It is good to know that 8% of the total carbon dioxide emissions is attributed to the housing. According to ceroCO2.org each House produces 1,300 kg of CO2 a year. Transport is responsible for 40%. In a housing that applies the criteria of sustainability could reduce is emissions up to 50% without having to make special investments, enough to assume our greater personal responsibility and changing habits grade. In summary, if we do a little sacrifice from our homes and fully assume our responsibility as suggested by the Kyoto Treaty, the gain would greatly considerable.

We are thousands of millions of households. No serian only a change of attitude in the habits of consumption of electricity, natural disasters we are living as worrying. Coal is used to provide more than 50% of the electricity in the United States.UU, just a 500 MW coal plant produces enough electricity for a city of 140,000 people. Burns 1 430,000 tons of coal per year!. Then if an American requests or consumes more power, is requesting more burning coal. It is an American but thousand, millions of Americans, how many thousands of tons of coal and coal sheds CO2 and this is the culprit for the greenhouse effect and thus global warming and phenomena that we are living. Is there a solution? Clear that Yes.

The use of clean technology and the commitment of our responsibility for the dioxide of carbon (CO2) emissions. Only a central power plant, but also the series of small installations of energy production is not all those linked to the electricity networks. Here is where comes increasing relief that these networks can be connected with systems of distributed generation from solar energy either thermal or electric. Here is where it enters as save the world clean technology, i.e. the photovoltaic (PV), solar cells, solar panels, that come to mind when solar energy is mentioned, and convert solar radiation into electricity or thermal solar collector converts solar radiation into heat which can be used to heat water for the household chores or heat from a house in the form of radiant heat. Then finally, worth it start producing our own solar panel, truth?. Today, this is not a secret.
