The speed of the solar revolution is mindboggling! When we met at climate talks in Copenhagen in 2009 we were all desperate. Many went home crying. We had failed to address the threat of global warming. What noone even hinted at was that the price of solar energy would fall 90% in the years after. This is what is driving the green transition now - the scale and speed and flexibility of solar energy. Added price of wind energy has fallen nearly as much. Price of battery storage is sky diving. Water batteries is a great alternative. Solar is meaningful as two panels at the roof of a hut, providing  reading light for children. Or as mega plants like in China and India, bringing gigawatts of clean energy, the scale more like the ocean. The is no doubt - solar is the energy of the 21st century.
