I was watching the video below, thinking it was all pretty unremarkable…. until this line:
there are seventy-two TeraWatts of useable wind energy in the world: the world only uses about eight to nine terawatts of energy
That has to mean that one day, all energy will be renewables – with all that unused energy whooshing round, why would we not want that to happen. Factor in the immense potential for solar energy, and the future really could be entirely green.
