Sea access should do... But really, why would you only invest in renewable energy at home. We should be building a solid grid and just hook up sun farms and wind turbines where we get the best return on investment. Relying my hydro from Norway to cover days with little wind should work fine. Note: you won't want to have wind turbines close by regardless, put them at sea :)
