Power lines - Out of every power plant come four wires: the three phases of power being produced simultaneously plus a neutral or ground common to all three. (Read How Power Distribution Grids Work to learn more about power line transmission.) Outflow - Used water is carried through pipelines...
The way light bends when it goes from air to a different material (such as water or glass) is called refraction. (For a full explanation of how it works, please see our detailed article on light.) Refraction is the key to how lenses work—and lenses are the key to binoculars, ...

Members get credits on their electric bills for the power produced. The largest solar farm in Scotland, Errol Estate, is an excellent example of this concept. This farm powers homes at night with stored energy, making it easier and cheaper to use clean energy daily. ...
Moving electrons have energy. As the electrons move from one point to another, they can do work. In an incandescent light bulb, for example, the energy of the electrons is used to create heat, and the heat in turn creates light. In an electric motor, the energy in the electrons creates...
For example, if your brother is old enough not to play with his plastic bike, why not give it to another family who has a little kid so that they don't need to buy one? And one less large plastic toy doesn’t need to be produced. Recycling has never been easier. Many organizations...
