The opportunities to diversify sources of energy and do so in a way that strengthens national security are very important. The challenge, as you know, with some forms of renewable energy—solar, for example—is that it's difficult to store electricity. It's very inefficient, very expensive to do so on a large scale.
From a perspective of the Canadian Armed Forces or U.S. military facilities, renewables are likely to be an important part of the energy puzzle, but not the whole answer.
Innovative approaches to fuel cells, other kinds of generating capacity—it is imperative to pursue those opportunities.
