Solar economy

At the Los Angeles Permaculture meeting this week, I caught up with Ben Clayton of Watts Up  America. 

He told me about their mission to bring solar PV electricity to low-income families, both here in California and in places of need around the world. 

A recurring message at the PV Summit

is the extraordinary growth projected for the solar photovoltaic field for the next 10 years.

Because of the need for energy sources that reduce greenhouse gas emissions and have predictable costs over the long term, solar energy is getting the starring role. At least 50% annual growth is projected for world solar PV cell production for at least 10 years. Beyond that, one can only guess, but the German Advisory Council projects that by the year 2100 most of all worldwide energy (70%) will come from solar.
