Renewable energy is used throughout New Zealand. Hydro systems, New Zealand's largest renewable energy source, generate around 60 - 70 per cent of the country's electricity and is available on an ongoing basis. New Zealand's unique geographic characteristics allow a number of renewable energy sources to be utilised - including the five sources shown on these stamps, hydro, geothermal, wind, biogas and solar.
The ideal promoted by this stamp issue is to have New Zealand totally free from burning coal of gas to generate electricity for our energy needs.
