Green electricity, or green power, is a reference to energy and electricity sourced from renewable energy sources such as wind and water power facilities, which are the most common. Other possible renewable energy sources include geothermal, biogas, and low-impact hydropower sources.
The word “green” is a reference to the fact that utilizing these power sources is more environmentally friendly compared to some of the more traditional power sources such as coal, gas, and nuclear power plants, all of which can cause a severe negative impact on the environment. In other words, green power or green electricity is comparatively cleaner compared to either coal or nuclear power.
The great thing about green electricity is that it sources electricity from renewable sources or sources that are in no danger of being consumed until there is nothing left. So using green energy also seeks the conservation of our natural resources. Also, green energy is also cleaner because it introduces little or minimal pollutants into the environment as a result.
Rather unfortunately, traditional energy sources like coal and gas are the leading causes of air pollution because of the massive amounts of CO2 that they produce. And while nuclear power does not have the same impact on air quality, the generation of nuclear power does result in radioactive waste that needs to be provisioned for in terms of long-term storage. Otherwise, improperly disposed of toxic nuclear waste can seep into the environment, poison water sources, and even poison the land where they have been disposed of.
Green power or green electricity does not have any such impact on the environment because it is “cleaner” and more environmentally friendly.
