insulate, close any openings, utilize ceiling fans are a few tips.
If you are in a cold area, but insulating covers behind your socket covers.
leave the curtains closed on a hot day to keep the sun out and keep the house cool
One of the biggest problems that drive up an electric bill is the HVAC. Having a heat pump is one of the worst culprits especially if you live in an area where heat pumps aren't efficient. We always had problems with our heat pump from leaks to holes to the air handlers. UGH...always a nightmare. We switched from a heat pump to a natural gas HVAC unit and our electricity bills are much lower now and that headache is gone. It just works!
Turn lights off when not in the room, insulate the attic, use a clothes line to dry clothes, turn your thermostat up to 75-80 degrees in the summer and 63-65 degrees in the winter. Use a door draft stopper pad for the bottom of your door in the winter. A woodburning stove will help bring your heating bills down in the winter.
All of these things will help!
Here is how to lower it: https://www.youtube.com/watch?v=CCQwx8g8E5A
90% off electric bill would be hard if you have appliances plugged in (refrigerator, stove, etc) and TVs as well as heating and air
call your electric company and ask them to give you a free home evaluation on your home energy - they check for places that need caulking, leaks, etc.
Using a ceiling fan with the blades in "Summer"position will enable you to use less air conditioning. Stand fans that oscillate usually use less electric than your air conditioner, and can also be used to reduce a.c. needs, if used simultaneously.
Waterproofing your basement will reduce use of dehumidifier (you'll need to dry clothes outdoors, to avoid indoor humidity). Squeegee shower walls and wipe off tub, to reduce the time your exhaust fan/AC needs to run to remove bathroom moisture.
Place plants outdoors, whenever possible, to reduce indoor humidity in summer.
A high efficiency AC unit and Furnace will markedly reduce your electric bills.
Keep draperies closed during the hottest parts of the summer or coldest times of winter. Using insulated/thermal drapery panels should reduce heat gain/loss, providing your draperies wrap around the sides of windows.
Attic and wall/window insulation, double pane/triple pane/low e windows will reduce heat gain/loss.
A lighter colored roof absorbs less heat. Good insulation levels, roof underlayment and ice barriers will avoid ice dams/heat loss.
Clean windows reflect more heat.
Do NOT use window film on double pane windows, as they will crack in intense heat.
Wall to wall rugs with good padding will keep floors warmer in cold temps. Your electric is used each time your furnace kicks on.
Switching all light bulbs to LEDs will markedly reduce electric bills.
Turn off any lights when you're out of the room more than 15 minutes.
Waffles irons, irons use more electricity.
Use the moisture sensor on your electric dryer to save money.
Energy saver appliances will reduce your electric bills.
If you expect your bill is too high, you can ofyen get an energy audit from your power company. I kerp my eater heater turned down, do not use the high heat feature or the dry feature on my dishwasher, I wash laundry in cold water. I turn off lights. I am more chilly later so I bumped up my a/c from 73 to 75 or 76. I dry some clothes on hangers and sometimes dry clothes only part way. I take a 5 minute or less shower. I try to keep my freezer full even if it is just cartons containing ice. Also unplug appliances, do not leave your phone charger plugged in.
Unplug all lamps, computers, TVs, microwaves ....anything that you’re not using.
Most electric companies suppling residential services have different time periods during the day when the rates are higher/lower. Generally in the evenings and overnight it is cheaper than during the daytime hours, but it can also vary with the change in seasons.
If possible wait until these time periods when electricity is less expensive to run the washing machine, dryer, dishwasher, or to do tasks using hot water.
Some small appliances such as blow dryers and toasters use a surprising amount of electricity.
For example, many irons are around 1500 wt which, if it is constantly on for one hour, uses as much electricity as having 15 -100wt lightbulbs on for one hour.
Even with diligently trying all the above suggestions it is not realistic to expect them to result in a 90% reduction in your comprehensive electricity bills.
Even if you shut almost everything off (outdoor motion sensor lights, freezers, etc.) during extended periods of time when the house was vacant (such as vacation periods) at minimum you would probably have to keep the heat on low plus you would have to pay a 'monthly retainer charge' for keeping the account still active and in good standing.
These combined charges may be as low as 10%, during these selected time periods, but it is doubtful.
Insulating the house will help
Hi Ame: I'm not sure this can be done. If it could be done, everyone would be doing it. If a company is telling you they can do it, I'd look for the 'hook'. If it's too good to be true, it's probably not true.
