The roads constructed using this technology are more durable and economical than the conventional bitumen roads.
Germany’s biggest utility firm, E.ON, has announced plans to split in two and spin off most of its power generation, energy trading and upstream businesses, responding to a crisis that has crippled the European energy sector. E.ON said it wanted to focus on its renewable activities, regulated distribution networks and tailor-made energy efficiency services, citing “dramatically altered global energy markets, technical innovation, and more diverse customer expectations”. “E.ON’s existing broad business model can no longer properly address these new challenges,” the chief executive, Johannes Teyssen, said in a statement. Germany’s power sector has been in turmoil, hit by a prolonged period of weak demand, low wholesale prices and a surge in renewable energy sources which continue to replace gas-fired and coal-fired power plants. E.ON said it would prepare next year for the listing of the new company created by its breakup, with the spin-off taking place after its 2016 annual general meeting.
A British start-up has developed a way for parking lots and structures with roofs that can’t take much weight to harness the power of the sun. The Cambridge, England-based Solar Cloth Company is beginning to run trials of its solar cloth, which uses lightweight photovoltaic fabric that can be stretched across parking lots or on buildings that can’t hold heavy loads, such as sports stadiums with lightweight, retractable roofs. Perry Carroll, Solar Cloth Company’s founder, told BusinessGreen that the company is working to close deals to install solar cloth on 27,000 parking lots. “We have built a growing sales pipeline worth £4.2m [about $US6.57 million] for 2015, including park and ride projects, airport parking operators and retail park owners,” he said. According to Solar Cloth Company, there are about 320 square miles of roof space and 135 square miles of parking space in the UK that could be covered by solar cloth, and if all of these spaces were covered, the solar power produced would be enough to power the UK’s grid three times.
According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects, wind power provided over two-thirds (68.41%) of new U.S. electrical generating capacity in October 2014. Specifically, five wind farms in Colorado, Kansas, Michigan, Nebraska, and Texas came on line last month, accounting for 574MW of new capacity. In addition, seven "units" of biomass (102MW) and five units of solar (31MW) came into service accounting for 12.16% and 3.69% of new capacity respectively. The balance came from three units of natural gas (132MW - 15.73%). Moreover, for the eighth time in the past ten months, renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) accounted for the majority of new U.S. electrical generation brought into service. Natural gas took the lead in the other two months (April and August). Of the 9,903MW of new generating capacity from all sources installed since January 1, 2014, 34 units of wind accounted for 2,189MW (22.10%), followed by 208 units of solar - 1,801MW (18.19%), 45 units of biomass - 241MW (2.43%), 7 units of hydropower - 141MW (1.42%), and 5 units of geothermal - 32MW (0.32%). In total, renewables have provided 44.47% of new U.S. electrical generating capacity thus far in 2014.
Back in 2007, Google had a very simple idea for addressing global warming — we just need to take existing renewable-energy technologies and keep improving them until they were as cheap as fossil fuels. And, voila! Problem solved. That was the logic behind the company's RE-C project, which aimed to produce one gigawatt of renewable electricity for less than the price of coal. The hope was to do this within years, not decades. Among other things, the company invested in new geothermal drilling R&D and put $168 million toward Brightsource's Ivanpah solar tower in the Mojave Desert. By 2011, however, Google decided that this "moon shot" energy initiative wasn't going to work out as planned and shut things down. So what happened? In a long essay at IEEE Spectrum, two Google engineers on the project — Ross Koningstein and David Fork — explain the thinking behind the closure. It's not that Google has given up on renewable energy. (The company still spends many millions of dollars buying wind energy for its servers.) Partly it's that they simply weren't on track to achieve their specific goals. But, more interestingly, the project also made the engineers realize that their original clean-energy goal wasn't nearly ambitious enough. Cont'd...
Solar company SunEdison and unit TerraForm Power said they would buy First Wind for $2.4 billion to enter the U.S. wind power market. SunEdison's shares rose 6.6 percent to $17.70, while TerraForm shares rose 1.2 percent to $26.15 in after-market trading. The deal comprises $1.9 billion in upfront payment and $510 million in earn-outs, the companies said. Boston-based First Wind is operating or building renewable energy projects in the Northeast, the West and Hawaii, with a combined capacity of nearly 1,300 megawatts (MW) - enough to power more than 425,000 homes each year. SunEdison raised its 2015 installation forecast to 2.1-2.3 gigawatts (GW) from 1.6-1.8 GW. TerraForm increased its 2015 dividend forecast to $1.30 per share from 90 cents. TerraForm was created by SunEdison to own and operate its solar power plants. TerraForm went public in July. The deal is expected to close during the first quarter of 2015, the companies said.
