The proportion of electricity generated from renewable sources is inching upwards.
New figures from the Ministry of Economic Development show that electricity from renewable sources accounted for 77% of total electricity generated last year, compared with 74% the year before.
The Government has a target of 90% renewable electricity by 2025.
Renewable electricity comes mainly from hydro, wind and geothermal energy, as opposed to electricity produced by burning fossil fuels.
The figures also show total electricity use fell 1% last year, compared with the previous year, because the Canterbury earthquakes forced many businesses to shut down or reduce their activity.
Greenhouse gas emissions from the electricity sector also fell last year but remain well above 1990 levels.
