“Oil contains an enormous amount of energy. A very small tea-cup of oil, 100 ml, contains energy equal to one kilo-watt-hour, 1 KWh, and what can you do with one kilo-watt-hour? If you place a small car, 1.200 kilo, at the base of the Eiffel Tower and tie a rope to the car, and then take the elevator to the top of the tower, 321 meter. By hand you then pull the car to the top of the tower, and when you have done this you have done a work equal to one kilo-watt-hour.”“Driving a SUV one mile uses the same energy as pulling a SUV to the top of the Eiffel Tower.”
