Save energy

  1. 1. Presented By
  3. 3. WHY TO SAVE ENERGYWHY TO SAVE ENERGY Energy efficiency and conservation are necessary, because energy consumption is a major cause of environmental degradation. All types of energy use result in environmental costs, it’s just a matter of degree. And most modern American activities seem to involve energy consumption. Our transportation, food production, manufacturing, governments, recreation and household management all consume energy. At the same time, our major energy supplies (oil, coal, and gas) are finite. They are not renewable, yet we burn through these fuels as if there were no tomorrow. The energy supplies which are renewable (solar, wind, thermal) are not being used as widely or thoughtfully as they should be.
  4. 4. Environmental Costs of Energy Consumption Air Pollution --- Most forms of energy generation produce large amounts of air pollution as a byproduct (except solar and wind). The burning of fossil fuels and biomass will result in carbon dioxide, sulfur dioxide, nitrous oxides, sulfuric acid, hydrochloric acid, carbon monoxide, polyaromatic hydrocarbons (PAH’s, such as benzo- a-pyrene), ozone and radioactive emissions. These emissions are a direct threat to public health.
  5. 5. Wildlife Impacts --- All of the factors above contribute to the loss of wildlife habitat and to poisoning of wildlife. Many species are being decimated to the point of extinction, with climate change likely to push many over the edge. They don’t have time to adapt.
  6. 6. Toxic Contamination --- In addition to the toxic pollutants listed under air pollution, many toxic trace contaminants are released from fuel burning, including serious contaminants such as mercury, arsenic, lead, and chlorinated organics such as dioxin.
  7. 7. Water Pollution --- Fuel burning also results in fallout from the air of toxic contaminants that gradually build up in the sediments of wildlife of our rivers, lakes and streams. Acid rain is still an active concern in many areas, poisoning our waterways, damaging property and reducing the productivity of our forests and croplands.
  8. 8. Radioactive Waste --- Despite claims by its proponents, nuclear energy is far from “clean,” in that uranium mining has despoiled many large tracts of land with direct radioactive contamination and wind erosion of radioactive dusts. After decades of investigation, the nuclear industry has also failed to find a safe means of disposing of radioactive wastes which are accumulating too rapidly and will remain dangerous for thousands of years. The potential for nuclear accidents or sabotage is also a concern.
  9. 9. Let's Save Energy! Using energy wisely means being efficient. We use energy everyday at home, at school, at work, and even when you're playing. By saving energy you're helping to save the world's energy resources like gas, oil and water and you're also saving money on your utility bills. Best of all, by using energy wisely we can cut down on pollutants in the air and water, making a better environment for everyone. Think about what would happen if there wasn't enough energy . . . there would be no light to turn on when it got dark . . . there would not be any hot water for the shower or heat for your house in the winter . . . no gas or oil to drive the car . . . so there are lots of reasons we should save energy.
  10. 10. Fight the Light! Don't leave lights on when no one is in the room. If you are going to be out of the room for more than five minutes, turn off the light. If you know of a light that everyone forgets to turn off, make a sticker or a sign to hang next to the switch that says "Lights Out!" or "Don't Forget!" Where possible, use compact fluorescent light bulbs. Those funny-looking bulbs produce the same amount of light by using 1/4 of the electricity. Plus, they last for years and years without burning out. There's one light bulb that firefighters in Livermore, California, never turn off. It uses very little energy and has been burning for 101 years!
  11. 11. Turn off the TV when no one is watching it. The same goes for computers, radios and stereos - if no one using it, turn it off. Turn off all the appliances at the surge protector/control strip - that four- or six-plug extension chord that you plug all your computer things into. Some devices, like modems or other networking boxes are drawing small amounts of power all the time. Check with your folks first, but the best thing to do is turn them ALL off at the surge protector. Don't Leave Things Turned On
  12. 12. It's a Matter of Degrees!It's a Matter of Degrees! In warm weather, the thermostat at home should be set at 78 degrees. (Don't do this, of course, if it will cause health problems for anyone in your family.) When no one is home, set the thermostat at 85 degrees. That way, you'll reduce the need for air conditioning and you will save energy. If you have ceiling fans or other fans, turn them on. The blowing air can make you feel 5 degrees cooler, without running the family's air conditioner. Fans use a lot less electricity than air conditioners! In cold weather, wear warm clothing and have your thermostat set to 68 degrees or lower during the day and evening, health permitting. When you go to sleep at night, set the thermostat back to either 55 degrees, or turn it off. When you leave home for an extended time, set the thermostat at 55 degrees or turn it off, too. That way, your family can save from 5 percent to 20 percent on your heating costs. (Don't do this, of course, if it will cause health problems for anyone in your family.)

There are a lot more ways to save energy and it's important that everyone pitches in. Check out our checklist on things your family can do to save energy. Together we can all save energy! Don't leave the refrigerator door open. Decide what you want BEFORE you open the door.
  14. 14. In the Bathroom Wasting water wastes electricity. Why? Because the biggest use of electricity in most cities is supplying water and cleaning it up after it's been used! About 75 percent of the water we use in our homes is used in the bathroom. Unless you have a low flush toilet, for example, you use about five gallons to seven gallons of water with every flush! A leaky toilet can waste more than 10,000 gallons of water a year. Wow! Drippy faucets are bad, too. A faucet that leaks enough water to fill a soda bottle every 30 minutes will waste 2,192 gallons of water a year. Another simple way to save water AND energy is to take shorter showers. You'll use less hot water - and water heaters account for nearly 1/4 of your home's energy use.
