At least one major appliance maker plans to commercialize magnetic refrigeration for use in the home. The rationale for the change is that the technology uses no refrigerants or compressors and is said to be 20% more efficient than conventional techniques. It could also work well in HVAC.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/energy/magnetic-refrigeration-heats" target="_blank">read more</a></p> http://machinedesign.com/energy/magnetic-refrigeration-heats#comments Energy Sustainable Engineering Fri, 21 Mar 2014 14:23:00 +0000 35601 at http://machinedesign.com U.S. is using less electricity http://machinedesign.com/sustainable-engineering/us-using-less-electricity <div class="field-deck"> The U.S. EIA says the total U.S. electricity sales have declined in four of the past five years, and are on track to continue to decline in 2013. </div> <div class="node-body article-body"><p>The U.S. Energy Information Agency&#39;s latest <a href="http://www.eia.gov/todayinenergy/detail.cfm?id=14291" target="_blank" title="EIA energy report">Annual Energy Outlook</a> says electricity use in the U.S. has remained relatively flat over the past few years and probably will remain that was through 2015, after which the Agency expects growth to resume at historical rates of nearly 1%.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/sustainable-engineering/us-using-less-electricity" target="_blank">read more</a></p> http://machinedesign.com/sustainable-engineering/us-using-less-electricity#comments Sustainable Engineering Mon, 06 Jan 2014 22:08:00 +0000 33111 at http://machinedesign.com Renewable energy is up, nuclear is down http://machinedesign.com/technologies/renewable-energy-nuclear-down <div class="node-body article-body"><p> <img alt="Energy flow U.S. Lawrence Livermore National Laboratory" id="Each year, Lawrence Livermore National Laboratory releases energy flow charts that track the nation’s consumption of energy resources." src="/site-files/machinedesign.com/files/uploads/2013/08/2012newUSEnergy.png" style="width: 595px; height: 396px;" title="Each year, Lawrence Livermore National Laboratory releases energy flow charts that track the nation’s consumption of energy resources." /><br /> </p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/technologies/renewable-energy-nuclear-down" target="_blank">read more</a></p> http://machinedesign.com/technologies/renewable-energy-nuclear-down#comments Technologies Sustainable Engineering Thu, 22 Aug 2013 15:53:00 +0000 28811 at http://machinedesign.com <p> Each year, Lawrence Livermore National Laboratory releases energy flow charts that track the nation&rsquo;s consumption of energy resources.</p> Lawrence Livermore National Laboratory U.S. moves toward distributed wind power http://machinedesign.com/technologies/us-moves-toward-distributed-wind-power <div class="node-body article-body">This week, the U.S. Department of Energy released their 2012 Market Report on Wind Technologies in Distributed Applications.
