People should promote the source of renewable energy.Humans discovered various sources of energy, which have become an integral part of modern lifestyles. First of all, humans used traditional sources of energy - coal, gas, petroleum, etc., which are limited in quantity as well as harmful to the environment when overused.
The ever-decreasing amount of petrol, diesel, coal, gas, etc. has made us think that we have to find resources for tomorrow's energy needs which are never-ending and our life goes smoothly without any energy crisis. Renewable energy resources are an important step in this direction
Environmental protection will also be possible through this and under global warming we will also be free from the international pressure of more carbon dioxide emissions. Together we will all be successful in finding solutions to our energy-recovery and environment-protection problems shortly.
