So less diffusion of oxygen into the blood Why is the volume of oxygen that has to be absorbed and the volume of CO2 that has to be removed large in mammals? (2)
A kilowatt-hour is the electrical energy consumed in one hour at the constant rate of one kilowatt. The average household in the United States uses about 8,900 kilowatt-hours of electricity each year.. Power is defined as the rate at which work is done or energy is consumed.
An average American home uses 40 kWh per day. Efficient homes use as little as 14 kWh a day, which includes winter heating (electric heat pump). Some off grid homes as little as 1 kWh a day! So, my consumption is right at slightly less than half the average American's and that seems about right considering there's just one person in the household.
