RENEWABLE ENERGY
Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy sources exist over wide geographical areas, in contrast to other energy sources, wich are concentrated in a limited number of countries.

FOSSIL FUELS
The fossil fuels are the sources of energy that are non renewable and they are pollutants.
There are: the oil, natural gas, the radioactive mineral (uranium) and other minerals as the coal.
Then can be solids, liquids or gases. The solids are coal and uranium. The liquids oil, petrol and the gaseous are butane and natural gas.

THE GREENHOUSE EFFECT
The greenhouse effect is a natural process that occurs when the Sun rays reenter in the Earth’s surface. There is an important part in all this is : water steam, carbon dioxide, methane, nitrous oxide and ozone.
L’efecte hivernacle és un fenomen natural que permet que la Terra tingui una temperatura idònia per a la vida: l’energia del Sol travessa l’atmosfera i escalfa la Terra, però alguns gasos de la atmosfera ( CO2 i vapor d’aigua) impedeixen que la radiació procedent de la Terra sigui escampada per l’espai.

Transformació de l’energia
Energy is transformed into heat or into another types of energy.
For example: The potential energy is transformed into kinetic energy. And kinetic into heat.
L’energia mai s’acaba.
Un exemple pràctic és quan posem una pilota dalt de tot d’una rampa. Llavors tenim energia potencial i quan baixa es converteix en energia cinètica.

We start a new PROJECT!!!
This is the fourth project we participate. Now we are very interested in Sustainable Energy for Everybody.
Com cada projecte, tenim un repte molt diferent a tots els altres: Create a FAKEBOOK for our company!!!!!
Cada grup s’ha convertit en una empresa d’energia RENOVABLE. Cada companyia ha de convéncer a l’Ajuntament de Lleida que la seva energia és la millor. Per això tenim el FAKEBOOK, per penjar-hi totes les coses que vulguem ensenyar o dir.
Així què, comencem, no?!
