Source of Energy - SS3 Physics Lesson Note
There are many sources of energy, including:
Fossil fuels: Coal, oil, and natural gas are the most common fossil fuels used for energy production. These fuels are formed from the remains of ancient plants and animals and are burned to generate heat and electricity.
Nuclear energy: nuclear power plants use the process of nuclear fission to generate heat and electricity. This process involves splitting atoms to release energy.
Renewable energy: Renewable energy sources are derived from natural resources that are replenished over time and do not deplete, such as wind, solar, hydro, geothermal, and biomass.
Biofuels: Biofuels are derived from organic matter, such as crops, agricultural waste, and forestry residues, and can be used as a substitute for fossil fuels in transportation and heating.
Hydrogen: Hydrogen can be produced from natural gas or other sources, and can be used as a fuel in fuel cells to generate electricity.
Waste-to-energy: Waste-to-energy technologies convert waste materials, such as municipal solid waste, into energy.
Tidal and wave energy: Tidal and wave energy harness the power of ocean currents and waves to generate electricity.
The choice of energy source depends on a variety of factors, including availability, cost, environmental impact, and technology.
