In New Zealand 70% of the country’s electricity generation is already renewable. Plant biomass can be used for multiple forms of bioenergy, and there is a very large potential supply, depending on which global assessment is most accurate in terms of land area that could be available for biomass production. The most suitable plant species must be identified before the potential biomass production in a particular region can be quantified. This in turn depends on the degree of climatic adaptation by those species. A review article by Kerckhoffs and Renquist identified the most suitable crop species and assessed their production potential for use within the climatic range present in New Zealand.
