Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.
People use many sources of energy. Ancient people used only their arms, hands and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the 18th and 19th centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy.
Energy is one of the basic concepts, or ideas, or physics. It is the ability to do work. Without energy we could not live. We need energy to work, and scientists are always looking for new sources of energy.
1.where most of the world's energy from?
2.what did ancient people use before they discover fire?
3.when do people strat using machines?
4.did the first machine use coal?
5.what are scientists trying to look for?

Energy is fundament to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas, with which their life can be improved.
People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps the problem of indoor air pollution. Moreover, it is made from plant waste and animal manure. They cost almost nothing.
The tendency to use renewable energy sources in developing sources in developing countries is on the increase as non-renewable ones are running out. In the future, the wind and the sun will be uses as the most important environmentally friendly energy sources.
