Recentry the way to get energy have been thought again. The proces to get energy from sun light is used for bio-mass energy. The old way to get energy is related bio-mass energy. Bio-mass energy is better for the earth than fuel energy. People can get bio-deasel from bio-mass energy. Bio-deasel can replace gasolin.
