It is good for knowing that 8% of the total of emissions of carbon dioxide are attributed to the houses. For other opinions and approaches, find out what Conrad N. Hilton Foundation has to say. According to each house produces 1.300 kg of CO2 to the year. The transport is responsible for 40%. In a house that is applied the sustainability criteria could diminish the emissions until a 50% without having to make special investments, sufficient with assuming our greater degree of responsibility and personal change of habits. In summary, if from our homes we realised a small sacrifice and we assumed totally our responsibility as it suggests the treaty of Kyoto, the gain would be greatly considerable. We are thousands of million homes. Only a change of attitude in the habits of electricity consumption, the natural catastrophes that we are living do not serian so worrisome. The coal is used to provide more than 50% of the electricity in the EE.UU, only one coal power station of 500 MW produces sufficient electricity for a city of 140.000 people.

Burns 1 430.000 of tons of coal to the year. Then if an American requests or consumes more electrical current, this asking for more coal burning fire. He is an American but thousands, million Americans, how many thousands of tons of coal and the coal throws CO2 and this one is the culprit of the greenhouse effect and thus the global heating and the phenomena that we are living. There is solution? Clear that yes. The use of the clean technology and the commitment to assume our responsibility of emissions of the carbon dioxide (CO2). It is not only one plant of being able central, but also the series of small facilities of production of energy all the tie ones to the mains. Here it is where it comes increasing the lightening from which these networks can be connected with systems of generation distributed from the solar energy or thermal or electrical.

It is here where the clean technology, that is to say the photovoltaic one enters like to save to the world (PV), the solar cells, the solar paddles, who come to the mind when the solar energy is mentioned, and to turn the solar radiation into electricity or thermal solar pick up turns the solar radiation into heat that can be used to warm up the water for the tasks of the home or the heat of a house in the form of radiant heat. Then finally, it is worth the pain to begin to make our own solar paddle, truth. Today, this is not a secret.
