Sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their energy needs and will never be used up or depleted. Some examples of renewable energy sources are solar, wind, hydropower, geothermal, and biofuels. These types of energy sources are different from fossil fuels, such as coal, oil, and natural gas which are finite and polluting.
Is sustainable energy the same as renewable energy?
Sustainable Energy is one which is able to meet the growing demand of today's people without compromising the demand of the people that would require it in future. All renewable energy sources like solar, wind, geothermal, hydropower, wave, tidal power and energy efficiency are forms of sustainable energy. Renewable energy sources have low environmental impact, are widely available to be harnessed and naturally replenished.
Why is sustainable energy important?
Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, become too expensive or environmentally damaging to extract and use. In contrast, the many types of renewable energy resources-such as wind and solar energy-are constantly replenished and will never run out.
