Kittenkoder, if I could ad something on Geothermal. Currently the most expensive power is geothermal. Its also unregulated and extremely polluting. Fortunately its all toxic heavy metals and radioactive materials so the pollution does not become airborne. Take a look at the dozen or so Geothermal plants on the Salton Sea. Each plant need a well, the wells are drilled 10,000 feet deep, to a pool of water sitting a bed of lave on the San Andreas fault. The wells are located up to three miles away from the plant, requireing a mile to three miles of 48" concrete lined steel pipes. Inside the pipes is the brine from the wells. One gallon of Brine weighs about 10 lbs compared to around 8 lbs for water. The extra 2 llbs is the toxic metals, cobalt 60, cesium, strontium, and a shitload of arsenic. The pipes travel along the Imperial valley farmland and the Pacific flyway for waterfowl. These pipes burst all the time, spewing the contents onto the farmland. The well is a violent well, it shakes and bounce three or four feet into the air, that shaking is transmitted up and down the pipeline all the way to the plant, tremendous stress, much damage, more maintenance required than any other source of power. The well are constantly moved as the pressure drops so they are constantly replacing the pipes.
Maintenance of the plant requires opening of the systems allowing the toxins out. I know, I was there, I even suffered arsenic burns, arsenic on the skin only penetrates the first few layers of skin so I was not poisoned. I worked all night, a pool of contaminated water below the system we were inspecting, crickets walking across the tiny pool, they die before they get across. The ones not in the pool are kind of fine, they just get the poison on thier legs. This plant is on the Pacific flyway for birds, millions, they eat the crickets, how much contamination I do not know, I have seen a grid of farmland on the wall of Cal Energy (I believe cal energy sold thier interest) that showed which farmland was bought due to accidents.
I have seen people dressed in more protective gear than I wear inside nuclear power plants.
Geothermal is a toxic witches brew.
