Did you know?

Switching to LEDs not only saves money but also reduces heat output, lowering your cooling costs in summer. LEDs typically last 25x longer than incandescent bulbs.

How is this calculated?

Savings = (Old Watts - New Watts) × Usage × Cost
We calculate the difference in energy consumption between your current bulbs and new LEDs, multiplied by your daily usage and electricity rate. CO2 reduction is estimated at 0.85 lbs per kWh saved.

The Economics of LED

Light Emitting Diodes (LEDs) offer superior efficiency compared to legacy technologies like Incandescent or CFL. The savings come from two primary sources: reduced energy consumption (wattage) and reduced maintenance costs (longer lifespan).

1. Energy Savings Formula

We calculate the direct reduction in electricity usage based on the wattage difference and operating hours.

Annual Savings = (Old Watts - LED Watts) × Hours/Day × 365 × Rate($/kWh) / 1000

2. Environmental Impact

Reducing energy demand directly lowers carbon emissions from power generation.

CO2 Reduction ≈ Energy Saved (kWh) × 0.85 lbs/kWh

*The 0.85 lbs/kWh factor is a national average estimate for grid emissions. Actual impact varies by region and energy source mix.

3. Hidden Savings: Maintenance

While not included in this basic energy calculator, LED bulbs typically last 15,000-50,000 hours, compared to just 1,000 hours for incandescent bulbs. This results in significant savings on replacement bulb costs and labor over time.
