In many respects the electric heater is an aberration ... Indeed, nearly 70% of the fuel energy burned in a power EDF (fossil or nuclear) is lost in the mists and distribution lines. Moreover, domestic heating contributes significantly to the phenomena of "peak" that require the rise of the most polluting power plants.
It is therefore more environmentally friendly and cost effective to burn the primary fuel (gas, oil, coal, wood ...) at the place of use rather than converting it into electricity. The use of a condensing boiler that recovers the heat in the smoke, allows scientists to achieve yields above 90% ...
French energy policy has greatly contributed to the development of electric home heating. The big mess of the 80s - when overproduction should sell nuclear reactors - has led to the widespread use of the most energy solutions such as electric heaters ...
An electric heating cheaper:
The latest survey by GfK Retail and Technology Office published June 21, 2010 shows a rise of technology radiators inertia (19%) at the expense convectors and other radiant panels.
For its part, the 2005 thermal regulation provides a safeguard on-joule heating effect in discouraging the use of coils for the benefit of radiant panels.
The improved coil (NF Performance Category C) is tolerated in small pieces and must be equipped with an electronically controlled high-quality 6 orders for the building into compliance with RT 2005.
A simplified formula can highlight the differentiated electricity consumption between different types of heat emitters wall:
Consumption Temperature = Setpoint + Temporal Variation (importance of heat waves - in particular, on the effective regulation of the thermostat (CA)) + spatial variations (temperature gradient created by the convection)
A power control increments or inertia that remove heat waves can reduce fuel consumption by 20%. Similarly, a low-temperature heating with high levels of radiation will produce an even heat from floor to ceiling (weak stratification) and reduce power consumption in the same proportions.
If these figures may seem surprising, however, they are audited by study "in vivo" conducted by radiator manufacturers and independent laboratories.
If your house is heated by coils of old poorly regulated, it is possible to reduce the consumption of at least 50% by installing an electric heater built into the frame (PRE, PRI, PRM ...) and more than 30 % with low temperature radiators inertia.
radiators inertia produce heat stable and homogeneous at low temperature, which limits the temporal and spatial variations in temperature. Furthermore, this technology transmits heat with a significant positive rate of radiation to thermal comfort the building is poorly insulated and control caloric needs of the human body.

new generation of offshore wind development in Japan. This offshore wind farm will produce three times more electricity than a system with conventional three-bladed. Read the article at Ourworld.unu.edu / en /
Wind power replaces the polluting
Saturday, December 4, 2010 when France bells in the snow, the French wind farm delivers instant power equivalent to three nuclear reactors. In windy conditions, the production of wind allows RTE to reduce the use of thermal-adjusting day / night, in the central priority in the most polluting fuel.
power of 2670 MW wind turbines is issued by a load factor of wind (5288 MW) slightly above 50%.
Antarctica: The Sea Shepherd identifies Japanese whaling poachers
On 31 December, 3000 km south-east of New Zealand, ships of the environmental organization the "shepherds of the sea" we spotted two harpoon vessels of the fleet Japan, the Yushin Maru 2 and 3. As in previous years, Sea Shepherd will attempt to resist until the end of March to the capture of thousands of whales in the whale sanctuary of the South Seas.
