What is Energy? • Energy is the Ability to Do Work. • It is measured by the amount of work done, usually in joules or watts. Ntaba L. Cornwall
Energy can be found in a number of different forms, these include but are not limited: • Chemical • Electrical • Heat (Thermal) • Light (Radiant) • Mechanical • Nuclear Energy can be transformed from one form to another. Ntaba L. Cornwall
During the day, the sun gives out light and heat energy. Ntaba L. Cornwall
A car is powered by gasoline, a type of stored energy (chemical). Ntaba L. Cornwall
The food we eat contains stored energy; we use that energy to work and do all our activities. Ntaba L. Cornwall
Heat Energy is used to cook our food. Ntaba L. Cornwall
Energy lights our cities and streets. Ntaba L. Cornwall
What is Energy Conservation? • It’s another way to say “saving energy” - “conserve” means to “avoid using.” When we turn off a light, we’re conserving energy. Ntaba L. Cornwall
What is Energy Efficiency? • Energy efficiency also means using less energy, this term also means using products that don’t waste energy. Ntaba L. Cornwall
What is Energy Efficiency? cont... • For example, an energy-efficient light bulb turns almost all of the electricity it uses into light. Ntaba L. Cornwall
Why is it important to conserve energy? • Energy isn’t free. So wasting energy is the same as wasting money. Ntaba L. Cornwall
Why is it important to conserve energy?cont... • Wasting energy isn’t good for the environment. Oil can’t be replaced and it can also cause pollution. Ntaba L. Cornwall
Production of Energy • Petroleum products + Oxygen • energy • water +greenhouse gases (smoke) Ntaba L. Cornwall
Fossil Fuel • There are three major forms of fossil fuels: coal, oil and natural gas. • They were formed many hundreds of millions of years ago before the time of the dinosaurs. Ntaba L. Cornwall
Fossil Fuel cont... • We are using up the fossil fuels so it's best to not waste them. • We can save fossil fuels by conserving energy. Ntaba L. Cornwall
Coal • Coal is a hard, black coloured rock-like substance. It is made up of carbon, hydrogen, oxygen, nitrogen and varying amounts of sulphur. Ntaba L. Cornwall
Petroleum • Petroleum means "rock oil" or "oil from earth". • Natural state - Crude Oil • thick like syrup or thin like water • contains natural gas Ntaba L. Cornwall
Petroleum cont... • Colour of oil • black, golden, or dark green. Ntaba L. Cornwall
Natural Gas • Natural gas is lighter than air. Natural gas is mostly made up of a gas called methane (CH4). Ntaba L. Cornwall
Natural Gas cont... • This gas is highly flammable, it has no odour and you can't see it. It is usually found near petroleum underground. Ntaba L. Cornwall
Renewable Energy • Renewable energy is made from resources that Mother Nature will replace, like wind, water and sunshine. Ntaba L. Cornwall
Renewable Energy cont... • It is also called “clean energy” or “green power” because it doesn’t pollute the air or the water. Ntaba L. Cornwall
Energy and Recycling • Recycling helps save energy – 30% less energy • That's because they don't have to process the raw materials from scratch. Ntaba L. Cornwall
Energy and Recycling cont... • Everything you recycle at home and school helps save energy and the environment, so keep up the good work! Ntaba L. Cornwall
Energy Conservation tips • Conserving energy in your school is one of the easiest or effective ways to: • Reduce operational costs ; • Help save the environment. Ntaba L. Cornwall
Energy Conservation tips cont... • To be really effective the whole school should be involved in energy saving: • Students; • Teachers; Ntaba L. Cornwall
Energy Conservation tips cont... • Administrative staff; • Maintenance staff ; • Parents. Ntaba L. Cornwall
DO shut off the lights when you’re done using them, and turn off the TV, computer, video games and other electrical stuff when you leave the room. Ntaba L. Cornwall
DON'T leave the refrigerator door open. Every time you open the door, up to one-third of the cold air can escape. Ntaba L. Cornwall
DO replace a burnt-out light bulb with a new compact fluorescent bulb. Fluorescent bulbs use 75 percent less energy, and they last 10 times longer. Ntaba L. Cornwall
Water Conservation is Energy Conservation! Don’t waste water, it takes electricity to pump it. Ntaba L. Cornwall
DO turn off dripping faucets. One drop per second can add up to 165 gallons of water a month - that's more than one person uses in two weeks! Ntaba L. Cornwall
Another good way to conserve is to take a shorter shower. Ntaba L. Cornwall
Purchase an energy efficient microwave which has a power output of 600-700W. Ntaba L. Cornwall
Use a Power Strip! Plug home electronics into a single power strip with an ON/OFF switch. Ntaba L. Cornwall
Use the cell phone less because you have to charge it. Ntaba L. Cornwall
Turn off entertainment devices when not in use (TV, games, etc.) Ntaba L. Cornwall
Carpool or take public transportation. Ntaba L. Cornwall
Use the fan only when necessary, and disconnect it when not in use. Ntaba L. Cornwall
Nominate an Energy monitor for your class, he/she will be responsible for reminding the student to practise energy saving tips. Ntaba L. Cornwall
Buy energy efficient appliances & practise energy saving tips. Ntaba L. Cornwall
Examples of Energy Efficient appliances Ntaba L. Cornwall
Conclusions • We must conserve energy and use it efficiently to make sure we have plenty of energy resources in the future. Ntaba L. Cornwall
Conclusions cont... • All energy sources have an impact on the environment. Concerns about the greenhouse effect and global warming, air pollution, and energy security have led to increasing interest and more development in renewable energy. Ntaba L. Cornwall
Recommendation • Consider starting an “Energy Club” or “Energy Patrol” at your school. At the meetings, you can discuss ways that your school can conserve energy. You could also check on the progress of the whole school in terms of saving energy. Ntaba L. Cornwall
Recommendations cont... • Do the chart: http://library.thinkquest.org/06aug/00442/schoolelectricity.html#topschoolelec Ntaba L. Cornwall
