Fossil fuels such ascoaland oil is used to generate heat. This heat converts water into steam at very high temperature and high pressure. This steam at high pressure drives a steam turbine. Therotating shaft of the steam turbineis coupled to the armature of the alternator to generate electric...
The most popular way to make steam is to heat water by burning coal. It's also possible to use controlled nuclear reactions to turn water into steam. You can read about the various types of power stations in How Hydropower Plants Work, How Wind Power Works and How Nuclear Power Works. ...
Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it. Sure, you can flee from the world of crisscrossing power lines and live your life completelyoff the grid, but even at the loneliest corners of the world, electric...
Most electricity is generated by burning coal and other fossil fuels. Every time you turn on the lights, you create a little pollution. (See the sidebar.) In fact, the average home pollutes more than the average car! (See my Carbon Footprint Calculator for the numbers.) So saving ...
The hot water got its energy from the kettle you put on the stove or plugged into the electricity outlet. And where did the electricity come from? Most likely, from a power plant, which burned a fuel such as gas, coal, or oil to release the energy it contained. But where did the ...

Nanosolar claims that its super-efficient manufacturing process and revolutionary semiconducting ink can reduce the cost of making electricity from sunlight to a mere 30 cents per watt. If that holds true, solar may finally be competitive with coal. Staff Engineer Addison Shelton works with a solar...
Fossil fuels make use of a considerable amount of water to get converted to electricity. Not only this, coal and gas-fired power plants also use huge quantities of water to get cooled. During hydraulic fracking, which is a process of extracting natural gas as well as oil, a large amount ...
For example, if your local utility burns oil or coal to generate electricity, any efforts you make to reduce usage translates into cleaner air. The Environmental Protection Agency (EPA) encourages local governments to “promote further energy use reductions in the residential sector by promoting ...
