I loved seeing this chart of the mix of power supply in the UK. Coal is being edged out.
Every year, fossil fuel emissions kill millions of people – the estimate from a recent paper for 2012 was >10 million. Coal is, by a distance, the worst offender.
In the first decade of the twenty first century, investments in alternative sources were talked about in the context of being “the right thing to do.” The trouble with that narrative is that it only works with a few early adopters.
For mainstream adoption, we need it to become the obvious thing to do. We need it to be 10x cheaper and better. Even with all its negative externalities, Coal didn’t have many viable alternatives even ten years ago.
That has changed. We have an exciting couple of decades ahead of us.
