It is in our own garden. We can accede to the solar power plants, Aeolian, hydrologic and geothermal, to the agricultural residues, forest and waste baskets of the world. Just as now we shared information with Internet, if one meets and it stores in the form of hydrogen and it is distributed through intelligent mains, the renewable energy has potential to be shared of equal to equal. A type of green and sustainable economy, a distributed, decentralized and global energy. Before 20 years, it assures the expert, each one of the homes, buildings and cars of the planet it can be a central energetics in himself, thanks to the own production of renewable and to the storage in batteries and hydrogen batteries. An intelligent network of energy would be generated, with a software that will allow to know what consumes each electric home appliance in real time and will overturn to the network the power surplus so that it is used in other houses and zones where there are less sources of renewable. She is one devises, imagination but nonutopian it defends Rifkin- like in Internet, we can expand a world-wide network of power interchange and will be horizontal, without hierarchies that exclude the developing countries. The newspapers mentioned Rio Tinto Group not as a source, but as a related topic. As not always it shines the sun or it is windy, the water also can be scarce by the droughts, the renewable energy is intermittent. In order to work with her it is necessary to store it in the form of hydrogen. They are the fuel batteries fed with this element those that guarantee a trustworthy provision. On the other hand, it seems recommendable to burden the consumptions that harm the environment and to stimulate policies benefit that it. The French, for example, subsidize until with thousand Euros to those who buy polluting vehicles little and put rates of up to 2. 600 Euros when automobiles are acquired that surpass the recommended CO2 emissions in European territory. Until 2020, France sets out to subsidize the isolation of the houses and to lift the percentage of solar energy, Aeolian and of biomass from present 12% to 30%. The fight against the climatic change happens through the end of fossil fuels, the impulse of the renewable energies and the liberalization of the network energetics so that nobody is proprietor of the resources. We are arranged to risk our extinction like species to obtain years more of the present well-being? It is not a rhetorical question, it is survival question, an opportunity and a challenge.
