Pros & Cons Of Nonrenewable Energy Sources
There are reasons for both using nonrenewable energy sources, such as fossil fuels, and for making a timely change in energy infrastructure to phase out their use. The reliability of energy derived from nonrenewable resources has provided an abundance of electricity and transportation for contemporary industrial nations, but concerns over the safety and sustainability of these power systems have also arisen.
The Difference Between Renewable and Nonrenewable Energy Sources
The main difference between renewable and nonrenewable energy is within the combustion and consumption of fuel. Nonrenewable energy sources burn oil and petroleum products similar to gasoline, diesel fuel and propane to power a motor or electrical generator. Natural gas can be burned for heat and electricity, as is coal. Uranium ore is mined to be used as fuel in fission reactors. All petroleum refinery process ppt india of most of these energy depend on fuels which are in finite supply. Alternatively, renewable energy sources equivalent to solar, wind, water and geothermal all depend on collecting and converting the energy from naturally occurring phenomena which might be relatively permanent and require no external fuel source.
Positive Aspects of Nonrenewable Energy
The energy infrastructure of much of the industrialized world is built to be powered by fossil fuel. According to Andy Darvill’s Science Site, nonrenewable fossil fuels provide 66 percent of the world’s electrical power, while satisfying 95 percent of our total energy needs. These include heating, transportation and electricity generation. This pre-existing infrastructure makes the use of fossil fuels much easier to adopt than renewable options, which require a greater initial investment. Photovoltaic solar cells or windmills, for instance, may require substantial amounts of money to install. But an existing building can draw energy from an electrical grid and current natural gas pipelines without any new equipment. Nonrenewable energy sources are also able to generate a more constant supply of power, as long as their fuel exists. Renewable energy sources may depend on irregular or less frequent conditions, equivalent to sunlight to generate solar power or petroleum refinery process ppt india wind to turn turbines.
Negative Impact of Nonrenewable Energy
One long-term concern with the usage of nonrenewable resources is their lack of sustainability. Eventually, these limited resources will either run out or become too difficult to mine and our energy infrastructure will lack needed fuel sources. Of more imminent concern is the pollution generated by mining, refining and consuming these fuel sources. Harmful levels of air pollution are generated by coal power plants and power derived from burning petroleum products. Another concern in using these kind of fuels is the potential for accidents, which might devastate both human life and the environment. While relatively rare, the outcomes of an accident in a coal mine, on an oil rig or at a nuclear reactor are very severe.
