Land is reusable (think recycling) but not renewable. Natural land creation happens in geological time scale, so pretty much like new fossil fuels.

@kmic

The core problem here is that large-scale PV farms will always compete for sunlight with equally or more needed environmental uses. Land in densely populated places that is not used for housing is used for farming, and what is not used for farming is used for recreation and nature reserves.

This was precisely the point of recent protests against a PV farm in Kent where they essentially wanted to cover 7 ha of meadows and forest with PV panels.

@kmic

Residential PV does reuse the space on roofs, parkings or other spaces that does not require sunlight. Residential PV has however other problems which make it of little use for supplying power to industry for example.

@berkes

I don't ignore anything, I state the fact supported by the scientific data. Now *where* exactly you find that extra space is another topic and yes, residential solar panels do solve this challenge to some extent even if they have other issues.

In case of Google it's most likely due to prevent free programmatic use of their search engine which they also sell as a paid API.

From my perspective it's not about scraping bots but about spam bots - you put any contact or registration form on the web, and within a week you start getting tons of spam messages every day.

@amici

And your second argument is not true either. Solar panels compete for sunlight with both plants and humans. Large solar farms in densely inhabited areas are an obvious residential and environmental concern. Wind farms are noisy and require that no trees are growing around, which was precisely the reason why they faced opposition in Sweden when they were forcing deers migrating away due to the noise.

@amici

The reason this might be counter-intuitive is a widespread misconception that solar panels somehow arrive to this world made of pranic energy and just magically appear on the target site.

Unfortunately this is not the case. Solar panels are made entirely from metals that are mined, mining of which (especially cadmium, rare-earth metals) produce huge amounts of toxic waste which needs to be processed and stored.

@amici

If there's a scientific paper whose conclusions are not intuitive for you, your first reaction should be to read methodology rather than rather arrogantly rant about "bullshit".

Because your first question is already answered in the article and yes, the land usage already includes mining, manufacturing etc.

It's actually quite ironic that renewable energy activism tends to completely ignore one critical resource it uses that also happens to be non-renewable: the land surface.

The challenge here is that the best renewable energy source (solar) uses three orders of magnitude (1000x) more land than the best non-renewable (gas).

To replace gas with nuclear you need pretty much the same area. But to replace gas with solar you suddenly need to find 1000x more extra space.

A very interesting paper that looks at world economy and power consumption

Civilization networks grew from efficient past production. Energy sustains circulations along these networks. The ratio of GDP (or Y) to Energy consumption has increased as we've become more energy efficient. But cumulative GDP and Energy consumption has been tied by λ /2
