The cost of solar and wind does not include the need to upkeep traditional gas and oil electric producing plants. You need them when there is no sun or wind. So these old plants must be ready to operate and at full peak power. It's not like you can shut them down. Also, private installation of solar may reduce that person';s cost for electricity. But it shifts it to those who didn;t convert as they still must pay for the upkeep of the carbon plants with less customers to pay for their upkeep. I'm not aware of any locality charging solar users for that issue.
Also, government is paying subsidies for people to install solar. That's just shifting the costs to others.
I hear this a lot, that we have to keep some fossil fuel plants online in case the wind stops. But while the wind is blowing, you're not using any fuel, are you? At the present time, natural gas and whatever else they burn in those places is cheap, but you have to plan out these utilities 25-50 years, the fact that today's price is low is utterly irrelevant. There may come a time, and probably will, when the savings on not burning the gas when the wind is blowing will be worth keeping those plants online.
It is always the same, people calculate how much it costs to do things, but they never calculate what it will cost NOT to do them.
As for governments subsidizing solar and wind, please stop repeating this. They've been subsidizing Big Oil since before we were born, it's just that no one ever adds that up. A few months ago, the Cdn federal government announced support dollars for the downturned Alberta oil industry, which is going through one of its semi-regular down cycles, and that which for some reason has surprised everyone again. And current day taxpayers have to pay for the clean-up of abandoned oil and gas wells because the companies that ran them are gone. There are probably a thousand other examples. How come no one ever adds up what THAT costs?
The Alberta tar sands companies use lots (up to a third, I've read) of the available fresh water in the watershed up there and spits it back out into polluted ponds. How much are they paying for that water? Sounds like a subsidy to me.
Please stop analyzing things as if we're distorting the free market. The corporations are the FIRST to line up at the taxpayer trough. There's not a single one of them that believes in the free market. They're scared to death of the free market.
