If you want to make energy savings you need to know what uses up the most energy in the home and where you can make savings. Scott Murray from mega Systems who provide renewable energy infrastructures for the home and office gives the following break down on the biggest energy consumers.
In the home, air conditioning comes first followed by major appliances such as the refrigerator and electric stove. Lastly comes lighting if still using incandescent bulbs.
To cut down on your energy consumption Scott says, “The first thing to do is get an energy audit assessment from someone such as ourselves. Then make sure you get your air conditioning regularly serviced so that it is operating efficiently. Mega Systems now has energy reduction maintenance plans for air conditioning.”
Other things you can do:
Replace old appliances with Energy Star Appliances
Replace old lighting with LED Lamps
Install Solar to offset electricity costs
If you run your A/C constantly, consider installing a heat exchanger that will recover the heat from you’re a/c unit to heat your hot water
Install a Solar Hot Water system
Replace old pool pumps with new efficient models
Scott says insulation is vital and recommends having attic space inspected to see what it would cost to improve and getting windows looked at for penetrations and air leaks.
How led lighting makes a difference
For those who might consider lighting as not that much of a cost, Scott does the maths for you. “Let’s assume a typical home has 30 light sources (recessed, table lamps, outdoor lighting…etc). If we assume this customer is still using a standard $3.00 lamp that runs at 50W-60W, then 30 Lamps x 50 Watts x 2 hours a day x 365 days a year = 1095 kwh/yr and 1095 kwh x $.28/kwh = $306.00/ year.” Scott also points out that you should factor in the cost to replace this lamps when they fail and they put off heat adding to the amount of cold air needed to cool the home.
He says if you replace those lamps with LED, then the sums look much better. 30 Lamps x 6W x 2 hours a day x 365 days a year = 131.4 kwh/yr, 131.4 kwh x $.28/kwh = $36.68/yr.
LED lights have a much longer life span and they do not emit heat like fluorescent and incandescent lighting.
