The car of the

human society,

like the car of the

nature, needs

energy to work,

that is for the

production of

goods, of

services, heating,

illumination, etc..

The energy, easily

available and always

consumed in large

measure, doesn’t bring

comfort to our way of

living; it also involves

an alteration of the

environment on

planetary scale.

exclusively from the

fossil fuels, that furnish

energy through the

process of combustion,

with the formation of

carbonic anhydride that

is responsible of the

For every produced kWh 250 grams of Combustible Oil are saved

You avoids the production of 0,75 Kg of carbonic anhydride for kWh