  15. 15. In the Kitchen According to researchers who are paid to study such things, a load of dishes cleaned in a dishwasher uses 37 percent less water than washing dishes by hand! However, if you fill up one side of the sink with soapy water and the other side with rinse water - and if you don't let the faucet run - you'll use half as much water as a dishwasher does. Doing the dishes this way can save enough water for a five- minute shower! If you need to warm up or defrost small amounts of food, use a microwave instead of the stove to save energy. Microwave ovens use around 50 percent less energy than conventional ovens do. For large meals, however, the stove is usually more efficient. In the summer, using a microwave causes less heat in the kitchen, which saves money on air conditioning. Don't keep the refrigerator door open any longer than you need to. Close it to keep the cold air inside! Also, make sure the door closes securely. There is a rubber-like seal around the door that you can test. Just close the door on a dollar bill, and then see how easy it is to pull out. If the dollar slides out easily, the door is probably leaking cold air from inside. Is there an old refrigerator sitting in the garage or someplace else at home? Old refrigerators are real energy hogs! An old refrigerator could be costing your family as much as 4800 a year to operate. Urge your parents to replace it if they don't need it, and remind them that one large refrigerator is cheaper to run than two smaller ones.
  16. 16. Shocking News About Batteries Did you know that Americans use an average of about eight batteries a year per person? Batteries that are thrown away produce most of the heavy metals - dangerous substances like lead, arsenic, zinc, cadmium, copper, and mercury - that are found in household trash. These metals are toxic. They can be harmful to humans and wildlife. When discarded batteries from our trash wind up in landfills, these dangerous metals can seep into the ground water and eventually into the food chain. So, instead of throwing batteries in the trash, we should all take them to a toxic waste disposal area, if at all possible. Turn off the toys and games (like GameBoys TM) that use batteries when you are not playing with them. That makes the batteries last longer, and you won't need as many of them. Forty percent of all battery sales are made during the holiday season. Ask for holiday gifts that do not require batteries. Ask your parents to buy rechargeable batteries and a recharger.
  17. 17. Think About What Your Family Buys If you buy things that can be used over and over instead of buying disposable items that are used once and then thrown away, you will save precious natural resources. You'll also save energy used to make them, and you'll reduce the amount of landfill space we need when they are thrown away. Those same savings happen you buy things that will last instead of breaking right away. Well-made items may cost a little more to begin with, but they are usually worth the money because they last for a long time, and you don't have to replace them. When your family goes shopping, think about taking bags with you. Only about 700 paper bags can be made from one 15-year-old tree. A large grocery store can use that many bags before lunch! Plastic bags start out as either oil or natural gas. Oil and natural gas are non-renewable resources. This means they can't be reused, and when they are all gone, they are gone forever. And throw-away bags add a lot of pollution to the environment. If plastic and paper bags are used once and go to landfills, they stay there for hundreds of years Some stores offer discounts for people who use their own bags. For every bag reused, they give money back - usually about five cents for each bag. With your parents, pick a spot in your house to store bags that you get from the grocery store. These bags can be used to carry things to friends' houses or for trash linings. After bags wear out, recycle them.
  18. 18. Try ORGANIC fresh fruits and vegetables. Generally things with the fewest ingredients on the label are the safest bet. If you can't ride a bike or don't own one, try to walk to places as much as possible, but if you need transportation, see if you can use mass transit (like a train, bus, or subway). Since more people use them (so less people are using cars), less fossil fuels are being released. Generally, don't waste anything (this does not mean eating every left-over you find; you can pack it in containers and put it in the refrigerator or freezer). If you know of some poor people, they could appreciate this a lot and look up to you for it. Help your neighbors! And, if you are sure you don't want it anymore or that your fridge/freezer is full, try putting it outside of your house, or somewhere close to starving animals. They would be more than happy to gobble it up. For example, bread from your breakfast that you just can't eat anymore - break it down and leave it outside for the birds. Although recycling is great, it's even better to conserve. That means reusing paper as much as possible, or refilling your water bottle instead of buying a new one, and so on. If you are just getting a soda, or something else that does not require a bag (or if you're just not going to use it), don't take one. Otherwise, use scrap fabric to sew a 'Bag Bunny' to hold plastic bags to be reused. When grocery shopping, bring your own bag(s) (cloth ones are the best kind). Some places even give slight discounts for you bringing in your own bag. Some shops also make you pay for those plastic bags, so you'll be saving money as well as do good deeds! The next time you order a beverage, bring your own mug (or buy one of theirs). Not only will you save 15 cents, but you will also help by not wasting cups.
  19. 19. Ask your local Waste Management Service if you could help out. Maybe you could make fliers and put them around town, to make people aware of the earth. Start a day where you and the town will pick up garbage If possible, drink your tap water! You'll have more cash in your pocket and reduce the chances of a factory creating more unnecessary bottles, meaning less energy as well as resources used up. If you don't have time and space for clothes that you no longer need, donate them to charity! Every time you do, you make a lonely soul a grateful spirit, as well as motivate others to do good! Although recycling Before you recycle something, like an aluminum can, it's best to wash it out first. Did you know that one aluminum can can be recycled 10 times? Before recycling aluminum cans, take off the tabs and save them. There are many hospitals that will accept them and use them to make medical equipment. Spread the word! Start a club at school, a fund raiser, or anything else that would help make people aware of the environment. When it comes to saving the planet's water, don't be boring! You're more likely to use something if you like it, so buy a colorful water bottle or decorate your glass bottle with pretty glass paint!
