Renewable Energy

Only few decades ago, humanity started to intensive utilization of the big energetic power of the organic natural fossil resources seamed in the prehistory, in forms of coat, petroleum, methane. The consumption of those fossil resources (created in millions years of sun lighting) is growing so fast that the caused emissions can not be soaked by the earth ecosystem anymore. To give you an example, the carbon cycle (a fundamental element of Life) modifies his balance, increasing the percentage of carbon dioxide in the atmosphere. The results of these events are: Greenhouse effect, weather changes, Ozone reducing in the troposphere; they are bad for human and all living organisms health, because they are too much quick for the biologic evolution. Our daily living (evolved in a short time, from the end of world war II until today) is trigging non-reversible events, that can threaten the survive of human race, and the time to change this trend will be expire in only one generation.
These reasons and the lack of alternatives to preserve balances in the ecosystem in a reliable way (balances that are essential for the survive of human race) are promoting the actual energetic model based on exploitation of fossil energy sources with a sustainable model based on renewable energy sources, and pellets is certainly one of them.
