Energy is the ability to do work
162
It can take a variety of forms: mechanical, electrical, chemical, and nuclear
163
Chemical
164
Nuclear
165
To produce any type of energy, the resources of the earth are used
166
The main resources of the earth are fossil fuels such as natural gas, oil, and coal
167
We get most of our energy from these fossil fuels, but this is harmful to the environment
168
Environment
169
Fossil fuels are nonrenewable and cannot be replaced easily
170
Once we use them up, they're gone forever
171
Be gone
172
They are not clean as they pollute water or air
173
In recent years, scientists try to use other types of energy resources
174
Recent
175
Recently
176
They call them clean energy resources because they do not pollute the earth
177
Clean energy is renewable
178
It is made from resources that can be replaced, like wind, water, sunshine, tides, and plants
179
When renewable energy resources are used, the demand for fossil fuels is reduced
180
Reduce
181
Decrease
182
The most common type of clean energy is the solar power
183
Solar energy is produced by the radiation that reaches the earth

People have used the sun as a heat source for thousands of years
187
Iranians, for instance, use special designs and arrangements of windows, balconies and yards to get the most sunshine
188
Different types of materials might also be used in building the houses
189

This keeps people warm during cold seasons and cool during hot days of the year
191
Nowadays, solar energy can be converted into other forms of energy, such as heat and electricity
192
Nowadays
193
Solar energy might be used for heating water and air in homes, buildings, or swimming pools
194

203
Clean energy resources are widely used in many countries to keep cities and villages clean
204
As a result, fewer fossil fuels are consumed each year and they are saved for the future generations
