Besides this investment is refunded through of the sale of electricity and energy. And once again we must remember that, if we rely on traditional sources, you would spend 11.5 to 16.9 tw, which would require thousands more of these plants, with a cost of approximately $ 10 billion, not to mention the tens of billions of dollars more in health, environment and safety. The WWS plan gives the world a new, clean and efficient system of energy rather than an old, dirty and inefficient. Political will our analysis strongly suggest that WWS costs will be competitive with respect to traditional sources. In the meantime, however, certain forms of energies WWS are significantly more expensive than the fossil energy. Some combination of WWS, subsidies and taxes on carbon, will therefore be needed for a while.
A type of premium production Feed-inTariff (FIT) to cover the difference between the cost of generation and the price at the wholesale electricity is especially effective in helping new technologies renewable. Combining the FIT with a so-called auction sale at declining prices, in which the right to sell power to the system is granted to bidders more bass, provides a continuous incentive for developers of WWS to decrease costs. While this happens, the FIT can go is progressively reduced. The FIT have been implanted in large a number of European countries and in some States of EE UU and they have been quite successful in encouraging solar energy in Alemania.Gravar fossil fuels or their use to reflect their environmental damage also makes sense. But, at a minimum, subsidies to fossil energy, such as tax benefits for the exploration and extraction, should be eliminated to level the match. A promotion wrong less desirable alternatives such as agricultural subsidies and the production of biofuels, must end because it delays the implementation of cleaner systems. For its part, appropriate by legislators, policy development must find ways to resist the pressure that will be produced by the currently established energy industries.Finally, each nation must be willing to invest in a solid transmission system and long distance that can transport large amounts of energy of the WWS in remote regions where often is higher, such as in the U.S.
