My question to you is why are you such a pessimist that you think it's impossible without the use of fossil fuels to have a better life?
Wow way to slam the oversimplify lever into overdrive.
I'll try for a basis we might both be able to agree on here. Improvements in living conditions correlate positively with per capita energy consumption (From whatever available resource be it animal power to nuclear). Barring artificial increases to the cost of fossil fuels they are still by far the cheapest sources of available energy. You can build a gas powered vehicle and run it for years, for less than the cost of a battery pack for an EV. http://en.wikipedia.org/wiki/T... 1600$ U.S. how much does the battery pack on that Tesla cost ? That's transportation. They are also still the only reliable source for the electric grid with the exception of nuclear. You can talk about how cheap P.V. is all you want but without net metering backed up by a grid the economics are nowhere near as rosy.
So you raise the cost for people around the world to get the kind of things we consider basics not high life here just the basics, refrigerated food, safe water, communications systems that connect you to the world around you, opportunity to travel. Will making this more expensive and difficult for them to acquire make it impossible ? It's certainly going to make it harder and take longer and maybe not happen at all. It's for damn certain going to make sure some of those people will not get to that spot and not even have hope of getting there.
