I like your Ocean thermal energy conversion. Cool idea. (Pity the largest plant in operation is only 10MW, hope they develop this a lot more.) Hydro is cool as well, hope we get the lines up to the DRC, that can provide some serious clean power. (The lines are unfortunately expensive, but definitely feasible.) I like Biogas and Biomass. Those cow poo power to the BMW factory is a really cool idea with my total endorsement, and I am enthusiastic about such initiatives. (But with 30,000 heads of cattle needed to produce 4.4MW for the factory, I would not like it to be a big source of  baseload power.) And our country has enormous potential for concentrating solar plants with thermal (CSP), I enjoy reading of each plant being opened. (Typically 50 or 100MW.) However, nuclear, properly managed, is still the greenest option. (Half the price of typical CSP.)
