Optimizing a Solar Array's Tilt and Module Spacing

System optimization is more than just good-looking charts - in this case, we are able to increase system profit by $40k, an increase of over 70% versus the 15ş-tilt baseline design.

Harvesting Energy From Heat

In the United States, more than half of the energy we burn each year gets lost as heat instead of being put to use with most of the energy going out the exhaust pipe of a car or out the smokestack of a power plant.

Q3 2014 Deal Volume Comparison

E.ON to quit gas and coal and focus on renewable energy

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.

Solar cloth could stretch PV's applications

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.

Wind energy provides more than 2/3 of new US capacity in October

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.

Why Google halted its research into renewable energy

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...

SunEdison, TerraForm to buy First Wind for $2.4B

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.
