Considering that the vast majority of a plant's biomass is lignocellulose there's much more potential to create ethanol from cellulose rather than starch. This whole process hinges on being able to convert the cellulose to a fermentable sugar and there's a few ways to accomplish that. Perhaps the best way is enzymatic using fungus or bacteria produced enzymes from cow/termite/whatever.
There are much better things than a kernel of corn for making ethanol if you can devise a cheap way to break down cellulose. Currently, most research is based on switchgrass, but I believe hemp was the highest (land based) autotroph in regards to shear biomass.
As long as we can keep growing vegetation that we can use for burning, then biomass will be reliable.
biomass
because it is
organic matter in it

the sources of biomass energy are garbage, wood, waste, landfill gases, and alcohol fuels.
Yes, the energy contained in biomass is that gleaned from the Sun by living things.
The sun. Biomass could not have grown without sunlight.
One reason why biomass energy is not a good energy source is that a large amount of land is need to create enough electricity to make biomass efficient. Another reason is that it can consume more fuel.
Fuel companies rely on this energy source to power things up. Automotive industries also rely on thin energy source(biomass).
Any energy source that is obtained from animal or plant matter, excluding fossilised material, is considered biomass energy. So, anything that's not that, including oil, coal, gas, and nuclear energy.
