First Steps Toward Green Energy

Timers

The general idea behind a timer is that energy usage can be controlled and automatic; using energy when, where and how long it is needed thereby reducing waste. There are many types of timers and just as many ways to use them, here are some of the basic uses:

Bathroom Fan

Bathroom fan timer This should be one of the first timers that you install. You need the fan to run long enough to do its task which is usually longer then you are in the room. Energy savings comes from automating its run time to a predetermined amount of time.

Installation

Installation is straightforward but it involves electrical wiring; so if you are at all uncomfortable ask for help from a qualified individual.

  • First, shut off the power at the main breaker.
  • Test to confirm that the power has been cut.
  • Remove the switch plate cover.
  • Remove the two screws holding the switch in place.
  • The old switch should have two black wires leading to it, remove both wires and securely reconnect the two wires to your new timer as they were on the old switch.
  • Tuck everything back into the wall.
  • Secure the two mounting screws.
  • Install the cover plate.
  • Turn the power back on at the main breaker.
  • Test to confirm that the timer is operational.
Note: Some timers have added functions i.e. L.E.D. indicators and preset memory. This adds a red and green wire to the installation; follow the instructions on the packaging. If you are at all uncomfortable ask for help from a qualified individual. That is it, you now have a functioning bathroom timer that will save energy, reduce CO2 emissions, moderate humidity and limit the amount of unconditioned outside air introduced into the home.

Outside lighting

With outside lighting, you have a chance to incorporate multiple energy saving tactics, but for now we are talking about timer. Outside lighting or landscape lighting can be controlled in many ways. Installing a timer in line with the switch is one way to control how long your lights are on. Ask yourself, do I need to have lights on at 2:00 AM? Probably not. If you are concerned with security, consider a motion detector in addition to a timer.

Water heater

Your standard water heater cycles on and off 24/7. If you have an electric water heater, you can save an additional 5–12% of energy by installing a timer that turns it off at night when you don't use hot water and/or during your utility's peak demand times.

You can install a timer yourself. They can cost $60 or more, but they can pay for themselves in about 1 year. Timers are most cost effective if you don't want to install a heat trap and insulate your water heater tank and pipes. Timers aren't as cost effective or useful on gas water heaters because of their pilot lights.
