Jeff McIntire-Strasburg has been blogging a greener world via sustainablog since 2003!
Mathias studies Energy and Environmental Engineering. In his spare time he writes about solar panels and other renewable energy technologies at Energy Informative.
Most of today`s solar cells are based on silicon with extremely high purity, which is one of the major reasons why solar power is expensive. IBM has successfully created a new prototype of a solar cell that uses natural and abundant materials – copper, zinc and tin – to convert photons into electricity.
It didn`t take longer than half an hour from opening before Colorado-based Xcel Energy had to close their Solar Rewards Community program for new applications.
One of the biggest setbacks for people looking to invest in solar is a lack of a suitable place to put the solar panels. In the last few years this has been changing: community-owned solar enables households that otherwise wouldn’t be eligible for solar panels in the past to invest in, and make use of, this technology.
