Wind and wave energy not so renewable

[Lord Testicles]

Build enough wind farms to replace fossil fuels and we could do as much damage to the climate as greenhouse global warming
WITNESS a howling gale or an ocean storm, and it's hard to believe that humans could make a dent in the awesome natural forces that created them. Yet that is the provocative suggestion of one physicist who has done the sums.
He concludes that it is a mistake to assume that energy sources like wind and waves are truly renewable. Build enough wind farms to replace fossil fuels, he says, and we could seriously deplete the energy available in the atmosphere, with consequences as dire as severe climate change.

Doesn't seem to be a problem we have to worry about any time soon, much like the idea that direct waste heat (as opposed to heat retention caused by CO2 emissions) will cause the poles to melt.

Also, the article mentions wind and wave power, but those are only two out of at least five renewable technologies: there is also tidal, hydro-electric and solar. Likewise geothermal derives its energy from different processes.
