Despite the series of withdrawals of greentech IPOs this month, solar rooftop installer SolarCity announced on Monday that it is planning for an IPO. The company says it filed its IPO registration on April 26, and is waiting for the documents to be reviewed and approved by the SEC. A SolarCity IPO has been an open secret for the past few months and a report in Bloomberg in February said that an IPO could value SolarCity at more than $1.5 billion. Back in February SolarCity also raised $85 million from investors like Silver Lake Kraftwerk to expand its rapidly growing solar rooftop empire. Overall, SolarCity has raised just over $200 million in venture capital, company spokesman Jonathan Bass told us back in February.
Donald Trump swept into Scotland's parliament on Wednesday to demand the country end plans for an offshore wind farm he fears will spoil the view at his exclusive new $1.2-billion golf resort. In a typically blunt display, the property tycoon told an inquiry into renewable energy to stop the wind power efforts in the country's north. "Scotland, if you pursue this policy of these monstrous turbines, Scotland will go broke," he said. "They are ugly, they are noisy and they are dangerous. If Scotland does this, Scotland will be in serious trouble and will lose tourism to places like Ireland, and they are laughing at us." When challenged to produce hard evidence about his claims on the negative impact of turbines, Trump said: "I am the evidence, I am a world-class expert in tourism." The public gallery burst into laughter.
This project has been developed by Gujarat State Electricity Corporation Limited (GSECL), with full support from Sardar Sarovar Narmada Nigam Limited (SSNNL) which is the nodal agency behind construction of the Naramda canal that brought agricultural prosperity to the State. The engineering, procurement and construction contract for the project has been awarded to Sun Edison, a subsidiary of US-based global solar energy player, MEMC. The 750 metre stretch of the canal will generate 1.6 million units of clean electricity per year, as well as prevent evaporation of 900,000 litres of water per year from the canal. Today, Gujarat has about 458 kilometres of open main canal, while the total canal length including sub-branches is about 19,000 kilometres; the final aim of SSNNL is to construct a total of 85,000 kilometres of canal network. Assuming a utilization of only 10% of the existing canal network of 19,000 kilometres, it is estimated that 2,200 megawatts of solar power generating capacity can be installed. This implies that 11,000 acres of land which would otherwise be needed to site solar panels as well as 20 billion litres of water per year can be potentially conserved.
The outlook for US wind power growth is cloudy and negative with the wind production tax credit (PTC) due to expire at year-end. The wind power forecast for 2012 is decidedly better north of the US border, in Canada, however. Canada’s wind power market should experience another year of record-setting growth in 2012, with the addition of some 1,500 MW of additional capacity, according to a Canadian Wind Energy Association (CanWEA) study released at the Global Wind Energy Council (GWEC) annual conference in Copenhagen. Canada’s wind energy industry enjoyed a record year in 2011, installing around 1,267 MW of new capacity, an investment of $3.1 billion that created some 13,000 person-years of employment. That ranks 6th globally with a total wind energy capacity of 5,403 MW, enough to power more than 1.2 million homes, according to CanWEA and the GWEC’s 2011 annual industry reports.
Data centers guzzle down 2% of the electric grid’s capacity and run up $2 billion worth of monthly utility bills. Furthermore, it’s estimated that by 2020, CO2 emissions from data centers will top the emissions by the airline industry. How do we get the cloud under control? One solution might be improving the efficiency in how data centers draw electricity in from the grid. A recent post from GE Reports takes a look at how 99% of this electricity could be pulled in more efficiently by bypassing ‘filters’ when they’re not absolutely necessary. If all data centers (‘the cloud’) did this, we’d be able to save 4,000 megawatts of electricity worth more than $3 billion per year.
