Biomass Is More Efficient in Providing Energy Than Biofuels

Biomass is more efficient in providing energy than biofuels. Biomass uses a greater fraction of the crop than biofuels, and biomass produces more energy per acre of crop than biofuels. Yet, biofuels continue to be studied more extensively than biomass. Why does research continue to focus on biofuel optimization?

A) Biofuels are preferred because they do not release greenhouse gases upon combustion.
B) The US always has a surplus of corn that can be used to supply research on biofuels.
C) Biofuels are targeted for the transportation industry, a niche that biomass does not fill.
D) Scientists want to improve biofuels because the current biofuels leave behind a toxic waste when burned.
