Cheapest Way to Get Hydrogen: the Photoelectrochemical Diode | Free Energy | The Green Optimistic
Penn State researchers have found a cheaper method of producing hydrogen from water by the same old effect of electrolysis aided by the Sun’s rays. They do not use classic solar cells, because these are expensive, but made a nanotechnology-based solar cell, called photoelectrochemical diode, that is simplistically said on the bottom of the water holding recipe.

Dying to Boost Solar Efficiency by 50% : CleanTechnica
The most efficient form of solar technology today is (arguably) extreme concentrated photovoltaics, essentially solar panels placed under a magnifying glass, but the problem with these systems is heat. Concentrated sunlight can melt silicon solar panels unless you include specialized cooling systems. Cooling technology costs money, and the panels require expensive tracking mechanisms to follow the sun through the day. MIT’s new solar system bypasses the heat and traching problems all together.

MIT makes solar power from windows
An exciting piece of solar research from MIT was published today in Science. Researchers at the university have created a new way to harness solar power that should hopefully reduce the cost of installations massively by using normal windows as solar generators.

90% Of Israeli Homes Have Solar Water Heaters | MetaEfficient
I recently noted that Hawaii has enacted a law that requires all new homes to install solar water heaters. Eventually, Hawaii may have as many water heaters as Israel, where 90% of homes have solar water heaters installed. When viewed from above, the Jerusalem often glitters with the shine of the thousands of solar heaters that adorn rooftops.

Solar Water Heaters Now Mandatory In Hawaii | MetaEfficient
Hawaii has become the first state to require solar water heaters in new homes. The bill was signed into law by Governor Linda Lingle, a Republican. It requires the energy-saving systems in homes starting in 2010. It prohibits issuing building permits for single-family homes that do not have solar water heaters. Hawaii relies on imported fossil fuels more than any other state, with about 90 percent of its energy sources coming from foreign countries, according to state data.

WattHead: What Do We Want? Cheap, Abundant Solar! When Do We Want It? Now!
The solar industry is booming, ramping up production capacity and driving costs down steadily towards the mythical "Grid Parity" point - the price point when solar on your roof beats paying your utility bill. That's a game changer and the solar industry is steadily heading that direction.

Solar comes out of the shadows - People's Daily Online
The tipping point at which the world's cleanest, most renewable resource is cost-competitive with other sources of energy on electricity grids could happen within two to five years in some US regions and countries if the price of fossil fuels continues to rise at its current pace, they add.

Evaluating the Cleanliness of Solar Photovoltaics Can Be Complicated : CleanTechnica
Solar photovoltaic (PV) cells are a popular and often discussed (see, for example Atlantic City Convention Center Plans Largest Solar Roof in U.S., 10% of U.S. Electricity From Solar by 2025, SF Passes Largest City Solar Program in U.S. (Finally), all of which were published within the past week) form of “renewable” or “green” energy, but a casual scratching of the surface knowledge that many people have about the technology reveals some troubling details.

10% of U.S. Electricity From Solar by 2025 : CleanTechnica
The Utility Solar Assessment Study produced by Clean Edge and Co-op America finds that solar energy is already reaching cost parity with conventional sources in some areas of the U.S. where electric rates are highest. By 2015, this will be achieved in many more areas, including Boston, San Diego, and New York. By 2025, cost parity will be achieved throughout the U.S.
