Renewable clean power that is available every day of the year, even cloudy days produce some power. Return on investment unlike paying for utility bills.
Why solar energy is bad?
Solar energy systems/power plants do not produce air pollution or greenhouse gases . ... Some solar thermal systems use potentially hazardous fluids to transfer heat. Leaks of these materials could be harmful to the environment. U.S. environmental laws regulate the use and disposal of these types of materials.
Is solar energy the future?
In 2018, solar generated about 1.5% of US electricity. Of all renewable energy generation, solar PV is expected to grow the fastest from now to 2050 . Some solar-heavy grids, such as the California Independent System Operator have experienced times where over half of demand was met by solar PV.
Is coal nonrenewable or renewable?
Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
