A few nonconventional forms of energy include solar energy, geothermal energy, wind energy and hydroelectric energy. Each form of energy has its advantages and disadvantages. Nonconventional forms of energy, also referred to as alternative energy resources, are sought after to reduce pollutants and toxins that are released into the environment from conventional energy production.
Solar energy is a renewable resource and lasts as long as the sun is shining and generating heat. However, the fact that it is dependent upon the sun makes it a less advantageous form of energy for those living in regions with frequently cloudy weather.
Geothermal energy has the potential to be very environmentally friendly, as it produces no harmful by-products if produced correctly. However, flaws in its production can produce pollutants, and improper drilling techniques release hazardous chemicals from the Earth.
Wind energy is renewable. However, wind power is intermittent, and it is necessary for a continuous stream to form in order to produce efficient energy. Hydroelectric energy is virtually hazard-free, as there are no chemicals required to produce it. It is also a very renewable resource as the water used to generate power can be used again. The major drawback to hydroelectric energy is the cost involved in building the facility to produce it. Dams where the energy is generated are expensive to build.
