Personal Energy Consumption By Jeremy Larsen
Household Energy Consumption The household sector is responsible for about 15 to 25 per cent of primary energy use in OECD countries and for a higher share in many developing countries. Average per capita household energy use in developed countries is about nine times higher than in developing countries

Vehicle Energy Use
Energy Use by End-Use Sector Transportation Industrial Commercial Residential Transportation sector use of energy experienced tremendous growth overall, but registered noticeable pauses in 1974, , 1990 and 1991, and In 2004, petroleum accounted for 97 percent of the sector’s energy, and motor gasoline accounted for two-thirds of all petroleum used in the sector.

If we really want to see change? It is what no one wants to hear but we will have to give up some things rather than always getting more.
What is wrong with us?
Energy Savings If we could actually cut our household energy usage in half… Current Average Household Energy Usage = 35 GJ 9730 kWh/2 = 4865 kWh 35 GJ = 9730 kWh 4865 kWh * $0.09 = $ saved per year per household. $ * 105,480,101 households in the year 2000 = $46,184,462, saved per year 17.5 GJ * 105,480,101 households in the year 2000 = 1.85x10^18 J or 5.13x10^ 11 kWh saved per year
