Follow our instructional videos Green Your Home and $AVE GREEN with efficiency!
Part I - Green Your Home and $ave Green
Low or No Cost Measures To Do Today! Choose more efficient options for daily activities. Seal the energy leaks around your home and in your home's thermal envelope.
Part 2 - Slightly Bigger Investments, WAY Bigger Savings
Our professional energy audit, a comparison of insulation materials, and the insulation installation process.
Energy Efficiency at the Dream Farm
A high reflectivity roof reflects heat in the summer, and our half-buried lower level stays near 50°F all year keeping the whole house more temperate.
Sixteen inches of cellulose insulation (R-49) in the attic keeps our living space comfy. Cellulose insulation is a renewable resource, it is made with recycled newspaper and low toxicity borax for pest resistance.
3.4 inches of polyurethane foam, sprayed on exposed cinder block and in wall bond areas, provide insulation rating of R-19.
Replacing all our incandescent bulbs with LED lighting saves us up to 90% on lighting costs. LED bulbs also add less heat to our home during the summer, reducing our cooling bill.
Our high efficiency hot water heater supplements our solar thermal hot water system. We also cover it with a thermal blanket for extra savings.
Keep your fridge full to prevent warm air entry! Our high efficency fridge uses less than 1 kWh per day (our old fridge used 2.75 kWh/day) saving us over $100 annually. Your utility may actually PAY YOU to take away your old fridge.
Using an outlet strip with switch to turn off power eliminates "phantom loads" - devices that suck power all day long even when not being used.
Five Steps to Energy Efficiency
Electric Use Data Before/After Efficiency Measures
Daily Electric Energy Use at the Dream Farm by Year
Before Efficiency Measures
Year Daily Use
2002 12.32 kWh
2003 13.57 kWh
After Efficiency Measures
Year Daily Use
2004 10.15 kWh
2005 10.80 kWh
We averaged a 19% reduction in energy costs after efficiency measures.
Electric Car - 2019 Chevrolet Bolt
We drive very efficiently, and lately have been averaging 4.2 miles per kWh, with only about 10% expressway driving. Most drivers would get around 3.9 miles per kWh with the 2019 Chevy Bolt proper tire inflation.
