Yes Power density is the rate of energy generation per unit of land surface area occupied by an energy system. The power density of low-carbon energy sources will play an important role in mediating the environmental consequences of energy system decarbonization as the world transitions away from high power-density fossil fuels.
When measured using the methods presented, solar energyhas a density of1.5 microjoulespercubic meter, overtwentyquadrilliontimes less thanoil. Humanenergydensityisapproximately1000J/m3, whileotherinexhaustiblessuchas wind and tidal have energy densities of 0.5 to 50 J/m3.
The power density of solar and wind power remain surprisingly uncertain: estimates of realizable generation rates per unit area for wind and solar power span 0.3–47 W e m −2 and 10–120 W e m −2 respectively. We refine this range using US data from 1990–2016.
Median, mean, and uncertainty estimates are provided for 177 different densities from the literature. Non-renewable power densities are found to be three orders of magnitude larger than renewable densities. Natural gas and solar energy yield the highest median density per non-RE, and RE system respectively.
