Non-renewable Resources, Examples of Nonrenewable Resources
Most non-renewable energy sources are called fossil fuels: coal, oil and natural gas. Carbon is the main element of fossil fuels. All fossil fuels are similarly formed. In these ancient wetlands, plants, algae and plankton grew. They absorbed the sunlight and produced energy through photosynthesis. When they died, organisms dragged to the bottom of the sea or lake. Plants and animals kill with stored energy sources. Over time, the dead plants were crushed under the sea floor and found places on the surface of rock and sedimentary remains.
Coal is a black or brownish rock. We burn coal to generate energy.
Advantages and disadvantages
Coal is a reliable source of energy. You can rely on the sun or rain, day and night, summer and winter, to provide fuel and electricity. Coal is also harmful. When we use coal, coal releases many toxic gases and pollutants into the atmosphere. Coal mining can also cause underground fires burning for decades.
Oil is a liquid fossil fuel. This is also called oil or crude oil. Oil is trapped by underground rock formations. In some places, oil bubbles come off the floor. In LaBrea Tar Pits in Los Angeles, California, large oil pools rise from the ground. The remains of animals imprisoned there thousands of years ago are still preserved as tar!
We’re drilling the world for oil. Some beds are on land and others are under the ocean floor. When oil is below the ocean floor, companies are drilling at sea. They should build an oil rig. Oil platforms are some of the world’s largest man-made structures. We use oil for a lot of things. About half of the world’s oil is converted to gasoline. The rest can be used in liquid products such as nail rubbing alcohol and polish or in shoes, water pipes, crayons, roofing, vitamin capsules and thousands of other products.
Advantages and Disadvantages
There are advantages to drilling for oil. Removal is relatively inexpensive. It is also a reliable and reliable source of energy and money for the local community.
However, burning gasoline is harmful to the environment. It releases dangerous gases and fumes into the air we breathe. If there is a problem with the drilling machines, the oil may explode from the well and fall into the ocean or surrounding soil.
Natural gas is another fossil fuel trapped underground in reservoirs. It consists mostly of methane. You may have smelt methane before. The decomposing material in the dumps releases methane that smells like rotten eggs. We use natural gas for heating and cooking. We rely on natural gas to power the lights, televisions, air conditioners and kitchen appliances in our homes.
Natural gas can also be converted to a liquid form called liquid natural gas (LNG). LNG is much cleaner than all other fossil fuels.
Advantages and Disadvantages
The extraction of natural gas is relatively inexpensive and is a “clean” fossil fuel from oil or coal. When natural gas burns, only carbon dioxide and water vapor are released (the gas we breathe while breathing!).
However, the extraction of natural gas can cause environmental problems. Breaking of rocks can cause mini-earthquakes. High pressure water and chemicals forced into the soil may also leak. Water sources used for drinking or bathing are dirty and may not be safe.
Other Non-Renewable Energy Sources
Fossil fuels are the world’s leading renewable energy sources, but there are others.
Nuclear energy collects strong energy in the nucleus or nucleus of an atom. Nuclear energy is released through nuclear fission, the process by which the nucleus of an atom is broken. Nuclear power plants are complex machines that can control nuclear fission to generate electricity.
Nuclear power is a popular way of generating electricity worldwide. Nuclear power plants do not pollute the air or emit greenhouse gas. They can be built in rural or urban areas.
However, it is difficult to collect nuclear energy. Nuclear power plants are very complex to build and operate. Many communities do not have a safe and reliable nuclear energy program. Nuclear energy also produces radioactive material. Radioactive waste can be highly toxic, which increases the risk of burns and cancer, blood diseases and bone decay.
Biomass energy uses the energy found in plants. Biomass energy is based on biomass raw materials, plants processed and burned to produce electricity. Biomass raw materials can include wood as well as crops such as corn or soy. if possible,
