563050570-1 How can alternative sources of energy be harnessed effectively? Our modern life today needs energy. World energy demand is more than available energy sources. Fossil fuels are running out every time it is used. So we need to provide new energy that can be harnessed instead of fossil fuel for today and tomorrow. Alternative energy This problem can be solved by LCOE‚ national grid‚ and new technologies like Crystal Solar and optimizing battery storage. Fossil fuel is non-renewable energy that

Warming and Alternative Energy People are inflicting major damage to the Earth’s environment‚ and if we don’t do anything to stop the destruction soon‚ the results could be devastating. Most people know about global warming and think it may be a serious problem in the future. What most people don’t understand is that global warming is happening now‚ and we are already feeling some of its destructive power. Because of the dangerous effects of global warming‚ alternative energy sources need to be aggressively
