Non Renewable Energy

DONE BY ANWAR

Energy exists freely in nature. Some of them exist infinitely (never run out, called RENEWABLE), the rest have finite amounts (they took millions of years to form, and will run out one day, called NON-RENEWABLE)With this in mind, it is a lot easier to lay any type of energy source in its right place. Let's look at these types of energy in the diagram below:

What is renewable energy? RENEWABLE ENERGY

When its source cannot run out (like the sun) or can easily be replaced (like wood, as we can plant trees to use for energy)

When their sources are carbon neutral. This means they do not produce Carbon compounds (such as other greenhouse gases).

When they do not pollute the environment (air, land or water)

When can energy be called 'Renewable?

RENEWABLE ENERGY

Biomass fuels come from things that once lived: wood products, dried vegetation, crop residues, aquatic plants and even garbage. It is known as 'Natural Material'. Plants used up a lot of the sun's energy to make their own food (photosysnthesis). They stored the foods in the plants in the form of chemical energy. As the plants died, the energy is trapped in the residue. This trapped energy is usually released by burning and can be converted into biomass energy.

Wind is caused by huge convection currents in the Earth's atmosphere, driven by heat energy from the Sun. This means as long as the sun shines, there will be wind.The earth's surface has both land and water. When the sun comes up, the air over the land heats up quicker than that over water. The heated air is lighter and it rises. The cooler air is denser and it falls and replaced the air over the land. In the night the reverse happens. Air over the water is warmer and rises, and is replaced by cooler air from land.

Wind Power RENEWABLE ENERGY

Moving water has kinetic energy. This can be transferred into useful energy in different ways. Hydroelectric power (HEP) schemes store water high up in dams. The water has gravitational potential energy which is released when it falls.

Deep down in the earth's crust, there is molten rock (magma). Molten rock is simply rocks that have melted into liquid form as a result of extreme heat under the earth. This can be found about 1800 miles deep below the surface, but closer to the surface, the rocks layers are hot enough to keep water and air spaces there at a temperature of about 50-60 degrees F (10-16 degrees C). Geothermal technology takes advantage of the hot close-to-earth-surface temperatures to generate power.

What is non-renewable energy?

Coal is a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons. Coal is made of the remains of ancient trees and plants that grew in great swampy jungles in warm, moist climates hundreds of millions of years ago. The chemical and organic process these dead organisms undergo to become coal is known as Carbonization. Coal is ranked very high if it has undergone a longer carbonization period. An example is Anthracite. Coal that has not undergone too much carbonization is ranked low, and an example is Peat.

rude oil (a non-renewable resource) is usually found in underground areas called reservoirs. It is liquid in nature and yellowish black in colour. They are composed mainly of hydrocarbons and organic compounds. They are usually discovered by oil prospecting scientists. Sometimes, petroleum and crude oil are used to mean the same thing, but petroleum itself is a broad range of petroleum products including crude oil itself.

Petroleum (Crude Oil)

NON-RENEWABLE

ENERGY

Natural Gas is colorless, shapeless, and odorless in its pure form. Unlike other fossil fuels, natural gas is clean burning and emits lower levels of potentially harmful byproducts into the air. It is therefore called "Clean Gas'.bonds in chemical energy While natural gas is formed primarily of methane, it can also include ethane, propane, butane and pentane. It is one of the gases that are formed by the same formation of fossil fuels.

Propane

Propane is an energy-rich gas. Its chemical formula is C3H8. It is one of the liquefied petroleum gases (LPGs) that are found mixed with natural gas and oil. Propane and other liquefied gases, including ethane and butane, are separated from natural gas at natural gas processing plants, or from crude oil at refineries. The amount of propane produced from natural gas and from oil is roughly equal.

Uranium (Nuclear Energy)

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.It is usually in a form of heavy metal, naturally occurring in most rocks, soil, and even in the ocean! It is found in many places in the world. Energy from uranium is called nuclear energy.
