True. Today, and probably in the next couple of years. But in 10, 20, 40 years? Hopefully not so much any longer. I firmly believe in the power of engineering research and given humanities history in solving engineering challenges, we will also solve this one. If we will end up with reliable long distance cables, or some form of energy storage I have no opinion on, only the future will tell us.
