We're taking action to help spread the word about Gen Less

"Gen Less" is the Energy Efficiency & Conservation Authority's (EECA) initiative to help kiwis get more out of life by using less energy. Gen Less unites individuals, organisations, businesses & the government, to live & work in more climate-friendly ways.
Living Gen Less means you are choosing to take meaningful, ongoing action to reduce your greenhouse gas emissions from energy use.

How do we fit in with Gen Less?
