A comprehensive modelling exercise into the country's energy future shows the economy is set for a major transformation by mid-century, with less reliance on primary produce and more on services. The BusinessNZ Energy Council, along with partners in business, academia and government have updated their detailed energy modelling exercise and posits two scenarios by mid-century: one where the global policy response to climate has been at the lower end and New Zealand's response slower; and the second, where the global and domestic response has been stronger and faster. Kathryn talks to John Carnegie, Executive Director of Business NZ Energy Council about the results.
