DIY Energy Hacks Circulate for Homeowners
Two low-cost DIY projects are being shared to help Bay Area homeowners cut energy bills. One is a sub-$2 refrigerator door alarm to stop energy waste, while a separate thermal study details how to build interior storm windows for just $1.25 per square foot to reduce heating costs.
Refrigerators account for approximately 7% of a household's total energy use, with older models consuming significantly more power. A typical modern refrigerator uses between 300-800 watts, which can cost between $68 and $136 annually to operate, depending on the model's efficiency and local electricity rates. A faulty or poorly sealed refrigerator door forces the appliance's compressor to work harder to maintain a cold temperature, leading to wasted energy. Ensuring an airtight seal can prevent this energy loss and even extend the lifespan of the refrigerator by reducing strain on its components. Single-pane windows, common in older homes, can be a major source of household energy loss, accounting for up to 25-30% of residential heating and cooling energy use according to the U.S. Department of Energy. These windows offer minimal protection against outside temperatures, leading to higher energy bills. Adding storm windows can reduce heat loss through single-pane windows by 25-50%. While professional installation can be costly, a DIY approach significantly cuts down on expenses by eliminating labor costs, which can range from $150 to $800 per window.
