It has struck me (a bit belatedly maybe) that there are three essential transitions that we need to make if we are to achieve a genuinely sustainable and reasonably comfortable and happy existence in the finite environment of one planet:fifthcolumn wrote:...
Consider this: say we built an all-electric economy but with quality products that didn't wear out as fast as they do in our consumer economy of today.
In theory we could grow the economy based purely on services with a little bit of churn on the manufactured end...
1) Renewables-based, almost entirely electric energy capture for heating/cooling, mechanical work and transport;
2) Closed system or "Cradle-to-Cradle" processes for all manufacturing and consumption of stuff, all activity that consumes mineral resources;
3) Agricultural systems that don't degrade any of resource bases that food production depends on - e.g. based on permaculture principles: mimicking natural systems, low energy input, low water usage, top-soil protecting/building.
