We all want resilient energy and water resources, and the first step is to reduce our consumption which is key to reducing monthly expenses.
Let’s get back to basics for a minute. Energy costs are skyrocketing. The cornerstone of sustainability is conservation within one’s own daily environment. While we endeavor for cleaner energy production methods like geothermal, use the following tips to make your home as energy efficient as possible while keeping it comfortable – and save a bundle in the process!
Seal the envelope. You can save a lot of money just by sealing the cracks in your home with caulking and weather stripping. A blower door test measures the airtightness of your home and can identify leaks. Leaks can occur through doors, light fixtures, outlets, or windows with decorative molding.
The Department of Energy advises that a well-insulated attic is one of the best ways to save money, increase comfort, and improve energy efficiency. How much and what kind depends on where you live.

In warmer regions, a radiant barrier in your attic can make a big difference in your cooling bills.
Your furnace and air conditioner should be energy-efficient models connected to a programmable thermostat. Consider raising the thermostat to 78 degrees on summer days when everyone is out, or to 65 degrees in winter. Change filters according to the manufacturer’s recommendations to lower utility costs.
Use compact fluorescent lighting (CFLs) to save money. There are many styles to choose from these days.
Replace appliances with energy-efficient models as the old ones die. EnergyStar.gov is a good resource to review before shopping. Research rebates through local utilities and tax incentives.
Install solar PV panels on your roof or adjacent buildings. Roll your meter backward by generating your own power and get credits from your electric company for selling them power. Tax incentives are currently at 30% and local utility rebates are similar depending on time and location. Go to dsireusa.org for updates.
Consider a geothermal heat pump to provide most of your heating and cooling needs. This investment is significant, but is made more manageable with the current 30% ITC credit. These systems will work quietly for many years to come and are a good alternative when it’s time to replace your air conditioning unit. If your AC unit is 7-10 years old, consider a heat pump.
Use the sun’s rays to generate hot water. Solar hot water heaters can be another cost-effective way to heat water for home use. With a projected cost savings of 50%, these can pay for themselves in just a few years. If you are nursing your old water heater through its final years, insulating the hot water pipes can improve energy efficiency. Removing sediment at the base of the tank may also improve efficiency.
Remember the obvious. Plant deciduous trees on the south side of your house that will shade you in summer and shed their leaves for winter to allow sunlight through. Also, consider sunshades on southern exposures – window awnings and patio solar screens – to combat extreme summer temperatures and make your indoor/outdoor environment more comfortable.
Replace your old windows. Find double-pane models and consider the part of the country you live in. In the North, choose gas-filled, low-emissivity (low-e) windows that reduce heat loss. In the South, seek spectrally selective coatings that reduce heat gain.
In winter, run ceiling fans to circulate heated air trapped high up near the ceilings. This will make the room more comfortable and lower your heating bill.
For lower overall utility costs, run appliances only during off-peak times.
