Some improtant sciemtific problems for development of renewable and new energy——The only way for development of non-fossil energy

Along with the progress of high technology and the rapid development of economy, the demand for non-renewable is energy growing very fast.It has caused serious environmental pollution and the exhaustion of resources.Based on the energy security and environment endurance, we must adjust the configuration of energy consumption.We should make great efforts to develop and use the renewable energy and new energy, meanwhile to widely use fossil energy.Renewable energy sources mainly include solar energy, wind energy, bioenergy, ocean energy and hydrogen energy.And new energy sources are mainly geothermal energy, gas hydrates and nuclear power.We predicat that the proportion of renewable energy, currently about 3%, will be up more than 40% in 2050, and the proportion of fossil energy will decreasefrom the current 80% to 50% in 2050.In the use of energy in the future, we should also pay attention to ecological balance, environmental pollution, global warming, melting glaciers and building good life and living space.
