Energy Myths & Facts
1. Switching lights on and off uses more energy than leaving them on if I’m only going to be out of the room for a short while.
FALSE: This used to be true, but now the rule is that the longer the light is on, the more energy it uses. The energy used to switch a light on and off is less than that of leaving it on, so switching lights off when you leave the room saves energy, whatever type of bulb you have.
2. Leaving the heating on overnight uses less energy than re-heating a cold building.
FALSE: A boiler that spends an hour heating up a room in the morning is working no harder than a boiler that spends 14 hours switched on overnight. The only difference is that one is switched on for an hour, and the other for 14! Source: University of East London, 2015
3. Repeatedly turning computers and lights on and off reduces their lifespan.
FALSE: Leaving computers on when not in use actually reduces their lifespan, because moving parts wear out faster. Lights are designed to be switched on and off many times a day without affecting their lifespan.
4. Energy saving light bulbs can’t be used with dimmer switches.
FALSE: There’s now many energy saving light bulb options, including ones that can be dimmed, and ones with different hues of light.
5. Computer monitors use less energy when the screen saver is on.
FALSE: LCD screens use exactly the same amount of energy, whatever color they are displaying, so the screensaver uses just as much energy as when you are working. The best thing to do if you are leaving your desk – switch off your computer screen.
Don’t dally in front of an open refrigerator!
♺ Keeping the fridge door open while you decide what you want to eat may not seem like a big deal, but that open door accounts for 7% of the appliance’s total energy use (Home Energy Magazine, 2014).
♺ When you open your refrigerator, the cold air that keeps your food fresh escapes and is replaced by warm air from the room. Your refrigerator’s compressor has to then drive the warm air out and bring the temperature back to normal, elevating not only your monthly energy bill, but also your environmental footprint.
♺ Being careless with opening and closing your fridge door wastes 50 to 120kWh a year. Putting this into perspective, 50kWh of energy could run your dishwasher 20 times and 100kWh could run your washing machine 50 times (University of Florida, Institute of Food and Agricultural Sciences, 2014).
Un-Plug or Hit the Switch on Power Strips
a. Anything plugged in is using energy – copier, printer, coffee pot, microwave,
water cooler, appliances, etc.
b. Un-plug equipment at the end of the day OR
c. Plug everything into a power strip and turn the power strip off.
d. Some schools have electronic displays that are left on even when the school is closed. At the end of the day, these displays can be shut off manually or with simple timers.
SPRING IS HERE!…
The first thing you may want to do when the temperatures are warmer is open up the doors, but DON’T. What you may not realize is the air inside your buildings are still being conditioned (heated or cooled) even in these winter/spring months. What that means is ENERGY is still being used and $$ are still being spent. Opening the door causes the heating/cooling unit to work harder to keep the temperature in the building to the set points on the thermostat…thus, wasting both ENERGY and MONEY.
Lighting – the Right Light for the Right Task
Many offices, workrooms, or classrooms can easily reduce lighting without affecting productivity. Turn off as many unnecessary lights as possible. Light only those areas that are needed at the time. Providing the right lighting can save up to 15 percent on your lighting bill (California Energy Commission, 2015).
Replace your lamp’s incandescent light bulbs with LEDs or compact fluorescent lights. A compact fluorescent light uses 75 percent less electricity to produce the same amount of light as an incandescent bulb (US Department of Energy, 2015). The compact fluorescent will last about 10,000 hours as opposed to the 600 to 1,000 hour average life of an incandescent (California Energy Commission, 2015). By replacing a 100-watt incandescent with an equivalent 25-watt compact fluorescent, you can save more than $90 per bulb in electricity costs over the 10,000-hour lifetime of the compact fluorescent (California Energy Commission, 2015).
“Know Your Energy Use…”
- Minimize energy costs by reducing USE and managing LOAD
- USE (kWh) is the number of hours you have lights on, items plugged in (both on & off), and how hard and long the air conditioning units run.
- LOAD (KW) is how much energy your building uses in a given 15 minutes.
To Reduce USE (kWh)
- Turn off unnecessary lights; Check thermostat set points; Keep doors closed to reduce loss of conditioned air/air conditioning run times and Unplug items when not in use (or put on power strips for ease of shutdown)
To Reduce LOAD (KW)
- Stagger the time you power up all the equipment at the store (computers, lights, etc.) to spread out the ‘load’.
- Stop leaky faucets – A dripping faucet may seem harmless, but you’d be surprised at how much water is lost. According to the U.S. Geological Survey’s Water Science School, one faucet that drips 4 drips per minute wastes 138 gallons of water a year.
- Replace old toilets – Toilets manufactured before 1994 use up to five gallons per flush compared to 1.6 gallons for newer toilets. According to Savingwater.org, replacing an old toilet can save up to 10,500 gallons of water each year, depending on utility rates and usage habits.
- Maintain appliances – Appliances can sprout leaks because of aging materials, improper connections or ruptured hoses. Sometimes leaks can go unnoticed for weeks, wasting water and potentially causing damage to your home. Be sure to check your water heater, washing machine, refrigerator, and other appliances regularly.
Water conservation in the home and school…
1. Check faucets and pipes for leaks.
A small drip from a worn faucet washer can waste 20 gallons of water per day. Larger leaks can waste hundreds of gallons (Town of Bristol, 2015).
2. Don’t use the toilet as an ashtray or wastebasket.
Every time you flush a cigarette butt, facial tissue, or other small bit of trash, five to seven gallons of water is wasted (Montclair Township Office of Environmental Affairs, 2015).
3. Check your toilets for leaks.
Put a little food coloring in your toilet tank. If, without flushing, the color begins to appear in the bowl within 30 minutes, you have a leak that should be repaired immediately (Eartheasy, 2015).
4. Install water-saving shower heads and low-flow faucet aerators.
Hot showers can use five to ten gallons every unneeded minute. “Low-flow” means it uses less than 2.5 gallons per minute (Natural Resource Defense Council, 2015).
5. All faucets should be fit with aerators.
This single best home-water conservation method is also the cheapest!
6. Take shorter showers.
One way to cut down on water use is to turn off the shower after soaping up, then turn it back on to rinse. A four-minute shower uses approximately 20 to 40 gallons of water (Eartheasy, 2015).
7. Turn off the water after you wet your toothbrush.
Just wet your brush and fill a glass for mouth rinsing.
8. Use your dishwasher and clothes washer for only full loads.
Automatic dishwashers and clothes washers should be fully loaded for optimum water conservation.
9. Keep a bottle of drinking water in the fridge.
Running tap water to cool it off for drinking water is wasteful.
