Offshore Wind Turbines with Yuxin Wu

Wind turbines are a method of energy conversion. They take one form of energy — kinetic energy from wind — and transform it, through a series of mechanical processes, into electricity. Wind energy is considered renewable because it occurs naturally in the world around us. Earth will never run out of wind.

Sustainable Biofuel with Yuxin Wu

Bioenergy is a form of energy produced through the conversion of biomass. Biomass is living organic matter that contains chemical energy captured during photosynthesis. When burned, biomass releases energy in the form of heat, which can be used to heat buildings or generate electricity. Alternatively, biomass can be converted into fuel or gas to be burned for energy at a later time.
