A typical household electric space heater consumes about one kilowatt of electricity.

Individual consumption was used as the measure, often cited because it includes all goods and services that a household consumes, regardless of whether they pay for them.

Another source says that each household consumed 7,100 kilowatt-hours annually in 2008.

In the same year, the average American household consumed more than twice that, or 10,655 kilowatt hours, according to the Energy Department.

Studies reveal that households in Kosovo consume 7.58 m of wood each during one year, or a total consumption of 1.525 million m per year.

By contrast an average native Canadian household paid $20,259 in tax and consumed $10,102 dollars in services.

For example, households may consume more (or save less) in response to their greater wealth due to rising stock or housing values.

If a household consumes less than the free basic water limit, the share is obviously zero.

So, while American households consume 20 percent less energy on average than they did 30 years ago, the trend in recent years has been toward more energy use.

In Africa, the report found, the average household consumes 20 percent less than it did 25 years ago.
