Be prepared for Saudi Arabia to continue its dominance in world energy markets. Most of Saudi Arabia's 840,000 square miles is desert, perfect for capturing solar energy. And aside from the distinct possibility of a relatively weak world economy, there should be no shortage of capital moving into renewable energy as the price of petroleum continues to increase. Transferring the energy to places that need it will be the hard part, particularly to nations on the other side of the world. Considering the density of batteries, I'm not sure how feasible it is to carry batteries on a boat. I'm also not sure how feasible it is to have wires carry high-voltage electricity across the Bering Strait, if land transfer made more sense, particularly considering how far the electricity would have to travel if it came from the desert.
