The BIGGEST problem with clean energy

There are many problems for that global goal, energy storage in comparison to the political and economic challenges will be easy. How would you incentivise or compensate the inventors of these technologies to provide them to developing countries who otherwise cannot afford to procure or implement the infrastructure needed?

It's an interesting video, but another slant on this would have been talking to these companies about their financial models and business ethics as well.
