Burning wood == renewable, requires low investment. In fact, it's using Sun's energy captured some 100 years ago by natural means. Plant biomass, if left to rot, would release highly greenhouse methane (some 25 times as greenhouse-ish as CO2). Solar power == a lot of non-biodegradable waste from construction and decommissioning, requires high investment and constant maintenance, large infrastructure replace natural habitats (think rainforests and plains). Small solar devices are even worse in terms of environmental impact: manufacture, transportation and disposal of countless small units. </only slightly sarcastic>
