Energy derived from solar power, wind power, a fuel cell, methane
gas from landfills, ocean thermal power, wave or tidal power, low-emission
advanced renewable energy conversion technologies, a run-of-the-river
hydropower facility provided such facility has a generating capacity
of not more than five megawatts, does not cause an appreciable change
in the river flow, and began operation after July 1, 2003, or a sustainable
biomass facility with an average emission rate of equal to or less
than 0.075 pound of nitrogen oxides per million BTU of heat input
for the previous calendar quarter, except that energy derived from
a sustainable biomass facility with a capacity of less than 500 kilowatts
that began construction before July 1, 2003, may be considered a Class
I renewable energy source; or
