you forgot to add the most abundantly used renewable energy source to your list Gravitational Energy (hydroelectric). 90% of the electricity in my province is generated via this source.
nuclear is not renewable. Last I heard we have about a 150 years of currently economically viable fuel resources at current usage rates. There remains an estimated 1000 years worth of uranium in seawater and an estimated 500 years land based that are not currently economically viable. Though it is not renewable it is the lesser of two evils.
