Why You Should Be Paying Attention To The 'Other' Form Of Solar Power
Joe Romm for ThinkProgress: Solar photovoltaic (PV) systems have seen explosive growth because of their stunning 99 percent price drop in the past quarter century. As a result, the other form of solar power — concentrating solar thermal power (CSP) — is a small fraction of the solar market.
But the International Energy Agency (IEA) says CSP has a very bright future too because it enables cheap, efficient storage, which allows CSP plants to provide electricity long after the sun has set. According to the IEA’s 2014 CSP Technology Roadmap, 11 percent of global electricity will be generated by concentrating solar thermal power in 2050. Cont'd...

The Trillion Dollar Drone
Drones will eventually be "as ubiquitous as pigeons", London-based futurist Liam Young recently predicted. They will be used for a lot of different tasks. One overlooked drone application even has the potential to become a trillion dollar business. And to save the world.
Can bladeless wind turbines mute opposition?
Dominic Bates for The Guardian: A new bladeless wind turbine that promises to be more efficient, less visually intrusive, and safer for birdlife than conventional turbines has been welcomed by two of the UK wind energy industry’s most vocal critics.
The RSPB and the Campaign to Protect Rural England (CPRE), which have both expressed concerns over the impacts of industrial-scale windfarms on the landscape and wildlife, said the new turbine was encouraging news for birds and had the potential to open up more urban environments to the sector.
The streamlined design contains no contacting moving parts, making it virtually noiseless and less prone to vibration. Vortex Bladeless, the turbine’s Spanish developers, hopes these advantages could finally help usher in a viable consumer wind power market.
“Wind turbines now are too noisy for people’s backyard,” says David Suriol, who co-founded the company with Raul Martin and the turbine’s inventor, David Yáñez. “We want to bring wind power generation to people’s houses like solar power.”

Berkeley lab unveils new solar energy center aimed at producing fuel from sunlight
Jeremy Thomas for Inside Bay Area News: In a christening hailed as a key moment in the effort to harness the sun's energy to create fuel, Lawrence Berkeley Lab officials on Tuesday unveiled a $59 million Solar Energy Research Center.
Named after former Energy Department Secretary and Lab Director Steven Chu, the 40,000-square-foot Chu Hall will be a place of world-changing research in producing cheaper, more efficient renewable energy to replace fossil fuels, said Chu, who was honored for inspiring the mission.
"This is one of the most important problems that science, technology and innovation really need to solve," Chu said. "It's a very big deal. ... We simply need to save the world, and it's going to be science that's going to be at the heart of that solution."
The facility will be home to the Berkeley hub of the Joint Center for Artificial Photosynthesis, a Department of Energy-funded collaboration led by the California Institute of Technology that is attempting to create solar fuel as plants do by using sunlight and other catalysts to split water into hydrogen and oxygen gas and convert carbon dioxide into liquid fuels such as methanol and ethanol. The byproduct of producing such a fuel would be oxygen.
Why one company sees great potential in the U.S. offshore wind market
By Jaclyn Brandt for FierceEnergy: In April, DONG Energy signed an agreement to take over RES Americas Developments Inc.'s (RES) more than 1,000-megawatt (MW) development project rights off the coast of Massachusetts. RES had secured the rights to two leases from the U.S. Bureau of Ocean Energy Management (BOEM) in January.
"The U.S. is an interesting market for offshore wind with the potential to become a significant area for future development," said Samuel Leupold, executive vice president of Wind Power with DONG Energy, said at the announcement in April. "We already have a number of post-2020 projects in our pipeline in North-Western Europe that we will continue to develop. With the takeover of the offshore wind development project in the US, we will broaden our geographical scope and follow the market potential outside of our current footprint."
Leupold continued, "The site conditions are quite similar to those we currently work with in North-Western Europe which means that the project could be developed using well-known technology and logistics."
Although the offshore wind market in the United States has many regulatory obstacles, Brostrøm said that there is also a lot of potential off the East Coast -- including good wind speeds and water depths. He also cited the efforts by BOEM to encourage wind development.
This cloudy-day black silicon solar cell can hit a record 22.1% efficiency
Researchers at Finland’s Aalto University have achieved a record-breaking 22.1% efficiency for a nanostructured silicon, or black, solar cell. They accomplished this by overlaying a thin, passivating film on the nanostructures by a process known as atomic layer deposition, and by integrating all of the metal contacts on the cell’s back side.
Perhaps the best part: Black solar cells work really well on cloudy days. “This is an advantage particularly in the north, where the sun shines from a low angle for a large part of the year,” said professor Hele Savin from Aalto University, who coordinated the study, in a statement. “We have demonstrated that in winter Helsinki, black cells generate considerably more electricity than traditional cells, even though both cells have identical efficiency values.”
Using the aforementioned process, the team managed to beat their previous record by almost 4%, which is a stunning achievement. The new cells have a certified external quantum efficiency of 96% at 300nm wavelengths, which the team said shows that charged carrier surface recombination is no longer a problem — and that for the first time, the black silicon isn’t limiting energy conversion efficiency. And thanks to the inherent properties of black solar cells, they can capture solar radiation at low angles, generating more electricity over the full duration of a day as compared with traditional cells.
The Thin Film Solar Cell Industry In Transition: Knockout Phase Is Over - Profitability And Vertical Integration Next
The implementation of PV into buildings should not be considered an added novelty product supplementing current construction materials, but rather be seen as an integrated part of roofing and facade material that could add substantial value to building material suppliers' range.
A highlight of WINDPOWER 2015
U.S. energy secretary, Dr Ernest Moniz, spoke at the Opening General Session at AWEA’s WINDPOWER 2015 event today in Orlando, Florida. Moniz stressed that wind power is an important and necessary part of the solution to climate change. Wind could provide five times what it provides today, he said, with a goal of one trillion kilowatt-hours per year in America.
To get there, new technologies are needed to boost the industry is areas where it is not yet cost-effective or as profitable as other energy sources. Moniz mentioned better siting methods, improved drivetrains, and longer blades. On the show floor, companies are certainly bringing some new and improved technologies to the wind market.
