Energy-Saving Tips
Based on your calculations, consider these energy-saving strategies:
Heating & Cooling
Heating and cooling account for about 50% of home energy use. Setting your thermostat 2°C lower in winter and 2°C higher in summer can save up to 10% on heating and cooling costs.
Lighting
Replace incandescent bulbs with LEDs, which use 75% less energy and last 25 times longer. Turn off lights when not in use and utilize natural daylight when possible.
