ENERGY SOURCES
RENEWABLE
Wind energy
Wind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can convert mechanical power into electricity.
Marine energy
Marine energy – also referred to as ocean energy, ocean power and marine hydrokinetic energy (MHK) – encompasses various means through which energy can be harnessed from our oceans. There are various types of marine energy, including wave, tidal stream, tidal range and offshore wind, as well as ocean thermal, ocean current, run-of-river and salinity.
Solar Energy
Solar energy comes from the sun and can be captured with various technologies, primarily solar panelsSolar energy is the most abundant energy resource on Earth. It can be captured and used in several ways, and as a renewable energy source, is an important part of our clean energy future.
Biomass
Biomass energy is the use of organic material to generate energy. Biomass is just organic matter – think, stuff that’s made in nature – like wood pellets, grass clippings and even dung.
Hydropower energy
Hydropower or hydroelectricity refers to the conversion of energy from flowing water into electricity. It is considered a renewable energy source because the water cycle is constantly renewed by the sun.
Geothermal energy
Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma.
NON RENEWABLE
Coal
Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Layers of dirt and rock covered the plants over millions of years. The resulting pressure and heat turned the plants into the substance we call coal.
Petroleum
Petroleum (from the old Greek petra, meaning stone and oleum meaning oil), also known as crude oil, is a fluid mix of liquid and gaseous hydrocarbons, inorganic chemical elements, and physical impurities.
Nuclear
Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity.
Natural gas
Natural gas is a fossil energy source that formed deep beneath the earth's surface. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4).
