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 consumption from electricity is an essential element of the U.S. economy since the beginning of the century. Coal power plants, a power source of electricity are available to deliver large quantities of low cost and reliable power supply. It has become more important than the supply of petroleum and natural gas, as the latter supply is decreasing over the time. In 1995, the burning of coal produces about 55% of the electricity produced in the U.S. We also know that coal reserves are expected to last for centuries at current use. (more…)

It is a reasonable and sensible action to tighten our belts and cut spending as living cost are climbing nowadays. We have to make small sacrifices if we want to survive the economic crisis which we don’t know when it will be ended.
For some folks cutting down expenses are difficult, but actually it is not going to be hard as we thought. Starting with small changes like re-arranging your home power consumption to be energy efficient would be a good start. If you manage to save some bill on household power consumption a bit often, the accumulation effect over a length period of time will be enormous. At the end it can help you in better shaping your financial situation. (more…)
