DAI 2
Hello students. Today I'd like 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.
