I’m concerned about cutting UK emissions of twaddle – twaddle about
sustainable energy. Everyone says getting off fossil fuels is important, and
we’re all encouraged to “make a difference,” but many of the things that
allegedly make a difference don’t add up.
Twaddle emissions are high at the moment because people get emotional
(for example about wind farms or nuclear power) and no-one talks
about numbers. Or if they do mention numbers, they select them to sound
big, to make an impression, and to score points in arguments, rather than
to aid thoughtful discussion.
This is a straight-talking book about the numbers. The aim is to guide
the reader around the claptrap to actions that really make a difference and
to policies that add up.
I didn’t write this book to make money. I wrote it because sustainable en-
ergy is important. If you would like to have the book for free for your own
