Renewable Energy

RENEWABLE ENRGIES

Renewable energies are the base of our future, so the engineers must improve these technical.

In this moment there are many sources of renewable energies but the sources more important are five.

-WIND POWER. This source uses power of the air to produce energy. The mechanism which produces energy is the wind turbine. The air pushes a propeller which it moves a turbine, this turbine move a generator which produce energy.

In the actuality this source of energy produces the neither point five per cent of the renewable energy in the world

The problem of this source is the environment impact on the place where the wind turbines are. Other problem is that the wind turbines are very expensive and it need much space.

-GEOTHERMAL ENERGY. This source uses the hot into of the earth. Into of the earth there are places where the temperature is higher that the temperature of boiling of the water. The engineers use the evaporated water which is in this place, for move turbines.

In the actuality this source of energy produces the one point five per cent of the renewable energy in the world.

The problem of geothermal energy is that it produces little energy and it has expensive infrastructure.

-HYDRAULIC ENERGY. This source uses power which it has the water due to the different of height. The mechanism works same that the wind turbine, but power is produced for the water.

This source is the more used in the actually although it infrastructure produces environment impact on the place where it is done.

In the actuality this source of energy produce the ninety percent of the renewable energy in the world.

-SOLAR ENERGY. This source uses the ray of the sun for extract electrons with much speed from silicon which is in the photovoltaic panels. These electrons are the electricity. A part of photovoltaic panels there are solar collectors which transform the solar energy into thermal energy.

In the actuality this source of energy produce the neither point zero five percent of the renewable energy in the world.

The problem of this source is that the photovoltaic panels and the solar collectors are very expensive.

-BIOMASS. This source uses the photosynthesis of the vegetables for produce energy. For example the biomass can transform the rest of the curt the olives in energy.

In the actuality this source of energy produce the five point five percent of the renewable energy in the world.

The problem of this source is that it needs many vegetable to produce only a little energy.

In conclusion the renewable energy will be the base of the energy in the future and in fact, in the actuality it produces the twenty per cent of energy in the world.
