We use 32 million ha of land globally (ca. 1 Germany) to grow plants for biofuels. This equals 1.400 TWh per year, or 4% of our global energy consumption for transport. If we&#39;d use the same area for PV, we could produce 32.000 TWh per year, already considering the potential yield for the areas where we grow bio fuel plants. For comparison: the entire world consumed 31.000 TWh of electricity in 2024. I love such comparisons. Source: https://www.youtube.com/watch?v=dQBgNpooCEo

The solution is definitely not to plaster the entire area with PV. It's just showing the mind-blowing contrast. Another great factor: If we electrify large parts of the transport sector, we reduce the energy consumption drastically.

@bastianallgeier — That seemed to be a similar story in this other video that was doing the rounds. Seeing these things always makes me wonder: do the people in control of these decisions just never see videos like this? Like, in Ireland, everyone’s up in arms about reducing petrol costs, and the govt is going to relax levies. But why not have been encouraging farmers to build solar farms? Is it because we don't have enough light? So frustrating! https://www.youtube.com/watch?v=KtQ9nt2ZeGM&t=2703s

@bastianallgeier It ought to be mandatory for all new buildings ) and renovations/upgrades) to have PV cells. Everywhere.

@bastianallgeier You probably already know this one, but I can really recommend this to everybody. He basically picks up that exact fact in the last part, as far as I remember. https://mas.to/@TechConnectify/115985224639778868
