“In (largely) gloomy Germany the area needed by PV panels to supply all electricity generation (nearly 560 TWh in 2012) would be considerably larger. With an average PV output of 100 kWh/m2 (the recent annual mean for both roof - and ground-based installations), it would require about 5,600 km2 covered with modules. That would be the equivalent of nearly 1.6% of Germany's total area, 25% of the country's built-up area, or almost 15% of land claimed by settlements and transportation infrastructure; and roughly 2.7 times the total area of all German roofs, based on an estimate of roughly 25 m2 of roof area per person (Waffenschmidt 2008).”

“When we hear the phrase ‘clean energy’ it normally calls to mind happy, innocent images of warm sunshine and fresh wind. But while sunshine and wind are obviously clean, the infrastructure we need to capture it is not. Far from it. The transition to renewables is going to require a dramatic increase in the extraction of metals and rare-earth minerals, with real ecological and social costs.”
