Solar Photovoltaic panel prices have fallen 75% from where they were just four years ago. In giant swaths of the world solar is the cheapest form of new energy, cheaper than coal & natural gas. This is the most important graph of this century: http://fund-balance.com/wp-content/uploads/2014/04/Solar-Module-Costs-Q1-2014.png http://fund-balance.com/wp-content/uploads/2014/04/Solar-Mod... It was made in 2012 when solar costs were $1 per watt. The Chinese solar industry has gotten the price down below .50 per watt this year. Solar PV panels are going beyond grid parity. 70% of the power generated by a coal plant is wasted in the transmission line before it reaches your home. The data has spoken and solar has won. I believe this is the development that will let us avoid run away catastrophic warming. Humans are rational actors when presented with cost-based options. Politics, biases and ideology fall away when looking at price. And ramping up and scaling production of high demand items and bringing cost down in the process is where modern capitalism shines ie. the relentless deflation in consumer technology (pcs, tablets, flat panel displays) In order to avoid catastrophic warming we have to reduce emissions by something like 80% by 2050. That seemed a pipe dream before cheap solar panels, now it feels inevitable to me. Cheap solar is the energy miracle Bill has been waiting for. I hope that he includes it in his 2015 post when solar is $.25-.40 per watt.
