Resource rent generated from renewable energy sources in New Zealand

Resource rents: revenue generated from a resource less all costs incurred in its extraction; for all assets except fish, include a return to land.
Asset value: market price of an asset if it was sold.
Total electricity generation: electricity generated from all sources in New Zealand.
Geothermal resources: derived from groundwater heated naturally within the earth's crust.
Wind: wind energy is a process of exploiting the kinetic energy of wind. Wind turbines convert this kinetic energy into mechanical power, which can be used to generate electricity.
Wood: trees and plants use solar energy to convert water, carbon dioxide, and nitrogen into hydrocarbons. This energy is stored in plants and can be replaced by burning plant biomass. Burning plants produces heat, which can be used to create electricity.
Biogas: biogas (mostly methane) is generated by the anaerobic digestion of organic matter by bacteria. Sufficient quantities of methane can be generated from landfills and wastewater treatment sites to provide a valuable source of energy. Biogas can be burnt to produce heat, or can be used in specialised combustion engines to create electrical energy.
Solar: solar photovoltaic systems directly convert solar energy into electricity. Light energy hits the solar panels and excites the electrons in the atoms of semi-conducting material the movement of these electrons results in an electric current.

Estimates for the asset value of non-renewable forms of electricity generation (oil, coal, and gas) are not presented in this data.

Environmental-economic accounts show how our environment contributes to our economy, the impacts of economic activity on our environment, and how we respond to environmental issues.
This dataset presents the estimated asset values of water, geothermal (steam), wind, sun, wood, and biogas in New Zealand that are used to generate electricity. A renewable resource, or renewable, is a resource that after being used, can return to previous stock levels by natural processes of growth.

Environmental accounting is the measurement of environmental assets in monetary terms. It focuses on the value of an environmental resource and the changes in that value over time. One aim of environmental-asset accounting is to assess whether patterns of economic activity are depleting or degrading our resources. Information from an environmental-asset account can be used to manage the resource. The valuation of a natural resource, such as water and managed fisheries, can be combined with valuations of other physical or financial assets (eg. machinery or equity and investment fund shares) to provide estimates of national wealth.
