COMMENT 3:GREEN ENERGIES

 Today we use things that need energy such as appliances, cars. Today we need energy for many things. Its use enables the production and improves the living conditions of the human being, all the changes and or transformations in nature are produced by some type of energy.

Many energies pollute the environment, many animals die or leave because of pollution. Coal and oil are the two most used fossil fuels on the planet and are also the most polluting energies that exist. It is necessary to avoid the use of this type of energy, every time they are doing more things to avoid its use, for example they are manufacturing electric cars.

On the other hand we have green energies. Green energy sources are renewable, inexhaustible or that can be regenerated by natural means. They are also clean energies, which do not pollute and whose use does not imply a deterioration of the environment or contribute to climate change. It comes from non-polluting and environmentally friendly sources of natural energy, such as wind, water or the sun.

In my opinion, we should avoid the use of coal and oil and start using green energy, since this type of energy is safe for people, animals and the environment.We must use only renewable energies to protect our planet and stop using other energies, for example, we must start using electric cars and stop gasoline cars, although the problem is that electric cars are very expensive.
