Part of the May Permaculture season at the Workhouse. (This is now confirmed.. Thanks to the Long Now Foundation for permission to screen this lecture on the potentials fo newewable energy)
With climate change on the one hand and peak oil looming on the other, it feels certain that we are going to have to have a major rethink about energy. Probably right now would be a good time to be doing that!
The world currently runs on about 16 terawatts (trillion watts) of energy, most of it burning fossil fuels. To level off at 450 ppm of carbon dioxide, [as currently advised] we will have to reduce the fossil fuel burning to 3 terawatts and produce all the rest with renewable energy, and we have to do it in 25 years or it’s too late.
Currently about half a terrawatt comes from clean hydropower and one terrawatt from clean nuclear. That leaves 11.5 terawatts to generate from new clean sources.
Could the world actually do this? and what would it actually feel like? Would our lives be recognisable to what they are now?
Saul Griffith answers these questions, in a strangely uplifting yet challenging presentation.
‘Very informative and very well presented‘
