Description

Energia regenerabila este energia care provine din resursele naturale cum ar fi lumina soarelui, vantul, ploaia, mareele, si caldura geotermala, toate acestea fiind regenerate automat (pe cale naturala). In 2008, circa 19% din consumul total de energie al planetei a provenit din energiile regenerabile, grosul de 13% fiind obtinut din biomasa traditionala, care a fost utilizata in principal pentru incalzire, iar 3.2% a provenit din hidroelectricitate. Restul de 2,7% a fost obtinut prin metode moderne ca (micro hidrocentrale, biomasa moderna, vant, soare, geotermal, biocombustibili, etc), dar toate aceste energii regenerabile moderne sunt intr-o permanenta si rapida crestere. In cadrul energiei globale, cea electrica reprezinta circa 18%, fiind obtinuta in principal prin hidrocentrale (15%), iar restul de 3% prin noile energii regenerabile. Aceasta carte doreste sa propuna noi metode de obtinere a energiilor regenerabile. Dupa 1950 au inceput sa apara uzine nucleare pe fisiune. Energia de fisiune nucleara a reprezentat un rau necesar. Ea a reusit sa lungeasca viata petrolului si sa previna o criza energetica globala foarte grava. Chiar si asa, energia obtinuta din hidrocarburi (petrol, carbune, gaze, biomasa) reprezinta aproximativ 66% din totalul de energie produsa si utilizata astazi la nivel mondial. Daca mentinem acest nivel de productie si consum petrolul se va epuiza in circa 40 ani. Pe de alta parte, astazi, productia de energie nucleara (superioara), bazata pe fuziune nucleara, nu este inca perfect pusa la punct (desi studiile se afla intr-un stadiu foarte avansat). Insa timpul trece repede. Trebuie sa ne grabim sa implementam si sa dezvoltam noile energii regenerabile deja cunoscute, dar si noi posibile energii regenerabile. In aceste conditii, prezenta lucrare vine sa propuna noi posibile surse de energii regenerabile.
