NettetEnergy intensity is a measure of the energy inefficiency of an economy. It is calculated as units of energy per unit of GDP . High energy intensities indicate a high price or … NettetThe energy falling on the solar collector in 4 h in part is enough to be useful—for example, for heating a significant amount of water. Strategy (b) Taking a ratio of new intensity to old intensity and using primes for the new quantities, we will find that it depends on the ratio of the areas. All other quantities will cancel. Solution b
