This is a temporary page of Professor David MacKay's book Sustainable Energy Without the Hot Air. Links to this page will likely break in the near future.

Without The Hot Air

This section of the website is entirely based on Prof. David MacKay's work. It is offered with deep gratitude for the emails over the years and his book "Sustainable Energy Without the Hot Air" which was a great source of knowledge, and inspiring realism.

It is offered here as a suggestion for how to ensure that the original knowledge continues to be built on by putting it into a wiki which will allow it to be kept up to date with the latest data from changes in policy, resources, technology, weather, energy utilisation, and economics.

In the initial post for this project I raised some questions. I would be grateful for your assistance if you are in a position to help answer them. Thanks!
