the fiber-optic cable corridor off Los Osos and Morro Bay.

It is outside the boundaries of the Monterey Bay National Marine Sanctuary, but in the migration path of gray and blue whales, elephant seals and other marine mammals. Pelagic birds might not be affected as much as land birds, which frequently fly into the whirling windmill blades on land.

“They navigate by changes in pressure, so they alter their route to fly around the turbines,” Weinstein said. “Pelagic birds are smarter than land birds.”

Environmental organizations filed comments to the initial request, posted on the Bureau of Ocean Energy Management’s website.

Weinstein said the wind off California’s coast represents a potential 112-gigawatt resource, compared to the two gigawatts that Diablo Canyon Nuclear Power Plant produces. According to the California Energy Commission, wind power is projected to fill some of the requirement for 50 percent of California’s Clean Energy and Pollution Reduction Act of 2015, which requires the state to get half of its electrical power from renewable energy sources by 2030. If everything falls into place — the project is subject to 33 permits and leases — it could be operational in 2025, Weinstein said.

Trident was the first company to apply for a lease to build a wind farm off the Central Coast. The land it would be leasing is in federal waters, so the Bureau of Ocean Energy Management is the responsible agency. Statoil, a Norwegian energy company, has since applied to compete for the lease. Weinstein’s presentation was a voluntary effort by Trident. Statoil has not yet offered to make its case to the public.

County Supervisor Bruce Gibson serves on the Bureau of Ocean Energy Management California Intergovernmental Renewable Energy Task Force, the panel of federal, state, local agencies and tribal governments collecting information to advise on decisions about future offshore renewable energy development in federal waters offshore California. He introduced Weinstein.

“The time is right for taking a look at energy offshore,” he said.

Solar Tops Poll of Most Desired Smart Home Technologies

Clean energy delivered by solar and battery storage systems has emerged as one of the most popular smart home solutions on the market, with 44 per cent of people saying they would like at least one of the technologies installed in their home by the end of the decade.

More than a third of people said they would want smart lighting installed, while 20 per cent opted for a voice-controlled smart hub and 13 per cent want to install a charging point for an electric car, according to a new survey released today by energy supplier E.ON.

The survey, conducted by OnePoll in April on behalf of E.ON, questioned 2,000 UK homeowners and found almost 73 per cent have already adopted some kind of smart home technology, from digital photo albums to smart thermostats.

Respondents cited saving money and becoming more energy efficient as some of the key drivers for installing smart technologies.

“It’s really heartening that three quarters of households have already taken steps to make their homes smarter,” Gavin Stokes, head of commercial solutions at E.ON UK, said in a statement. “But with a quarter of people saying they’re yet to take steps to make their homes more solutions-savvy, there’s still much we can do to help people realise the benefits a smarter lifestyle can bring.”

Solar may have emerged as a clear technology favourite, but the survey also found a patchy level of understanding about how the technology works.

Almost a fifth of those surveyed believe solar panels only generate electricity when it is sunny, while one in 10 people think solar panels do not work in colder climates – both common myths about the technology that developers and installers have struggled to dispel.

The survey comes as solar-plus-storage solutions are beginning to make their way onto the mainstream market. Firms including E.ON, Moixa, LG Chem, Tesla, North Star Solar, and MEP Werke are all offering solar-plus-storage solutions to domestic energy customers, with studies suggesting half of all EU citizens could be generating their own energy by 2050.

Advocates of the technology maintain it can maximise financial returns and emissions savings from solar installations and also potentially allow households and businesses to sell grid balancing services to grid operators. Providers of solar-storage systems are also increasingly confident that as costs fall the technology offering can prove attractive to customers without recourse to subsidies.

In related news, E.ON this week announced new plans to drive the growth of clean energy across its businesses with the creation of its own procurement and marketing functions for the German, British and Swedish markets. The teams will focus on purchasing power and gas for customers and marketing the production from renewable sources, E.ON said.

ALEKSANDRA TOMIC: The Introduction of Energy Managers a Big Step Forward for Serbia

In late September 2016, a conference on “Energy efficiency in public buildings in Serbia” was held at the hotel Metropol and was organized by GIZ, Ministry of Energy and Mining and the Faculty of Architecture. At this meeting, we learned more about the methodology of collecting and processing data on public buildings and comprehensiveness of this project, keeping in mind that in the last 20 years there were no investments in Serbian cities.

Among the speakers was also Ms. Aleksandra Tomic, PhD, who addressed the conference on behalf of the National Assembly of the Republic of Serbia. We talked to her in the building of the National Assembly, in the luxurious ambience of one of the three buildings that thanks to Ms. Tomic got an energy passport. The reason for our conversation is newly formed, informal parliamentary group called Serbian Parliamentary Energy Policy Forum. Ms. Tomic is the President of this group.

EP: The project “Energy efficiency in public buildings in Serbia” that GIZ supports is important for Serbia in terms of restoring public buildings, municipalities, schools and hospitals on the local level. You are involved in this project on behalf of the Parliament, so tell us what is the existing situation like and whether, in your opinion, the project can improve the situation on the local level.

