what are the energy types
Although there are many specific types of energy, the two major forms are Kinetic Energy and Potential Energy. Kinetic energy is the energy in moving objects or mass. Wind energy is an example. The molecules of gas within the air, are moving giving them kinetic energy.
Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. These forms of energy can be transferred and transformed between one another. This is of immense benefit to us.
Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean's tides come from the gravitational pull of the moon and the sun upon the Earth. In fact, ocean energy comes from a number of sources. In addition to tidal energy, there's the energy of the ocean's waves, which are driven by both the tides and the winds.
Energy is also transferred from potential energy () to kinetic energy () and then back to potential energy constantly. This is referred to as conservation of energy. In this closed system, energy cannot be created or destroyed; therefore, the initial energy and the final energy will be equal to each other.
They generate much less pollution, both in gathering and production, than nonrenewable sources. 1  Solar energy comes from the sun. 2  Some people use solar panels on their homes to convert sunlight into electricity. 3  Wind turbines, which look like giant windmills, generate electricity.
