Energy conservation

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


Energy conservation

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


Energy conservation

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


Energy conservation

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


Energy conservation

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


Energy conservation

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

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


Energy conservation

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


Energy conservation

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

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


Energy conservation

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


Energy conservation

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

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


Energy conservation

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


Energy conservation

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


A little quote big meaning

A little Quote, Big meaning

  • “We do not inherit the earth from our parents, we borrow it from our children” –

    Chief Seattle


Energy conservation

  • The earth’s inhabitants must take a serious look at energy resources, use and conservation. So thank you and please remember how important energy conservation is . 
