Energy Resources

Energy Resources are sources from which energy can be obtained.

Natural Energy ResourcesEnergy is all around us and manifests itself in many different forms: heat, light, sound, magnetism, gravity, movement, and all life functions. It is everywhere in great abundance. Since the beginning of time, nature has been producing and reproducing energy in quantities so that we could never begin to use it all, not even with the most advanced technology.

Types

• Renewable

• Non-renewable

RenewableRenewable resources are natural resources that can be replenished in a short period of time.

•Solar Energy

•Wind Energy

•Hydroelectric Power

•Geothermal Energy

•Tidal Energy

Solar EnergyEnergy comes from the sun is called Solar Energy.

Solar Panel

A solar panel is a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A photovoltaic module is a packaged, connected assembly of solar cells.

Solar Panel

Wind EnergyEnergy produced by air.

Wind Mill

Wind mill converts the kinetic energy into electric energy.

Hydroelectric Power The production of electrical power through the use of the gravitational force of falling or flowing water.Dams

Geothermal EnergyEarth's internal heat is thermal energy generated from radioactive decay and continual heat loss from Earth's formation.

Tidal EnergyTidal energy, is a form

of hydropower that converts the energy of tides into useful forms of power - mainly electricity.

Nonrenewable

A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

MetallicNonmetallic

MetallicRelating to or resembling metal or metals.Uranium

Nuclear fission uses uranium to create energy.

Nuclear energy is a nonrenewable resource because once the

uranium is used, it is

gone!

NonmetallicFossil fuel

Fossil fuels are formed from the remains of plants and animals that lived and died long ago.

The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. 

Petroleum Natural gas Coalo Peato Ligniteo Anthracite

How these fossil fuels made

Once these resources are used, they gone and earth will take million years

to re-grown.

Petroleum

A fossil fuel, petroleum is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure.

Natural Gas

Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants originally obtained from the sun is stored in the form of carbon in natural gas.

Coal

Is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
