Google has abandoned its effort to come up with better flat mirrors and power plant designs for producing electricity from the sun’s heat, but it is releasing its research results so that others could perhaps use it to create commercially viable solutions.

It’s interesting to see what Google thought it could contribute to the field of solar thermal power plant engineering. The company’s research has focused on using smaller engines and light-weight mirrors with better controlling software — along with a tower outfitted with equipment to receive the concentrated sunlight and run a turbine and generator — to produce electricity. It ran into some technical challenges with engineering a suitable power tower before it decided to shelve the research project.

Google Makes a Mistake

As you can see from the linked stories on the left of this article, Google is quite a big proponent of renewable energy. They have made all kinds of investments in wind, solar, geothermal, etc. Some are to generate clean energy for their own needs, others are more akin to financing deals to help big wind and solar farms get built. In any case, it is very commendable work and if more big corporations had the long-term vision of Google, the world would definitely be in better shape.

Google Pulls Plug on Renewable Energy Project

Google Inc has abandoned an ambitious project to make renewable energy cheaper than coal, the latest target of Chief Executive Larry Page’s moves to focus the Internet giant on fewer efforts.

Google said on Tuesday that it was pulling the plug on seven projects, including Renewable Energy Cheaper than Coal as well as a Wikipedia-like online encyclopedia service known as Knol.

The plans, which Google announced on its corporate blog, represent the third so-called “spring cleaning” announcement that Google has made since Google co-founder Page took the reins in April.

Would tariffs placed on Chinese solar panels amount to “protectionism?” Are the companies most critical of the trade complaint “just crying foul?” And what’s more important to American companies, the race to grid parity or the desire to reclaim solar manufacturing from China?

With the creation of competing coalitions, the sides have been clearly labeled, and the opinions have become increasingly entrenched. But there remains a striking lack of clarity about what happens if and when tariffs are placed on solar panels and cells imported into the U.S., and how that could ultimately impact American businesses and American solar capacity.

People understand the importance of energy conservation and therefore are gradually opting for methods in which natural and renewable resources of energy are implied for generating power. Everything inside our homes, from your cooking appliances to A/V devices to lighting fixtures, is going green these days. Have you ever considered the idea of having a green roof for your home? There are a numerous methods that can be implied on the roofs of the homes to make them green, which will not only help cut down on the electricity bills but will also make your home an eco-friendly and an eye-pleasing appearance. Let’s take a look at some of the interesting green options for your rooftop after the jump.

Nanoantennas could make for more efficient solar panels

Radio waves are a type of electromagnetic energy, and when they’re picked up by traditional metallic antennas, the electrons that are generated can be converted into an electrical current. Given that optical waves are also a type of electromagnetic energy, a team of scientists from Tel Aviv University wondered if these could also be converted into electricity, via an antenna. It turns out that they can – if the antenna is very, very short. These “nanoantennas” could replace the silicon semiconductors in special solar panels, which could harvest more energy from a wider spectrum of sunlight than is currently possible.

Nazi Bunker to Become Europe's Largest Solar Power Plant

A former Nazi bunker located in the Wilhelmsburg district of Hamburg, Germany is about to get full-scale makeover. The building, which sorta looks like a giant LEGO, is set to become Europe’s largest renewable energy power plant.

When it’s all said and done, the power plant will supply 3,000 homes with heating and 1,000 of those with electricity, cutting 6,600 tons of CO2 per year.

Come 2012, this nine story structure (called a Flaktürme in German) will boast a 110 kWh rooftop photovoltaic system and a south-facing 0.6 GWh solar-thermal unit. And the building’s interior is being reserved for even further renewable expansion. It will include both a 10.5 GWh woodchip combined heat and power plant and a 3.7 GWh biomethane plant powered by a nearby industrial plant, for example. Waste heat will also be stored. That sounds like a lot but this building could house around 80 single family homes. It is that big.

How Much Can You Really Save with Solar

I just returned from the Solar Power International (SPI) show, an annual event for the solar industry, and there were a few things I kept hearing over and over.

One was: “It’s simple: People can live better with solar.” The second was: “The price of electricity will rise over the next decade.”

Over the last 40 years, Americans have been fortunate to have largely consistent electric rates. But as utility providers need to replace aging systems and fuel costs rise, experts predict that homeowners will soon need to pay more for electricity.

Should consumers pay more for renewable energy in order to promote a certain technology? That’s an interesting question raised by California regulators on Thursday, when they approved what they acknowledged to be a pricey contract for Abengoa Solar to sell power to Pacific Gas & Electric.

The California Public Utilities Commission voted 4-1 to approve the 25-year contract, which will allow Abengoa to build the 280-megawatt solar farm called Mojave Solar in southern California. The company already has secured construction permits from state and federal regulators, as well as a $1.2 billion loan guarantee from the U.S. Department of Energy to help pay up to 80 percent of the project’s cost.

Householders who are in the process of having solar panels put on their roof have six weeks to complete the job or face seeing the predicted income they generate slashed after the government said it was cutting feed-in tariffs by 50%.

Despite pledging to be “the greenest government ever”, the Tory-led coalition last week shocked the renewables sector by announcing that only installations completed by 12 December would get the full payments they were promised. Hundreds of householders who had signed contracts to have panels fitted have now pulled out and others are expected to follow.
