More Wind Craziness

I still contend that wind is, except in a few niche applications, probably the worst alternate energy source.   Other forms of energy like solar have issues, but there is a lot of reason to believe these a fixable over time with better technology.  Wind is just a plain dog.

One of the biggest problems with wind is the need for backup power.  Because wind's lapses are hard to predict, a lot of fossil fuels have to be burned in spinning, hot backup capacity ready at a moment's notice to take over.  In Germany, the net effect has been very little substitution of fossil fuel burning despite an enormous wind investment

As wind power capacity rises, the lower availability of the wind farms determines the reliability of the system as a whole to an ever increasing extent. Consequently the greater reliability of traditional power stations becomes increasingly eclipsed.

As a result, the relative contribution of wind power to the guaranteed capacity of our supply system up to the year 2020 will fall continuously to around 4% (FIGURE 7). In concrete terms, this means that in 2020, with a forecast wind power capacity of over 48,000MW (Source: dena grid study), 2,000MW of traditional power production can be replaced by these wind farms.

Natural gas makes this situation a little better, as natural gas turbines can be brought up much faster than, say, an oil or coal-powered plant.  But the duplicate investment is still necesary

Britain's richest energy companies want homeowners to subsidise billions of pounds worth of gas-powered stations that will stand idle for most of the time.

Talks have taken place between the Government, Centrica, owner of British Gas, and other energy companies on incentives to build the power stations needed as back-ups for the wind farms now being built around the country.

It is understood 17 gas-fired plants worth about £10 billion will be needed by 2020.

The Energy Department has been warned that without this massive back-up for the new generation of heavily subsidised giant wind farms, the lights could go out when the wind dies down.

Sam Laidlaw, chief executive of Centrica, said renewables, such as large-scale wind energy, were intermittent and required back-up generation, a role gas was uniquely qualified to fill.

But as power stations that operate only intermittently would not be financially viable, Laidlaw said: 'The building of new gas-fired capacity must be incentivised so that gas can fulfil its role as a bridging fuel.'

Great.  So we have wind power, which is not financially viable so it must be subsidized, that required backup power plants to be constructed, which will not be financially viable so gas plants must be subsidized.

I have an idea, why not have gas plants which are financially viable serving the base load and just get rid of wind and this double subsidy all together?
