The two main sources of biomass for ethanol production are corn and sugar cane. Both take considerable amounts of energy, fertilizer, land, &c to produce - much more than just sunlight is required. The amount produced from other biomass is negligible and not likely to increase substantially.
In any case, ethanol is only a stopgap measure and not a long-term solution. Only real solution is a reduction in consumers of resources.
