This week I’ve made a few cost cutting measures in my electricity costs. I finally emptied out my second refrigerator/freezer in the basement and unplugged it. I also ordered 14-10 watt led light bulbs to replace 60-65 watt bulbs.
In terms of electricity usage, an old refrigerator uses approx. 1400kwh a year, which at $0.15/kwh equates to a savings of almost $18/month or $210/year.
For the light bulbs, assuming an average use of 3 hours per day for the 14-led bulbs, savings from the change equates to approx. 770kwh a year and a savings of about $10/month or $120/year.
The savings from these two changes equates to close to $30/month. While this doesn’t seem like a huge savings if you extrapolate that over 10 years it is.
