Energy


Energy efficiency means:


  • Using advanced technologies to provide better quality energy services with less energy.
  • Getting the most productivity from every unit of energy.
  • Getting the desired energy services - comfortable homes, profitable businesses, convenient transportation - with less energy use, less air pollution, and lower total cost.
  • Using energy wisely.
  • Eliminating energy waste.
  • Using technology to easily reduce energy use without having to daily "remember" to do it yourself.

Energy efficiency saves consumers money, increases comfort, protects the environment, enhances the economy, and promotes national security.  When energy efficiency is combined with smart energy practices - like turning off lights, TVs, computers and electronics, that you're not using - all of the benefits above are compounded.

Computers & Monitors


Enable the Power Management Settings on Your Computer and Monitor - All Seattle University computers (not monitors) must be left ON at all times including nights and weekends. Generally OIT tries to complete software and operating system updates late at night so as not to disrupt workday activities. These changes update anti-virus software, some applications, operating systems and security configurations.

Power management places your computer and monitor into a low-power mode during periods of inactivity. The computer "awakens" upon touching the keyboard or mouse.

Electronics


Kill the Energy Vampire!-
 Even when electronic devices are turned off, they use energy. Electronic devices that are ready to operate or receive signals at all times act like vampires silently sucking away energy even when they are turned off.  Types of electronics include: coffee makers, TVs, DVD players and stereos. The chargers for iPods, cell phones and cameras consume a small amount of energy anytime they're plugged in, even if they're not charging.  This wasted energy is known as standby or phantom energy loss.  Kill your energy vampires and reduce your carbon dioxide output by up to 1,000 lbs and your electric bill by up to $256 per year.

 

Kill the Vampire with a Power Strip - To save the time and hassle of unplugging all the components of a computer or home entertainment system, plug them into a power strip or surge suppressor that turns off all electronics with a single switch (surge suppressors still protect against power spikes when plugged in, even if switched off).
Unplug It - Unplugging devices when they are not being used eliminates energy loss.

Choose Energy Star Qualified Products - Energy Star products are guaranteed to use the least amount of energy in their product category.  The www.energystar.gov web site has a list of products in 50 categories including office equipment, appliances, electronics and lighting. In 2005, energy efficient appliances reduced Americans' energy bills by about $12 billion.  Energy Star is a joint program of the Environmental Protection Agency and the Department of Energy. 

Lighting


Change Your Light Bulbs Once - If every household in the U.S. replaced 3 old-fashioned incandescent light bulbs with CFL bulbs, we would prevent a trillion pounds of greenhouse gases from entering the atmosphere.  CFLs cost more to buy, but your total cost will be less when you include your monthly electric costs.  By switching from incandescent to CFLs, you will reduce your electric bill by up to $30 annually for each bulb.  Compare the total cost (purchase price + money electric costs) of using CFLs and incandescent bulbs.  You'll need to know what Seattle City Light charges for electricity.

Compact Fluorescent Lights (CFLs) - 1 bulb will last 6,000 to 10,000 hours. One bulb lasts as long as 10 incandescent bulbs and uses about 66% less energy. Tips for buying

Light Emitting Diodes (LEDs) - 1 bulb will last 100,000 hours 

Incandescent bulbs- 1 bulb will last between 750 and 1,000 hours. Only 10% of the power consumed produces visible light, making it a ridiculous light source. 90% of the power consumed by an incandescent bulb is emitted as heat; this is why they are used to hatch eggs.  

Turn off Lights - Leaving a fluorescent light turned on uses more electricity than turning the light on and off. The opposite statement is an urban myth

Laundry

Air Dry Your Clothes - Hang your laundry to dry instead of using the dryer.  Reduce carbon dioxide output by 700 lbs. and your energy bill by $75 annually. 

Skip the Pre-wash Cycle -  Reduce the amount of energy and water used to wash your laundry by passing on the pre-wash cycle.

Wash Laundry in Cold or Warm Water - About 90% of the energy used for washing clothes is for heating the water. Unless you're dealing with oily stains, warm or cold water will generally do a good job of cleaning your clothes. Proctor & Gamble claims U.S. consumers can save up to $63 per year in energy costs by washing in cold water.

Heating Your Space

Put on a Sweater - Instead of turning up the heat in your home or office, wear more clothes. Reduce your carbon dioxide by 1,000 lbs. and your energy bill by up to $250 per year.

Adjust Your Thermostat - Move your heater thermostat down two degrees in winter and up two degrees in the summer. This will reduce your carbon dioxide output by up to 2,000 lbs and your electric bill by $98 per year.

Cooling Your Space


Change the AC Filter - Clean or replace dirty air conditioner filters as recommended. This will reduce your carbon dioxide output by up to 350 lbs. and your energy bill by up to $150 per year.

Get Over Your AC - Keeping your room or office cool isn't all about the AC. Covering up your windows with a curtain can cut down on 40% of the heat your space absorbs from the sun. Use a fan instead of AC; fans use one tenth the energy of air conditioners. 

Heating Water

Take Shorter Showers - Showers account for 65% of all water heating costs. Taking a shorter shower will reduce your carbon dioxide output by up to 350 lbs. and your energy bill by up to $99 per year. Buy a shower timer.  Shower Life Story

Check Your Water Heater - Keep your water heater thermostat no higher than 120 degrees F. This will reduce your carbon dioxide output by up to 550 lbs. and your energy bill by up to $30 per year.

Insulate Your Water Heater - Keeping your water heater insulated will reduce your annual carbon dioxide output by up to 1,000 lbs. and your energy bill by $40.

Switch to a Tankless Water Heater - Your water will be heated as you use it rather than keeping a tank full of hot water day and night. Reduce your carbon dioxide by 300 lbs. and your energy bill by $390 per year. 

Put a Lid on It - Using cooking pots with lids reduces time and energy used by 20%.

Let the Sun Heat Your Water - Solar water-heating systems can be used in any climate to heat your water supply. Since they use no fossil fuel energy, they save a lot of CO2 emissions. A typical household can meet 50 to 80% of its hot water needs using solar heat. Though they cost slightly more to install than a traditional system, your fuel source - the sun is free. (Learn the basics on solar water-heating systems here. For more details, click here.)

Seal Your Home's Shell

Insulate Your Home - Insulate your walls and ceilings and reduce home energy consumption by as much as 25%, carbon dioxide output by 2,000 lbs. and energy bill by $245 per year.   

Weatherize Your Home - Caulk and weather strip your doorways and windows. Reduce carbon dioxide output by 1,700 lbs. and your energy bill by $274 per year.

Switch to Double Pane Windows - Double pane windows keep more heat inside your home so you use less energy. Reduce your carbon dioxide by 10,000 lbs. and your energy bill by $436 annually.

Other Actions

Take the Stairs not the Elevator - An elevator uses energy and that energy releases carbon dioxide into the atmosphere.  Instead, create your own energy and non-polluting carbon dioxide from breathing. Walking up and downstairs is a free workout, increases leg power and reduces the risk of injury.  Exercise relieves stress and increases bone density, which reduces osteoporosis.  Studies show participants who climbed more than 55 flights per week significantly lowered their risk of mortality.

Open the Fridge Less - Think of everything you want before you open the fridge door. Cold air and money are wasted every time you open the fridge.

Clean Your Fridge's Coils - Clean the coils at the back twice a year with a vacuum and rag.  This will reduce the work done by the compressor, making your fridge run more efficiently and resulting in less electricity used.
