Switch to LED Bulbs
LED bulbs use 75% less energy than incandescent. Replacing 10 bulbs (60W→9W, 4hrs/day) saves roughly $40–60 per year at average US rates.
Unplug Phantom Loads
TVs, chargers, and game consoles draw 5–15W even when off ("vampire power"). The average US home loses $100–200/year to phantom loads. Use smart strips.
Optimize HVAC
Heating and cooling typically account for 40–50% of the electricity bill. A programmable thermostat can save 10–15% on heating and cooling costs annually.
