How many wind turbines will it take to get to 20%? Is that 20% of current electricity production or ALL energy. I'm thinking it would take many millions of generators. The support requirement alone would be immense. It would be like the suburbia of energy production.
Let's look at the nuclear issue. Nuclear currently provides about 15-20% of total electricity usage, about 2-3% of total energy usage. Fossil fuels make up 90%+ of total energy production. If nuclear was to rise to 20%-30% of current total energy production we would need approximately 4000 more plants. There are fewer than 500 now. I don't see the world scaling up to 100's of new plants per year very soon.
Western Europe uses about half the energy per person as the U.S. Even if the U.S. became as efficient it would easily be offset by the 3+ billion in China and India.
If we can manage transport thru electricity we are still no where near equilibrium with water, atmosphere, desertification, and many other things. Peak Oil is but one of many problems and eventually we will pay the price for living so far beyond our means.
The only solution is a TOTAL solution to all our sustainability issues.
