As the largest Māori commercial forest owner in New Zealand, Ngāi Tahu Forest Estates is keen to ensure a sustainable future. It is working with Development West Coast in the hopes of establishing additional bioenergy plants there, starting with a feasibility study. Bioenergy, as the name suggests, is energy from biological sources like wood and other plant materials, and can be used as a solid, liquid, or gas. It is renewable, unlike finite fossil fuels such as coal and oil. It is the most-used renewable energy globally, ahead of hydroelectricity and wind. It has become a major industry in many European countries and there is potential for this to happen in New Zealand as well.
