Myth 1: that there is a requirement for gas-powered backup to counter the unreliability of wind power. “This is plainly untrue,\” said Bob Ward. “Only 1% of carbon savings are wiped out, because there are many ways of managing both demand and supply due to the intermittency of the wind.\” The report says: \”The cost penalty and grid system challenges of intermittency are often exaggerated. There are several other ways of compensating for the variability, such as bulk storage of electricity, greater interconnection, and a more diversified mix of renewable sources, as well as measures to manage demand, like smart grids and improved load management.”
Wind\’s just great as long as we can turn the lights out the wind isn\’t blowing. Or is blowing too hard.
Myth 2: that onshore wind is expensive. “We found that it is the cheapest of all low carbon forms of electricity generation,\” said Bob Ward.
It may be the cheapest form of renewable power (although I know some people with dams who would disagree) but it is still expensive. That\’s actually our problem Bob: renewables are expensive. If they were cheap we\’d all use them and we wouldn\’t have this climate change problem.
Myth 3: that using gas power generation is low carbon and will help us meet our climate commitments. “This is only true if we stop using gas in 2020,\” said Bob Ward, because at that point emissions need to drop further than relying on gas can permit.
This is abject twattery. How much climate mitigation we do as opposed to how much adaptation depends upon the cost of doing the mitigation. It\’s the cost of relying or not relying upon gas (or wind etc) that determines what we do, not anything else.
