What is energy conservation?

It is when we reduce a certain amount of use of energy and save our money by cutting our electricity bill as well as energy for future use.Energy conservation can be useful for our future generation and will help them and us in a lot of ways, as you know some parts of the world don’t have or very less energy.

It was used back then…It was used back then…• When eletricity and When eletricity and

gas did not exsist,it gas did not exsist,it was a hard time for was a hard time for them to work. They them to work. They used natural used natural resources and their resources and their homes were not homes were not quite developed quite developed which means they which means they cut no or less trees.cut no or less trees.

After a few decades, After a few decades, people learned how people learned how to use water power to use water power to turn paddle wheels to turn paddle wheels and wind power for and wind power for transportation and transportation and irrigation.irrigation.

•People also People also learned to use learned to use the chemical the chemical energy stored in energy stored in materials like materials like wood to cook and wood to cook and heat their homes.heat their homes.

•But machines and But machines and technologies technologies introduced during the introduced during the Industrial Revolution of Industrial Revolution of the late 18the late 18thth century century required the use of required the use of other energy resources, other energy resources, especially fossil fuels.especially fossil fuels.

• Fossil fuels like coal, oil and Fossil fuels like coal, oil and natural gas are considered to natural gas are considered to be nonrenewable energy be nonrenewable energy resourcesresources. .

•Our fossil fuel reserves Our fossil fuel reserves formed over millions of formed over millions of years from decaying years from decaying plants and animals.plants and animals.

•As we use them up, they As we use them up, they will not be replenished will not be replenished in our lifetimes.in our lifetimes.

• With the modern world With the modern world depending upon coal, oil and gas depending upon coal, oil and gas for a majority of its energy needs for a majority of its energy needs and the prediction that the world and the prediction that the world will nearly double its need for will nearly double its need for energy resources in several energy resources in several decades, it is important to decades, it is important to conserve energy and to conserve energy and to investigate alternate energy investigate alternate energy resourcesresources

• There are many renewable There are many renewable energy sources that are energy sources that are alternatives to fossil fuels, alternatives to fossil fuels, but some are not without but some are not without controversy.controversy.

• For instance, nuclear power For instance, nuclear power is used to generate about 25 is used to generate about 25 percent of the world’s percent of the world’s electricity, but it has inherent electricity, but it has inherent risks, especially in the risks, especially in the disposal of radioactive wastedisposal of radioactive waste..

•Hydroelectric plants use running Hydroelectric plants use running water to generate electricity, water to generate electricity, however they may flood nearby however they may flood nearby lands and can disrupt the normal lands and can disrupt the normal flow of water, both of which flow of water, both of which negatively affect the negatively affect the environment.environment.

• Wind power is increasingly being Wind power is increasingly being used as a clean source of used as a clean source of renewable energy.renewable energy.

• Turbines harvest wind on wind Turbines harvest wind on wind farms and generate electricity. farms and generate electricity. The electricity can be supplied The electricity can be supplied in cities, towns ect.in cities, towns ect.

•Solar power is a promising, renewable Solar power is a promising, renewable energy resource than can be turned energy resource than can be turned into electricity, and it is used in many into electricity, and it is used in many toys and even home heatingtoys and even home heating..

• Many other alternative energy Many other alternative energy sources like geothermal power, sources like geothermal power, which draws upon the earth’s which draws upon the earth’s natural heat, and biomass, which natural heat, and biomass, which produces an alternative to produces an alternative to gasoline, are being considered in gasoline, are being considered in the movement away from fossil the movement away from fossil fuel dependence.fuel dependence.
