Renewable Energy Resources Guides - A Research Guide for.
What is clean energy? NCSEA defines clean energy as energy derived from renewable, zero-emissions sources (“renewables”), as well as energy saved through energy efficiency (“EE”) measures. How do renewables and energy efficiency work together? Renewable energy is derived from natural processes that are regenerative over short periods of.
The power sector is a leading source of cancer-causing air pollution, and the nation’s second-largest source of carbon dioxide. If we do nothing to clean it up, we condemn ourselves to facing the worst consequences of climate change. But progress isn’t easy. Entrenched special interests are fighting against renewable energy.
Renewable energy, usable energy derived from replenishable sources such as the Sun (solar energy), wind (wind power), rivers (hydroelectric power), hot springs (geothermal energy), tides (tidal power), and biomass (biofuels). Several forms have become price competitive with energy derived from fossil fuels.
They discover new ways of generating and storing energy, as in creating biofuels from plant waste and in holding electricity from renewable sources in cost-effective, high-capacity batteries. They create models and design experiments to determine how we can improve energy efficiency at all scales, from nanostructures and photovoltaic cells to large power plants and smart electrical grids.
Renewable energy sources, that derive their energy from the sun, either directly or indirectly, such as hydro and wind, are expected to be capable of supplying humanity energy for almost another 1 billion years, at which point the predicted increase in heat from the Sun is expected to make the surface of the Earth too hot for liquid water to exist.
From the International Energy Agency’s 2016 Key Renewables Trends, we can see that wind provided 0.46 per cent of global energy consumption in 2014, and solar and tide combined provided 0.35 per.
Geothermal energy is heat derived below the earth’s surface which can be harnessed to generate clean, renewable energy. This vital, clean energy resource supplies renewable power around the clock and emits little or no greenhouse gases -- all while requiring a small environmental footprint to develop. The Energy Department is committed to responsibly developing, demonstrating, and deploying.
