Interesting figures related to renewable energy published by BBC world whose signature as author is Patricia Luna and the Latin American Society of sustainable development transcribes them on September 26, 2010. Here I try to summarize them for your agile dissemination to our readers. Robbie Lawler shares his opinions and ideas on the topic at hand. In United Kingdom power plants are the most responsible for carbon emissions and produce 170 million tons of CO2 each year a only modern wind turbine could save about 4,000 tonnes of CO2 according to figures from the British Association of wind energy are estimates that the wind medium-sized Park will have paid toll his cost environmental between 3 and 5 months after its entry into operation there are 250 wind in United Kingdom farms 13 of them are marine parks at the end of its useful life, a wind turbine of this type will be produced 47,14 times the energy required to manufacture it. Solar panels produce 16 times the energy required to assemble solar panels in very sunny places they produce 12 times the energy required to assemble in locations away from city wind turbines which are situated in marine parks brings a greater difficulty of Assembly, transportation and installation. The sea is used a firmer foundation and materials are covered with more chemicals to prevent corrosion of the sea. But finally offshore energy is more profitable from the ecological point of view than solar. Offshore energy appears as one less clean renewable energy, surely by the materials used, are used very expensive and rare, such as tellurium or other exotic materials metals and look for much in mines to find them. Also many more chemicals are used and there are more environmental risk. Wind turbines have their environmental impact but it is much less than that may have any technology, from renewables as conventional power generation plants because its lifetime the wind turbines do not consume any fuel and hence fairly reduce polluting emissions once the wind turbine in operation only there are ecological costs if they replace the blades. see you soon.
