  Incandescent light is generally better for the environment though (IIRC LowTechMagazine did the math for this)

  Candles generate soot, which is not good for your health. The soot will also stain walls and ceilings, similar to cigarette smoke. Natural waxes like beeswax candles have a cleaner burn, but they're very expensive. If you're going to go non-electrical, I think an oil lamp (e.g. paraffin) is your best bet. Very cheap, safer than candles in the right lantern, and clean-burning (assuming a quality oil that doesn't have a lot of sulfur and other pollutants).
