Renewable energy in New Zealand
Approximately 37% of primary energy is from renewable energy sources in New Zealand. Approximately 72% of electricity comes from renewable energy, primarily hydropower and geothermal power. This is expected to increase over the next 20 years, with wind energy making up much of that increase.
Renewable energy by type
Renewable electricity in New Zealand is primarily from hydropower. In 2011, 77% of the electricity generated in New Zealand came from renewable sources, a ratio that has been falling for decades while load growth has been met primarily by natural gas-fired power stations. In September 2007, former Prime Minister Helen Clark announced a national target of 90 percent renewable electricity by 2025, with wind energy to make up much of that increase.
Solar hot water
Installation of solar hot water heating systems is increasing in New Zealand due in part to government incentive schemes. High temperature system Solar thermal energy plants are not likely to be adopted due to the variable solar radiation in New Zealand. It is unlikely to be economically viable.
