"If we had the winds of Texas or the sun of California, the task here would be even easier," said Felix Matthes of Germany's renowned Institute for Applied Ecology. "Given the great potential in the U.S., it would be feasible there in the long run too, even though it would necessitate huge infrastructure investments."
Germany currently gets 23 percent of its energy from nuclear power — about as much as the U.S. Its ambitious plan to shut down its reactors will require at least euro150 billion ($210 billion) investment in alternative energy sources, which experts say will likely lead to higher electricity prices.
Many decades-old reactors are highly profitable as their initial cost has been written off, but they now face higher costs as regulators push for safety upgrades in the wake of the Fukushima disaster. One of the most pressing — and costly — requirements is likely to be a mandatory upgrade to reinforce all nuclear power plants' outer shell to withstand a crash of a commercial airliner.
