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.
The average electricity consumption is 4,800 kWh per household [36]. A smaller than average household is taken arbitrarily to be 3,000 kWh (i.e. roughly two-thirds of the average), and a larger than average household to be 7,000 kWh (i.e. roughly 50% more). Mark Linas [6] makes the following suggestions: small house: 1,650 kWh; medium house: 3,300 kWh; and mansion: 5,000kWh.
