Samsung just threw their hat into the growing LED market by launching a new line of bulbs that can suit practically any lighting need. The line features 7 energy-sipping bulbs that should fit practically any socket in the house. The new bulbs join the ever-expanding options available to shoppers who are looking to save money and get just the right light. Read on for a closer look at these new bulbs, and to learn how they stack up against the competition.
SolarReserve has completed the central point of a solar project that uses molten salt storage to deliver power to the grid well after the sun has gone down.
The startup company today said it has completed the 540-foot tower of the Crescent Dunes Solar Energy Project near Tonopah, Nev., which is expected to start delivering 110 megawatts by the end of 2013. When it comes online, it’s projected to have 10 hours of storage, the longest full-load storage capacity for a solar plant.
Adding storage turns solar into a continuous power source and allows project developers to earn more money for their electricity. As a result, solar projects that use heat to make electricity have added molten salt storage to their facilities.

Going solar is a beautiful thing. It not only saves money on your electrical bills for decades to come—it conserve the earth’s precious resources as well. But where to turn for current, insightful resources on solar panels, pricing, financing and incentive options in 2012? How to know how much energy your home consumes right now, and how much you can save down the road with solar-powered renewable energy?
I’ve gathered eight amazing resources to get you started on the path to solar independence. Here’s how to go solar in 2012.
In a mashup of biology and electronics, researchers said they’ve made progress in making low-cost solar cell from plants.
A paper published in Scientific Reports today describes an improved method for making electricity-producing “biophotovoltaics” without the sophisticated laboratory equipment previously needed. Researchers said custom-designed chemicals could be mixed with green plants, even grass clippings, to create a photovoltaic material by harnessing photosynthesis.
Maricopa County, Arizona is set to play host to a 125 MW photovoltaic solar power plant, according to an announcement on Tuesday from Fluor Corporation. The company has won the separate contracts to build and maintain the facility, which upon completion will fleetingly join the ranks of the the world’s largest photovoltaic solar farms. The project, known as Arlington Valley Solar Energy II (AVSE II) will be built on 1.8 square miles (4.7 sq. km) near to the Arlington Valley Combined Cycle Facility, a 577 MW natural gas plant also designed and built by Fluor.
Every year the EPA releases its list of top green power purchasers in the business world. We’ve dutifully reported on them for a while now on that annual schedule, but as it so happens these stats are updated on a quarterly basis. Relaying that info that frequently probably isn’t necessary, but the latest quarterly stats, just announced, do have some changes that are particularly notable.
Advances are opening solar to the 1.3 billion people who don’t have access to grid electricity.
The falling cost of LED lighting, batteries, and solar panels, together with innovative business plans, are allowing millions of households in Africa and elsewhere to switch from crude kerosene lamps to cleaner and safer electric lighting. For many, this offers a means to charge their mobile phones, which are becoming ubiquitous in Africa, instead of having to rent a charger.
Technology advances are opening up a huge new market for solar power: the approximately 1.3 billion people around the world who don’t have access to grid electricity. Even though they are typically very poor, these people have to pay far more for lighting than people in rich countries because they use inefficient kerosene lamps. While in most parts of the world solar power typically costs far more than electricity from conventional power plants—especially when including battery costs—for some people, solar power makes economic sense because it costs half as much as lighting with kerosene.
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.
The epic voyage of the Tûranor PlanetSolar – the world’s largest solar-powered boat – will soon come to a close as the ship closes in on its final stretch. The Swiss vessel is a full-bore high-tech solar harvesting machine whose deck is covered in 537 square meters of photovoltaic panels. The array produced enough energy for the boat to navigate the entire circumference of the Earth without any other means of energy. The Tûranor PlanetSolar is currently set to depart Abu Dhabi en route to their final port in Morocco – the same place the expedition launched on September 27th, 2010. The journey has come full circle in more than one respect, as it was not too long ago the only way to navigate the earth was by harnessing renewable energy with sails.
