can you please simmarize these info. and break them into sevearl key points?

In 2015, 53% of the electricity worldwide was used in electric motor

systems (10 700 TWh) representing emissions of 5,5 Gton CO2eq [1], of which over 60% is used in industrial electric motor-driven systems, as shown in Fig. 1. Furthermore, the global industrial electricity consumption is growing, along with increasing GHG emissions, particularly in developing countries [2]. Motor systems also play a growing role in buildings, agriculture in infrastructure systems and in the transportation sector. Recognition of the important contribution of electric motors to the global electricity consumption has led to the introduction of MEPS in most industrialized countries. Mandatory minimum efficiency requirements have proven successful because a price premium is not easily accepted in industry even when the payback is short. Governments issue MEPS usually based on international standards. In the case of electric motors they are based on efficiency classes [3–5]. The efficiency classes for Direct-on-Line (DOL) motors are defined as IEcode in IEC 60034-30-1 [6], which is widely accepted as the global

standard, making efficiency classes comparable worldwide. The standard defines efficiency classes IE1 to IE4 (Fig. 2), where IE1 is the least efficient, IE4 is the highest efficient motor efficiency class. The new class IE5 is not yet defined in detail but is envisaged for potential

products in a future edition of the standard. It is the goal to reduce the

losses of IE5 motors by about 20% in relation to the IE4 class.

First introduced in the USA and Canada in 1997, MEPS for electric considerable delay when compared to other regions [8]. Likewise, regulation in other developing and emerging economies is still missing and poses a serious risk, as motor manufacturers may use these non regulated regions as a market for their lower efficiency products. Since motors have a very long lifetime, it is possible that these inefficient products may still be in use more than 20 years from the time they are sold [9–11]. On the contrary, early adoption of MEPS for electric motors will lock-in future electricity savings as the economy develops and improve the competitiveness of the economy by freeing capital from energy costs to other profitable investments. To help streamline the introduction of MEPS for electric motors in these economies, several initiatives have been undertaken which benefit from the experience gained in countries that have implemented MEPS for a longer time (e.g. UN-U4E, IEA-EMSA, CLASP, SEAD). In the context of these initiatives, reports and guidelines have been produced to guide policymakers on how to accelerate the adoption of energyefficient electric motors in their respective countries. The introduction of MEPS has pushed the market towards higher energy efficiency motors, helping to overcome identified barriers such as lack of information or split incentives, whilst simultaneously removing the worst products from the market [12]. However, electricity is the world's fastest-growing form of end-use energy consumption, especially among the emerging non-Organization for Economic Cooperation and Development (non-OECD) economies. Fig. 4 shows that motor system's electricity consumption is growing fast, and is projected to almost double by 2040, even with motors being targeted by energy efficiency promoting policies.

Answer 1

was used worldwide # Sol": • In 2015 ) 5.3% of Electricity by Electric Motors . Motors, • 60% of Electric motors lead to sos a ton CO2 motor driven system is growing in modern world $ developing countries leading to wreen House Cars emission . • The worldwide consumption has led goverment to issue MEPS ( Minimum Energy performance specification) based on international standard . MEPS i was first introduced in USA & Canada in 1997; • Many countries still lack in implementation of MEPS Thues, these countries can be the favourable market for lower efficiency Product :

Introduction of MEPS has shifted the market towards Energy Efficient system : in 'This MEPS initative removed the barriers of lack of information, split incentives while . Simultaneously removing the worst product from Market i
