Total energy consumption

Why we monitor total energy consumption

Energy is an important component of our everyday lives. We use energy to heat our homes and our water, to cook our food, to run appliances and for transportation. Energy is also vital to industry and the economy of the country.

Energy can be produced from renewable and non-renewable sources. It is important we use our resources carefully to ensure future generations can meet their energy needs. Inefficient energy production and use results in natural resources being used at a greater rate than is needed. This affects our region’s natural and physical resources. Inefficient use of fossil fuels also gives off greenhouse gases, which affect our environment.

However, electricity generation from renewable sources can also affect the environment. For example:

  • productive land is lost when hydro dams are built and river valleys flooded
  • native fish are unable to migrate up rivers with hydro dams
  • wind farms create noise issues for neighbouring residents.

We need to sustainably manage both our renewable and non-renewable sources of energy.

Waikato Regional Council measures the amount of energy consumed in the Waikato region. Energy used to generate electricity is excluded in order to avoid double-counting.

What's happening?

The main sources of energy in the Waikato region are electricity, coal, wood, natural gas, petrol, diesel and other oil products. Around 57,246 terajoules (TJ)1 of energy were used in the region during 2007. This energy was mainly used by:

  • industry (59% of total)
  • commercial and private transportation (30% of total)
  • households (11% of total).

    1. A joule is a unit of energy and heat, with one joule of power per second equaling one watt. A terajoule = 1 x 1012 joules. A gigajoule = 1 x 109 joules (1 billion joules).
