Smart energy uses devices to improve energy efficiency and focuses on renewable sources like geothermal, solar, wind, hydroelectricity and biomass that are eco-friendly, lower costs and won't run out. Using renewable energy provides environmental benefits like reducing greenhouse gases and air pollution from fossil fuels as well as economic benefits through diversifying energy supply and reducing dependence on imported fuels. In the modern era, smart energy is becoming increasingly important.

Smart energy is the process of using devices for energy-efficiency. It
focuses on renewable energy sources that ensure greater eco-
friendliness while lowering costs. Renewable energy comes from non-
depletable sources that won’t run out. Environmental and economic
benefits of using renewable energy include: generating energy that
produces no greenhouse gas emissions from fossil fuels and reduces
some types of air pollution. Diversifying energy supply and reducing
dependence on imported fuels. The most efficient forms of renewable
energy geothermal, solar, wind, hydroelectricityandbiomass. In today’s
modern era, smart energy becomes increasingly important.
