Cavriago A (RE) climbed into the chair Energy

's dedicated to energy saving and renewable energy the first appointment of the exhibition "science culture and environment", Environment and Sustainable Development organized by the Municipality of Cavriago. The meeting was held last Thursday, addressed to Prof. Paul Erman, President of the EAAP (Alternative Projects for Energy and Environment).
The theme that we wanted to address is the most discussed worldwide, as well as more difficult to solve in the short to medium term. The question can be summed up in one concept, born of no more than a decade ago, which is that of ecological footprint. The ecological footprint of a system is the per capita area of \u200b\u200bproductive land that can be exploited in a sustainable manner, ie without its progressive collapse. In the Earth's ecological footprint was estimated to be on average about 1.8 hectares per capita. An Italian leverages local resources to approximately 3.8 hectares, ie about twice faster than the natural rhythms would impose. For countries like the United States is about 9.4 hectares per capita, while for India of 0.5 hectares, a figure in rapid and constant growth. On balance, the hunger for resources the world far exceeds the ability to regenerate, and these trends show a rapid deterioration of this relationship.
The situation becomes even more serious if we highlight the now demonstrated that there is close correlation between the consumption of energy from fossil fuels and climate change taking place in the atmosphere. This without considering the problems and tensions of economic and geopolitical these sources generate. What
then the possible answers? According Ermani pass all the answers to a common point, which is that of reducing energy consumption by reducing waste and increasing efficiency in the processes of use.
The technique has developed several solutions that can exploit renewables for power generation. They range from the photovoltaic solar energy, through wind and hydropower. There are even showers and ovens and solar-powered irrigation systems.
The energy that these technologies can provide, in addition to not be sufficient to satisfy the hunger that the world currently has, not even remotely compete with what can be achieved by saving technologies. The "negawattora" is the energy source on which, immediately, we need to focus.
on this front, the points of action are different. First of all you need to intervene on behaviors that we all assume to use the energy. There is also a building "intelligent" able to reduce by 50% and over consumption of heating and cooling of housing than the average home. There are so-called micro-distributed systems, capable of supplying power and heat yields 2.5 times higher than those of normal power. Appliances that are on the market, with the same performance, reduce fuel consumption by up to three times compared to standard or traditional.
It is basically to make choices. Choices that may or may not have an immediate economic return, which may require a change in our habits, but that does not coincide with a deterioration in the quality of life. On the contrary, seek to preserve it.
