ALTERNATIVE ENERGY GEOTHERMAL ENERGY - This comes from the internal heat of the earth. Energy can be and already is accessed by drilling water or steam wells in a process similar to drilling for oil. Geothermal energy is an enormous, underused heat and power resource that is clean. These resources range from shallow, ground to hot water and rock several miles below the Earth's surface, and even farther down to the extremely hot molten rock called magma. GEOTHERMAL RESERVOIRS - Mile or more deep wells can be drilled into underground reservoirs to tap steam and very hot water that drive turbines that drive electricity generators. TYPES OF POWER PLANTS : 2. Flash steam plants which pull deep, high-pressure hot water into lower-pressure tanks and use the resulting flashed steam to drive turbines. 3. Binary cycle plants which pass moderately hot geothermal water by a secondary fluid with a much lower boiling point than water. This causes the secondary fluid to flash to vapor, which then drives the turbines. 4. Technology is being developed to drill down several miles everywhere beneath the Earth's surface to the hot, dry rock being heated by the molten magma directly below it. 5. All
we have to do is drill into this rock, inject cold water down
one well, circulate it through the hot, fractured rock, and draw off the heated water from another well. Sounds pretty
simple, doesn't
it. The earths pressure is constantly making new 6. Geothermal energy is an enormous, underused heat and power resource that is clean (emits little or no greenhouse gases), reliable (average system availability of 95%), and homegrown (making us less dependent on foreign oil). 7. Let's use some of this clean abundant energy to fuel our future.
