II. Read the passage carefully and then do the tasks.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable.

Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution.

On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

A. Decide if the flowing statements are True (T) or False (F)

1.     Non -renewable energy is a source of energy that will eventually run out.

2.      Renewable energy comes from natural sources, like sunlight, wind, water, and heat of the Earth.

3.      Burning fossil fuels is harmful to the environment.

4.      Renewable resources are better for the environment, but they are limited in supply.

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
