what's interesting about this is that it represents a range of predictions from everyone from fossil fuel companies to government agencies and NGOs - but you can see that in almost every scenario the vast majority of both the increase from current day (2022ish) is handled by some mix of solar, wind, hydro, and nuclear with most scenarios relying most heavily in solar and wind. none of these scenarios has an offshore wind farm the size of russia, nor a solar farm the size of china. in fact, it only takes a tiny portion of the earth's area to meet a huge fraction of our energy demand with current solar tech. if you didn't look at the previous map, which had lots of citations and sources from, again, actual scientists, here's another analysis which has been widely shared and analyzed. this is solar electricity for the entire world as of around 20 years ago. of course the numbers are different now and power demands increase, but it's not an order of magnitude difference, and we have the whole planet, not just algeria...
