There are many types of energy sources. In a world where the instability of both society and nature is increasing, the issue of energy is a hot issue of great concern. Fossil energy sources, which have been considered as the main source of energy, are gradually becoming scarce and are also the cause of many immobility and disputes between countries around the world. The following energy sources are available: Nuclear Energy, Compressed Natural Gas; Biomass energy; Geothermal energy. Meanwhile, as scientists predict, with the current rate of exploitation and use of fossil resources, within a few centuries our descendants will have to bear serious consequences. Since then, the need for alternative energy sources has become more and more urgent, and more and more alternative energy research projects have been started and developed. However, not 100% of them are suitable for future development.

  Energy is very important in our daily life. We use energy for almost everything we do. However energy is limited. We should do the following things to save energy. Firstly, we should use electricity more efficiently. Secondly, we had better reduce our electricity bills. Besides, it’s necessary to turn off the lights when leaving a room or before going to bed to save energy. Moreover, we ought to reduce the use of fossil fuels. In short, we should try our best to save energy for our future and for our planet’s future.

Renewable energy describes a collection of energy technologies i.e. solar, wind, geothermal derived from sources that are never-ending and can be replenished time after time. Most countries across the world heavily depend on fossil fuels (oil, coal andnatural gas) as sources of energy to power their economies.

Fossil fuels are non-renewable forms of energy, meaning, they utilize limited resources that will ultimately deplete, hence, driving up overall energy costs. These very countries have responded to the threat by stepping up campaigns to embrace renewable forms of energy like solar and wind

People can save energy by many ways:

1. Turn off the lights,televisions,.... when we aren't using them

2. Use low energy light bulbs

3.Taking showers instead of baths

4.Don't leave the fridge door open

5.Use public transport

6.Use a hand fan to keep cool in summer
