| Abstract from DBPedia | Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through energy efficiency, which has a number of advantages, including a reduction in greenhouse gas emissions, a smaller carbon footprint, and cost, water, and energy savings. Energy conservation is an essential factor in building design and construction. It has increased in importance since the 1970s, as 40% of energy use in the U.S. is in buildings. Recently, concern over the effects of climate change and global warming has emphasized the importance of energy conservation. Energy can only be transformed from one form to another, such as when heat energy is converted into vehicle motive power or when water flow's kinetic energy is converted into electricity in hydroelectric power. However, machines are required to transform energy from one form to another. The wear and friction of the components of this machine while running cause losses of very high amounts of energy and very high related costs. It is possible to minimize these losses by adopting green engineering practices to improve the life cycle of the components. Energy conservation day has been celebrated on December 14 every year since 1991. Energy can be conserved by reducing waste and losses, improving efficiency through technological upgrades, and improving operations and maintenance. Energy conservation can be accomplished by changing users' behaviors through user profiling or user activities, monitoring appliances, shifting load to off-peak hours, curtailing devices, and providing energy-saving recommendations. Observing appliance usage, establishing an energy usage profile, and revealing energy consumption patterns in circumstances where energy is used poorly, can pinpoint user habits and behaviors in energy consumption. Appliance energy profiling helps identify inefficient appliances with high energy consumption and energy load. Users can check appliance-wise energy usage before deciding on action for energy preservation, either curtailing these appliances or shifting to an off-peak hour. Seasonal variations also greatly influence energy load, as more air-conditioning is used in warmer seasons and heating in colder seasons. Achieving a balance between energy load and user comfort is complex yet essential for energy conservation. On a global level, energy use can also be reduced by stabilizing population growth. On a larger scale, a few factors affect energy consumption trends, including political issues and countries, population growth or decline, technological developments, economic growth, and environmental concerns. On a smaller scale, the following factors affect energy conservation capability, including seasonal variations and accuracy, precision, and recall of appliances. Other key attributes that affect energy conservation include user activity detection, user energy usage profiling, user comfort, appliance energy usage profiling, appliance weights, off-peak hour scheduling, energy scenario scheduling, seasonal variations, and energy-saving recommendations. Seasonal variations significantly affect energy consumption, as energy demand for air conditioning increases in the summer. Seasonal energy consumption differs and must be considered when developing energy conservation techniques.省エネルギー（しょうエネルギー、英語: energy conservation）とは、同じ社会的・経済的効果をより少ないエネルギーで得られるようにすることである。省略して省エネ（しょうエネ）とも言われる。 (Source: http://dbpedia.org/resource/Energy_conservation) |
