Surface taken by solar pane?

[gagarine]

The model doesn't seem to take into account the land surface needed for solar panel or other renewable.

it depends on whether it is an important issue in your research. In China, we mainly use desert to deploy the solar panel for electricity and the building roof for solar heating water.

It's important in Europe, space is limited. Accessible areas are already mostly used for agriculture or housing.

If you want to produce a substantial amount of energy with solar, the needed surface can be enormous. If one want to use only solar energy to replace all other source of energy in Europe (oil, gaz, nuclear, ... ), it will be somethings like the surface of Germany (yes, the whole country).

In this condition, space is a key resource. It's also show things a bit more concretely.

Hi Simon I no longer work in the area of government responsible for this, but check out pages 215-220 of this document for some thoughts on this matter: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/68816/216-2050-pathways-analysis-report.pdf Regards Greg

@greg3000 thanks a lot, the document is very interesting. I arrive to the same kind of number than in the report-> you need at least around 100m2 of solar panel per capita to output the ~100Kwh/day consumed by person by day of total energy. But I think this is still it's very optimistic, if you do it for real it take certainly a lot more space.

I'm curious why the model was done in Excel.
