27 February 2013 — Energy efficiency is the biggest, cheapest, fastest way to cut greenhouse gas emissions and cut energy costs but time is running out for Australia to heed the advice, International Energy Agency energy efficiency head Robert Tromop says. Mr Tromop will be one of 300 experts, business people and policy-makers in Sydney this week at The Australian Alliance to Save Energy Summer Study to discuss solutions for a lower cost, more efficient Australia. “Our research shows that saving energy can buy time for the climate, delaying the complete ‘lock-in’ of the allowable emissions of carbon dioxide under a 2ºC trajectory– currently set to happen in for 2017 – by an extra five years,” he said. “Even though it is cost effective for the end users, two-thirds of this potential will remain untapped without specific, new action by governments.”
