The reason is the fucking wind doesn't blow all the time or it doesn't blow hard enough or it blows too fast. And the reason your costs are low is because of tax payer subsidies. What will it be when those stop because they will have to eventually.Your math is wrong ... for a name-plate capacity of 600 kW we'd have 5,259,600 kW-hrs per year ... then your ratio would be 1 ... if we choose to shut our power plant down 75% of the time, then of course we'd only see 25% of the output ... duh ... the main reason to shut down is lack of demand ... say 2am on a mild fall early morning ... no A/C, no arc welders, no iron smelting, no cement making ... just a few little children's nightlights running (LED's) ... we're better off running a 50 kW unit and save maintenance costs on the big units ...Wrong , Corky.
I have faith the Americans are stupid enough to vote for a politician of the 2 major parties and that they actually believe their vote matters and that the fuckiong government cares about them.
And unlike you morons I don't make shit up
The Capacity Factor
Another way of stating the annual energy output from a wind turbine is to look at the capacity factor for the turbine in its particular location. By capacity factor we mean its actual annual energy output divided by the theoretical maximum output, if the machine were running at its rated (maximum) power during all of the 8766 hours of the year.
Example: If a 600 kW turbine produces 1.5 million kWh in a year, its capacity factor is = 1500000 : ( 365.25 * 24 * 600 ) = 1500000 : 5259600 = 0.285 = 28.5 per cent.
Capacity factors may theoretically vary from 0 to 100 per cent, but in practice they will usually range from 20 to 70 per cent, and mostly be around 25-30 per cent.
The above is true for ALL power plants of any kind ...
Ah ... but solar/wind/hydro shuts down at times NOT of our choosing ... something well known since the first drought at the first earthen dam built by cro-magnon man ... duh ... and solar is the worst ... with a name-plate capacity of 200 W/m^2, we immediately lose half due to night-time, and half again while the sun is low to the horizon ... thus your 25% actual production ...
These people think intermittent power supplies will be able to power us into the future.
No ... this is strictly your own misunderstanding ... I'm glad someone has set your straight ... no one else in the entire world believe solar panels worked at night ... no one else believed wind will work on calm days ... no one else thinks hydro works when the river runs dry ... if you're only listening to the stupidest people you can find, maybe your rhetoric will come off just as stupid ...
I've ran the numbers for solar where I live, and it fails miserably ... no way can I compete with grid power ... the same with wind and hydro locally ... not with the main BPA trunk lines running down to California just a few miles away ... those are connected to a solar farm where it's usually sunny, wind mills where it's usually windy and hydro on a river that has never run dry ... my cost is 6.3¢/kW-hr ... and that river is always running, we always have power ... this cost has been going down as we add more wind and solar, at a time when fossil fuel electricity costs are going up ... our future doesn't depend on the availability of cheap oil ...
What about yourself ... what does your future look like when fossil fuels start running out? ...
In fact I think wind and solar add up to what 5% of the power production in the country yet have received some 30 billion in subsidies. Hydro will never get any bigger because we won't build any more dams like Hoover.
You might want to read what I said. It is WIND that only produces 25% of its rated capacity not solar.
And if you bothered to read anything I have posted you would know that I realize we will stop using fossil fuels.
What we need is to start our research into the next generation of nuclear reactors, namely LFTR reactors because there is no way that wind and solar can even meet our current needs without fossil fuel backups never mind the exponentially increased demand of an entirely electric powered country.
And I do think we should get off fossil fuels as quickly as possible but wind and solar ain't ever gonna cut it.
