The world’s energy demand can be cut by 25 percent by 2030, according to a study from the Renewable Energy Agency and the Copenhagen Centre on Energy Efficiency.
Results will vary across the countries studied, which were China, Denmark, France, Germany, India, Italy, the United Kingdom and the United States, according to the story on the report at Environmental Xprt. The aim of the study was to explore strategies for fulfilling levels set forth in The United Nations’ Sustainable Energy for All Initiative.
The report provides examples of approaches that can increase efficiency. For instance, it notes that gas condensing boilers are considerably more efficient than traditional technologies and that solar water heaters are 100 percent efficient – which is 15 percent more efficient than coal-fired boilers. Using scrap steel to manufacture new steel will save “huge amounts” of energy compared to using iron ore as the raw ingredient.
Other projects are underway. Cleveland.com reports that Cuyahoga County and Case Western Reserve University are involved in several research projects. One will be on sustainability energy. The researchers will assess energy use at buildings owned by the county and the Cuyahoga Metropolitan Housing Authority and develop recommendations and an on-line tool to provide information on environmental goals and information on renewable energy generation costs and other topics.
