I have just came across another interesting view on sustainable energy and what it really means.

Did you know that for Britain to get 25% of its energy from growing energy crops, that would require 75% of the country to be covered with biomass plantations?

If this topic interests you make sure you read at least the synopsis – which in fact is all I had time to skim for now (but I will make sure I download the epub to the iPad and go through it during the weekend).

The author David MacKay has made the book available in all sorts of formats (web, ereaders, pdf, etc) so you just don’t have an excuse not to read it because it is free. You can find all about it here.

Credits: I found this book via @martinvars which I follow since I found he was twitting. If you are into entrepreneurship stuff you just can’t miss Martin Varsavsky, with some failures like the rest of us, and some huge (and I mean huge!!!) successful endeavors, he had always some interesting thoughts to share. I remember meeting Martin once at Ya.com offices in Madrid, back in 2001 and I got a very good impression ever since then.
