For economic and environmental reasons solar water heating systems are becoming a popular option for home water heating in New Zealand, and are also beginning to feature in commercial and industrial applications.
Making greater use of the sun's energy to heat water contributes towards reducing greenhouse gas emissions, helps lower New Zealand's dependency on non-renewable resources and reduces the rate of electricity demand growth.

A guide to energy efficient home lighting options.

Good lighting design and control can save up to 75% of industrial buildings lighting costs.

This technical guide outlines two key ways that industrial lighting operating costs can be reduced. It includes a range of no cost/low cost actions that can be undertaken as well as several actions for reducing energy use associated with industrial lighting which have a longer payback period.
