Renewable energy
Renewable energy is energy made from self-restoring natural resources, creating no or very small amounts of greenhouse gas emissions. It can be generated from bioenergy such as wood or animal residue, the wind, sun, rivers and lakes and geothermal resources. 40% of NZ's energy comes from renewable sources and 80% of NZ’s electricity comes from renewables.
Businesses can reduce their carbon footprint by converting to renewable energy sources such as wood, or by generating their own. Using renewable energy may improve your brand and company reputation – many New Zealanders make purchase choices based on a company's environmental and social profile.
