Energy transformation refers to the conversion of energy from one form to another. It includes electricity generation, petroleum refining and other transformation (including coal used for steel production). Electricity generation is the main form of energy transformation in New Zealand and comes from a range of energy sources. In
2010, a net total of 156 PJ of electricity was generated, 74% of which was from renewable sources. Hydro was the major source of electricity generation at 56%, followed by gas at 21%, geothermal at 13%, with coal, wind, wood, biogas, oil and waste heat making up the balance. 2010 saw the lowest generation from coal since 2002.
In 2010, 98% of refinery input was from imported crude and feedstocks, with the remaining 2% from indigenous crude and condensate.
Methanol production from natural gas by Methanex remained high in 2010, so total fuel used as a feedstock for petrochemical production (including ammonia/urea production) remained around 25 PJ. Although methanol can be combusted for energy purposes, the methanol produced in New Zealand is mainly used as chemical feedstock (e.g. to make plastic).
Gas combusted during the production of petrochemicals is included as industrial sector demand within total consumer energy. Only gas used as a feedstock (and therefore not combusted) in petrochemical production is classified as non-energy use.
Like TPES, consumer energy in 2010 was dominated by oil at 46%. This was primarily oil used for transport purposes, although oil is also the dominant energy source used in the agriculture, forestry and fishing sectors. The other major contributor to TCE was electricity, which made up 27% of final consumer demand in 2010. Electricity is the dominant consumer energy source for industrial, commercial and residential consumers.
Figure A.3a: Total Consumer Energy by Fuel for 2010
Non-energy Use Non-energy use refers to use of fuels to produce non-energy products. Non-energy products are products where neither the raw energy source used to produce the product nor the product itself are combusted. Examples include bitumen for roads and lubricants produced by the New Zealand Refinery Company, and petrochemical production from natural gas.
Consumer Energy Demand Total Consumer Energy (TCE) is energy used by final consumers. It excludes energy used for energy transformation (e.g. electricity generation) and that used for non-energy purposes. Compared with 2009, New Zealand’s TCE increased by 2.0% to 531 PJ in 2010. Figure A.3a details the shares by fuel type for 2010. Figure A.3b shows a time series of consumer energy by fuel since 1990, with the corresponding data in Table A.3.
TCE by sector is shown in Figure A.4a and Figure A.4b for 2010, with the corresponding data in Table A.4.
