After lighting, personal computers (PC) and monitors have the highest energy use in office environments. Studies have shown that the power management of computers and monitors can significantly reduce the energy consumption per capita, saving hundreds or thousands of dollars per year in electricity costs. The energy consumption of computers and monitors will be needed by the amount of energy to work and how they are used is determined.
The installed base of approximately 71 million personal computers and 2.5 million workstations in 2000 consumed 17.4 and 1.8 TWh, respectively. (more…)
Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)
World energy use has increased steadily over the past several decades. Much of the growth in world energy consumption has been concentrated on the use of fossil fuels (oil, natural gas, and coal). This trend is expected to continue over the foreseeable future. Industrially mature nations will continue to rely on fossil fuels to meet their energy needs for all end uses, but the greatest rate of energy use is projected to occur in the emerging economies of the developing world.
