Yes, wind and wave power are renewable; New Scientist pulls a Charlie Sheen

This study provides inaccurate and misleading information about wind energy and its physical interactions with the atmosphere for the following reasons. First, it states that the amount of power in the wind available for wind energy is 18-68 TW and that the climate effects of extracting all such power is equivalent to doubling carbon dioxide. However, wind power results in no net additional heat to the air since it replaces thermal power plants (coal, nuclear, natural gas), all of which directly add the same or more heat to the air than wind power directly through combustion or radioactive decay. These other sources also add carbon dioxide, which wind energy does not do during its operation. Even nuclear adds carbon dioxide continuously through uranium mining, transport, and refinement and, in its lifecycle, puts out 9-25 more carbon dioxide than wind. Second, even if wind...
