High efficiency is particularly relevant in systems that can operate from batteries. Inefficiency may require weighing the cost either of the wasted energy, or of the required power supply, against the cost of attaining greater efficiency. Efficiency can usually be improved by choosing different components or by redesigning the system. Inefficiency probably produces extra heat within the system, which must be removed if it is to remain within its operating temperature range. In a clim

Investments and a commitment towards energy efficiency abound, yet a number of barriers inhibits the deployment of energy efficiency solutions. Lack of awareness of saving potential, a focus on devices rather than systems which leads to a lower return on investment and a preference for lower cost rather than life-cycle gains are
A major share of electric energy consumption is attributable to electric motor systems (EMS) [4, 5] thanks to their widespread diffusion in a number of industrial applications and purposes. Despite the existence of minimum efficiency mandatory standards in most of the Countries for new motors, about 70% of the total energy
Abstract. Compressed air is the most important input for the production processes of many businesses today. Nevertheless, generally, compressed air systems are highly inefficient, resulting in a big amount of wasted energy and cost. Compressed air is very expensive as only 10–20% of the electric energy input reaches the point of end-use.
This paper focuses on the energy issues in relation to the power quality problems in the power distribution systems of buildings and describes the proposed standards and requirements of power quality as set out in the Electrical Energy Code. 1. Introduction
Mitigating climate change and achieving stabilization of greenhouse gas atmospheric concentrations — the objective of the United Nations Framework Convention on Climate Change (UNFCCC) — will require deep reductions in global Energy-related Carbon Dioxide (CO2) emissions. G-8 leaders called for a 50% reduction in greenhouse gas (GHG)
Abstract. With the 2009/28/EC Directive, the European Union has to guarantee three objectives by 2020: 20% reduction in greenhouse gases emissions, 20% share of renewable energy and 20% improvement of energy efficiency. New technologies and policies applied to power systems can positively influence the overall energy

Energy efficiency is providing the same or better service using less energy. Energy services are all the benefits we derive from energy use, such as illumination, thermal comfort, cooking, transport of people and freight, and many industrial and agricultural functions. Increasing end-use energy efficiency is often the least expensive and one of

In recent years, many studies identified large energy efficiency potentials in electric motors and motor systems with many saving options showing very short payback times and high cost-effectiveness. Furthermore, almost all electricity in India is generated by rotating electrical generators, and approximately half of that generated is
To deliver the most efficient, future-proof electrical systems, the designer needs to become familiar with the most current, relevant standards and guidelines within their region, and their relationships to each other. Doing so will help a building achieve best-in-class energy efficiency and green building certification.
