Renewable energy

Medium and large-scale hydro electricity generation, and geothermal power provide much of New Zealand’s electricity. They are often referred to as “traditional” renewable energy sources.

In contrast to fossil fuel energy resources, they provide a continuing supply of energy from a source that is available on an ongoing basis. There is, however, considerable debate about the “sustainability” of both of these traditional renewable forms of energy, as they can both result in adverse effects on the local environment.

A new range of “non-traditional” renewable energy sources is being investigated and developed. Non-traditional renewable resources also include traditional resources exploited in different, and often more efficient, ways (for example small-scale hydro electric or geothermal developments).

Together these resources are now described as new renewable energy resources. They include wind, solar, biomass, and tidal and wave energy.

Renewable energy target

Renewable energy resources have a major role to play in meeting our demand for energy. New Zealand has a goal of increasing renewable energy supply by 22 per cent by 2012.
