Biomass includes the use of food and wood. Energy stored in non-fossil organic materials such as wood, straw, vegetable oils and wastes from the forest, agricultural and industrial sectors. Biomass is one of the most important renewable energy forms and its use in Canada involves both the oldest and the newest of energy technologies.
Biomass is captured from forest industries. To capture energy from biomass is to burn it, to make heat, steam, and electricity.
Fossil Fuels include different types of oil, gas and jet fuel. They are normally ‘natural resources’ and are extracted from the earth itself. Non-renewable resources. Fossil Fuels may also be associated with mineral fuels. The resources may be crushed, burnt, or turned into steam.
Fossil Fuels form from the organic remains of prehistoric plants and animals.
Hydroelectric Energy produces energy through power plants, some such as; Micro-scale, small-scale and “run-of-the-river.” A dam is built to trap water, usually in a valley where there is an existing lake. Water is allowed to flow through tunnels in the dam, to turn turbines and thus drive generators. Notice that the dam is much thicker at the bottom than at the top, because the pressure of the water increases with depth.
Hydro-electric power stations can produce a great deal of power very cheaply.
Nuclear Energy work by thermal nuclear reactors and fast reactors. The thermal ones use a moderator to slow down the neutrons produced by fission. The moderator can be normal water, heavy water, or graphite. The normal water types are the Pressurized Water Reactor and Boiling Water Reactor. Fast reactors don't have a moderator, and therefore cannot be built with a water filled core, so have used liquid metal, usually sodium, as coolant.
Solar Energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar powered electrical generation relies on heat engines and photovoltaic. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, day lighting, solat hot water, solar cooking, and high temperature process heat for industrial purposes. To harvest the solar energy, the most common way is to use solar panels.
Wind energy is energy obtained from moving air. is the conversion of wind energy into a useful form of energy. Some such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships.
The motion results from the heating and cooling of the Earth.
Geothermal Energy is power extracted from heat stored in the earth. Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near tectonic plate bouneries.
This geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface.
