> Cranks and pedals are not a solution at all if we decide to cling to an energy-intensive lifestyle - but then, neither is any other renewable (or even non-renewable) energy source. The main problem with our approach to pedal powered machines is that we compare them to fossil fuel powered machines and not to the inefficient human powered tools and machines that went before them.

I’d prefer to take my renewable energy with no quality of living sacrifice, thanks.
