How much electricity do solar and wind make on a global
scale? Answer: “Not much”
Simple numbers are hard to get, so when Anton Lang pointed
me at the EIA site (U.S. Energy Information Administration), I wanted to give
everyone the straight answer to the question: just how much electricity
do renewables make on a global scale? The EIA has the only database in
the world with a this much accuracy.
The answer is that 80% of our electricity comes from the
fossil fuels and nuclear that the Greens despise. Hydroelectricity, with all
its pluses and minuses, produces a serious 16% of the total. But all the vanity
renewables bundled together make about 3.5% of the total.
Wind power is a major global industry but it’s only making
in the order of 1.4% of total electricity. And solar is so pathetically low
that it needs to be bundled with “tidal and wave” power to even rate 0.1%
(after rounding up).
For all the fuss and money, if the world’s solar powered
units all broke tonight, it would not dent global electricity production a jot.
No one connected to a grid would notice.
These are the total global numbers from the US Energy
Information Agency (The EIA) for 2009.

The figures here are the most recent whole year figures
available. Some figures for 2010 are not listed on the EIA site yet. Even
though there is more solar and wind power capacity now, China has been adding a
2GW coal fired station every week or two, so I’m led to believe that the latest
pie graph would not look altogether different.
