Essay about Non-Renewable Energy Resources
This Project will be in two Parts. The first part is about
Non-renewable energy. Non-renewable energy is a resource that will some day we will run out of. Non-renewable energy is a resource that will some day we will run out of.
The second part is on Renewable energy. Renewable energy is a resource that we will never run out of because it is continually being replaced. The sun is the source of all our energy resources. The sun's energy reaches Earth and is converted into many forms , which we then use to supply our energy demand.
Non Renewable Energy Resources
COAL. One of the most important natural fuels, coal was formed from plant life buried in the Earth millions of years ago. Like …show more content…
There are two ways which nuclear energy is released by human intervention. The first makes use of elements with very heavy atoms, such as uranium. More energy is required to hold together the uranium nucleus than to hold together two nuclei that are half the size of a uranium nucleus.
In atom bombs and in fission reactors, free neutrons bombard uranium atoms. When a neutron hits a nucleus, the nucleus splits into two smaller nuclei, releasing a great deal of energy. In the reaction, some of the neutrons of the uranium nucleus fly off and hit other nuclei, causing them to split in two and release more energy and more neutrons. The process can continue explosively unless metal rods are inserted in the middle of the uranium to capture some of the neutrons and slow down the reaction. This sort of reaction is called a fission reaction because in it nuclei are broken apart.
The second kind of nuclear reaction is harder to produce and control.
It makes use of the fact that very small nuclei, such as hydrogen and its isotopes, require slightly more energy per proton and neutron to exist than do somewhat heavier nuclei. (The situation is exactly opposite to that of the uranium nucleus, where the lighter
