Land use intensity is an important impact because it is often used as a proxy for other impacts. Land-use intensity may be quantified by the following metrics: (i) land area “transformation” per unit of time-averaged power output (km2 GW−1) or per nameplate “peak” capacity (km2 GWp−1), (ii) land area transformation per unit of electric energy generated (km2 TW h−1), and (iii) land area “occupation” per unit of electrical energy generated (km2 yr TW h−1). The metric “transformation” focuses on the one-time action of changing the physical nature of the land, i.e., installation. Alternatively, the metric “occupation” is a measurement of land being used for a known period of time, defined as land area multiplied by the length of time that the land area is held in use. The length of time needed for the land to recover from use should be included in this length of time. The occupation metric captures the impact from both the installation and operation phases, whereas the transformation metric captures only the installation phase.
