Types of renewable energy resources include moving water (hydro power, tidal and wave power), thermal gradients in ocean water, biomass, geothermal energy, solar energy, and wind energy.
What is the best alternative to coal?
According to the National Aeronautics and Space Administration (NASA), nuclear power is the most effective substitute to challenge fossil fuels for future energy consumption. Compared to coal, gas, oil, and ethanol, nuclear power produces almost negligible adverse climate effects.
What could be burned instead of coal?
Instead of burning coal, the Wabash River plant chemically transforms it in a process called coal gasification. The Wabash plant mixes coal or petroleum coke, a coal-like residue from oil refineries, with water and pure oxygen and pumps it into a tall tank, where a fiery reaction turns the mixture into a flammable gas.6 дней назад
