I don't think we have a clear picture of the energy sector two years down the road.

But another thought: some good may come of this. There'll be a universal need for energy-conserving technology. This will be the kind of society-wide shock to get people taking things seriously -- home insulation, turning down the thermostat, maximizing the number of solar installations in a neighborhood, letting homeowners sell their power back to the grid... It could be a once-in-a-lifetime opportunity, where people are desperate to consider and adopt new technologies.

For entrepreneurs, its' a chance to feel like you're helping not just some people, but the entire community, society in general -- and to feel like you're doing something especially meaningful. In the U.S. they've been talking up the chance to participate in the newly-established "Clean Energy Corps."

But you can chase the same highs as an entrepreneur.
