This helps to put things in perspective

We have had solar power technology since the 1800s. Early forms were concentrators that powered steam engines. Now we have advances in materials science, engineering, etc.

This image shows how much surface area it would take to power the World, Europe and Denmark, with current solar panel technology.

Contrast that with estimates of how much land has been ruined by tar sands, mountain top coal mining, toxic waste, etc.

Another thing to compare to would be the rough estimate of the reflective surface area required to counter the warming caused by green house gas pollution. Hint: It’s in the millions of square kilometers and it would need to be done in space.

It’s obvious to me that the Solar, Wind and other renewable energy technologies could easily do the job of providing power for our world. It’s just a matter of making the right choices.