Aleksandra Tomic: Within the cooperation between the German GIZ and NARS (National Assembly of the Republic of Serbia), which was established for monitoring implementation of the Law on the Rational Use of Energy, which the Serbian Parliament adopted on March 15th 2013, with particular emphasis on energy efficiency in buildings, Committee on the Economy, Regional Development, Trade, Tourism and Energy formed a Subcommittee to deal with these issues. Therefore, our cooperation lasts from 2013.

The Committee, which I chaired then realized that issues relating energy should be pointed out and set aside for the public to hear the truth about energy policies of all political actors in the world. Here, I have in mind EU countries and countries of the region in the first place, because they are an integral part of the political relations of the countries we cooperate with. Therefore, we have always been active participants in GIZ projects. In that way, we realistically represented all entities who seek for new legislation as MPs.

The relationship with local governments is an inseparable part of functioning of MPs, the Committee and NARS, with a special emphasis on the implementation of the new laws. They are not only the obligation of the authorities on the national level, but also authorities on the local level. GIZ really invested a lot of effort and the results are visible. However, the needs are much greater, because it is obvious that nothing has been done for 20 years in this area until 2012.

EP: Tell us more about the activities of the Serbian Parliamentary Energy Policy Forum that you lead. You have effective international activity, such as the Conference Bioenergy held on November 18th, 2016 in Belgrade. Also, you have plans for exchange with the German Parliament in June 2017. Why are these experiences important for us and whether the implementation of solutions from developed countries is possible in our legal system and energy?

Aleksandra Tomic: Serbian Parliamentary Energy Policy Forum is an informal parliamentary group which at this Assembly consists of 15 MPs. Meanwhile, another 14 MPs from several parliamentary groups submitted a request for membership. The Forum has 10 permanent members from the group consisting of 90 non-parliamentary members from other institutions: universities, companies, civil society organizations and the media. The activities of the Forum do not replace the activities of other institutions, but they are complementary. The Forum organizes events where the key actors in the energy sector meet, inform each other and discuss all the issues in the energy sector. Given the fact that MPs pass laws, open dialogue is necessary with all the actors who enable MPs to make decisions based on quality information that reflect numerous points of view. In this context, the meetings of Serbian Parliamentary Energy Policy Forum, is the place where all local, state, regional, European and other international actors in this field meet.

During these meetings, they exchange information and express opinions. In the last Assembly from 2014 to 2016, we had seven meetings and several conferences and other activities where we discussed
various issues. Some of these issues concern the possibility of using biomass for energy purposes, possible models of funding energy efficiency in buildings, as well as the topic in the field of mining and mining-geological research. Energy Development Strategy of the Republic of Serbia until 2025, with projections until 2030, we have considered at five simultaneously held panels, on which many journalists participated. Each participant had the opportunity to express their opinion, ask questions and participate in the discussion and the result is our recommendations of the
Forum that we submitted to the Ministry of Mining and Energy and published on the website of the National Assembly.

Clearly shaping energy policy objectives and creating opportunities for their achievement is a necessary perquisite for ensuring the economic development of Serbia. There is no economic development without good energy policy. Adequate setting of the targets enables the reduction of poverty, affects the increase in employment and the health of the nation. In a country like ours, with limited energy resources, limited human resources and without the ability to significantly influence global politics, it is not an easy task. A good energy policy enables a rational and efficient use of our limited resources, provides the ability to earn money, as well as heating and transport. I must say that events like conference COP21 influence the eventual review of the goals set forth in the Energy Strategy, which we adopted at the beginning of December 2015, and the objectives of the National Strategy for Sustainable Development we will have to revise as soon as possible.

EP: You have been involved in the preparation of energy passports for three significant buildings in Belgrade. How do you assess last year’s introduction of Energy Managers in the management system in our country, and the necessity of making energy passports?

Aleksandra Tomic: One of the results of the work of the Committee and Subcommittee, which I mentioned earlier, is also creation of energy passports for three most important buildings in Belgrade, which was conducted by the Faculty of Architecture in Belgrade based on the cooperation between GIZ and NARS. Buildings that have received energy passports are the edifice of the National Assembly of the Republic of Serbia, the Presidency of Serbia and the Palace of Serbia. These are the initial documents, without which you cannot start doing anything precise in the direction of reducing energy consumption. The introduction of Energy Managers in the system is a major step forward for Serbia. They are essential because they provide support to local governments in terms of personnel, in order to start developing energy passports for all the buildings owned by the Republic or local authorities. Regional Chamber of Commerce provides the assistance in obtaining certification of Energy Managers, which makes the inclusion of the economy in improving the process of introducing energy efficiency much higher. Otherwise, the law that introduced the function of Energy Managers in the system is a part of the EU standards, and this occupation is also considered to be one of the most popular and highest-paid not only in the EU but also in the world. If we want to reduce budget costs and increase public expenditure, and to use energy more rationally, this is a sure path to economic development of Serbia.
