Energy

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an objects position in a force field gravitational, electr ...

Outline of energy

The following outline is provided as an overview of and topical guide to energy: Energy – in physics, this is an indirectly observed quantity often understood as the ability of a physical system to do work on other physical systems. Since work is defined as a force acting through a distance a length of space, energy is always equivalent to the ability to exert force a pull or a push against an object that is moving along a definite path of certain length.

                                               

Brown energy

Brown energy may refer to: The term "brown energy" has been coined as energy produced from polluting sources as a contrast to green energy from renewable, non-polluting sources. This term is controversial, as it can cause offense by associating polluting/bad resources with a color that people self-identify as. The term "grey energy" or "gray energy" has been used instead, including by the United Nations.

                                               

Drakoo wave energy converter

The Drakoo WEC does not fall under any of the usual wave energy converter classifications: its working principle, based on a twin-chamber oscillating water column system, is to transform waves into a continuous water flow which drives a hydro turbine generator.

                                               

Driving factors

In energy monitoring and targeting, a driving factor is something recurrent and measurable whose variation explains variation in energy consumption. The term independent variable is sometimes used as a synonym. One of the most common driving factors is the weather, expressed usually as heating or cooling degree days. In energy-intensive processes, production throughputs would usually be used. For electrical circuits feeding outdoor lighting, the number of hours of darkness can be employed. For a borehole pump, the quantity of water delivered would be used; and so on. What these examples al ...
