If I replaced one of those 4 watt night lights with a 1 watt led light, how much money would I save?
Lina's response:
let's assume:
- Your electric rate from your utility company is $0.10 per 1,000 Watt-Hours or $0.10 per kWh
- The light is on for 10 hrs each night, 365 days per year
your money savings per year would be:
(4watts - 1watt) x 10 hours per day x 365 days x $0.10 per kWh / 1,000 watts = $1.095 per year
Savings = $1.10 per year
