It is highly recommended that turbine OEM's consider thermostatically controlled heater elements for their florescent lighting fixtures as a standard item when considering their lighting systems for use in extreme cold climate applications.
The U.S. approved three renewable-energy projects to be built on federal land in California and Nevada. The two solar farms and one wind project are expected to total 1,100 megawatts of capacity, enough to power more than 340,000 homes, Interior Secretary Ken Salazar said today at a press conference in San Francisco. The U.S. doubled its use of renewable-energy during the past four years and these projects are part of the Obama administration’s strategy of promoting wider use of solar, wind and geothermal energy on federal lands, he said. The solar farms are in one of 17 zones approved by the Interior Department last year to accelerate the approval process. “They are the blueprint, the bible, if you will, of where solar energy will go on public lands in the years ahead,”Salazar said. The 750-megawatt McCoy Solar Energy Project, owned byNextEra Energy Inc. (NEE), and Electricite de France SA’s 150-megawatt Desert Harvest plant will use photovoltaic technology and are in Riverside County, in Southern California. Duke Energy Corp. (DUK)’s 200-megawatt Searchlight Wind Energy Project is in Clark County, Nevada. Edison International (EIX)’s Southern California Edison utility received approval from state regulators last year to buy power under a 20-year contract from McCoy’s first 250-megawatt phase, which is expected to start producing power in late 2016. EDF and Duke haven’t announced power-purchase agreements and none of the three companies have named suppliers.
China-based Suntech Power Holdings Co Ltd said it would close its only solar panel-making plant in the United States to cut costs, two years after opening the facility that never reached full production. Shares of the company, struggling to cover a convertible bond due this Friday, fell 9 percent to $1.05, their lowest in more than two months. Suntech opened the plant in Goodyear, Arizona in September 2010, saying that making panels in the United States would reduce time, costs and greenhouse gas emissions related to sourcing panels from overseas. The plant, however, has been weighed down by U.S. import tariffs on solar cells and aluminum frames as well as a global panel oversupply. Suntech is required to pay duties of 35.97 percent on solar cells imported from China and used in the plant, the company said on Tuesday. The plant, originally expected to scale up to 120 megawatts (MW) per year, was scaled down to 15 MW in November. The closure, slated for April 3, will affect 43 employees, the company said. Suntech had 17,693 employees as of December 2011, the latest period for which job data is available.
The solar energy business is growing quickly, but future growth will not include oil giant BP. At the IHS CERAWeek energy conference in Houston, BP's CEO made it clear the company is done with solar. "We have thrown in the towel on solar," Bob Dudley said after delivering a wide-ranging speech Wednesday. "Not that solar energy isn't a viable energy source, but we worked at it for 35 years, and we really never made money," he added. BP, which announced it was winding down its solar business last year, says it is still committed to other renewable resources, such as wind power and biofuels production. But the move away from solar is especially striking considering BP's recent history. In 2000, the company changed its logo to resemble the sun and made a big deal of its "beyond petroleum" campaign. BP's exit from solar has more to do with a changing business than lack of will. "The solar industry BP was involved in 10 years ago has very few similarities to the solar industry today," says Finlay Colville, vice president of the research firm NPD Solarbuzz. Colville says BP was one of the early companies in the solar business. Back then, the market was based on a different model — one more focused on research and development. He says now the business is all about efficient production and low prices, something more suited to the Asian companies taking a lead role in the solar panel-manufacturing business; so BP's exit from solar doesn't mean the industry overall is in trouble.
In recent years, the balance usually tips in China's favor when it comes to trade with the United States. But according to a new study there's at least one sector in which America is starting to have the upper hand: clean energy. The United States exported more clean energy products to China in 2011 than it imported, according to a report released Wednesday by the Pew Charitable Trusts, ultimately amounting to a $1.63 billion trade surplus in solar and wind power equipment among other products. About $8.5 billion worth of clean energy goods and services shuttled between the world's two largest economies in 2011, according to Pew. While that's just a sliver of the half a trillion dollars' worth of goods and services traded between China and the United States, the U.S. surplus in the clean energy sector challenges widely held views that China is becoming the world's foremost supplier.
A first-of-its-kind requirement for solar power systems is going to be implemented in Lancaster, California. The requirement is that solar power systems be installed on all new single-family homes within the city. Furthermore, this announcement comes from a Republican mayor. All newly-built single-family homes within Lancaster will be required to feature solar power systems starting on January 1, 2014. This is a rather stunning announcement in itself, but the fact that it comes from a Republican is even more surprising. Mayor Rex Parris is a big solar power advocate, though. You may have heard of him already, as he has previously stated his intention to make Lancaster “the solar energy capital of the world.” The new requirements “will be written into Lancaster’s ‘Residential Zones Update’ on residential solar,” Greentech Media reports. In addition to a variety of new requirements having to do with energy efficiency and green building practices, new single family homes will have to meet minimum solar energy system requirements.
Alta Devices today disclosed that it has reached 30.8% solar cell efficiency. This new NREL (National Renewable Energy Laboratory) verified record has resulted from the company's first implementation of a new generation "dual junction" solar cell technology which augments the company's "single junction" technology. Higher efficiency directly translates into more electricity generated from smaller surface areas. Therefore, applying Alta's highly efficient, very thin and flexible mobile power technology to consumer devices can extend the battery life of everyday products such as smartphones, tablets, keyboards, mice, remote controls, and more. "We are changing the way solar technology is used," said Chris Norris, president and CEO of Alta Devices. "With our technology, enough energy can be generated from sunlight to effectively power devices in ways not previously possible. We are working with a number of customers who are designing their mobile products to increase battery life; and in some cases, we can provide enough energy to eliminate the need to plug into the electric grid."
The continued accumulation of solar project portfolios drove much of the M&A activity in 2012, as transaction activity was strongest among targets categorized as producers of solar energy and EPC integrators/developers.
As a result, of being in this higher risk environment we have to think defensively and make sure to protect some of these incredible profits.
I live in the middle of the woods out in the country in Ohio; far enough out where there is no cable service, no gas, no piped-in water, no sewers, cell phones don't work, the grid provides reasonable power most of the time, and the one analog-POTs telephone line works if there is not too much water in the crick.
Many homeowners want security and protection in case the grid goes down, and battery backup systems are a great solution to bring this peace of mind.
In Part 1 we examined the energy bank, and the loads upon it. Next, we will explore some of the energy harvesting needs and capabilities.
