A caloric deficit (also known as calorie deficit, in British English calorific deficit) is any shortage in the number of calories consumed relative to the number of calories needed for maintenance of current body weight (energy homeostasis). A deficit can be created by decreasing calories consumed by lower food intake, such as by swapping high ...
There is an increasing focus on energy poverty in the European Union, where in 2013 its European Economic and Social Committee formed an official opinion on the matter recommending Europe focus on energy poverty indicators, analysis of energy poverty, considering an energy solidarity fund, analyzing member states' energy policy in economic ...
Household energy insecurity is a broad framework that includes a household's inability to afford energy costs as one of several factors in a household's ability to meet energy needs. Household energy insecurity is influenced by both internal and external factors such as energy cost, household income, housing conditions, and personal behavior. [ 1 ]
Energy descent is a process whereby a society either voluntarily or involuntarily reduces its total energy consumption. Energy descent can be understood in relation to peak oil, in which case there is a theoretical post-peak-oil transitional phase characterized by a descending use of energy. The peak oil energy descent model has focused mainly ...
According to the FAO, the average minimum daily energy requirement is approximately 8,400 kilojoules (2,000 kcal) per adult and 4,200 kilojoules (1,000 kcal) a child. [3] This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake, [ 4 ] with the exception of the ...
Measurable energy conservation and efficiency gains in the 1980s led to the 1987 Energy Security Report to the President (DOE, 1987) that "the United States uses about 29 quads less energy in a year today than it would have if our economic growth since 1972 had been accompanied by the less- efficient trends in energy use we were following at ...
The deployment of energy efficiency technologies is highly restricted by factors such as geography, infrastructure and human resources. Behavioral barriers are problems that characterize the end-user's decision-marking relating to energy consumption. Four examples are discussed below. Attitudes toward energy efficiency.
Energy consumption in the body is a product of the basal metabolic rate and the physical activity level. The physical activity level are defined for a non- pregnant , non- lactating adult as that person's total energy expenditure (TEE) in a 24-hour period, divided by his or her basal metabolic rate (BMR): [ 2 ]
