Alternative energy sources are sources of energy other than fossil fuels. There are three different fossil fuels: coal, oil, and natural gas. Alternative energy sources are being developed to combat concerns regarding the effect on the environment, efficiency, and other issues related to the use of fossil fuels. The definition of what is considered an alternative source of energy has changed over time but generally speaking, an alternative source of energy is produced so that it can be recovered, reproduced, and without emitting high levels of carbon dioxide.
There are a number of different types of sources of alternative energy. There is solar power, wind, hydroelectric, biomass, ethanol biofuels, hydrogen, and geothermal. Solar energy can be used in cooling, electrical, and heating power plants. Currently, solar energy is seen as a viable method of creating energy.
However, innovations and improvements must be made to improve the efficiency and decrease the cost of harnessing solar power. Wind energy was in theory developed by NASA in the 1970’s and is seen as a viable option for creating an alternative source of energy, especially in Europe where initiatives have been made and turbine fields have been created. Ethanol biofuels are a very popular source of creating renewable energy, and recent research has been done to find better types of ethanol than the traditional corn produced ethanol.
Geothermal is considered a viable source of alternative power because it harnesses thermal energy created and stored in the earth. This energy is sustainable and is constantly being replenished. Hydrogen is a source of alternative energy that is being highly considered as a viable option in the future. Over $1 billion has been spent on hydrogen research by the federal government.
Alexander Potoczak of Ohio is very interested in and knowledgeable about alternative sources of creating energy.
