BrightSource Energy on Wednesday shelved a major solar power project in California for the second time this year. In a document filed with the California Energy Commission, BrightSource said it "has determined there is a need to suspend" its application to permit the 500 megawatt Hidden Hills solar thermal power project until further notice. The company did not give a reason for the suspension, and company officials were not immediately available for comment. BrightSource, based in Oakland, said it will continue to evaluate the project, which was to be located in Inyo County near the Nevada border. In January, BrightSource suspended its 500 MW Rio Mesa project in Riverside County, California after multiple delays in the permitting process. Late last year, CEC staff said the Hidden Hills project would have "significant" impact on the environment, adding that the use of photovoltaic solar panels "would be environmentally superior" to BrightSource's solar thermal technology. BrightSource disputed those claims at recent hearings, and the CEC was expected to issue a final decision on the project later this year.
Saudi Arabia wants to spend over $100 billion to build vast solar arrays and reduce its dependency on oil to generate electricity. But desert sandstorms pose a major challenge to keeping solar panels clean and efficient. Japanese startup Miraikikai is developing a solution to getting rid of this pesky dust and grit: a cleaning robot that doesn't need water. The firm has produced the Wall Walker wall and ceiling robot, and recently unveiled a prototype solar panel cleaner built with researchers at Kagawa University. It weighs about 24 pounds -- light enough to be carried by one person -- and measures about 22 inches across. It cleans with a rotating brush and can operate for up to two hours on a battery charge. The robot's efficacy has been demonstrated in arid regions, Miraikikai said in a release, and the machine can clean panels as well as human workers. Making optimal use of the device would result in low-cost cleaning even in areas with relatively cheap labor costs.
It takes more than perfunctory "safety moment" sharing and hard hat stickers to ensure employees and contractors make safety their top priority. In creating a viable safety culture, site leaders first identified the unique strengths of each company and exchanged lessons learned at other power generation facilities.
Series of reforms being explored as China seeks to expand clean tech investment
Until now Rogowski coils have delivered at best a 2% positioning error. With this improvement, the error due to the positioning of the conductor is specified at a maximum of 0.65% of the measured value for a 15mm diameter conductor irrespective of where it is positioned, even if it is adjacent to the coil clasp.
At the current time the market is overbought at a level which historically results in a pullback in the market closer to the 50 day moving average. As a result of this I have been setting our stop loss points very conservatively in order to make you that when a correction or pullback comes we will still lock in healthy profits.
Coatings are the first preventative measure for all of these assets. Since most are being deployed in desert areas or mountainous areas or along the coasts, or sometimes in the water, choosing the right coating is imperative to achieve design life.
The study investigated the current and future direction of the market and the opportunities smart grid represents for participants in the value chain.
A single dead eagle could spell trouble for a White Pine County wind farm that sells power to NV Energy. The U.S. Fish and Wildlife Service is conducting an investigation after a golden eagle was killed in late February at the Spring Valley Wind Farm, about 300 miles north of Las Vegas. San Francisco-based Pattern Energy, which owns the 152-megawatt wind energy project, reported the dead bird and turned it over to federal authorities within 36 hours of its discovery. “They did all the things they were supposed to because of an eagle death,” said Jeannie Stafford, spokeswoman for the Fish and Wildlife Service in Nevada. Even so, the wind farm could face a fine of up to $200,000 because it does not hold a federal “take” permit that would allow the incidental death of a golden or bald eagle. Stafford said the matter is under investigation by the service’s Office of Law Enforcement.
Here's how Mosaic works: Investors contribute a minimum of $25 to a project. Over the next 5 to 10 years—depending on the project—the investors will make that money back, plus interest. The return on the investment ranges from 4.5 to 6.4 percent annually, depending on the project. They can support projects in any state, but right now only accredited investors and people in New York and California can invest in the projects, due to regulatory barriers in other states. In order to qualify, projects must be for organizations that are financially stable, have adequate insurance, and benefit the wider community in some way. Recent projects include affordable housing projects, a convention center, several nonprofits, a grocery store, and a Native American reservation. Mosaic's founders want to do for solar energy what Kickstarter has done for bands and independent films, or what Kiva has done for upstart projects in the developing world. But Mosaic's model goes beyond most other crowdsourcing sites, by not only allowing supporters to invest in the solar project but also make a profit doing so.
Foxconn has announced plans to build a solar power network in China encompassing new factories and plants. According to a statement released by the Chinese Ministry of Commerce, the Taiwanese electronics manufacturer is investing in one research center, five solar-power components factories, and 20 solar-power generating plants in the southern province of Guangxi. Foxconn since 2012 has been shifting its focus toward solar power, pouring nearly 100 billion yuan (US$16 million) in other provinces in China, where the government has provided solar manufacturers with heavy subsidies. In the face of competition, increasing labor cost and pressure from business customers, Foxconn's cellphone subsidiary company had failed to meet market expectation and reported an annual loss of US$316 million in its fiscal 2012. Hence, to some, the moves could be seen as part of a strategic plan. Despite last week bankruptcy filing of SunTech, China's biggest solar panel manufacturer, the outlook for the domestic market remains encouraging, according to Shen Hongwen, an analyst from CIConsulting company. Foxconn should be able to tap the expanding Chinese market by utilizing its financing power and management expertise, Shen said.
How much energy can we use from the sun's rays? Apparently, we can utilize far more than previously thought. A new study shows that the energy limit is far higher than first believed. The new study, described in the journal Nature Photonics , studied how to develop and improve the quality of nanowire crystals. These nanowires possess a cylindrical structure and a diameter that's about 10,000 part of a human hair. They hold enormous potential for the development of solar cells and the future of quantum computers and other electronic products. So how do these nanowires work? They naturally concentrate the sun's rays into a very small area in the crystal that they possess by up to a factor of 15. Due to the tiny nature of the wire's diameter, the crystal can cause resonances in the intensity of light in and around nanowires. These resonances can concentrate the sunlight and convert it into energy, essentially giving a higher conversion efficiency of the sun's light. Previously, scientists thought that the efficiency limit of sunlight was far lower. Known as the "Shockley Queisser Limit," it was held as a landmark for solar cell efficiency for many years. Yet with the discovery and development of these nanowires, it seems that the limit is far higher than previously thought.
Scientists at Stanford University have improved the efficiency of a revolutionary solar cell by around 100 times. Unlike standard photovoltaic cells, which only capture light energy, Stanford’s new device captures both light and heat, potentially boosting solar cell efficiency towards 60% — way beyond the 30-40% limit of traditional silicon photovoltaic solar cells. This new device uses a process called photon-enhanced thermionic emission (PETE). In photovoltaic cells, photons strike a semiconductor (usually silicon), creating electricity by knocking electrons loose from their parent atoms. The PETE process is similar, but also very different and altogether rather complex. In essence, think of it as the photovoltaic equivalent of a turbocharger. Full Article.
Suntech, one of the world's biggest solar panel manufacturers, has defaulted on a $541m (£358m) bond payment in the latest sign of the financial squeeze on the struggling global solar industry. Suntech Power Holdings' announcement was a severe setback for a company lauded by China's Communist government as a leader of efforts to make the country a centre of the renewable energy industry. Its founder, Shi Zhengrong, became one of the industry's most prominent entrepreneurs and a billionaire, only to see most of his fortune evaporate as the company's share price plummeted. The company is "exploring strategic alternatives with lenders and potential investors," David King, who replaced Shi as a CEO last year, said in a statement. Suntech was due to make a $541m bond payment on Friday but ran short of cash following heavy losses over the past year.
