Hope for a Change: Renewable Energy

The challenge of the century is the imperative to move to 100% renewable energy. This must happen in the next three or four decades as we approach three critical limits. First, the finite reserves of non-renewable's (fossil fuels and uranium). Second, increasing demand for energy. Third, increasingly destructive impacts from global warming. Combined these threats pose the greatest challenge ever faced by society. Our children's future depends on our rapid move to 100% renewable energy everywhere.
