Powerful: Energy for Everyone (DVD)

Challenging where our energy comes from and who profits from it can seem a little eccentric After all, not everyone has solar panels bolted above the doorstep. Green economy educator David Chernushenko does, and they generate more than enough energy to go around. So why can't he share it? New technologies mean that energy security is within our grasp, but harsh resistance is still being met. Debunking some of the spin of the big energy lobby, David embarks on a global journey to discover what a sustainable future might actually look like.
