Polysilicon Shortage: Production Solar panels in Danger

Polysilicon Shortage: Production Solar panels in Danger

Prices drove from $14 to $19 a kilogram

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

LA goal: 100% renewables

LA goal: 100% renewables

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.com follows:

“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!

Solar road, save and green

Solar road: A nationwide system could produce more clean renewable energy than a country uses as a whole

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.
