Energy, Work and power of the body All body activities including thinking, doing work, or keeping the body temp. constant involve energy changes, for example under resting(Basal)conditions the skeletal muscles and the heart using 25% of the body's energy ,another 19%is being used by the brain,10%is being used by the kidneys, and 27% is being used by the liver and the spleen. A small percent of about 5% of food energy being excreted in feces and urine. Extra food energy will be stored mainly as fat

countries including the United States, United Kingdom and France. USCA for example saw state appropriations reduce from $11.1M in 2008 to $6.1M in 2011. Rising costs of energy in part due to under-capacity to store during off-peak seasons and infrastructure overhaul project investments compound budgetary decision making. Reducing energy consumption requirements partially can alleviate the funding shortfall. Environmentally friendly solutions that reduce dependence on, or usage of fossil fuels, can

environmental. Its origin back to 1992, when the U.S. Environmental Protection Agency launched Energy Star,a voluntary labeling program which is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies. This resulted in the widespread adoption of sleep mode among consumer electronics. The term "green computing" was probably coined shortly after the Energy Star program began. I will slightly demonstrate its impact on our budget and environment
