Three recent news items remind us that energy transitions take time, a lot of time--far too much time to be shrunk down into a television special, a few talking points, or the next big energy idea.
For example, the complex management task of putting together the international fusion research project called the International Thermonuclear Experimental Reactor (ITER) has resulted in estimated final costs that have tripled since the 2006 launch. Fusion could theoretically offer clean and abundant energy almost indefinitely because it uses ubiquitous hydrogen* as fuel and creates helium in the process. (Water you'll recall is two hydrogen atoms and one oxygen atom and is therefore the most abundant source of hydrogen.)
Despite nine years of effort, ITER has yet to carry out a single experiment; and, the project is not expected to do so for another four years. The idea for such an international project was hatched in 1985 during a summit between U.S. President Ronald Reagan and Mikhail Gorbachev, the leader of what was then still called the Soviet Union. Thirty years later fusion is still receding into the horizon of our energy future.
