Prospectives in alternatives

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.

Energy sustainability in the future

To save the planet can be a business of “income-producing”.
This solution seems opportune in a situation of environmental emergency, but insufficient and dangerous, in a long run.
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.
