My personal experience: How to save energy at home

Since I began a serious quest to reduce energy use at home more than four years ago, I have seen an average drop in my energy and water bills of approximately 17 percent annually. This year it should be an 8 percent savings – but that’s pretty good, too. Overall, our energy bill has decreased 43 percent, even though prices have increased.

So, how did we do it? Following is a list of some of the improvements and actions we took in our house over the past four years to reduce energy use.

• Completed a home-energy audit including blower door duct test to identify leakage.

• Started tracking electricity, gas and water use monthly on Excel.

• Sealed all ducts in the forced-air system using mastic.

• Balanced the air flow in the forced-air system, to make it more comfortable and reduce waste.

• Replaced the old refrigerator with highly efficient Energy Star unit.

• Replaced garage refrigerator with smaller Energy Star unit.

• Installed Energy Star ceiling fans.

• Set thermostat to 78 F in summer, 62 F in winter. Adjusted clothing and got used to it.

• Sealed around can lights to reduce air leakage.

• Replaced 90 percent of light bulbs with fluorescent bulbs.

• Insulated hot-water pipes with high-density foam.

• Shortened shower times.

• Turned off all landscape lighting permanently except for special occasions.

• Installed energy monitor to the main panel, to monitor energy use daily.

• Installed motion detector energy strip on all home office equipment except central processing unit (CPU), so it all turns off when I am not in the office. Manually turn off CPU.

• Plugged TV and all home entertainment equipment into strip outlet and turned off strip outlet when not in use (except for cable box).

• Installed solar-powered attic fan to reduce heat build-up.

• Cleaned solar panels yearly to increase efficiency.

• Moved roof jacks to eliminate all shading on solar panels.

• Practiced “turn lights off when you leave a room.” (Yikes, I’m becoming my mom!)

• Installed Smart AC controller (free through PG&E) to reduce energy use when the air conditioner is on.

• Kept AC off, except on the most blistering days.

We installed the following items more than nine years ago: solar panels, a tankless water heater, an on-demand water recirculation pump (Metlund ACT) and a high-efficiency forced-air unit

It’s great to see that all these actions make a difference, and that my energy bill has decreased significantly. I also feel better that I’m trying to reduce my global-warming contribution. Because I’m a green building and sustainability professional, I know there is much more I can do. And, my intention is to keep doing more, a little bit each year, one step at a time. That’s all we can each do, starting wherever we are.

I hope this list gives you some ideas. If you haven’t already done a home energy audit, I encourage you to start there, to help you create a roadmap for identifying steps you can take to reduce your energy use now and over the coming years.
