Spray-on Solar Cells - How do they Work?
Spray-on solar cells use nanotechnology. These cells are made using quantum dots, which is a nanocrystal composed of a semiconductor material that is small enough to take advantage of the laws of quantum mechanics.
Smog Eaters Are Coming To Our Roads
A reflective surface reduces smog by reflecting heat back into the atmosphere. Not only is the smog reduced, but more importantly, energy costs are lowered in big cities.
Deutsche Bank MD expects Cost of Solar to Drop Another 20-30% as 2020 Approaches
The US and China will be in the 12-15 GW range in 2015 but the incremental growth will come from some of these emerging markets. We expect Mexico to be a 2 GW market by 2017, with South Africa also above the 1 GW mark by 2017. These two markets were stagnant in 2013-14, so the growth will be quite significant in the coming years.

Google Is Making Its Biggest Ever Bet on Renewable Energy
Google Inc. is making its largest bet yet on renewable energy, a $300 million investment to support at least 25,000 SolarCity Corp. rooftop power plants.
Google is contributing to a SolarCity fund valued at $750 million, the largest ever created for residential solar, the San Mateo, California-based solar panel installer said Thursday in a statement.
Google has now committed more than $1.8 billion to renewable energy projects, including wind and solar farms on three continents. This deal, which may have a return as high as 8 percent, is a sign that technology companies can take advantage of investment formats once reserved only for banks.
“Hopefully this will lead other corporations to invest in renewable energy,” SolarCity Chief Executive Officer Lyndon Rive said in a phone interview.
The deal reflects the success of renewable energy companies in tapping into a broader pool of investors with financial products that emerged in the past three years, either paying dividends or sheltering cash. Those helped boost investment in clean energy 16 percent to a record $310 billion last year, according to data compiled by Bloomberg.
The Eiffel Tower now generates its own power with new wind turbines
France's most recognisable landmark, the iron Eiffel Tower erected in 1889, has seen its iconic frame festooned with many different decorations and objects over the years for various celebrations. Its latest addition is a little more subtle -- and maybe a little more in keeping with the tower's original purpose as a monument to human ingenuity and artistry.
As part of a major renovation and upgrade to the tower's first floor, the Société d'Exploitation de la Tour Eiffel will be adding a variety of sustainability features -- the first of which is a pair of VisionAIR5 wind turbines designed by renewable energy specialist Urban Green Energy.
The two vertical-axis turbines have been installed on the tower's second level, about 122 metres (400ft) from the ground -- a position that maximises wind capture. The turbines have been specially painted so as to blend in with the tower, and produce virtually no sound. They can also capture wind from any direction, producing, between them, a total of 10,000kWh per year -- enough to power the tower's first floor.
San Mateo County looks to ditch PG&E, jump into renewable energy movement
Aaron Kinney for Mercury News: In the latest sign that a Bay Area renewable energy trend is picking up steam, San Mateo County is taking a close look at buying its own power on the open market, instead of relying on PG&E, in a bid to lower its greenhouse gas emissions.
The county is exploring whether to establish a community choice aggregation program, which allows local governments to create their own energy portfolios that rely more on alternative sources like wind and solar and less on fossil fuels. On Tuesday, the board of supervisors will vote on allocating $300,000 toward a technical study of the proposal.
Marin County pioneered the community choice aggregation model in California. Since launching in 2010, Marin Clean Energy has grown to serve roughly 125,000 customers. The nonprofit claims it delivers more than twice as much renewable energy as PG&E at a slightly reduced cost to consumers.
Sonoma County followed suit last year with Sonoma Clean Power, and numerous jurisdictions are now looking into the model, including Alameda County and the South Bay cities of Cupertino, Mountain View and Sunnyvale.
Can Wind Energy Be Counted On To Help Meet Obama's Carbon Goals?
Ken Silverstein for Forbes: The wind energy sector is perpetually facing headwinds. But despite the challenges, those producers say that they are well prepared to help the country meet carbon reduction goals under the White House’s Clean Power Plan.
That plan, which was unveiled last summer and which will be finalized this June, will require a reduction in heat-trapping emissions of 30 percent by 2030. Such a goal is attainable given the shift from the heavily pollutive coal to natural gas-fired electric generation, which releases about half the carbon dioxide as coal. Nevertheless, the wind sector says that it can up the ante even more — if the current transmission system could be expanded to accommodate more electrons.
In an conference call, the American Wind Energy Association said that wind power has already exceeded the 2020 threshold that the Obama administration has outlined in its Clean Power Plan — and that it could blow past its 2030 goals, if the grid were expanded to the remote locations where many wind farms are getting built.
Moreover, “Some people think we need a battery attached to the wind,” says Michael Goggin, the association’s senior director of research. “All resources are backed up by all other resources on the power system. Changes in wind output are nothing new to grid operators.
UK approves world's biggest offshore wind farm
From Pilita Clark, Environment Correspondent for the Financial Times: The world’s biggest offshore wind scheme has been given the go-ahead off the coast of Yorkshire, in a move the government said was likely to create hundreds of jobs.
The Dogger Bank Creyke Beck project is expected to be one of the UK’s biggest power stations, second only to the Drax coal-fired plant in North Yorkshire and capable of supplying about 2.5 per cent of the country’s electricity.
The scheme’s developers have yet to take a final investment decision and the project will almost certainly have to secure backing under the government’s renewable energy subsidy system.
But the government’s planning consent for such a large development was welcomed by the industry.
“This is an awesome project,” said Nick Medic, director of offshore renewables at RenewableUK, the wind industry trade body. “It will surely be considered as one of the most significant infrastructure projects ever undertaken by the wind industry.”
If built, the scheme will dwarf the London Array in the outer Thames Estuary, currently the largest operating offshore wind farm, with 175 turbines.

Europe Wind Power Booms on German Demand as 2015 Set for Record
Developers installed 11.8 gigawatts of wind turbines in Europe last year, accounting for almost half the power-generation capacity added, as the region continues to shift away from fossil fuels, according to the European Wind Energy Association.
Germany was the top wind market with about 45 percent of the total, the Brussels-based trade group said Tuesday in a statement. It was followed by the U.K., Sweden and France, with the four countries accounting for more than three-quarters of the industry.
Wind power in southern Europe will “continue to struggle in the face of erratic and harsh changes in the policy arena,” Thomas Becker, EWEA’s chief executive officer, said by e-mail. “We expect this concentration to continue into 2015.”
Wind power made up 43.7 percent of all new capacity in Europe last year. Turbine installations this year may reach a record 15.6 gigawatts as developers seek to qualify for government incentives, according to Bloomberg New Energy Finance. A gigawatt of capacaity is about as much as one nuclear reactor.
