Expatriate Australian solar power company Ausra was one of the companies that featured heavily in my post on concentrating solar thermal power earlier in the year. California Governor Arnold Schwarzenegger has opened Ausra's first plant, a 5 MW plant at Kimberlina in central California (the first to open in 20 years) which will generate enough electricity during peak hours to power 3,500 homes. Ausra's next plant will be a 177 MW plant nearby in San Luis Obispo County. The SMH quoted Schwarzenegger as saying "This next generation solar power plant is further evidence that reliable, renewable and pollution-free technology is here to stay, and it will lead to more California homes and businesses powered by sunshine. Not only will this large-scale solar facility generate power to help us meet our renewable energy goals, it will also generate new jobs as California continues to pioneer clean-tech industry".

A former NASA scientist has used radio waves to transmit solar power a distance of 92 miles (148 km) between two Hawaiian islands, an achievement that he says proves the technology exists to beam solar power from satellites back to Earth. John C. Mankins demonstrated the solar power transmission for the Discovery Channel, which paid for the four month experiment and will broadcast the results Friday at 9 p.m. EDT. His vision is to transmit solar power collected by orbiting satellites as large as 1,102 pounds (500 kg) to lake-sized receiver stations on Earth.

Energy Matters has a post on a new solar PV farm in Portugal - Portugal's Largest Solar Farm Opens. Portugal's Acciona Energy recently opened the country's largest solar power farm, executing the construction of the project in a record time of 13 months. The solar farm covers an area of 250 hectares in the municipality of Moura (Alentejo region), near the border with Spain. The AUD$571 million 48 MW facility will provide power to over 30,000 Portugese households; producing 93 million kWh of electricity annually and avoiding over 89,000 tonnes of carbon dioxide emissions compared to a similar output via coal fired power generation.

The Solar Electric Power Association (SEPA) has outlined four easy steps to a thirty fold increase in the size of the US solar power industry between 2009 and 2016, leading to over $230 billion worth of investment and the creation of 440,000 permanent jobs. The influential industry group laid out the plans at this week's Solar Power International conference in San Diego. The four key recommendations to achieve this goal are as follows:

Something that has long been a dream of mine looks like it will be a reality soon. I have always wanted to see a solar powered solar panel factory, or a wind powered wind turbine factory. Basically you use a little fossil fuels to get started, then the first however many turbines/panels off the line power the factory, from then on in it's all carbon neutral.

Technology Review reports that the idea of hybrid gas-solar thermal power plants is being considered for coal fired plants now - Cutting Coal Use with Sunshine. Feeding heat from the sun into coal-fired power stations could turn out to be the cheapest way to simultaneously expand the use of solar energy and trim coal plants' oversize carbon footprints. At least that's what the Electric Power Research Institute (EPRI), a nonprofit organization backed by the electricity industry, is hoping. Last week, the institute launched a nine-month, $640,000 study to pin down the scale of the opportunity and the engineering challenges involved with making these seemingly disparate technologies work together. The study will examine the potential use of solar-thermal technology at a pair of coal-fired power stations, in New Mexico and North Carolina.

A community in Canada has an unusual form of solar power that can provide over 90% of the annual heating and hot water needs for the homes, despite being situated in a cold Alberta location where winter temperatures can reach -33 degrees C (-27 F). The Drake Landing Solar Community collects solar energy in a heat storage fluid through an array of solar panels on the roof of each home and covering all of the garages at the back of each home. The heated fluid is transferred to a neighborhood energy center, and then into the ground beneath an insulated layer, where the heat is stored in the earth.

As traditional energy sources become increasingly rare and expensive, many homeowners are turning to the skies and learning how to harness energy from the sun. Solar cell technology has been around since the 1950s, but technology has improved considerably and at current levels of efficiency it is worth taking the time and effort to consider a Solar Power Home Now Solar cells are also called photovoltaics, or PV, by the boffins. In basic terms, they are made of semi conducing materials, which, when exposed to the sun go through a distinct process. The solar energy separates the electrons from the atoms within the material and the movement of the electrons creates power, or electricity. Thus light (photons) is converted into electricity (voltage).

