In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed.

Energy is fundamental 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 solve the problem of indoor air pollution. Moreover, it’s made from plant waste and animal manure. They cost almost nothing.
The tendency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running outệIn the future, the wind and the sun will be used as the most important environmentally friendly energy sources.
