First, there is a real solar park -- Vandel 3 -- in denmark that uses less land than the difference between their claimed rooftop and ground values at 180ha for 150,000MWh or 12m^2/MWh. More sensible areas to use solar get over double that much sunlight.
Second even if we use their claimed 6W/m^2 that's still less area per person than the average american uses to park their car for world per capita average insolation.
It's a non issue.
- janef0421 4y agoThe issue isn't solely density, it's also site suitability.
- Schroedingersat 4y agoThe land in famously sunny UK presently used for ethanol crops alone is enough to provide 50% of their electricity. At a more realistic 20W/m^2 (about what you get on a random spot in the UK on average) you can provide the net electricity for 60m^2 per household. At a more realistic penetration just the roof area of occupied buildings is enough. The land use is a non issue. If you're really concerned about biodiversity just cover half of the golf courses. Solar farms are far better for diversity than pesticide and fertilizer covered monocrop grass.
