Efficient energy use , sometimes simply called energy efficiency , is the goal to reduce the amount of energy required to provide products and services and can also reduce effects of air pollution. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs , fluorescent lighting , or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process  or by application of commonly accepted methods to reduce energy losses. There are many motivations to improve energy efficiency.
Energy efficiency simply means using less energy to perform the same task — that is, eliminating energy waste. Energy efficiency brings a variety of benefits: reducing greenhouse gas emissions, reducing demand for energy imports, and lowering our costs on a household and economy-wide level. While renewable energy technologies also help accomplish these objectives, improving energy efficiency is the cheapest — and often the most immediate — way to reduce the use of fossil fuels. There are enormous opportunities for efficiency improvements in every sector of the economy, whether it is buildings, transportation, industry, or energy generation. Building designers are looking to optimize building efficiency and then incorporate renewable energy technologies , leading to the creation of zero-energy buildings.
Energy conservation is the decision and practice of using less energy. Energy conservation and efficiency may be related, but they have distinct definitions in the energy world. Energy conservation involves using less energy by adjusting your behaviors and habits. Energy efficiency, on the other hand, involves using technology that requires less energy to perform the same function. So why is it important to conserve energy? While energy efficiency might cost you money up front before potentially saving you money down the road, energy conservation is something you can put into practice immediately, either at very little or no cost to you. Here are 10 energy conservation ideas you can get started with today.
High Performance Computing HPC is a key technology for modern researchers enabling scientific advances through simulation where experiments are either technically impossible or financially not feasible to conduct and theory is not applicable. This paper aims to give an overview of the current state of the art and future techniques to reduce the overall power consumption of HPC systems and sites. We believe that a holistic approach for monitoring and operation at all levels of a supercomputing site is necessary. Thus, we do not only concentrate on the possibility of improving the energy efficiency of the compute hardware itself, but also of site infrastructure components for power distribution and cooling. Since most of the energy consumed by supercomputers is converted into heat, we also outline possible technologies to re-use waste heat in order to increase the Power Usage Effectiveness PUE of the entire supercomputing site.

Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently using less energy for a constant service or by reducing the amount of service used for example, by driving less. Energy conservation is a part of the concept of Eco-sufficiency. Energy conservation measures ECMs in buildings reduce the need for energy services and can result in increased environmental quality, national security , personal financial security and higher savings. Energy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades and improved operation and maintenance. On a global level energy use can also be reduced by the stabilization of population growth. Energy can only be transformed from one form to other, such as heat energy to motive power in cars, or kinetic energy of water flow to electricity in hydroelectric power plants.

Efficient energy use
Energy efficiency can enhance human health by reducing greenhouse gas emissions, improving outdoor air quality and decreasing acid rain. The energy needed to run commercial and industrial buildings in the United States produces 19 percent of U. The health care sector is in need of cost-effective solutions to address the rising cost of energy and the health implications of energy use. Once a facility has developed an energy baseline by tracking and measuring its energy use , it can begin to zero in on areas of inefficiency and review potential energy reduction strategies with an eye for what will work given the financial resources of the organization.
Energy Management Principles: Applications, Benefits, Savings, Second Edition is a comprehensive guide to the fundamental principles and systematic processes of maintaining and improving energy efficiency and reducing waste. Fully revised and updated with analysis of world energy utilization, incentives and utility rates, and new content highlighting how energy efficiency can be achieved through 1 of 16 outlined principles and programs, the book presents cost effective analysis, case studies, global examples, and guidance on building and site auditing.
