The efforts of engineers to improve performance led the French physicist and engineer military Nicolas L. gas is supplied by that has been at the forefront of the energy supply market S. Carnota to the formulation of the laws of thermodynamics in 1824. These laws are based on the experience but with significant wealth, and are essential to increase the performance of the use we make every day more scarce energy reserves to generate electricity cogeneration energy performance in the generation of electricity depends to last analysis of the laws of thermodynamics. By increasing the temperature of entry into the gas turbines through the introduction of new materials and design techniques, the performance of the latest turbines has increased gas by 42 . If the hot gas output is used to electricity raise steam to power a steam turbine, resulting in a so-called combined cycle, with a return of the widespread conversion of heat into electricity for around 60 . Combined cycle plants that run on gas are rapidly replacing that of coal and oil in the world. having moved to Energy An incentive for construction is the least environmental impact and the reduction of carbon dioxide emissions involved. An even more effective way of using fossil fuel energy is the primary construction of cogeneration systems or Combined Heat and Power (ECC). In this case, the heat output of the gas turbine or steam engines and even used to fuel diesel generators to supply electricity and steam heat and other elements energy costs of the factory. These systems have an overall efficiency in energy use over 80 (this system is illustrated in the diagram). There are many circumstances in which business systems are ideal for ECC balance electricity / heat necessary, and represents a breakthrough in installation costs and saving energy.
TRANSPORT The transport sector is the most polluting of all, causing more carbon dioxide to the generation of electricity or the destruction of forests. There are now in the world and 500 million vehicles in Western Europe is estimated that their number will double in 2020. In developing countries, growth will be even faster. Although the performance of the engines of vehicles has been greatly improved through the ignition control and the use of diesel engines, the trend remains vehicles with performance far superior to those that allow the roads. Congestion and pollution are stimulating the emergence of movements for electric traction and the extension of public transport. ENERGY POLICY deregulation and privatization of the energy supply system household with the introduction of energy policy in the hands of the market, encourage producers to increase their profits by selling more and more amount of energy and reducing their willingness to preserving it. The only limitations are the laws on pollution. As for demand, users seem reluctant to install energy saving systems, despite the savings they supondria for three or four years. An example is the energy-efficient lamps. There is no doubt that we should make more efficient use of energy resources in the world in the future, if you want to energy meet growing demand for energy of a rapidly growing population and industrialization. The pressure on the limited resources of fuel and increasing levels of the population requires an urgent response.
fossil fuels. The discovery that the energy and not create or should discourage inventors machines pedestrian movement consumode processes in refineries and others. In contrast, with regard to the demand side (energy used for heating of buildings, electrical appliances, lighting …), has been neglected in the part of the supply, with a wide margin for improvement. In Western Europe 40 of final energy consumption is devoted to domestic sector, 25 to 30 industry and transport.
Sector domestic and commercial buildings more or less half the energy consumed in Western Europe goes to buildings. With modern technology to save energy consumption can be reduced to 20 in five years. It should encourage the construction of designs with good insulation, efficient use of energy in the lighting, the installation of energy control systems and equipment for modern and efficient heating, air conditioning, refrigeration and cooking. The labels on the devices with information on the effectiveness of its operation to help choose the most suitable system.
