Solar Energy Statistics
Solar power is renewable and sustainable, with homeowners increasingly switching to a solar power energy source as demand increases. Residential solar has become more affordable over the years, with money-saving incentives through the federal residential solar tax credit allowing taxpayers to claim a 26% tax credit on the cost of solar systems on their income taxes.
- Over the lifetime of a solar panel system, the average home can save between $20,000 and $75,000 in electricity costs. 9
- Solar has experienced a 33% average growth rate in the last decade alone. 10
- According to the National Renewable Energy Laboratory (NREL), your home value increases by $20 for every $1 you save on energy bills. 11
- Homes with installed solar systems, on average, sell 4.1% more compared to homes without solar. 12
High-efficiency HVAC Statistics
High-performance heating, ventilation, and air conditioning (HVAC) systems are critical to managing energy consumption, as heating and cooling account for about half of a standard home’s energy usage.
- Energy Star-certified heat and cooling equipment can yield annual savings of 10–30%. 13
- Higher-efficiency equipment can reduce energy use by 50% for electric heating and cooling systems. 14
- Properly sealing ducts can improve your heating and cooling system’s efficiency by 20% or more. 15
- The smart home thermostat market in the U.S. is projected to grow from $1.27 billion in 2022 to $3.86 billion in 2029. 16
LED Bulb Efficiency Statistics
LED lights offer many benefits, including a long life span, energy saving, and improved environmental performance.
- Lighting leads to around 15% of an average household’s electricity use, with the average home saving about $225 in energy costs per year by using LED lighting. 17
- LED lighting products can produce light up to 90% more efficiently than incandescent lighting. 18
- LED light bulbs reduce maintenance costs, lasting 35 to 50 times longer than incandescent lighting and about two to five times longer than fluorescent lighting. 19
Energy-efficiency Window Statistics
Having energy-efficient windows is an important feature in both new and existing homes. When selecting windows, it’s important to consider what you can afford and what will work best in your climate.
- Switching to Energy Star-certified windows can lower household energy bills by an average of 12%. 20
- Replacing single-pane windows can save on average 1,006-6,205 pounds of CO2 and 264-2,001 pounds of CO2 for double-pane windows. 21
- Heat gain and loss through windows are responsible for 25–30% of heating and cooling home energy use. 22
