computer parts posted:A single wind turbine is probably cheaper than a coal plant but it also won't give you nearly as much electricity. Each turbine is rated for 1-2MW depending on location, wind strength, and type. To match the current output of a single coal plant, something like ~600MW, you'd need at least 300 turbines. 300. Individual. Generators. Let's take this back to the US for a second, Greenpeace recently published a photo arguing that China has exceeded US Nuclear production with Wind alone. Its true, they have. China has around 117,000MW worth of Wind. US has 98,000 MW of Nuclear. Except that amount only covers 1/10th of China's power usage, the majority STILL being Coal, and their Coal usage is only growing. So, if we wanted to replace our 98,000MW of nuclear with wind, we'd need....49,000 wind turbines, but that's before you realize that most wind turbine farms only operate at 2/3rd their total capacity, if that.

It's cheapest when it's a small amount of wind, but it gets a bit more expensive the larger percentage of your power comes from wind. This is due to needing to build grid improvements to actually harness that power during high winds, otherwise that energy gets wasted, reducing its cost effectiveness. They measure up quite well on the technical and economic points. Generally, wind gets a ton of subsidies because the grid operators mostly like it (out of the renewable options, wind lacks a lot of the others' downsides), their lobby was pretty successful as a result, and of course, because subsidies are necessary to spur fast enough build-out. To the operator, it's always cheaper to try to nurse along an aging coal plant than to make a big capital investment to build something new. The easiest thing to do to find hard statistics is look for someplace that has a lot of wind power (I like Iowa) and then look at government reports and such about it. e: wikipedia has a lot of info for the uk: http://en.wikipedia.org/wiki/Wind_power_in_the_United_Kingdom CommieGIR posted:we'd need....49,000 wind turbines, but that's before you realize that most wind turbine farms only operate at 2/3rd their total capacity, if that. Generally, a wind generator gets an average of about 33% of its nameplate capacity.

Wind farm subsidies are great for the developer. For current farms, you get Renewables Obligation Certificates as you generate electricity, which energy suppliers are obliged to buy from you, providing a subsidy of something like £40/MWh generated. Coming along in the near future, we'll have contracts for difference. Essentially, you negotiate a strike price, and you receive the difference between the strike price and the day-ahead price of power as a subsidy. Energy companies are then billed for this subsidy. This means that you have pretty much no price risk on selling your power - it's guaranteed before you start planting turbines.

That was sort of what I was wondering about, is wind power actually practical outside of governments throwing money at it. Information seems to point at it being useful if you have a good location for it but possibly not likely to form the backbone of an energy economy. As we have a fair few people who hate wind turbines with the fury of a thousand suns, it's pertinent I think to be able to respond accurately to them.

Wind power is limited so it can never be the principal energy provider. If anyone is arguing this they are wrong. However, it's very, very cheap in the right places which makes it really dumb to not to use it if you can. I mean if you can put up some turbines in a good spot but don't, and instead burn more coal, you are literally paying money to spray toxins into your environment.

Yeah that's more or less probably my standpoint too, they have significant advantages of a small footprint and limited service required, no HGV traffic and such. Also better energy security going forward because once it's up, it's up, the world can melt around it but it'll still work. They don't require you to dig up shitloads of coal and burn it giving everyone COPD forty years down the line, and are remarkably good at not exploding, unlike some other forms of power generation. Downsides would probably be inconsistent generation (though you can work around that, and coal plants have the problem of being too consistent, necessitating the same solutions in order to be efficient) and being a bit weird to set up everywhere, more of a distributed solution than a centralized one.

blowfish posted:clearly only because germany does not run a mainly renewable grid yet My point was not that solar power as a the majority power source is a viable or even a good idea (it currently isn't, and maybe never will be), rather that if your energy generation mix can deal with a cloudy day, it can deal with an eclipse as least as well – whether it's 1%, 10%, or 100% from solar power.

The fact that the grid operators were able to reduce the risk from the eclipse to near that of an average day shows how much that has already done to create a more responsive grid. This was a stress test that Europe passed and that proves the viability of current levels of renewables penetration in the European grid.

The EIA actually knows what they are doing and the model they are using is particularly adjusted to the problems of renewables (http://www.nrel.gov/analysis/reeds/description.html). Also storage is an incredibly small part of the generation scenario: Storage is the hard to see sliver on top of wind in the installed capacity graph. Besides our current experience with wind shows us that we don't need to add large amounts of storage (or significantly increase generation reserves) to deploy wind at large percentages: quote:In regions with wind power contributions up to 20% of annual electrical demand in 2013, electric power systems operated reliably without added storage and with little or no increase in generation reserves [7]. Wind has also been proven to increase system reliability during some severe weather events. For example, in February 2011, cold weather disabled 152 power plants in Texas, mostly coal and natural gas. Wind generation produced approximately 3,500 MW of output during this event, helping to avoid outages [135]. Experience with wind generation confirms that opportunities exist to increase grid operating effi- ciency and reduce costs by increasing flexibility.55

An unfortunately large number of environmentalist projects are infected with the usual idiocy that nuclear is just as bad coal. The last "roadmap plan" I saw (I forget the source, earlier in this thread certainly) showed nuclear being replaced primarily by biomass to the tune of about 40% of total generation. This one shows appears to show nuclear getting replaced primarily by natural gas. I'm as confused as you are why anyone would think this is a good idea.

But as of now, doing something as incredible as electrifying and nationalizing half the cars in the US is a pipe dream in itself. One of the things I feel like I repeat a lot (because it surprised the hell out of me, and it's a mistake I see almost everyone else making too) is that the storage needed due to the variability of wind is NOT necessary to make up for a shortfall of power generation. It's necessary to make use of power generated when winds are HIGH. There's EXCESS power. Yes. We can use electric cars to do this, just fine, no problem. Offer people a slight discount on power if they use "eco-charge" on their cars. Charge at 60% normal rate, unless the grid is yelling "hey everyone I've got power to spare! gimmee all you got!" in which case, hit 100%. There's no discharging of those batteries back into the grid. Not necessary.

Does it greatly matter whether the rest of the generation is supplied by nuclear or gas power? You don't have to take the entire report as written, it would seem quite possible to look at the information provided about wind power alone and possibly incorporate that into a more accurate assessment which includes the renewal of nuclear energy. Essentially I don't get why "there is an error so all the information is wrong" is valid reasoning.

Wind Vision anticipates nuclear and coal retirements in part due to low natural gas prices. There are currently 5 reactors under construction in the U.S., and four of them are plagued by "dismal cost overruns and multi-year delays," according to the Wall Street Journal. That hardly sounds like the start of a promising growth trajectory. It's been proven by experience that grids can handle large percentages of wind and solar, you don't need nuclear (or storage for that matter) for a low-carbon energy mix. As many of you said, Wind Vision is a roadmap. The point of the report is to show people that the U.S. can achieve this growth in wind power.
