cogeneration The capture ad use of waste heat; for example using waste heat from a power plant to heat adjacent factories and other buildings
conservation With respect to resources such as energy, refers to changing our patterns of use or simply getting by with less.In a pragmatic sense the term means adjusting our needs to minimize use of particular resource, such as energy.
energy An abstract concept referring to the ability or capacity to do work.
energy efficiency Refers to both 1st-law efficiency & 2nd-law efficiency.
first-law efficiency The ratio of actual amount of energy delivered where it is needed to the amount of energy supplied in order to meet that need; expressed as a percentage
first law of thermodynamics The principle that energy may not be created or destroyed but is always conserved
hard path Energy policy based on the emphasis of energy quantity generally produced from large centralized power plants
integrated energy management Use of a range of energy options that vary from region to region, including a mix of technology and sources of energy
micropower The production of electricity using smaller distributed systems rather than relying on large central power plants
second-law efficiency The ratio of the minimum available work needed to perform a particular task to the actual work used to perform that task. Reported as a percentage
second law of thermodynamics A fundamental principle of energy that states that energy always tends to go from a more usable form to a less usable form. When we say that energy is converted to a less useful form we mean that entropy of the system has increased.
soft path Energy policy that relies heavily on renewable energy resources as well as other sources that are diverse, flexible, and matched to the end-use needs
sustainable energy development A type of energy management that provides for reliable sources of energy while not causing environmental degradation and ensuring that future generations will have a fair share of Earth's resources.
work Force times the distance through which it acts. When work is done we say energy is expended.
