Parabolic Trough Solar Thermal Electric Power Plants

摘要

Each year, the United States is becoming more dependent on foreign sources of energy. Already more than 50% of the oil consumed in the United States is imported. Environmental pressures to improve air quality and reduce carbon dioxide (CO2) generation are driving a shift from coal to natural gas for new electric generation plants. Domestic sources of natural gas are not able to keep up with growing demand, causing supplies of this key energy source to become increasingly dependent on foreign imports as well. The use of natural gas as a source for hydrogen generation could further aggravate this situation in the future.
