Au contraire..
Efforts at education are never wasted efforts and people are talking geothermal...
Yes, they are. Nancy Pelosi cited it specifically amongst solar, wind and hydro.. She runs Congress, or didn't you hear?
I could care less who gets credit for what idea and when. The only thing I care about is that we make our nation stronger by cleaning it up and becoming independant and strong again. Geothermal is part of that plan.
Who cares who gets the credit? As long as geothermal happens.
****
More importantly, start learning about nuclear and how all that danger and radioactivity and costs and hassel exists just to run simple steam turbines....just astounding waste and risk...to produce steam...steam...
Now on Highway 395 and look to the left and right all the way up the east side of the Sierra Nevadas. Steam. Coming right out of the ground, without nuclear waste included.
Scientists have been urging officials for years to utilize this safe, clean energy source. Nothing...nada...zip..
BigOil wants tricky energy. Price-fixing energy. Geothermal just won't do.
Let's harvest steam instead of producing it with filth and antiquated, dangerous technologies. Let's stop being embarassed in the 21st Century.

Here are some gals relaxing in the effluent of a geothermal plant. Imagine doing that at a nuclear plant? They've been trying to clean up one nuclear plant I know of and have been at it for three decades and still aren't totally satisfied with the results..
Geothermal. Look it up.

But don't think that you're going to get any satisfaction for the changes because they will claim it was their ideas right from the start. Just look at how the right is now taking credit for accepting there is a need for alternative energy when only a few months ago they were claiming that oil would see them through to the end of times.

HOW IS ELECTRICITY GENERATED USING GEOTHERMAL ENERGY?
In geothermal power plants steam, heat or hot water from geothermal reservoirs provides the force that spins the turbine generators and produces electricity. The used geothermal water is then returned down an injection well into the reservoir to be reheated, to maintain pressure, and to sustain the reservoir.
There are three kinds of geothermal power plants. The kind we build depends on the temperatures and pressures of a reservoir.
A "dry'" steam reservoir produces steam but very little water. The steam is piped directly into a "dry" steam power plant to provide the force to spin the turbine generator. The largest dry steam field in the world is The Geysers, about 90 miles north of San Francisco. Production of electricity started at The Geysers in 1960, at what has become the most successful alternative energy project in history.
A geothermal reservoir that produces mostly hot water is called a "hot water reservoir" and is used in a "flash" power plant. Water ranging in temperature from 300 - 700 degrees F is brought up to the surface through the production well where, upon being released from the pressure of the deep reservoir, some of the water flashes into steam in a 'separator.' The steam then powers the turbines.
A reservoir with temperatures between 250 - 360 degrees F is not hot enough to flash enough steam but can still be used to produce electricity in a "binary" power plant. In a binary system the geothermal water is passed through a heat exchanger, where its heat is transferred into a second (binary) liquid, such as isopentane, that boils at a lower temperature than water. When heated, the binary liquid flashes to vapor, which, like steam, expands across and spins the turbine blades. The vapor is then recondensed to a liquid and is reused repeatedly. In this closed loop cycle, there are no emissions to the air...
.. WHAT ARE SOME OF THE ADVANTAGES OF USING GEOTHERMAL ENERGY TO GENERATE ELECTRICITY?
Clean. Geothermal power plants, like wind and solar power plants, do not have to burn fuels to manufacture steam to turn the turbines. Generating electricity with geothermal energy helps to conserve nonrenewable fossil fuels, and by decreasing the use of these fuels, we reduce emissions that harm our atmosphere. There is no smoky air around geothermal power plants -- in fact some are built in the middle of farm crops and forests, and share land with cattle and local wildlife.
For ten years, Lake County California, home to five geothermal electric power plants, has been the first and only county to meet the most stringent governmental air quality standards in the U.S.
Easy on the land. The land area required for geothermal power plants is smaller per megawatt than for almost every other type of power plant. Geothermal installations don't require damming of rivers or harvesting of forests -- and there are no mine shafts, tunnels, open pits, waste heaps or oil spills.
Reliable. Geothermal power plants are designed to run 24 hours a day, all year. A geothermal power plant sits right on top of its fuel source. It is resistant to interruptions of power generation due to weather, natural disasters or political rifts that can interrupt transportation of fuels.
Flexible. Geothermal power plants can have modular designs, with additional units installed in increments when needed to fit growing demand for electricity.
Keeps Dollars at Home. Money does not have to be exported to import fuel for geothermal power plants. Geothermal "fuel'" - like the sun and the wind - is always where the power plant is; economic benefits remain in the region and there are no fuel price shocks.
Helps Developing Countries Grow. Geothermal projects can offer all of the above benefits to help developing countries grow without pollution. And installations in remote locations can raise the standard of living and quality of life by bringing electricity to people far from "electrified" population centers...
