The Power Grid Can't Handle Wind Farms
DesScorp writes "The Times reports on the problems of adding wind farms to the power grid. Because of the grid's old design, it can't handle the various spikes that wind farms sometimes have, and there's no efficient way to currently move massive amounts of that power from one section of the country to the other. Further complicating things is the fact that under current laws, power grid regulation is a state matter, and the Federal government has comparatively little authority over it right now. Critics are calling for federal authority over the grid, and massive new construction of 'superhighways' to share the wind power wealth nationally. Quoting the article, 'The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.'"
The next time you drive by a nuclear plant take a look at the transmission infrastructure. You might see three different sets of pylons leaving each with a couple of 500kV circuits.
It takes wires to move electricty from generation to load, I don't know why they are surprised that when they build a wind farm in the middle of nowhere there transmission capacity to handle all that extra energy.
Especially since everybody says they have hardly built anything new in the way of transmission...of course there is no spare capacity!
I just toured a nearby dam, and was presented some very insightful ideas.
Nuclear and coal power are great for handling base load because they provide consistent power.
But peak load is where the money is; turning on power systems when they're needed to match the load at that second. Solar, wind, and water are all peak-load power supplies because they are not always consistent, vary widely according to weather and time of year and regulations, and can be very unclean with spikes. This is why these power systems cannot replace base load systems yet.
The solution is to even out our peak load systems so that they are more consistent and more like base load systems. Whether that's tying many different types together and hoping they even out naturally, or storing the energy in some kind of battery in the middle.
Since battery technology is nowhere near ready, a viable option is to store water in reservoirs behind dams, using wind and solar energy to pump water up, then releasing it evenly through a generator. This is even being employed in some countries.
You know its not all milk and honey. Theres a good pile of evidence that this Texas wind thing is one giant con so that Oil man Mr. Pickens can use newly created government power of eminent domain to snatch up land and sell his water pet project under the radar. Like they always say, follow the money.

for those who won't read it Pickens has been buying rights to a massive water reserve in Texas and has been having trouble building a pipeline through peoples property, so he is buying the law instead "In January, 2007, the Texas Legislature convened.. helped win Pickens a key new legal right. It was contained in an amendment to a major piece of water legislation. The amendment, one of more than 100 added after the bill had been reviewed in the House, allowed a water-supply district to transmit alternative energy and transport water in a single corridor, or right-of-way." and then "Pickens still needed the power of eminent domain if he was going to build his pipeline and wind-power lines across private land. And by happy coincidence, the legislators passed a smaller bill that made that all the easier. The new legislation loosened the requirements for creating a water district."
Long story short he's creating a new water and power district to sell this and is using public feel good green hype to get subsidy's and push through his new project that will drain a water resource that is very slow to renewal, out from under everyone else around it, to sell at low prices to Dallas, which is one of the most wastfull cites in Texas when it comes to water. Anyone who thinks someone who was part of the 80's raiders and swift boating can actually do something without a hidden con is a fucking idiot.
They could start storing energy thermally:
Give houses a large tank of water. In the winter heat the water when there is an electricity surplus, then use the hot water to heat the house. In the summer cool the water when there is an electricity surplus, then use the cold water to cool the house.
That would be a very environmentally friendly and almost 100% efficient way to store the energy. It would be much cheeper than batteries or any other storage method. And when you consider that 80% to 90% of domestic electricity is used for cooling or heating it would go a long way towards dealing with the problems of storing renewable energy.
Well,
It'd be cheaper than 5-years in Iraq, Yankee. And do a lot more towards keeping you secure.
But as a product of what America calls "education", you might find some dispute with that bright light of reason.
"Speaking the Truth in times of universal deceit is a revolutionary act." -- George Orwell
When the supply of wind power collapses send a message through a network to appliances which can be switched off for a few minutes without causing too many problems.
Heaters could work this way. They could pay a lower charge for energy in return for participating in load balancing.
