Thanks to significant levels of government support, wind power and solar PV have progressed in leaps and bounds over the past decade. They have now reached a scale that they represent a major component of new power supply additions in the developed world. But while these two low emission energy sources are making good progress, they aren’t enough to solve dangerous climate change.
The other near zero carbon options for meeting our energy needs are pretty much stalled or barely out of the starting blocks. Meanwhile additions of coal in China and India have been overwhelming a great deal of the progress in renewables.
