Corporate Solar Co-op
If you live near a city or even a small town, there are large buildings everywhere and they all have tons of sunlight exposure. If you could put solar panels on all of those buildings and redirect the power back to the power company (let them figure out how to store it), it would be a win-win situation. We reduce some of our dependency on fossil fuels, the corporations that own the buildings save money on electricity, and we avert the next big energy crisis.
Reward: Some free solar panels for my house!
