I. Fill in the blanks with the words in the box.

 1. …………….energy comes from the heat of the sun.

2. ……………….can be produced by dead plants and animals as they decay.

3. …………………..is often found in the ground, consisting mainly of methane (CH4)

4. …………………energy is energy that comes from the force of moving water.

5. ……………… is flammable black hard rock, used ass a fossil fuel.

6. ………………., commonly known as petroleum, is the largest source of energy in the US.

7. To produce……………………energy, atoms are split apart, which releases energy.

8. ……………….energy is produced from moving air with the help of large turbines.

Read the passage and check (ü) whether the following statements are 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 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: Most of our energy we use every day comes from renewable energy sources.

A. True

B. False
