Outputs from the Christchurch Energy Database are many and varied based on the requirements of the database user. Some typical database outputs are given below.
CHRISTCHURCH PRIMARY ENERGY SOURCE
Christchurch renewable energy content was 38.1% in 2008, 39.6% in 2009 and 38.6% in 2010. The renewable energy component is highly seasonal, responding to higher energy demands in winter.
CHRISTCHURCH ENERGY SUPPLY BY TYPE
Christchurch energy supply is predominantly comprised of electricity and the traditional fuels used for transportation, petrol and diesel. Whilst other fossil fuels and biofuels contribute significantly to the total, solar energy has no significant impact at this time.
CHRISTCHURCH ENERGY DEMAND BY SECTOR
Christchurch’s energy demand by sector also reflects the increased heating requirement in winter. The commercial sector includes the institutional sector.
This data has been derived from the EECA End Use Database filtered by sector for Christchurch City, with adjustments made based on recent market data and intelligence. Enhancements to this methodology will be on-going as Statistics New Zealand progress their economy wide energy use surveys, EECA update their End Use Database, and access is gained to more detailed sector breakdowns.
CHRISTCHURCH OVERALL ENERGY TREND
Christchurch’s total energy use has not grown substantially since 2008, but has reduced by approximately 8.3% on average following the February earthquake.
CHRISTCHURCH ELECTRICITY COMPOSITION
Christchurch electricity is almost all from hydro energy sources, and hence substantially renewable. The only period in the database timeframe when the renewable content of Christchurch electricity reduced significantly was May to August 2008, resulting from reduced inflows to South Island hydro storage in autumn 2008 causing high electricity inflows to the South Island via the HVDC link.
CHRISTCHURCH LAND TRANSPORTATION SECTOR
The energy used in Christchurch for land transportation is remarkably static across the database timeframe.
