How much electricity does one single red LED use in a year?
Red LEDs typically have a forward voltage of about 1.7 volts (V) and draw about 20 milliamperes (mA). Multiplying those together, a red LED uses about 34 milliwatts (mW). Multiplying that by 24 hours in a day and 365.25 days in a year, a red LED uses about 298 watt-hours (Wh) a year of electricity. Since electric utility meters in North America typically read kilowatt-hours (kWh), that's about 0.3 kWh. If you're paying, say, US$0.10 per kWh, that means it costs about US$0.03 (i.e., 3 cents) to run a red LED for a year.
However, that's just the power for the LED itself. Since LEDs need to be supplied a limited amount of current, they are typically provided with a dropping resistor or some other power supply circuit which could easily consume more power than the LED itself. If you include that, the numbers are probably closer to 0.7 kWh per year and 7 cents per year.
