Energy and Energy Efficiency

saving means for saving oil gas and solid fuels.
One of the most common ways to save energy is the replacement of incandescent light bulbs with fluorescent bulbs that emit light energy several times higher than the same amount of energy consumed raw. Also in the heating of buildings are more or less simple methods to save energy, such as the use of thermostatic valves, the use of programmable thermostats and other more challenging, such as replacing old boilers with condensing boilers. Energy savings you can have a level of electricity production using systems that improve the performance of various processes, which consist of technology made in order to obtain electricity and heat, or energy recovery are carried out forms a closed loop.

Or uses the energy lost in the motion of humans or cars, com 'has already been made in Netherlands, for example with pressure-sensitive floors, placed in the scale of the busiest subway in the world, producing electricity.
appropriate measures to avoid the waste of energy to produce heat:
use electric heaters, air conditioners and heat pumps with water cooled heat exchanger.
in air conditioning systems, use groups of absorption running hot water, otherwise obtained with solar panels, instead of electric compressors;
launch production of washing machines with two entrances both hot and cold water, the current ones have a single entrance, used for cold water, which is heated electrically inside the appliance if necessary.
