Fossil Fuels
Fossil fuels are formed by natural resources such as an anaerobic decomposition of buried dead organisms that are hundreds of millions of years. These fuels contain a high percentage of carbon and hydrocarbons.
Fossils range from volatile materials with low carbon: hydrogen ratios like methane, to liquid petroleum to nonvolatile materials composed of almost pure carbon like anthracite coral.
Fossil fuels are nonrenewable because they take millions off years to form, and reserves are being depleted much faster then new ones are being formed.
The burning of fossils fuels produces 21.3 billion tons of carbon dioxide a year but it is estimated.

Biomass
Biomass is carbon based and is composed of a mixture of organic molecules containing hydrogen, usually including atoms of oxygen, often nitrogen and also small quantities of other atoms, including, alkali, earth metals, and heavy metals.
Biomass energy is derived from three distinct energy sources: wood, waste, and alcohol fuels. Wood energy is derived both from direct use of harvested wood as a fuel and from wood waste streams.
Waste energy is the second-largest source of biomass energy. Biomass can be converted to other usable forms of energy like methane gas
or transportation fuels like ethanol and bio-diesel. Methane gas is the main ingredient of natural gas. Smelly stuff, like rotting garbage, and agricultural and human waste, release methane gas - also called "landfill gas" or "biogas." Crops like corn and sugar cane can be fermented to produce the transportation fuel, ethanol. Bio-diesel, another transportation fuel, can be produced from left-over food products like vegetable oils and animal fats.

Geothermal
The geothermal gradient is the rate at which the earth’s temperature increases with depth, indicating outward heat flows from a hot interior. Away from tectonic plate boundaries, it is 25-30°C per km of depth in most of the world.

Tidal Power
Sometimes also called tidal energy, is a form of hydropower that converts the energy of tides into electricity or other useful forms of power.
Although not yet widely used, tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power. Historically, tide mills have been used, both in Europe and on the Atlantic coast of North America. The earliest occurrences date from the Middle age’s, or even from Roman times.

Wind Power
Is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ship’s.
Large-scale wind farms are connected to the electric power transmission network; smaller facilities are used to provide electricity to isolated locations. Utility companies increasingly buy back surplus electricity produced by small domestic turbines. Wind energy as a power source is attractive as an alternative to fossil fuels, because it is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions
Liquid Bio-fuel
Liquid fuels derived from plant materials – are entering the market, driven by factors such as oil price spikes and the need for increased energy security.
Bio-ethanol is an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops.
Solar Energy
Solar energy can be captured by wind mills, solar panels ect. Solar panels receive ultraviolet rays from the sun to create electricity.
Nuclear energy:
is released by the splitting (fission) or merging together (fusion) of the nuclei of atom(s).
Nuclear energy was first discovered by French physicist Henry Becquerel in 1896, when he found that photographic plates stored in the dark near uranium were blackened like X-ray plates, which
had been just recently discovered at the time 1895.
