From the DESERTEC website:
> For long transmission distances direct current transmission is superior to alternating current. Alternating current has high losses due to capacitive and inductive resistance, which do not occur in direct current transmission. With that technology, a 3000 km line (for example Cairo to Munich) has losses lower than 10%.
If the energy is practically free from the sun then 30% loss can be manageable if that's the cost of renewable reliable energy. Heck coal is only about 44% efficient to begin with and we currently accept that loss.
Over large distances, high-voltage direct current transmissions would be used which has losses in the low single-digit percentage per 1000km. See following link for details:

And for wind, it's the same issue, when there is wind in Finland, there is wind in Spain. So you can't "balance thing" between countries.
