The argument that preventing power outages with wind means we need to keep coal or gas plants running reminds me of the false dichotomy between coal and nuclear. Such concerns would be rendered moot through a mix of different renewable and ecological forms of power production.
Solar roof panels + solar plants producing hydrogen + ocean-wave capture hydropower + wind + secondary biomass (of shit and waste) + geothermal. All in a new smart grid.
Not all of these can go out very often at the same time, and then, so what? We also have blackouts under the present system.
In the cities, build light rail, create covered bike lanes and redesign to cut commuting needs. Convert buildings to cut down on heating costs. End the empire (biggest waste of energy of all). Stop subsidizing agribusiness corn-for-meat and put that into subsidies for more localized, organic agriculture using modern means to raise density. It's all technologically doable today. You could throw a couple of hundred billion saved off the war machinery into Apollo projects for developing the various technological wild-cards.
The only "problem" is that it would take an enormous investment and many years of full employment to install enough of these facilities and convert the infrastructure. You'd also have to fund giant new departments at the universities to educate the new specialists. All of which, of course, is not a problem at all, except to the economic libertarians. All this is the solution to the economic depression. There is no downside, except to the balance sheets of certain currently dominant institutions that rely on monopoly power over highly centralized forms of energy production, run by fools who care only about their own pecuniary interests, to the point of killing their own grandchildren.

All other forms of electricity generation also suffer outages, only renewables get noticed. Our children will comes to terms with 'not always on', and will save themselves much wasted capital and resource consumption.

It supports that gas/methane fired plants, whether steam-driven gen sets or turbines, can be powered up in hours, not days as you claim. I'll bet you cannot find a ref to support your claim, it is just so far from the truth. Luckily it is easy to admit error, and it builds trust and confidence!Stephen Morgan wrote:wintler2 wrote:Stephen Morgan wrote:As it can take several days to cycle up a gas turbine plant,

Cash is obtainable for its face value. If I had to put in some large capital investment to be able to use cash, and then would only be able to use it at times decided at random, I'd probably stick with the debit card.

Generating a lot of electricity is a big deal, you ever been to a coal mine or a hydro dam? What do you reckon the capital investment is for this?

wrong about scalability of geothermal and reliability of hydro and geo,
and cite 'a movie on the telly' and Private Eye as your sources.
I'll shortly let your opinion have all the room it likes.
Renewables are better than fossil fuels & nukes because they aren't directly toxic to the biosphere.
But they wont run business as usual;
on currently built capacity, not even 5% of business as usual, and there may not be a whole lot more capacity built.
The sooner we face that reality the more likely our greatgrandkids will have some direct experience of electricity rather than just stories.
