Renewable energy in space

+0
−0

I'm working on a story set in a generation ship traveling through the stars. Its propulsion is a solar sail, which will accelerate it over many decades to a substantial fraction of the speed of light. However, its inhabitants need power for electricity, and don't want to use nuclear power (or radioisotope thermoelectric generators, RTGs), or fossil fuels.

Many spacecrafts today use solar panels or RTGs for power, but the latter is not renewable, and the former may not be useful when passing through regions of space where the light from stars is dim.

So, how can my ship be equipped to take advantage of renewable energy in space?
