The electricity sector in New Zealand uses mainly renewable energy, such as hydropower, geothermal power and increasingly wind energy. As of 2021, the country generated 81.2% of its electricity from renewable sources. The strategy of electrification is being pursued to enhance the penetration of renewable energy sources and to reduce greenhouse gas (GHG) emissions across all sectors of the economy. In 2021, electricity consumption reached 40 terawatt-hours (TW⋅h), representing a 0.2% increase compared to the consumption levels in 2010.
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the power grid.
The electricity sectors of the Republic of Ireland and Northern Ireland are integrated and supply 2.5 million customers from a combination of coal, peat, natural gas, wind and hydropower. In 2022, 34 TWh were generated. In 2018 natural gas produced 51.8%, while wind turbines generated 28.1%, coal 7%, and peat 6.8% of Ireland's average electricity demand. In 2020 wind turbines generated 36.3% of Ireland's electrical demand, one of the highest wind power proportions in the world. While the United Kingdom was one of the first countries in the world to deploy commercial nuclear power plants, the island of Ireland has never had a nuclear power plant built on either side of the Irish border. Nuclear power in Ireland was discussed in the 1960s and 1970s but ultimately never phased in, with legislation now in place explicitly forbidding its introduction.
