Answer:
approximately 1.355 million households can have their total electricity needs provided by landfills in the United States.
Step-by-step explanation:
To calculate the number of households that can have their total electricity needs provided by landfills in the United States, we'll need to convert the annual electricity production from kilowatt-hours (kWh) to kilowatt-days (kWd). Then, we'll divide the total electricity production by the average daily electricity usage per household.
1. Start by converting the annual electricity production from kWh to kWd. Since there are 365 days in a year, we'll divide the total annual electricity production (15 billion kWh) by 365:
15 billion kWh / 365 = approximately 41.1 million kWd per day
2. Next, divide the total daily electricity production from landfills (41.1 million kWd) by the average daily electricity usage per household (30.3 kWh) to find the number of households that can be powered:
41.1 million kWd / 30.3 kWh = approximately 1.355 million households
