Environmental Benefits

• Solar energy is a renewable resource, meaning that there is no danger of depletion, as is the case for fossil fuels. Solar energy does not emit greenhouse gases, which contribute to global warming. It also is a clean energy source that does not release pollutants, like carbon dioxide or methane, into the atmosphere.
  
  

Maintenance and Versatiliy

• Solar energy units have become increasingly durable and easy to maintain. Solar cells do not contain any moving parts, which greatly reduces maintenance and repairs costs. Solar energy has become more versatile; photovoltaic cells can be used to power small objects, like watches, or entire electric grids, according to the U.S. Department of Energy.
  
  

Cost

• Although solar cells are not inexpensive, long-term savings in use, maintenance and repair costs may compensate for higher initial costs. Federal, state and local government programs, as well as manufacturers and utility companies, may offer tax credits and rebates for solar energy costs.
