Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." [1] [2] Definitions of sustainable energy usually look at its effects on the environment, the economy, and society.
Sustainable energy, such as wind and solar energy, creates zero carbon emissions that can harm the atmosphere and contribute to global warming. It offsets the need for fossil fuels, which are actively increasing climate change and polluting our earth.
What Is Sustainable Energy? Sustainable energy is derived from resources that can maintain current operations without jeopardizing the energy needs or climate of future generations. The most popular sources of sustainable energy, including wind, solar and hydropower, are also renewable.
What is sustainable energy? Sustainable energy refers to the use of any type of energy that can meet demands without putting the resources in danger of running out. Sustainable energy sources cause minimal damage to the environment and will never deplete.
Put simply, sustainable energy is environmentally friendly and renewable. The International Energy Agency states that there are three generations of renewable technologies, reaching back more than 100 years. According to the IEA’s “Renewables in Global Energy Supply” fact sheet:
This means that sustainable energy is power which is able to be replenished within a human lifetime and so cause no long-term damage to the environment. Sustainable energy includes all renewable energy sources, such as hydroelectricity, biomass, geothermal, wind, wave, tidal and solar energies.
Sustainable energy is energy that is capable of meeting the energy needs of the present without compromising the resources and energy supply of the future. Sustainable energy is the key to the transition to a new energy model, capable of addressing three global challenges: environmental conservation, energy security, and socio-economic development.
Learn more about the advantages of wind energy, solar energy, bioenergy, geothermal energy, hydropower, and marine energy, and how the U.S. Department of Energy is working to modernize the power grid and increase renewable energy production.
The need for sustainable energy that doesn’t disrupt the delicate balance of the Earth’s atmosphere may be the most important issue facing this generation. Explore trends and advances shaping the future of energy.
Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels. In any discussion about climate change, renewable energy...
