Energetic principles

Preamble :

The Earth is a spaceship that holds in its shipping the non-renewable fossil energy, which is receiving the only one outside energy: and it is the sun.

The biomass (the wood, the straw, ……) as a result of the concentration of such solar energy, is so renewable source of energy from 1 year (straw) to 20 years (wood).

The wind is a result of the solar energy.

The hydraulic energy is an outcome of the solar energy (evaporation – condensation).

The coal, the petrol and the gas are the outcomes of the solar energy however their period of the renewal spreads over during the hundreds millions of years.

The profound geothermal science does not concern about the renewable energy but mostly about the use of the residual reserves of the initial energies from the creation of the Earth.

The surface geothermal science might be partly comparable to the solar energy (storage the heat in the soil).

Contrary to a recent idea, the solar energy does not just form a ludicrously feeble source compared with the needs:
The quantity of the solar energy received every day by the planet is X-times higher than the total daily consumption by the humans (nuclear, coal, wood, fuel oil, gas, hydraulic, …..)

Did you know :
- Your house can produce more electricity than it consumes ?
- The roof of your factory can become an important source of income ?
- With the heat pump, the total energetic consumption of the pavilion of 170 m² (lighting, heating, cooking, sanitary water) can be decreased by 1000 €/a year ? (based to 2006)
- Wrongly designed bay window is a true chasm of the energy whereas the one well constructed constitutes an important energetic contribution ?
