For energy website followers perhaps the most crucial to watch is the American Energy Information Administration's monthly update on world oil production: http://www.eia.doe.gov/emeu/ipsr/supply.html
This shows that the peak year for conventional oil production was 2005 and every year from now on global oil production will decline.
With what is this to be replaced? Gas production is expected to peak within a few years, coal within a couple of decades.
Uranium, although not a "fossil fuel", is also finite, and production will probably peak around the same time as coal.
Of course wind energy is intermittent and expensive. If it weren't we would have continued using it and not replaced it with coil, oil and gas.
But, every kWh of wind energy produced is, more or less, 1 kWh of fossil fuel saved.
