>What is the impact on people when their energy costs are raised? (Hint: energy - vast amounts of it - goes into everything, from growing food to producing artificial heart valves.)

There ought to be minimal impact on overall energy costs since renewable energy is capable of filling in the demand at the same cost these days.

Renewable energy is also perfectly capable of ramping up supply to match demand (unlike oil or gas there isn't a hard resource limit to manufacturing capacity).