The U.S. wind industry installed 6,816 megawatts (MW) in 2011, 31 percent higher than 2010, for a total of 46,916 MW installed to date, the industry's trade group said in a release Thursday. Setting the stage for a strong 2012, the American Wind Energy Association (AWEA) also said there were more than 8,300 MW of wind power under construction across the United States. The nation has about one million megawatts of generating capacity with about 400,000 MW coming from natural gas burning plants, 300,000 MW from coal, 100,000 MW from nuclear, 80,000 MW from hydropower, 50,000 MW from oil and the rest mostly from wind and other renewables. One megawatt powers about 1,000 homes. Wind and natural gas are the two largest sources of new generating capacity in the United States. Wind has provided about 35 percent of new U.S. power capacity over the past five years, AWEA said. Full Article:

Earlier this week algae fuel startup Sapphire Energy announced that it’s in the process of raising a whopping $144 million from private investors, which will be used to build out its first commercial demonstration algae farm in New Mexico. That farm could be able to produce 1.5 million gallons of Sapphire’s green crude per year by 2014, says Sapphire’s VP of Corporate Affairs, Tim Zenk. That might sound impressive, but it’s a far cry from the company’s previous projections. Back in 2009, Sapphire was hoping its algae farm would be able to produce 1 million gallons of green crude per year by 2011, followed by 100 million gallons per year by 2018, and 1 billion gallons per year by 2025. When Sapphire made those projections, the sheer volume was so much more than any of their competitors were putting out there, that I asked if Sapphire was going to be “the gorilla of algae fuel?“ Full Article:
According to the most recent issue of the "Monthly Energy Review" by the U.S. Energy Information Administration (EIA), with data through December 31, 2011, renewable energy sources expanded rapidly during the first three years of the Obama Administration while substantially outpacing the growth rates of fossil fuels and nuclear power. Between January 1, 2009 and December 31, 2011, renewable energy sources (i.e., biofuels, biomass, geothermal, solar, water, wind) grew by 27.12%. By comparison, during the same three-year period, total domestic energy production increased by just 6.72% with natural gas and crude oil production growing by 13.66% and 14.27% respectively. Moreover, during the same period, nuclear power declined by 1.99% and coal dropped by 7.16%. Full Press Release:
Japan is preparing to bolt turbines onto barges and build the world’s largest commercial power plant using floating windmills, tackling the engineering challenges of an unproven technology to cut its reliance on atomic energy. Marubeni Corp. (8002), Mitsubishi Heavy Industries Ltd. (7011) and Nippon Steel Corp. (5401) are among developers erecting a 16-megawatt pilot plant off the coast of Fukushima, site of the nuclear accident that pushed the government to pursue cleaner energy. The project may be expanded to 1,000 megawatts, the trade ministry said, bigger than any wind farm fixed to the seabed or on land. “Japan is surrounded by deep oceans, and this poses challenges to offshore wind turbines that are attached to the bottom of the sea,” Senior Vice Environment Minister Katsuhiko Yokomitsu said at a meeting in Tokyo this month. “We are eager for floating offshore wind to become a viable technology.” Full Article :
The California Public Utilities Commission and NRG Energy (NYSE: NRG) have entered into an agreement where NRG will build a comprehensive electric vehicle (EV) charging network in California, investing approximately $100 million over the next four years. "And we will be helping the State meet its clean car goals as embodied by its Zero Emission Vehicle (ZEV) mandate." This fee-based charging network will consist of at least 200 publicly available fast-charging stations—installed in the San Francisco Bay area, the San Joaquin Valley, the Los Angeles Basin and San Diego County—which can add 50 miles of range in less than 15 minutes of charging. Additionally, NRG's EV infrastructure commitment will include the wiring for at least 10,000 individual charging stations located at homes, offices, multifamily communities, schools and hospitals located across the State.

Global PV cell production grew to an impressive 37.2 GW in 2011, according to a market survey by PHOTON International - The Solar Power Magazine, for a 36-percent increase over the 27.4 GW produced in 2010. But the annual survey also reveals a dramatic reduction in year-on-year growth. Compared to a record 120-percent jump in 2010, the 2011 cell output was the PV industry's lowest growth rate since a 34-percent increase in 2003. The survey also shows a continuation of Asian dominance, with six Chinese manufacturers in the top 10 - with Suntech Power in first place for the second year in a row - and two from Taiwan. For the first time since PHOTON International began surveying solar cell producers, the top 10 did not include any solar cell producers from Europe or Japan. "The days of solar cell production in western countries are numbered," says Michael Schmela, editor-in-chief of PHOTON International. "Like other commodities, solar cell production will continue its rapid shift to low-labor-cost countries in Asia, especially China." In 2008, only 33 percent of solar cells were made in China, a share that grew to an impressive over 57 percent in 2011. Full Press Release:
In an effort to find a visual counterpart to his rhetoric on energy, President Barack Obama is speaking at four types of energy production facilities in two days, each site representing a facet of his energy plan. "I'll be talking about what we're calling an all-of-the-above energy strategy -- all of the above," Obama said, previewing his trip before a crowd gathered at a solar facility in Boulder City, Nevada. "A strategy that relies on producing more oil and gas here in America, but also more biofuels, more fuel-efficient cars, more wind power and, as you can see, a whole lot more solar power." The visit to Boulder City on Wednesday was designed to tout the success of solar technology at the largest photovoltaic solar facility in the nation. Photovoltaic solar panels create energy directly from sunlight without the need for any water or moving parts. Full Article:
President Barack Obama's administration is expected to throw its weight behind U.S. solar panel producers on Tuesday in their battle against lower-priced imports from China that they say threaten the future of the industry in the United States. A coalition of seven U.S. manufacturers has asked for duties topping 100 percent on Chinese-made solar cells and panels, which they say are subsidized by the Chinese government and "dumped" in the United States at unfairly low prices. The case, which was filed last year, has created more friction in the U.S.-China trade relationship, already strained by clashes over Beijing's currency policies and U.S. duties on a number of other Chinese goods.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
