How many solar panels would it take to power the world?

Interesting food for thought on how little it could take to do so much.

Was this post interesting? Please share it!

You’re right. It’s still 15 times my country though, so I guess it would be super expensive (?)

Not only very expensive… Did you thought about the CO2 and all the chemical waste which would be produced by making such an amount of solar panels.

And what’s about all the batteries we need to store the energy for using during the night?

And what’s about the long (very long) power lines from the Sahara to Western Europe?

At the end, it’s not that easy…

@Xolum Thanks for the comments about solar panels — you bring up some great points, but maybe the waste is a lot less than water dam technologies?

Or how about Wind Technologies?

There is nothing wrong with your comment.

I just have to approve all new commenters.

Sorry, I didn’t notice the approval procedure.

I think, a mix of solar power, wind technologies, geothermal energy and hydropower will help us a lot to save the world, but we will need also oil, coal and gas for a long time. So a lot of research power should be put into developing power saving technologies!
