AROA’s Second Solar Tulip Power Plant Springs Up in Spain

By Andrew Michler

Clean tech company AROA recently installed their second energy-generating Solar Tulip power tower in Spain, and the soaring flower-shaped power plant just went online this week. The beauty of the system stems beyond the elegant solar energy capturing tower – the system is designed to be modular, unlike any other concentrated solar power (CSP) electrical generator out there. The system also uses much less water than steam solar generators, enabling it to conserve precious resources on its hot desert site.

World's largest offshore wind farm opens for business

By

Walney wind farm off the coast of Cumbria in the UK yesterday became the world’s largest offshore wind facility. One hundred and two turbines over 73 sq km (28 sq miles) provide a maximum output of 367.2 MW. It’s claimed the facility will provide enough power for about 320,000 homes – half as many again as the total number in Cumbria.

The project’s first phase, Walney 1, has been providing power since January 2011 from 51 137-meter-high (450-ft) turbines, each with a 107-m (350-ft) rotor diameter. The completed second phase, Walney 2, adds another 51 turbines of even greater size to the installation. These 150-m (492-ft) tall turbines have three 18-tonne (19.8-short ton) blades with a total diameter of 120 m (394 ft). Despite the differing dimensions, all turbines are Siemens-made 3.6 MW turbines. All told a single wind turbine weighs a hefty 550 tonnes (606 short tons). The Walney 2 installation was completed in an impressively tight six-month window.

Why Google Invests in Clean Energy

Email, RSS Follow

Last year, Google invested more than $915 million in clean energy projects — solar, wind and transmission.

That’s a lot of money, even for Google, which had $38 billion in revenues in 2011. The investments don’t appear to be core to the company’s mission of organizing information, and they have attracted criticism, as well as some careless reporting, implying that the Internet giant is exiting the alternative energy business.

Military bases in Mojave desert could generate 7GW of renewable solar powercould

Email, RSS Follow

According to a study conducted by ICF, a consulting firm for the US Department of Defense, surplus land at four military bases in the Mojave desert in California could be capable of producing up to 7 Gigawatts of solar power. These bases include, the Edwards Air Force base, Fort Erwin, China Lake and Twenty-nine Palms. Some 37,873 acres of land is available for setting these solar power plants, without impacting the space needs of the military for its ongoing operational needs or for potential future needs. The type of solar power plant to be installed, whether silicon flat panels or solar concentrators, has not yet been determined. If the go-ahead happens, power plant construction could commence by 2015.

Germany Installs More Solar Panels in December 2011 Than US Did All Year

Some more astonishing stats on the progress Germany is making on solar power thanks to good, steady and predictable renewable energy policy: Greentech Media shares the astonishing fact that in the month of December alone Germany installed 2 GW of solar PV. For the whole of 2011, Germany installed 7 GW.

The US managed to install 1.7 GW in the same time period—which isn’t to knock US installation rates so much as to further highlight the massive Germany push to install more PV before the feed-in tariff for it drop as planned.

Is Google looking to revive the ailing planet with investments in clean energy

Email, RSS Follow

Renewable resources and non renewable resources are at two ends of a tug-of-war battle. While the latter is presently being used to an exhaustive extent, the former is still trying to find a prominent place in the list of energy sources. Conventional sources like coal have been used for a number of decades to power industries and homes. Its abundance and cheap cost is what propelled many to turn to it in the first place. The Industrial Revolution of the 18th and 19th centuries saw huge amounts of coal being used to drive countries like Britain to the forefront of progress. Earlier, this natural resource was used in small quantities and coal could be mined from close to the surface of the earth. However, as demands increased, there was a need to drill ever deeper.

China’s Solar PV Players Ramp Up Overseas Investments

Email, RSS Follow
Chinese solar photovoltaic (PV) companies aren’t waiting around for the US International Trade Commission (ITC) and Commerce Dept. to decide whether or not China has been improperly subsidizing the industry and engaging in predatory pricing in the US market – they’ve begun shifting investment overseas.

Flexible thin-film solar PV manufacturer Ascent Solar Technologies announced yesterday that China’s TFG Radiant Group is acquiring an additional 21% equity stake in the company by purchasing shares owned by Norsk Hydro Produksjon AS for $4 million. The purchase price, at about $0.50 per share, is a 19% premium to Nasdaq-listed Ascent’s $0.42 closing share price on Tuesday, and will bring TFG’s overall equity in Ascent to 41%.

India Plans Increasing Solar Power Capacity During The Next Few Years

India seems to aim higher and think bigger in terms of its solar energy: from a set goal of 20 GW, the National Solar Mission grew its prospects to 33.4 GW all around the country, according to a report by Bridge to India.

The first step is to have 14.15 GW by 2018. By then, solar energy will have its own respected place on the national grid and more progress will have been made regarding the emissions level.

This will be possible due to the increased production of PV cells and the possibility of cheap imports from China. The final cost is estimated at around 40% less than what it is now.
