some analyzes
-
- This classification dates from 2003 but these values have changed very little since, for example the construction of a wind farm has an extremely minimal influence on the discharges of a country, unless this country is very small, like Monaco for example. . See the 2 diagrams below for Germany between 1990 and 2005.
-
- Common ideas die hard: on CO2, Germany is far from being so clean compared to the “ecological” image it conveys
-
- Denmark, king of wind power, often presented as an EXAMPLE of sustainable development, is one of the countries which emits the most CO2 to produce its electricity, the fault "with no wind" (small oil or gas plants therefore very polluting). are started)
-
- The CO2 rate is obviously directly linked to the nature of the energy source to produce electricity, so if hydraulic and nuclear power are the cleanest in terms of CO2 (it is moreover the one and only ecological argument of the nuclear industry), coal is the dirtiest. And there are still a multitude of coal-fired power stations, particularly in England and Germany, the two major industrialized countries in this ranking with France. For more detail see the diagram below.
The DPE of the residence, in France, of which I am co-owner indicates for an energy index of 251,7 kWh EP/m2/year an emission of 58,9 kgeqco2/m3/year, i.e. 0,235 kg per kWh and no 0,084 Kg. Can we dispute the result 59,7 kg?
