So one train leaves San Francisco at 58 mph…
So if you are rusty, one kilowatt hour is using 1000 watts of electricity for an hour. In their hypothetical, electricity costs $.10 per kilowatt hour (kWh). 10 million kWh at $.10 a kWh would be $1 million, nut $100,000. Something is not adding up.
The three stations involved are
– an AM daytime only AM station at 400 watts
– one FM station at 100,000 watts
– two FM stations at 50,000 watts each
– 7 other FM signals totaling about 16,000 watts
With the exception of the AM station, the transmitters are on 24 hours a day. The average cost of electricity in Michigan is $.13 an hour. All of the stations are in Michigan.
How much power are they actually using per year and how much does it cost?
