Today, if we did not account the traditional biomass, a bit more than 87% of the consumed primary energy in the world comes from fossil fuels.
The renewable energies provide less than 2% of the total.
Still counting on an important advance of the renewable energies and the bio combustibles is a preview that towards 2030 fossil fuels still will represent near 80% of the primary energy world-wide consumed.
In the absence of a fast and spectacular technological revolution, the fossil fuel consumption will continue decreasing in relative terms, will continue increasing in absolute terms.

This speech must be corrected and be extended by a egocentric and social perspective, assuming a interactions in the understanding of the nature involving the natural and social ecosystem.
