Except you lose a lot of that power through attenuation. You can't really send electricity from the sahara to europe efficiently. Even over relatively short distances (a few dozen miles), you're losing up to 10-15% of your overall energy. A thousand miles or more...and I can't even find numbers on that because nobody does it.
- pfdietz 5y agoSince the total loss in the US grid is maybe 6%, your short range figure there cannot be right.

- notreallyserio 5y agoIs there some way to site manufacturing that requires lots of electricity (aluminum?) nearby? Maybe electricity could be exported by way of material.
- kenfox 5y agoYour 10 to 15% figure is total transmission and distribution loss from producer to consumer. If you scale up the transmission distance only, the total shouldn't change much. There are several studies referenced in this course http://large.stanford.edu/courses/2010/ph240/harting1/ http://large.stanford.edu/courses/2010/ph240/harting1/. Looks like 2 to 3% loss over 1000km.
- kwhitefoot 5y agoYou lose a few percent per 1000 km using HVDC. Even AC transmission doesn't have the losses you describe.
