That's an incredibly low amount. Taking Berlin as an example, even 5000km lets you reach plenty of hot, sunny desert areas where any losses will be easily offset by vastly increased solar efficiency. Or you could spread out your wind energy sources to get more consistent coverage.
In fact that's pretty much what Singapore is doing: building a solar farm 5000km away in Australia.
- cinntaile 5y agoHVDC brings that down to about 3,5% per 1000km even.
- midjji 5y agoThey might be, but if so, that power is exclusively used in australia^^ 1000km of ocean reduce transmission to about 0.1%^^
- adgjlsfhk1 5y agothis was true with ac power cables, but isn't with hvdc ones. they don't have the same capacitance issues, and add such undersea cables are becoming more prevalent. a 1400km between Egypt and Greece is expected to be completed in 2023
