According to the Energy in Aotearoa | New Zealand report in 2021,
Two new wind farms were brought on-line with 223 MW in generation capacity
28.4% of energy consumption came from renewables
Wind turbines generated enough electricity to power around 360,000 homes
There were 28,212 EV's in Aotearoa | New Zealand at the end of 2021
68% of refined oil products came from Korea and Singapore
Aotearoa | New Zealand consumed enough petrol to fill 1,160 Olympic sized swimming pools in 2021
Coal imports reached a record high of 1.8m tonnes
National energy consumption increased in 2021 but did not return to levels seen before the beginning of the COVID-19 pandemic. The share of total energy supply from renewables was at its highest level since reporting started in 1990, at 40.8 per cent.
Natural gas production fell 13 per cent in 2021 because of lower output from the Pohokura field. The combination of low lake levels and the fall in natural gas production saw coal use for electricity generation increase by 29.5 per cent. Despite high coal use for electricity generation, the renewable share for electricity generation increased to 82.1 per cent for 2021, up from 81.1 per cent in 2020.
During 2021, Aotearoa | New Zealand became a net importer of energy. While crude oil is produced in Aotearoa | New Zealand, nearly all of this is exported as it is not suited to current refining capabilities and can achieve a higher price on international markets. Each year approximately half our national coal production is exported. Aotearoa | New Zealand imported 69 per cent more coal compared to 2020 and became a net importer of coal for the first time since reporting started. Imports of oil and oil products decreased by 4 per cent, which is the lowest amount since 2002. The national average of self-sufficiency was at its lowest level since reporting started in 1990, at 72.4 per cent in 20211. This was driven by decreases in the self-sufficiency of oil and coal.
National energy consumption increased by 0.7 per cent compared to 2020 but was still down 6.6 per cent compared to 2019. The greatest increase in 2021 was in the transport sector. Residential consumption in 2021 increased 1.5 per cent compared to 2020 and 3 per cent since 2019. Use of both electricity and natural gas increased 5 per cent compared to 2019. Energy consumption for transport peaked in the June quarter as Aotearoa | New Zealand started quarantine-free travel with Australia on 19 April 2021.
National energy intensity has improved by an average of 1.5 per cent per annum between 1990 and 2019. Energy intensity for all sectors decreased this year, with the biggest decrease in chemicals and metals which decreased by 11.2 per cent compared to 2020.
