The primary sources of energy in the environment include fuels like coal, oil, natural gas, uranium, and biomass. All primary source fuels except biomass are non- renewable. Primary sources also include renewable sources such as sunlight, wind, moving water, and geothermal energy. There are 6 more fundamental concepts. banh

The main source of energy at present is fossil fuel.

Some alternative sources of energy are wave energy, solar energy, biofuels, natural gas, geothermal power, wind energy, biomass energy, tidal energy, hydrogen gas, etc.

Their advantages are that they are renewable and is most likely to never run out. Also, they are easier to find than fossil fuels. They produce little or no waste that is harmful to the environment like carbon dioxide or methane so they are more environmentally friendly. Their disadvantages are that they don't produce as much energy/electricity as fossil fuels. Another disadvantage is that they rely on their surrounding. For example, wind energy needs to be generated at a windy location and needs wind turbines that take up a lot of space or solar energy needs to be generated at a sunny area and needs lots of solar panels.

We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuels. The amount of fossil fuels in the world is limited. Therefore, we must save it, and at the same time we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, the wave, and the water. These sources are not only unlimited and available but also clean and safe to the environment....

We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuels. The amount of fossil fuels in the world is limited. Therefore, we must save it, and at the same time we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, the wave, and the water. These sources are not only unlimited and available but also clean and safe to the environment. People should develop and use them more and more in the future.                                                                                                    

1. What do we need energy for?                                                                                                                                                 →                                                                                                                                                                       

2. What is our major source of energy?                                                                                              →                                                                                                                             

3. Why must we save fossil fuels?                                                                                                 →                                                                                                                                                    4. What are the advantages of the other alternative sources of energy?                                       →                                                                                                                                   5.

Read the passage and tick true (T) or false (F).Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily...

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question Nonrenewable energy source is an energy source that can be replenished in a short period of time and renewable energy source is an energy source that we are using up and cannot recreate in a short period of time.
