Energy intensities

Energy intensities describe the amount of energy needed to produce one unit of action or work, or to carry out an activity. Reducing the amount of energy used per unit or activity (improving the energy efficiency), reduces the energy intensity.

For instance, electric cars are much less energy intensive (0.226 kWh/km) than diesel engines (0.661 kWh/km).

If we have the city’s Operations (number of diesel cars) multiplied by the Energy intensity (of a diesel motor) we can calculate how much energy and what sources of energy the city is using.
