Bitcoin came along and offered a new way to create a money supply, based on currency going to whoever has bigger and more powerful specialized computers, technical knowledge, and ability to afford lots of electricity to mine BTC. It took the power away from the banking system, which was an improvement, but it still does not incentivize anything good in the world.

SolarCoin is a currency that is distributed as a reward for doing something that benefits the planet: generating clean renewable solar energy. We plan to put the reserve currency under smart contract so that the granting process can be automated. Before that happens, it is being held securely by the people who launched this project.
