The article explains that fossil fuels like coal, gas, and oil may be depleted while renewable sources such as wind, sun, rushing water, or geysers offer endless potential. It notes these renewables can power plants only where conditions are sufficient to generate electricity.
The Solar One plant near Barstow, California, uses 1818 heliostats arranged around a 300 foot tower to focus sun rays on a boiler. Steam drives a turbine to generate electricity, with energy storage to run after sunset or during cloud cover. Utilities test solar viability in their regions.
Water builds up behind a dam and, when released, falls to turn turbines and generate electricity using gravity. This relied upon energy process uses potential energy to drive generator systems in hydro plants.
A few wind farms in the West are producing electricity for power plants. Wind farms are areas containing hundreds of windmills used to harvest wind energy.
Geothermal energy is sourced from deep within the earth. Geyser fields near San Francisco emit steam used to generate electricity in the region.
Practical safety tips advise avoiding playgrounds near poles and wires, keeping appliances away from water, not flying kites near lines, never touching switches in wet places, staying clear of fallen power lines, and unplugging appliances when not in use.
A step by step overview of coal power generation from fuel delivery to distribution. Coal is ground and burned in a boiler to make steam. Steam turns a turbine connected to a generator, producing electricity. The generator's rotor moves coils, inducing current. Electricity goes to a transformer to raise voltage, then along transmission lines to substations where voltage is lowered for use.
Preheat to 325 degrees bake for half an hour. Cool completely then cut into even squares.
