Yes, there are areas, but the challenge is putting the entire package together. There is LED full spectrum lighting. Universities are studying that, but truly, I believe if you are going to solve the food security problem, you need to solve two things first: cold climate housing and alternative energies. We cannot continue to burn diesel in the north. It's too expensive. There are other mechanisms for alternative energy: wind, solar in some areas of the north, not the far North, but if you build a building efficiently so it requires very little heat, then you need very little energy to heat, and that is where we have to start.
