Here are some useful tips that I have gathered from friends. Please notify me if this indeed answers your question.

Install a Water Heater Timer

Traditional hot water heaters heat water throughout the day-whether you need it or not. Install a water heater timer, and set yours to run just when you need it. How much will this save? Expect to see a 5-12 percent reduction in your hot water heater's energy costs.

Replace Regular Night Lights with LED

LED night lights cost less than 25 cents a year to run, and are guaranteed to last a lifetime.

Switch to Solar Lights Outdoors

Harness the power of the sun by using solar lights for all of your outdoor needs. They'll absorb the sun's energy during the day, and run for free at night-a real bargain.

Don't Put Uncovered Foods/ Drinks in the Refrigerator

Condensation makes the fridge work harder, and costs you more money.

Allow Foods to Cool Before Putting Them in the Refrigerator

Placing hot foods in your fridge will increase the interior temperature, and cause your refrigerator to work harder.

Keep Your Second Refrigerator in the Basement; Not the Garage

The extreme temperatures in your garage-hot in the summer and cold in the winter-will cause your refrigerator to work harder; so if you have a choice, place your second refrigerator in the basement, where the temperature is more constant.

Cook with the Lids On

Foods cook faster with lids on because the heat can't escape.

Don't Preheat the Oven Unless You Have To

For casseroles-and other foods that require long cook times--preheating the oven usually isn't necessary. The exception: meats and other temperature-critical foods.

Use Your Microwave Instead of the Oven

Microwaves use less electricity, and don't release as much heat into your home.

Remove Sediment from Your Hot Water Heater

Sediment build up in your hot water heater can reduce the efficiency of the heating elements. Use the valve on the side of your hot water heater to drain the sediment twice yearly.
