Finance experts expect more initial public offerings (IPO) in the wind energy sector in 2014 after a year in which half a dozen companies on both sides of the Atlantic successfully raised nearly $2.3 billion by tapping the public equity markets. "It is hard to really predict how many will come out of the gate and actually get done. But there are 10-20 companies out there working on it, wondering if this is good source of low-cost capital for them and if they have what it takes to make a placement like this," says Michael Eckhart, global head of environmental finance with Citigroup. British fund Greencoat UK Wind started a wave of IPOs in March 2013, raising £260 million ($433 million). NRG Yield in the US and the Renewables Infrastructure Group (TRIG) in the UK followed in July with offerings of $431 million and £300 million, respectively. Canada's TransAlta Renewables completed a C$221 million (US$200 million) share sale in August, California-based Pattern Energy raised $352 million in October, and the UK's Infinis rounded up the year with a £234 million share sale in November.

Solar Energy - NRG Energy and MidAmerican Solar Complete Agua Caliente, the World's Largest Fully-Operational Solar Photovoltaic Facility
NRG Energy, Inc. (NYSE:NRG), through its wholly-owned subsidiary NRG Solar, along with partner MidAmerican Solar announced they have achieved substantial completion at their Agua Caliente Solar Photovoltaic Facility, a 290 megawatt (MW) photovoltaic facility located on 2,400 acres of land between Yuma and Phoenix, Ariz. The electricity that is generated by the station, which can support 230,000 homes at peak capacity, is being sold to Pacific Gas & Electric Company (PG&E) under a 25-year power purchase agreement. “Large-scale utility accomplishments, like our Agua Caliente project, raise the bar in terms of our clean-energy technology and production,” said Tom Doyle, president, NRG Solar. “Proving that we can build both the world’s largest solar thermal and now one of the world’s largest solar photovoltaic facilities advance NRG’s mission to reshape the energy landscape that is incredibly beneficial to both the economy and in how we produce and consume energy. Whether it’s partnering, developing or investing, NRG will lead the way in providing a diverse set of solutions and technologies to get the US to the ultimate goal of providing affordable, reliable clean energy for everyone.”
Scientists from the Japan Aerospace Exploration Agency (JAXA) have planned a series of pilot projects which, if successful, should culminate in a 1-gigawatt space-based solar power generator within just 25 years. Its energy output would be on par with some of the largest modern conventional power plants, thanks to fact that it’s above the atmosphere, which reflects or absorbs most solar energy that falls on Earth. Collecting solar power above the atmosphere means you could have access to almost 150% of surface amounts — and if we can find a way of beaming that power back down to Earth, our reliance on every other form of energy would vanish overnight. Here at ExtremeTech, we publish a fair number of articles about improvements to solar power. That makes sense since, until fusion power comes of age, solar will remain the only green technology that could even theoretically provide for our global power demands. The sun blasts our planet with so much power that the world’s deserts absorb more energy in a single day than the human race uses in a year. Yes, Earth’s surface is a phenomenal place to collect solar energy — but astronomers know about somewhere even better. Full Article:
Driven by an explosion in photovoltaics, the U.S. solar sector has emerged "from a relatively small contributor to the nation's total electric capacity into a one of comparative significance," the Energy Information Administration reported this week in its latest Electricity Monthly Update. Since 2010, EIA said, U.S. solar capacity increased 418 percent from 2,326 megawatts, accounting for 0.2 percent of total U.S. electric generation, to today's 12,057 MW, or 1.13 percent of U.S. generation. More than half of that additional capacity — 5,251 MW -- has been installed by home and business owners participating in utility net metering programs that allow owners of solar systems to sell excess capacity back to their local utility at retail rates, according to EIA. California has the largest net metered solar capacity, with 38 percent of the U.S. total, but Eastern states such as Massachusetts and New Jersey also have significant amounts of net metered solar energy, the agency said. Utility-scale PV applications, defined as systems with 1 MW or more of capacity, have also expanded significantly and currently account for 5,564 MW, according to EIA. Such systems generally are designed to generate power for wholesale markets.
Technological and market forces have converged to make energy storage one of the most exciting — and potentially game-changing — opportunities for commercial and industrial facility managers, grid operators, homeowners and investors. Forward-thinking utilities, battery suppliers, power inverter producers, system integrators and public-sector supporters are driving a massive expansion of energy storage solutions aimed at enabling the grid of the future — or even a grid-less future. Although the energy storage value chain includes hundreds — if not thousands — of players, the following are leading the charge.

President Obama will challenge companies Thursday to expand their use of solar power, part of his ongoing effort to leverage the power of his office to achieve goals that have been stymied by Congress. The new initiative comes as the White House is hosting a Solar Summit aimed at highlighting successful efforts on the local level to speed the deployment of solar energy. Although some large solar plants are coming online and it is the fastest-growing source of renewable energy in the United States, according to the U.S. Energy Information Administration, it accounts for roughly 1 percent of the nation’s electricity generation. “Now is the time for solar,” said Anya Schoolman, executive director of the Community Power Network, a Washington-based nonprofit group that helps communities build renewable energy projects. She will be honored at the summit Thursday. “The costs are affordable, in reach of middle America and above. We know how to do it now, we know how to scale it, and we kind of just need people to let it go and encourage it,” she said. In an effort to make it easier for state, local and tribal governments to expand their solar portfolios, the Energy Department is launching a $15 million-dollar “Solar Market Pathways” program.
Asia is now leagues ahead of other regions within the global wind market. Furthermore, this market is expected to grow at an annual cumulative capacity rate of more than 10 percent over the coming five years. A recent Global Wind Energy Council (GWEC) report shows other significant wind energy markets of the past few years have slowed in comparison. However, overall global growth of wind energy will remain firm with a hopeful measure of expanding growth again. The wind market for 2013 was an “off” year. Less wind energy capacity was installed in 2013 than in 2012. This disappointment saw the biggest drop in the market’s relatively short life. From 1996 through 2013, annual installed capacity for wind grew at an average rate of more than 20 percent.

A team of researchers at the Massachusetts Institute of Technology and Harvard University are working on a technology that wouldn't require sunlight to produce solar power. The team is developing a material that can absorb the sun's heat and store the energy in a chemical form, ready to be released "on-demand," according to a release. The technology could be used for heating buildings, cooking or other uses where heat, rather than electricity, is the desired output. In a release, researchers describe the technology behind the system: "Some molecules, known as photoswitches, can assume either of two different shapes, as if they had a hinge in the middle. Exposing them to sunlight causes them to absorb energy and jump from one configuration to the other, which is then stable for long periods of time.
