In physics energy is a quantitative property, which must be passed to the 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 unit of energy in SI system is Joule, which energy transferred to the object in the work moving it to a distance of 1 meter from a force of 1 Newton. Common forms of energy include kinetic energy of a moving object, potential energy is stored in the location of objects in a force field, gravity, electric or magnetic, elastic energy stored by stretching of solids, the chemical energy is released when the fuel burns, radiant energy, portable light and heat energy due to the temperature of objects. Energy and mass are closely related. Because of the equivalence of mass and energy any object that has mass when stationary and writing paper-called rest mass also has an equivalent amount of energy whose form is called rest energy and any extra energy for any shape of the acquired object, the rest energy will increase the total mass of the objects in the same way as it increases its total energy. For example, after the heating of the object, its increase in energy can be measured as a small increase in mass, with a sufficiently sensitive scale. Living organisms need energy to stay alive, such as the energy people get from food. Human civilization requires energy to operate, which it receives from energy resources such as fossil fuels, nuclear fuels and renewable energy sources. Processes of the Earth, climate and ecosystems due to radiant energy the Earth receives from the sun and geothermal energy contained in the bowels of the earth.

Outline of energy

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


Brown energy

Brown energy may refer to: The term "brown Energy" was coined as energy produced from sources of pollution in contrast to the "green" energy from renewable, clean sources. This term is controversial because it may cause resentment, linking pollution / poor resources with color that people samoidentifikatsiya as. The term "grey energy" or "grey energy" used, including by the United Nations.


Drakoo wave energy converter

In the Drakoo WEC does not fall under any of the usual wave energy Converter classification: the principle of operation is based on twin-chamber oscillating water column system, is the transformation of waves in continuous flow of water that drives the hydro generator.


Driving factors

Energy monitoring and targeting, the driving factor is recurrent and measurable value which explains the differences in energy consumption. The concept of independent variable is sometimes used as a synonym. One of the most common factors is the weather, usually expressed as heating or cooling set. In energy-intensive processes of production indicators, as a rule, be used. For electric power circuit of outdoor lighting, the number of hours of darkness can be used. For a borehole pump, the amount of water will be used, and so on. What these examples have in common is that on a weekly basis, say, numerical values can be recorded for each factor and one would expect a specific flow of energy, to relate with them individually or in a multidimensional model. The correlation is perhaps more important than causation. The variation factors are sufficient to explain variation in consumption, it does not necessarily have to lead it, Although that will in most cases to deal with. Factors are different from static factors, such as building floor areas, which determine energy consumption, but rarely, if at all.
