Alt Energy
Wind energy is very simply put as the conversion of wind into electricity. The way that the wind is converted is by using large towers with turbine blades attached to them. As the wind blows and rotates the turbine blade that’s when electricity is being created. The electricity is being converted by the rotations of the blades and sending the energy created as electric currents through large conductors to an electric generator. Then from the

Entropy and Pollution - Renewable Energy, the Entropy Solution?
Entropy and Pollution The substances that we as human beings classify as 'pollutants' have always been present on the planet, because the earth is a closed system. The reason that these materials cause a negative impact on the environment, therefore, is not that they exist, but that they have been dispersed throughout the world's ecosystems in a very disordered fashion. To illustrate this, two pollutants of major concern will be considered, carbon dioxide (CO2) and
