The current oil reserve on earth can only meet the demand by human for 46 years, gas and coal can last for only 65 years and 200 years too. Production and life of human depend on Oil-Gas-Coal resource. Meanwhile, mass use of Oil-Gas-Coal resource is the main reason causing the global deterioration of climate and environment.
The renewable energy – Solar Energy is a effective substitute of Oil-Gas-Coal resource to solve the problem of energy crisis and environment pollution.
Diagram from Shell oil company shows solar as the future leading source of energy. Even Oil companies realize the FUTURE IS SOLAR.
