First Solar wins reprieve in toxic substance ban
The revised European Union law bans the use of six hazardous substances in electrical and electronic equipment, including cadmium, which is used by U.S.-based First Solar — the world's No. 1 solar company by market share — in its panels.
"Photovoltaic solar panels, fixed industrial machinery and military material are among equipment that will remain outside the rules," the European Parliament said in a statement following the vote.
The decision marks the latest step in an industry row over the use of cadmium telluride CdTe — which goes into First Solar's panels — as there are concerns about its eco friendliness as well as its safe disposal.
First Solar uses CdTe as a key raw material, whereas traditional solar companies, such as Germany's SolarWorld, use polysilicon. CdTe has a 10-15 percent cost advantage over the more widely used silicon, but tellurium, a tin-colored component of CdTe and a byproduct of the copper industry, is not widely available.
"Customers will now have to decide whether they want Cadmium on their roof or sustainably manufactured solar modules," SolarWorld spokesman Milan Nitzschke. First Solar said the company already has in place a return and recycling program.

EU Plans To Double Electricity Use By 2050
PARIS - The European Union is preparing an ambitious plan to completely decarbonize by 2050. Increasing the share of electricity in Europe’s energy system – electricity that will increasingly come from renewable sources - will be at the center of this strategy, the new head of the European Commission’s energy department said yesterday.
This will mean more electric cars, electric heating and electric industry. The idea is that fossil fuels should no longer be a primary energy source, heating homes, warming food or powering cars. In the medium term they should only be used to generate electricity which then powers these…
