Consider the Lobster and Electricity: Helping Meet the Energy Challenges of Maine's Small Islands

Most island communities do not have economies of scale or local fossil fuel resources, two key factors contributing to significant increases in energy costs relative to mainland peers. A case in point is two islands located off the coast of Maine—Isle au Haut and Monhegan, both of which are currently weighing their energy futures.

Forestry residues, switchgrass, and corn stalks are all examples of non-food biomass that can be used to make biofuels and bioproducts.
There Is a Cornucopia of Feedstock Options for Making Biofuels

Right now, biofuels and consumer products made from biomass are not commercially widespread. However, the Energy Department’s Bioenergy Technologies Office (BETO) is funding research and development to help lower their costs so that private industry can produce and sell them on the commercial market.
