Wind power
Using wind to generate power is not as difficult as one might assume especially when there are a lot of references to cite.
From small distributed systems used in homes and small offices to large wind farms generating and providing power to villages and cities the story is the same. Wind power is both feasible and cheap.
However, emphasis will be placed on access to raw materials and components used in the manufacture of wind turbines to promote local manufacture while guaranteeing ready support for the solution once deployed.
