Hello everyone, today I'd to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

Thanks ạ

Nowadays, energy is being run out more and more so what should we do to save energy? First, we should use electricity more efficiently. We should turn the light, the television and other electrical appliances off when we are not using them. We can also use low energy light bulbs to save electricity. Second, we should use less private transport. We should travel by bus or train instead of car and motorbike. In addition, we can avoid using cars or motorbikes for short trips. Finally, we should reduce the use of water. Taking showers instead of baths is a good way. Besides, we should turn off the tap when brushing our teeth; this can save 6 liters of water per minute. In conclusion, those ways can save our lives in the future so we should raise our awareness of saving energy