In this paper, we look at the current state of value of solar (VOS) analysis and propose a more holistic methodology that can be consistently applied across various utility service areas.
From high efficiency to scalability, fuel cells provide a distinct advantage over incumbent energy generation technologies, which is why top companies, governments, and the military are adopting fuel cells for everyday use.
The decisions of the European Council indicate the desire for greater integration of European energy markets, with an integration target of 10% by 2030.
The end of the year is a very busy time for Renewable Energy Tradeshows, so come January the schedule slows down a bit.
According to a new study by Berkeley Lab, distributed solar photovoltaics (PV) are the most immediate threat to investor-owned utilities and their shareholders, by depleting revenue from demand growth and need for capital investments in traditional power plants.
Denmark, a tiny country on the northern fringe of Europe, is pursuing the world’s most ambitious policy against climate change. It aims to end the burning of fossil fuels in any form by 2050 — not just in electricity production, as some other countries hope to do, but in transportation as well. Now a question is coming into focus: Can Denmark keep the lights on as it chases that lofty goal? Lest anyone consider such a sweeping transition to be impossible in principle, the Danes beg to differ. They essentially invented the modern wind-power industry, and have pursued it more avidly than any country. They are above 40 percent renewable power on their electric grid, aiming toward 50 percent by 2020. The political consensus here to keep pushing is all but unanimous. Their policy is similar to that of neighboring Germany, which has spent tens of billions pursuing wind and solar power, and is likely to hit 30 percent renewable power on the electric grid this year. But Denmark, at the bleeding edge of global climate policy, is in certain ways the more interesting case. The 5.6 million Danes have pushed harder than the Germans, they have gotten further — and they are reaching the point where the problems with the energy transition can no longer be papered over.
The controversial government program that funded failed solar company Solyndra, and became a lighting rod in the 2012 presidential election, is officially in the black. According to a report by the Department of Energy, interest payments to the government from projects funded by the Loan Programs Office were $810 million as of September - higher than the $780 million in losses from loans it sustained from startups including Fisker Automotive, Abound Solar and Solyndra, which went bankrupt after receiving large government loans intended to help them bring their advanced green technologies to market. The report's findings are more of a political victory than a financial one. It took the program three years to break even after Solyndra's failure, while during that same time the Standard & Poor's 500 index increased 67 percent. Still, the federal loans program is a success for taxpayers, judging by the numbers in the new report, the DOE said. After Solyndra's 2011 collapse, the program was sharply criticized by Republican lawmakers as a waste of public money and a fountain of cronyism. The outcries mounted as others in the program failed, and the DOE issued no new loans between late 2011 and this year. "Taxpayers are not only benefitting from some of the world's most innovative energy projects... but these projects are making good on their loan repayments," Peter Davidson, executive director of the Loan Programs Office, said in an interview on Wednesday. Davidson took over the loan program in May of 2013.
Climate-conscious Americans have long glanced enviously across the Pacific to China and its ever-growing number of often-gargantuan wind farms. It turns out that they have less to be jealous about than previously thought: The United States has more wind energy powering its grid than any other country in the world, says a report by EDF Renewable Energy, the largest third-party provider of operations and maintenance for wind renewable-energy projects in the country. Though China has more megawatts of wind turbines installed than the U.S—about 90,000 to America's 60,000—the U.S. actually produces more electricity that is delivered to the grid, which in turn reaches more businesses and homes. And while China's wind industry delivered less than 138 billion kilowatt-hours in 2013, the U.S.'s delivered more than 167 billion. That's 20 percent more than China. And the U.S.'s generation has been growing steadily since 2008, when it first overtook Germany to become the world's No. 1 producer.
Google, Yahoo and Microsoft are part of a growing number of tech and other major companies that are entering into long-term “power purchase” agreements (PPAs) with wind farms to ensure a steady stream of power, at a fixed cost, over a period as long as several decades. Most recently, last month Yahoo signed such a deal for wind power in the Great Plains with OwnEnergy, a wind energy developer. Google -- which is already carbon neutral and now trying to power itself with “100 percent renewable energy” -- has the longest history here. It has three PPA deals in the U.S. wind sector (in Iowa, Oklahoma, and Texas), and two more in Sweden. Microsoft, meanwhile, currently has two PPA deals with wind installments located near its data centers in Texas and Illinois. The agreements provide 285 megawatts of power to help drive both Bing searches and also its other online platforms, according to Brian Janous, the company’s director of energy strategy. What these deals have in common is that they involve purchasing clean energy in close proximity to the power hungry data centers that these companies operate -- data centers that in turn drive searches, apps like Gmail and much more. “These are very energy intensive operations that these companies are planning on running for years, and they know they need electricity,” says Emily Williams of the American Wind Energy Association.
