Renewable energy capacity has now passed nuclear energy capacity. Europe has been leading the effort by providing a market for clean energy by way of energy policies. Germany has been the leader in Europe. China has passed the US in renewable energy capacity and it is making big investments which has given it a large internal market, particularly for solar panels. Its large internal market has cut manufacturing costs and it is the largest exporter of solar panels which have fallen rapidly in price. Italy, because of its climate, is now cost competitive using solar panels with fossil fuels for electricity generation.
It looks as though this huge market opportunity will bypass the US. Opposition from the GOP, which is totally committed to fossil fuels, will block any efforts in the US to become competitive.
