How to cut energy waste in China, India, Brazil said crucial to forestalling climate change

Without significant gains from energy efficiency efforts, China, India and Brazil within a single human generation (by 2030) will more than double their energy use and greenhouse gas emissions, resulting in major impacts on global energy markets and climate. However, experts estimate that cost-effective retrofits could reduce those countries' energy use today by at least 25 percent and advanced technologies could reduce their energy use growth projected through 2030 by at least 10 percent (and reduce projected CO2 emission growth by 16 percent).
