If anyone would ask a child if they would allow themselves to have another scoop if their favorite ice cream flavor, they will instantly shout and yell “more please!” But even if they have shouted their hearts out, they will find out that too much ice cream can cause them stomach aches later on. This goes the same with the eve increasing energy-efficiency levels.
Over the last 30 years of recent technology advancements, the motor industry has shown the ever increasing total efficiency of the typical 5 horse power motor from 85% wooping to total of 90%. However, the regulators in these machines together with some selected energy advocates are continuing to show or propose higher levels. There’s a requirement of certain changes concerning one area but some companies tend to forget how it should interact with the other aspect in the overall system. Because forgetting this important aspect can lead to reduced energy savings that comes with unintentional or unintended consequences. Like adding a favorite scoop of ice cream on top of the ice cream you just ate earlier, it is extremely unreasonable. To continue raising some of the efficiency levels on certain individual components does not necessarily mean that it should give greater savings on these energy products or it doesn’t mean having better products.
While these energy motors can be manually tested and have some measurements be made, this does not mean that these tests would mean a great reduction in wasted energy. In addition and result of this observation the focus of NEMA organization has changed from doing a minimal increase in energy efficiency to focusing on a more important matter – total energy savings derived from this observation.
The another possible conflict that may arrive at hurdling in developing an overall energy system is in terms of the possible the estimation and formulation efficiency standards to come up with the amount of energy used. This energy that is being used is intended to the usage of one certain product rather than having a single testing point for the product. In IEC 61800-9-2 Adjustable speed electrical power drive systems—Part 9-2: the Ecodesign for the energy power drive systems, power electronics and energy motor starters – the gage for the energy efficiency indicators should showcase some system drives for the several motor starters. The need for the testing of energy efficiency is shown in this regulation. Consequently, the additional steps for this is the shifting of the existing assumption and connotation that having more energy regulation is a better approach of the overall system. Compared to the idea that energy saving management achieved by having a better and more efficient management happening in the system level and increased compliance to the existing regulations, the current mantra should be shifted to this.
In conclusion, energy companies should look at the overall savings incurred by having a more reliable system that computes the overall energy saved rather than looking at how much a device can efficiently save on energy.
