A Polysilicon shortage probably is causing problems for the solar panel industry. Producers of solar panels expect high costs and lower margins due to an unexpected shortage of raw materials.
Last months, the price of pure metallurgical silicon, the most important raw material for solar cells, rose by 35%. According to news agency Bloomberg, the price rose after officials in China closed several factories. Read More

The City of Los Angeles took a significant step toward realizing its global leadership potential. Mayor Garcetti released LA’s first-ever urban sustainability plan: the pLAn.
LA City Council members Paul Krekorian and Mike Bonin coauthored legislation for a fast route to 100% renewables for LA. With an appreciative nod from the Sierra Club, the news reported at 11district.comfollows:
“LADWP is on the verge of making significant investments in its infrastructure, and with that 100-year-old power system in need of significant upgrades, the city has an opportunity to re-create its utility in a way that recognizes the potential for a fossil-free future, demonstrates global leadership in its commitment to clean energy, and protects ratepayers from the increasing costs of carbon-based fuels.”
Under the current plan, emissions are expected to drop. Under a new plan, they could drop to zero!
The silicon cells can be re-cycled as raw material for new solar cells
For silicon PV modules, the recycling process consists of multiple steps.
ReMedia (Milano) is an Italian consortium that handles Waste Electrical and Electronic Equipment (WEEE) as well as end-of-life batteries and accumulators. Read More
Stacked solar cells could achieve more than 50 percent efficiency and 5 cent per kilowatt hour costs in 3 to 5 years. Semprius has come up with three key innovations for cheaper solar power.
Still the batteries – as far as we know, based on chemical reactions – need innovations quickly to take advantage of this great new technology.
Solar road: A nationwide system could produce more clean renewable energy than a country uses as a whole
Imagine this … Would you like to drive your electric car on roads that don’t have potholes, don’t need re-construction every year, roads that will ‘self clean’ snow or ice on them in the winter, and have illuminated lines that you can see? Solar roadways will be able to accomplish all of this with existing technology.
