What is energy Energy is the ability to do work. You can do work only if you have the energy . Energy is needed all the time- to work machines in factories, gadgets at home, vehicles on the road, planes in the air and so on. Living things are also using energy all the time.

Different kinds of Energy Fossil fuel energy: Fossils are the remains of animals or plants which died millions of years ago. Dead animals and plants got squeezed and pressed under layers of rock. They slowly changed into coal, crude oil and natural gas. All these are found underground. They are called fossil fuels. When you burn fossil fuels you get energy.

Solar Energy: Energy from sun is called Solar Energy. Solar energy can also be used to produce electricity.

Wind Energy: Energy form the wind is called wind energy. It is used to move the fan on a windmill to produce electricity.

Chemical Energy: There is energy stored inside a battery. This is called chemical energy. Since batteries contain chemicals, batteries have to be used carefully. Used batteries, when thrown away, can also pollute land and water.

Electrical Energy: Electrical energy is also made in a thermal power plant using fossil fuels. You already know that using fossil fuels has many problems.

Energy from the falling water: A dam is a huge wall which blocks a flowing river. A dam has a gates. When the gates are opened , the water rushes down like a giant waterfall. It is used to make electricity.

Atomic Energy: Energy form the atom is called atomic energy. It is produced in nuclear or atomic plants.This kind of energy can be very dangerous to produce and use.
