1. How to save energy?

Esteban Carvajal 19/05/11

Synthesis

We as humans have a lot of ways to save energy, it is as easy as unplugging a cable. How to save energy:

- Use less oil, coal and gas. In that way fossil fuels would last longer and in that way we can produce energy. -Turn the lights off - Turn off the tv and computer ,and disconnect them - Use solar energy - Use saver bulbs - Use wind energy - Recycle - When it is bright dry your cloth outside - Don´t open the refrigerator many times - If you have a cold wear a jacket, don´t turn on the heat - Don´t take long baths - Walk or cycle to school - Don leave the fans and air conditioner on all day

Esteban Carvajal 18/05/11 [] **2.** DO lower the thermostat  during the winter. To keep warm without wasting energy, put on a sweatshirt or snuggle under a blanket.
 * **Top 10 Rules for Saving Energy ** ||
 * **1**. 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.

**3.** DON'T leave the refrigerator door open. Every time you open the door, up to one-third of the cold air can escape.

**4.** 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.

**5**. DO remind grown-ups to use cold water in the washing machine . Hot water won’t get the clothes any cleaner, and it wastes a lot of energy. ||

|| **6**. DO turn off dripping faucets.  One drop per second can add up to 165 gallons of hot water a month - that's more  than one person uses in two weeks!

**7.** DON’T take a long bath <span style="font-family: Verdana,Arial,Helvetica,sans-serif;"> – take a short shower instead. It might take 25 gallons of hot water to fill the bathtub, <span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: medium; line-height: normal;"> compared to only seven gallons for a quick shower

<span style="color: #9933ff; font-family: Verdana,Arial,Helvetica,sans-serif;">**8.** DO close the curtains <span style="font-family: Verdana,Arial,Helvetica,sans-serif;"> during hot summer days to block the sun. During the winter, keep the curtains open

<span style="color: #cc33ff; font-family: Verdana,Arial,Helvetica,sans-serif;">** 9. ** Help a grown-up put plastic sheeting on windows <span style="color: #9933ff; font-family: Verdana,Arial,Helvetica,sans-serif;">. <span style="font-family: Verdana,Arial,Helvetica,sans-serif;"> Blocking cold drafts is called “weatherizing” and it can save a lot of energy.


 * <span style="color: #9933ff; font-family: Verdana,Arial,Helvetica,sans-serif;">**10.** DO help your mom or dad plant a tree <span style="color: #000000; font-family: Verdana,Arial,Helvetica,sans-serif;"> to help shade your house on hot summer days  ||

 * Difficulty:**Moderately Easy

Instructions
Check for any leaks or places where you might lose energy from your home. Completely close all windows, doors and vents that lead to the outside and turn off any gas appliances. Set up fans to pull air out of rooms away from doors and windows by placing the fans near the door blowing air out of the room. Check for air leaks near any window, doors, corners, electrical outlets and switch plates by wetting your hand and moving it near these locations. This will help you feel whether a draft occurs or not. Use fans in the summer and space heaters in the winter. These consume less energy than the air conditioner or furnace and let you set the thermostat to higher or lower temperatures correspondingly. Adjust settings on your appliances so they use less heat and energy. Turn off the heated dry cycle on your dishwasher. Raise the temperature in your refrigerator and freezer to the highest point that will keep your food cool, around 35 to 40 degrees for the refrigerator and 0 to 5 degrees for the freezer. Use the cold water setting on the washing machine as much as possible to reduce the energy needed to heat the water. Also, turn down the temperature on your water heater to 120 degrees. Many water heaters are set too high and you usually won't notice the difference. Purchase the most energy-efficient models of appliances available when you need to upgrade home appliances. Service all appliances regularly to keep clogged filters and broken or leaky gaskets from wasting energy. Replace incandescent light bulbs with compact fluorescent versions, especially for lights that remain on for extended periods of time, such as security or outdoor lights. Use timers on outdoor lights so you won't forget to turn them off during the day. Weatherize your house. Caulk all cracks and crevices that allow air in from the outside. Apply energy-efficient treatments to windows. Install energy-efficient insulation with an R-value of 40 for ceilings, 11 for basement walls and 19 for floors

**Waste of energy is a major problem on the world. To avoid this there are various things WE can do.**


 * **We can use less oil, coal and gas. In that way fossil fuels would last longer and in that way we can produce energy.**
 * **To make energy in an efficient way we can use solar panels and wind turbines.**


 * **We must:**
 * 1) **Turn off our tv (do not leave it stand by) and disconnect it.**
 * 2) **If it´s save walk or cycle to school.**
 * 3) **Turn off the lights when its bright. And don't let the lights on when there is no one in the room.**
 * 4) **Have a shower instead of a bath, it uses less hoot water.**
 * 5) **If you are cold, put on a jumper instead of turning up the heat.**
 * 6) **Recycling save energy, so save up bottles, paper, cans and put them in the bin.**
 * 7) **When it is dry outside, use the sun to dry your clothes.**

16/05/2011 Isabella Vallejo If we use less energy, oil, coal, and gass it will last longer. <span style="color: #ff0067; font-size: 14px; font-weight: normal; line-height: 20px; margin: 0px; padding: 0px;">Possible solutions: We could use water, sun, and wind energy that do not produce Carbon dioxide when they are turned into electricity, and it is a renewable energy. We could use solar panels as solar energy. We could use wind turbine as wind energy. We could use Tides ( Variations in the water surface), Dams(picture 1), Water falls, and Tidal barrages( when sea meets with a river). (BOOK: save energy)

** 1. Don’t leave tv or video on standby, turn it off at the power button. **

** 2. Fit a lagging jacket on the hot water cylinder in your hot press. It keeps the hot water hot for longer, just like when we put on our winter jackets to keep us warm. **

** 3. Recycling saves energy, so save up your bottles, cans and paper and put them in the recycling bin. **

** 4. When it’s dry outside, use the sun and wind to dry your clothes instead of a tumble dryer. **

** 5. When it’s bright, turn off the light and don’t leave the light on if there’s no one in the room. **

** 6. Have a shower instead of a bath, it uses a lot less hot water. **

** 7. If you’re cold, put on a jumper instead of turning up the heat. **

** 8. If it’s safe to do so, walk or cycle to school. **