The solar industry is booming. With waves of investment and grants, the solar power industry is for the first time becoming a serious business. New power plants will soon be pumping power out to consumers, while other firms market to sell panels directly to the consumer, providing them with a more direct means of experiencing solar energy.

Solar Umbrella House is quite simple the most tranquil green house that one would ever come across and it is a refreshingly new sustainable house design that does not look outrageously lavish, but is simple, serene and filled with captivating magic of solar power. I have always believed that simple stuff with sheer elegance are bigger winners compared to designs filled with pompous glitz that shout out loud. The Solar Umbrella Home is a house that is completely powered and lit by the energy of the sun. In this case when I say completely, I mean the whole 100% and nothing less at all!

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

Spiegel Online published a series of pictures titled "Desertec: Strom aus der Wüste" (translation: Desertech: Electricity from the desert). It includes this image of how much land would be needed to power the world, Europe or Germany with solar-thermal power. The idea is similar to a post we did a year ago: How Much Land to Power The Whole World with Solar?

Jamais Cascio has a post on the widespread availability of DIY solar panels in the US - Living in the Green Future. Popped into Costco today to pick up a couple of items, and what did I see? Just in case you can't read that too well, it's a 60W solar panel setup, with inverter (allowing it to power 110V devices), junction box to hook the four panels together, cabling, and frame... for under $300. Stacked like tires at Costco. This is a beautiful example of why I talk about the banality of the future. Cheap solar power systems readily available to the unwashed masses was once something out of science fiction; today, it barely elicits a glance from shoppers stocking up on cases of pickles and TVs by the six-pack.

New South Wales, Australia is the site of a pilot project where solar thermal technology reduces the use of fossil fuels. Coal and solar generate electricity using the same turbines. Coal power plants can utilize solar to produce 15%-60% of the electricity. A higher quantity is possible, but requires significantly more modifications to be made to the coal boilers.

Wandering through the Maker Fair expo, I came across this solar charger I hadn't heard of before. It's called GoBe, and looks like a great portable way to charge up some hefty devices, possibly even your laptop. It comes in two parts - a brief case-sized fold-out solar panel that can be propped up at different angles, and a lantern-sized battery pack. The solar panel has a max of 13 watts, which means you'll get back-up power to a laptop after a day's worth of charging, but can't really run a laptop off of it. However, it's great for charging up the GoBe hub so you have spare power for a wide range of other devices.

The solar power installation at Applied Materials' headquarters is further evidence that companies looking to go green should think blacktop. The Sunnyvale, Calif.-based maker of gear for making high-tech products announced Friday that it has completed the installation a pair of solar power systems that together can produce 2.1 megawatts of energy--which qualifies it, the company says, as the "largest solar power deployment at a corporate facility in the United States."

- U.S. producers of solar power will no longer need federal subsidies within eight years because by then solar power will cost less than electricity generated by conventional power plants, industry players said this week. The U.S. government recently extended tax breaks for wind and solar producers for another eight years. They are set to expire in 2016.

Welcome to the do it yourself guide to transform your home to a Solar Powered Home, a Wind Powered Home or a combination of both. The first thing you need to know is although solar and wind energy are free and clean they are not free to get. With this guide though you will be able to make it economic to switch to solar or wind power.

Large-scale solar power is beginning to take on the job of meeting the demands made by California's air conditioners for electricity. Pacific Gas & Electric and Brightsource Energy today announced they have expanded a series of solar power contracts for a total of 1,310 megawatts of electricity - enough to power 530,000 California homes during peak hours with energy from the Sun. Completion of the first project will nearly double the amount of solar thermal electricity produced in the United States.
