Always the perennial third in the national ratings, ABC News president Roone Arledge reformatted the program, relaunching it as World News Tonight on July 10, 1978. Reynolds, who was demoted when the network hired Reasoner, returned as lead anchor, reporting from ABC News' Washington, D.C. bureau.
The correct unit for measuring energy capacity of a battery product is called watt-hours. Watt-hours signifies that a battery can supply an amount of watts for an hour. For example, a 60 watt-hour battery can power a 60 watt light bulb for an hour. The same battery would run a 5W phone for 12 hours and power a 1W LED light bulb for 60 hours.
Do not add appliances that should be propane fueled. Then multiply listed watts of each appliance by the number of hours per day, on average, that appliance runs. This gives watt-hours per day for that light or appliance. Do this for each appliance. The total for all appliances is your total watt-hours needed each day.Figures below show some appliances commonly used in independent solar homes. Substitute your own daily hours for each and add other appliances not listed. Refrigerators come on and off on demand by thermostat, so running time per day is not known. Our Kill-a Watt meter will accurately test watt-hours used per day for any AC appliance up to 1875 watts.
