The sun is probably the most important source of renewable energy available today. Traditionally, the sun has provided energy for practically all living creatures on earth, through the process of photosynthesis, in which plants absorb solar radiation and convert it into stored energy for growth and development.
You won't believe these 10 facts about people. Energy homeostasis describes the ability of all living things to sustain the stability of internal functions. Most living things require certain internal conditions to survive.
The Energy Factor, or EF, is a performance metric that determines the efficiency of appliances such as clothes washers, dishwashers and hot water heaters. Energy Factor is an older metric that preceded the Modified Energy Factor (MEF), which is in use as of 2013. These figures are calculated for washing machine brands in an effort to determine whether the model qualifies for an Energy Star rating.
