Sustainable Energy: Without the Hot Air


Britain gets 90% of its energy from fossil fuels. When we talk about moving Britain into a sustainable energy future – one that is less dependent on fossil fuels – what does that look like? There is a fantastic video on YouTube that stars Cambridge University’s Dr. David MacKay, a physicist and pragmatic converser in energy systems. His 2009 book, Sustainable Energy: Without the Hot Air has received rave reviews and is the most recent addition to my “to-read” list (you can download this book for free on the book’s website or buy it via amazon).

For now… listen to Professor MacKay’s discussion of our energy use, in lightbulbs.
