What does a kilowatt hour look like?
Some time ago I came across a very good read by David McCay – Sustainable Energy without the Hot Air. I’ve seen many good reviews of the book, so it didn’t take me long to download and start reading it. I haven’t finished yet, but I can already confirm that the book is outstanding – it’s one of the books that fundamentally change the way you look at things around you. The only thing I knew about “kilowatt hours” before, was that they come every month with an electricity bill. The book can give you a much broader picture of i.e. where they come from, and what they can do for you.
