Energy Infrastructure Completed In 1989
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. 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 measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Interconnectors To And From The Nordic Grid
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Energy In Sweden
Energy in Sweden describes energy and electricity production, consumption and import in Sweden. Electricity sector in Sweden is the main article of electricity in Sweden. The Swedish climate bill of February 2017 aims to make Sweden carbon neutral by 2045. The Swedish target is to decline emission of climate gases 63% from 1990 to 2030 and international transportation excluding foreign flights 70%. By 2014 just over half of the country's total final energy consumption in electricity, heating and cooling and transport combined was provided by renewables, the highest share amongst the 28 EU member countries. About a third of Sweden's electricity is generated by nuclear power. In generating a year's worth of this energy, Swedes generate about 4 tonnes of emissions each. Since 2010, sustainability measures have reduced total emissions even as the population has increased. Swedish government climate and environment investment budget will be ca 1.3 billion euros in 4 years 2017 - 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
