in the future it would be good if society would use more biofuels than fossil fuels as a way of getting the energy we use every day, to heat our homes, drive our cars, and light up our cities. Scientists are also trying to extract the sugars from biomass products and turn them into fuel. Also they are trying to grow energy from food products without putting a dent in the global food market. Another idea that is already being studied and tested is the use of oils derived from sustainably grown algae, the algae is also grown using waste water.
