A reality check on Renewable Energy

23 10 2018

Hat tip to my friend Shane who put me onto this TedX lecture…….  well worth sharing with your ecotopian friends! It does show how Australia – and Canada –  with very low population densities, are in not a bad position, except of course for the fact they are nowhere near the places with high densitity populations. You can’t beat arithmetics and physics…….

How much land mass would renewables need to power a nation like the UK? An entire country’s worth. In this pragmatic talk, David MacKay tours the basic mathematics that show worrying limitations on our sustainable energy options and explains why we should pursue them anyway.
