via internet science tech Despite the launch of the World's largest solar park on a former open-pit mine, it's been a little hard to track the health of Germany's solar sector of late. Given its status as a world leader in solar capacity due to generous feed-in tariff subsidies, there was justifiable concern as planned cuts to the tariff coincided with increased competition from Chinese suppliers and a slump in demand. But Renewable Energy World reports t... Read the full story on TreeHugger

There are two ways to lower the cost of producing energy through photovoltaics – more efficient solar cells (more power per square foot) and lower production costs (lower cost per square foot). The ETAlab of the Fraunhofer ISE has devised a way to do both simultaneously. The research team in the laboratory for new solar cell structures and processing steps has not only made the solar cell contacts out of 100% cost-effective materials (replacing expensive silver with cheaper copper and nickel), but the process also increases the efficiency of the solar cell to a very respectable 21.4%.

In order to achieve a high level of efficiency, the front contacts in the solar cell not only have to exhibit a low level of loss with light-generated current but also cover the least amount of the cell surface possible. Technologically speaking, materials ...

wind turbines in germany photo photo: Jason/CC BY-ND Germany's strong push in renewable energy over recent years is paying off. According to Der Spiegel (via Mongabay), Germany now produces 20.8% of its electricity from renewable sources. That's an increase of 15 percentage points since 2000, with an an increas...

The price of solar is dropping fast, opening new opportunities for community-scale renewable energy across the country.  But despite the improving economics and tremendously sunnier skies, the United States lags far behind Germany in installing new solar power.

The biggest difference is policy. The U.S. has two major federal incentives (a 30% tax credit and accelerated depreciation) for solar power, and a few state programs for solar power. Germany and most other developed countries use a feed-in tariff for renewable energy, a policy responsible for three-quarters of the world’s solar power capacity.

What might happen if the U.S. adopted Germany’s flagship “feed-in tariff” policy, responsible for 10 gigawatts of solar in just two years? Let’s take a look at how such a program would be priced.

First, we’re marketing-conscious in America, so we’ll call it something better, like a CLEAN contract, for Clean Local Energy Accessible Now.

Then we’ll need to adjust the ...

SCHOTT Solar announced the world’s first monocrystalline screen-printed solar cell on Wednesday — with conversion efficiency of 20.2%. The Fraunhofer ISE in Freiburg, another research institute, confirmed the results of SCHOTT Solar’s tests with an independent measurement.

The previous record – 17.6% – was achieved through use of multicrystalline solar cells, one of several methods of making a solar cell go. SCHOTT Solar’s Dr. Axel Metz, head of solar cell research and development at SCHOTT Solar, acknowledges the multicrystalline concept as the greatest contributing factor to his team’s outstanding results. “We’ve been concentrating on the development of monocrystalline cells since the start of 2011,” he said. “We had three years of experience with the multicrystalline cells to carry over to the monocrystalline concept.”

The initial attempts produced cell efficiency of well above 19%, but that wasn’t quite good enough. ...

A serialized version of ILSR‘s new report, Democratizing the Electricity System, Part 1 of 5.

The 20th century of electricity generation was characterized by ever larger and more distant central power plants.  But a 21st century technological dynamic offers the possibility of a dramatically different electricity future: millions of widely dispersed renewable energy plants and storage systems tied into a smart grid.  It’s a more democratic and participatory paradigm, with homes and businesses and communities becoming energy producers as well as consumers actively involved in designing the rules for the new electricity system.

Several decades ago, several people – Amory Lovins in Brittle Power, David Morris in Self-Reliant Cities – explored the implications of this decentralized vision.  Most importantly, this vision represents a transformation in the ownership and control of the electricity system.  Instead of ...

via internet business politics It's been a little hard to follow the state of German renewables of late. We've already seen massive growth of renewable energy due to aggressive feed-in tariffs, and even arguments from within the Government that the country should go 100% renewable by 2050. But, despite its high profile commitment to phase out nuclear power (a... Read the full story on TreeHugger

[28 Jun 2011 | Comments Off | ]
Despite recent safety concerns in the wake of the Fukushima crisis, French President Nicolas Sarkozy pledged to invest 1 billion euros in the next generation of nuclear power generation. Saying that a moratorium on nuclear production “makes no sense,” Sarkozy said France will focus investment on “fourth-generation” technology, as well as research into nuclear safety. France, which generates about 74 percent of its electricity from its 58 nuclear reactors, is also the world’s biggest net exporter of electricity from nuclear sources. “There is no alternative to nuclear energy today,” Sarkozy told reporters. The commitment comes as neighboring Germany moves to phase out all of its nuclear reactors by 2022. Sarkozy also pledged investment of another 1.3 billion euros in renewable energy production. Other nations are also lining up to build nuclear reactors despite the Fukushima crisis, including the United Arab ...

In an interesting marriage of clean and dirty tech, Deutsche Welle is reporting that the state government of Lower Saxony in Germany is looking into repurposing old abandoned coal mines inside the Harz mountains as pumped storage for wind power.

The idea has attracted approval not only from environmentalists in the region, who like the invisibility of the storage, but also from former coal miners, who like the idea of the disused coal mines being put to good use as a kind of “green battery” for wind power.

“The tradition of mining is so great in the Harz region, that they want to see the mines back in use again, so there are practically no critics of the project,” noted Marko Schmidt, an engineer for Lower Saxony’s Energy Research Center, who came up with the concept.

This acceptance is surprising to ...

Solar photovoltaic panels on home in Germany, one of many now featuring solar PV panels.

There’s a nice little statistic for you. Germany Trade & Invest (GT&I) recently reported that its latest figures show Germany’s solar photovoltaic (PV) industry employs over 100,000 ‘green’ workers now, more than the US steel industry. Here’s a little more from PV-Tech: The main requirement for ‘Made in Germany’ components is driven by the country’s domestic solar market, which installed a total of 7.4GWp in 2010. Yet Germany is also a manufacturing platform for other European PV markets, including Italy, where the feed-in tariff adjustments stipulate that installed technology must be ‘Made in Europe’. At present, approximately 75% of European solar cells, modules and other BOS are currently made in Germany. More Germany stories on CleanTechnica: Germany: Talk of the ...
