ENERGY ISSUES Biomass Materials such as wood, animal waste, and crops are called biomass. These materials can be burned to generate energy for human consumption. Coal Energy Coal is a fossil fuel that is commonly used in producing energy. Conserving Energy Many scientists feel that conservation of current energy resources, not the development of new energy sources, will be the method of the future. Energy Efficiency The rise in use of energy resources has led people to
try to use energy in a more efficient manner. Energy Recovery One of the problems with current energy usage is that it is highly inefficient and vast quantities of energy are wasted. Geothermal Energy Geothermal energy seeks to generate power from the high temperatures below the Earth's surface. Hydroelectric Power
Water, like wind, has been used to do work throughout history. Interest in using hydroelectric power was sparked largely by the desire for a new source of energy. Nuclear Fission Nuclear fission is being used in nuclear power plants to generate substantial amounts of power. However, there are dangers to using it and it won't be possible to use it forever. Nuclear Fusion
Nuclear fusion is an alternative energy source of tremendous potential. If properly developed, it could solve all of the world's energy problems. Photovoltaics The energy of the sun can be acquired through solar energy panels, but Photovoltaics provide another option. Solar Power Solar power is an extremely clean and renewable form of energy that comes from the sun. The Energy Path to the Future Many people have different views concerning the future of energy usage, and the current path is uncertain. Wind Energy Wind power has been used at least since 600 BC. The energy source has become popular in the search for a clean and renewable energy source. |
