How much land mass would renewables need to power a nation like the UK? An entire country's worth. In this pragmatic talk from TEDxWarwick, David MacKay tours the basic mathematics that show worrying limitations on our sustainable energy options and explains why we should pursue them anyway.
GOALS
David MacKay wants to use hard math to show the actual possible future that we could get using renewable evergy, and what the limitations are.
ACTIVITY DESCRIPTION AND TEACHING MATERIALS
We need a plan that adds up. We need to stop shouting and start talking. And if we can have a grown-up conversation, make a plan that adds up, and get building -- maybe this low-carbon revolution will actually be fun." (David MacKay)
