(with Examples) 1  An abstract noun is a word which names something that you cannot see, hear, touch, smell, or taste. It is the opposite of a concrete noun. 2  It is not always easy to spot an abstract noun, and it is common for grammarians to argue over whether the thing represented by a noun is perceivable or not.
Household electricity use: 6,000 kWh per household per year for 3 residents average per household. So the household use per capita is 2,000 kWh or about of per capita electricity from all applications. Household Natural Gas use: 400 therms per household x 30 give 12,000 kWh equivalent electricity.
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.
