Clean Technologies Example

The Clean technologies, also known as environmentally friendly, are what are used as sources of electricity generation and movement Y they do not produce or they produce very few polluting residues. They are the most environmentally friendly energies.

The power generation, which feed cities and vehicles, since the 18th century they have been verylinked to fossil fuels and derived from coal. These fuels produce a lot of waste pollutants and greenhouse gases.

Starting in the last decades of the 20th century, efforts have been made to reduce polluting emissions, to avoid serious problems such as destruction of the ozone layer and global warming, and the energy industry and transport are among the main emitters of pollutants.

The Clean technologiesarise as the search to apply new scientific and technological knowledge to find energy sources that do not produce waste, or that they produce very few, and are compatible with the conservation of the environment.

Some of these energies can be renewable

, such as those derived from biological products, some non-renewable, such as natural gas, and some others are considered inexhaustible, since, under certain circumstances, especially geographical, they are always available.

Examples of clean technologies:

Solar energy

Solar energy is considered an inexhaustible source of energy. Sunlight is converted by a photosensitive panel into electricity, which can be stored in accumulators or batteries, to be used during nights or days with little radiation solar. The facilities dedicated to the generation of photovoltaic energy are called solar farms. Many industries and cities have sought to create energy autonomy through the use of solar cells on the roofs of houses and buildings.

Wind power

Wind energy is that generated by the wind. In areas where climatic conditions cause constant wind conditions, the installation of wind farms composed of generators with large propellers, as an alternative for the generation of Energy.

Hydraulic energy

The hydraulic energy is that generated from water and gravity. This modality takes advantage of the natural fall of the water through gravity, as are the natural waterfalls and the creation of dams to contain the water and regulate its exit by moving the generators.

Tidal and wave energy

These forms of power generation seek to take advantage of seawater as an energy generator. Tidal energy takes advantage of increases in the water level, caused by the gravitational attraction of the moon that causes the tides. Wave energy is the force provided by the back and forth movement of waves, of which there are already many advances for its use as an energy source.

Geothermal energy

This energy is produced by the internal heat of the earth, which heats natural or created currents of water that is converted into steam, which move the generators.

Natural gas

This is the least clean source, since it produces carbon dioxide residues from combustion; however, many consider it within the category of clean energy, since it has a complete combustion. This is an option especially applied in cars.

Biomass

Another source that also produces some waste product of combustion, are the obtained from organic waste, especially plant waste. From these can be produced ethyl alcohol (ethanol) used as a substitute for gasoline for automobiles, or methane gas, which also has a more complete combustion, as a generator of Energy.

Mercury and lead free products

Lead and mercury are two heavy metals that damage human health, and can also contaminate animals, which are then consumed by humans. New technologies have eliminated these elements from cells, batteries and other products.
