Though Monbiot is cited in the original article, he doesn't really understand vertical farming. Not only are energy costs plummeting (which he doesn't address), but not all vertical farms rely on artificial light. Click back into the article and check out Sky Greens.
- maliker 11y agoElectricity prices have been rising steadily for years. And this is before any serious attempts to reduce carbon emissions, which is expensive. Source: http://www.eia.gov/todayinenergy/detail.cfm?id=20372 http://www.eia.gov/todayinenergy/detail.cfm?id=20372 For vertical farms that only use natural light, they only collect light equal to the building surface area (actually it's a bit worse on the sides). So, it would work fine for just the top story of the building plus a few crops on the sides.

- giltleaf 11y agoI definitely misspoke, my bad. I mean that the cost, in terms of energy requirement, required to produce light is going down. Source: http://www.eia.gov/todayinenergy/detail.cfm?id=15471 http://www.eia.gov/todayinenergy/detail.cfm?id=15471
- hanniabu 11y agoI used to work for a company with a very mechanical system similar to Sky Greens (City-Hydroponics) and the costs end up being transferred into maintenance. All those moving parts cause a lot of problems.
- giltleaf 11y agoThat is an interesting comment and something that doesn't often get brought up. Thanks for pointing that out.
