UNIT 10: SOURCES OF ENERGY
A/ READING TEXT
Energy is very important for our daily activities, like using electricity in our homes and powering cars and factories. We use different sources of energy to do this.
One common source of energy is fossil fuels, like coal, oil, and natural gas. These come from the remains of ancient plants and animals. When we burn fossil fuels, they make electricity and heat. But burning them also puts carbon dioxide and other pollutants into the air, which causes climate change and air pollution.
Renewable energy sources are better for the environment. Solar energy comes from the sun. Solar panels capture sunlight and turn it into electricity. Wind energy uses wind turbines to turn wind into power. Hydroelectric power uses flowing water, often from dams, to make electricity. Biomass energy comes from organic materials like wood and crop waste, which can be burned or turned into biofuels.
Nuclear power is another important energy source. It is made by splitting atoms in a process called nuclear fission, which makes a lot of heat. This heat is used to make steam, which drives turbines to produce electricity. Nuclear power does not pollute the air much, but there are concerns about safety and what to do with the waste.
In conclusion, using different sources of energy is important to meet our needs and protect the environment.
