David Mackay delivers a renewables reality check

Posted by Jason Ramsdale on 3 December 2015 at 3:40 pm

In a fascinating and inspiring TED (Technology, Enertainment, Design) talk David Mackay, an engineer and physicist at Cambridge University, talks us through how much space would be needed to power the entire UK as stands (with its petrol cars, gas boilers, electricity from coal etc) from renewable energy on its own.

The number, it turns out, is pretty big! About the same area as the UK land mass. But, he goes on to show how a combination of renewable energy at home and abroad alongside nuclear power, energy-efficient transportation and energy awareness can keep Britain’s lights on.

He calls for everyone to “stop shouting and start talking” and believes with a little compromise and international cooperation we can build a greener tomorrow.


You can download a free PDF copy of David MacKay's book Sustainable Energy - without the hot air. It's a fascinating read.
