Which are renewables: wood, uranium, trash (as fuel), coal, wind, natural gas, hydroelectric?
Write any two sources of electrical energy.
Renewable energy resources are those that can be replaced in a short time. Solar energy and wind energy, for instance, are renewed constantly by the sun and wind. Solar energy can be collected in large panels called solar cells, which collect sunlight and convert it into electrical or thermal energy. Wind energy is caused by the uneven heating of the Earth's surface. The kinetic power of wind can be used to turn windmills, which can then be used to generate electricity. Water energy is really a form of gravitational potential energy collected by storing water in a reservoir behind a dam. As the water falls through a pipe, its potential energy is converted into kinetic energy and used to turn a turbine. The turbine produces a stream of electrons or electrical energy called hydroelectric power. Geothermal energy is energy that comes from the heat found inside Earth's crust. Like the sun, nuclear reactions deep inside the Earth generate thermal energy. Where it can be found close to the surface of the crust, geothermal energy is almost unlimited; however, it is only found at thin points in the crust, in areas prone to volcanoes and earthquakes. Which of the following describes geothermal energy in use? A A drought in recent years has lowered the amount of hydroelectric power produced by the Hoover Dam. B The wide open land and strong gusts of the Greater Accra region in Ghana make it a perfect location for multiple turbines. C Iceland is situated on top of multiple volcanoes and harnesses this natural power to heat the roads and sidewalks in the winter. D Innovators are working to create panels to replace asphalt on highways, so roadways can generate energy from the sun even as cars burn fossil fuels.
