Posts Tagged ‘First Solar’

This is a good overview of the solar industry by Michelle Bennett of The article discusses Nanosolar‘s thin solar cell technology, traditional polysilicon photovoltaics, AVASolar’s CdTe thin film technology, problems with ramping up production of new (and old) PV technology, and alternative clean energy techniques, including solar heating. The article doesn’t mention First Solar, who are in production with thin film, non-silicon based photovoltaics that are, I believe, also based on CdTe (I learned about First Solar from Steve B.). However, it is a nice summary of the solar panel, photovoltaic (or PV) industry. Ms. Bennett mentions that Nanosolar has beaten the $1/Watt goal according to the US Department of Energy (DOE), so their solar panels are officially generating electricity cheaper than coal.

The story does omit mention of the terrible environmental problems in China due to polycrystalline silicon production.

In Ms. Bennett’s article, the point is made that with oil falling out of favor, a potential opportunity for coal exists to compete with solar, etc. Luckily, as I’ve blogged about, some investment banks are refusing to fund coal-fired electricity plants. We need to make sure that our government plays its part in keeping coal from expanding (which is a realistic goal after the current administration is swept out). Coal plant emissions have already been ruled illegal in the US.* A great example is being set by Germany, for example, where solar and wind power are being pursued aggressively. Spain is also very active in solar power, and England is pursuing wind power with vigor.

Thanks to cmanders53 for DIGGing this article, which is how I came across it.

*On Friday, a US federal appeals court in Washington ruled that a policy by the Bush administration that exempted coal- and oil-fired power plants from regulations on emissions of mercury and other hazardous substances “was unlawful”. See the link above for more by Sam Carana on illegal coal emissions.
