The man is always looking for resources to provide

energy.

The most traditional ones are:

Coal.

Oil

But both are dangerous for the environment.

They pollute the atmosphere. Besides, they are non-

renewable sources.

There are two other kinds:

Hydro-electric energy

Nuclear energy

Some experts and environmentalists do not approve

them. Hydro-electric dams can alter the environment and

the life in the rivers and lakes. Nuclear power stations are

not safe and produce dangerous waste.

The renewable sources, also called clean

energies, are the cheapest, safest and most

convenient.

They are:

Solar energy

Wave energy

Wind energy

They do not pollute the environment and are

always available. Most developed countries

use them.
