I'm comparing two types of cabin illumination, and I'm having a difficult time to estimate the cost that will be saved by utilizing lights with a lower power consumption.
What are the costs of electricity on board an airplane? Basically, I am looking for the cost of a kWh of electrical power generated by the engine, during an average travel of about two hours.
I edit to any kind of airplane, because some aircraft are easy to find data. Some information I found already:
- In round numbers, a 737 will burn 5,000 pounds (750 gallons) an hour. (https://www.usatoday.com/story/travel/columnist/cox/2014/10/12/boeing-737/17036931/)
- An A320's two alternators can produce 150 kilowatts (kW) and needs only 50 kW in total. (https://www.safran-electrical-power.com/media/20151109_more-electric-aircraft-how-does-electricity-work-plane)
- The cost of fuel is approximately $1/gallon (https://www.airlines.org/argus-us-jet-fuel-index/)
If somebody have any idea, I would be very grateful.
