Energy efficiency is a key to combat climate change
By Janice Blondeau
As the world prepares for , the 2015 Paris Climate Conference, the International Energy Agency () estimates in its
that energy efficiency is the most effective tool to reduce greenhouse gas emissions with an aim to limit global warming to 2 degrees Celsius or below. IEC work is behind the scenes helping to increase energy efficiency and reduce the amount of energy that is lost in everyday consumption.
IE codes help regulators to determine the minimum efficiency levels for electric motor energy performance in their regulations
The IEA has found in 2014 that energy efficiency improvements in IEA countries over the last 25 years have saved households and businesses USD 550 billion. In addition, energy efficiency improvements since 1990 have avoided a cumulative 10,2 billion tonnes of CO2 emissions in IEA countries.Redesign the energy chainIn order to increase energy efficiency there is also a need to look at how we generate and consume energy, to redesign systems on a global scale, rather than individual products in specific countries or regions. Right now a lot of raw energy is wasted. The smarter use of electric energy, what the IEC calls &smart electrification&, can help reduce emissions. For this, globally accepted metrics and technological expertise such as those developed by the IEC need to be applied to achieve optimal outcomes and eliminate market confusion.Industrial energy saving motorsReducing energy waste in electric motors is a concrete example of IEC work in action. Industry, especially electric motor systems are estimated to account for more than 40% of global electricity use (1). Two thirds of all electricity used by industry drives electric motor systems. They convert electrical energy to mechanical energy, rotate pumps, drive compressors, move materials and run fans, blowers, drills or mixers. &Motors are huge consumers of electricity, even small improvements can lead to large energy savings.IE codes drive efficiencyThe IEC has put in place energy efficiency classes for electric motors. These allow manufacturers and regulators to easily identify how efficient an individual motor performs. Each level of efficiency has its own IE code. Their performance criteria are summarized in IEC International Standard . The IEC classification system includes four levels of motor efficiency:
IE1 Standard efficiency
IE2 High efficiency
IE3 Premium efficiency
IE4 Super premium efficiency
Widespread adoptionThe IE codes help regulators to clearly define minimum efficiency levels for electric motor energy performance in their regulations. The IEC
classification system has stimulated competition among motor manufacturers and generated massive technology improvements. While IEC International Standards are voluntary, the European Union (EU) and numerous other countries have adopted the IEC classification system.In the EU, Directive 640/2009, became effective as of January 2015 for motors with a rated output from 7.5-375 kW and from 2017 for motors with a rated output from 0,75-375 kW. This measure, which is generally referred to as EU Minimum Energy Performance Standard (MEPS), is expected to result in energy efficiency improvements of 20% to 30%. An internationally harmonized efficiency Standard IEC 60034-30, was developed under German leadership within the IEC.More information about IEC IE energy efficiency classes for electric motors .,

　　【环球网报道 记者 王欢】日本《读卖新闻》12月1日报道称，当地时间11月30日下午，出席联合国气候变化缔约国第21次会议(COP21)的中国国家主席习近平，在法国与日本首相安倍晋三在COP21会场进行了简短站立交谈。
　　报道称，习主席表示，正确处理中日相互之间的微妙问题，对于两国关系至关重要。围绕2014年11月和2015年4月举行的中日首脑会谈，习主席表示，中日拥有共同的利益，深化良好的氛围非常重要。对此，安倍表示，希望进一步推进两国间人文交流领域的合作。
　　据安倍随行人士透露，此次会谈大约持续4分钟，双方为站立交谈。据称，由于习主席和安倍在午餐会的坐席距离较近，安倍主动向习主席打招呼，双方进行握手。
　　另据日本《产经新闻》报道，正在法国访问的中国国家主席习近平与安倍11月30日下午进行了站立交谈，双方就继续深化中日战略互惠关系达成一致。安倍在交谈中提及了11月在首尔举行的中日韩三国领导人会谈，称“此前能够与李克强总理良好地交换意见，这非常好”。
　　报道称，习主席还表示，能够看到中日两国之间的关系正在变化的征兆。
