The solar energy is guaranteed for the next 6,000 million years. The sun has shone in the sky for about five billion years, and it is estimated that still has not reached half of its existence. It is a source of life and origin of other forms of energy that man has used since the dawn of history, and can meet all our needs if we learn how to make a rational manner that continually shed light on planet. It is an inexhaustible energy source, given its magnitude and because its purpose will be the end of life on Earth.
This year, the sun casts on the Earth four thousand times energy than we consume. It would be wise not to try to take advantage, by all means technically possible, this free energy source, clean and renewable, it can definitely get rid of dependence on oil or other unsafe alternatives, or simply contaminants. It should be noted that there are some problems we face and overcome. Apart from the difficulties that would lead to advanced solar energy policy itself must be borne in mind that this power is subject to continuous variations or less abrupt. For example, solar radiation is lower in winter, just when we need it most.
is vital to continuing the development of emerging imaging technology, acumulacióny distribution of solar energy, to create conditions that make it definitely competitive, worldwide.
