Eco-electrical sector to lead efforts to cut CO2 emissions

In a recent White Paper, the eco-electrical sector* assessed potential CO2 emissions reduction that could be achieved through energy efficiency technology. The following forecasts are based on a European study as well as on field data.

Controlling energy demand, a key vector for decarbonizing the economy

The sector distinguishes between three kinds of actions to restrain building energy consumption: so-called “passive”, “performance” and “active” solutions (see our comprehensive overview on the webmag). Taken together, they could contribute to cutting CO2 emissions by 38% by 2050, according to the International Energy Agency: such solutions are potentially twice, respectively six times more efficient than the use of nuclear energy and renewable sources in the energy mix. “Active” solutions alone, if implemented on a large scale, could lower yearly emissions by around 7.5%.

Such achievements would mean a significant step towards France’s ambitious goals, as is stated in the conclusions of the February 2012 report by the French Centre for Strategic Analysis, i.e. that France will have to “make choices as to which measures it will decide to implement in order to save energy and decarbonise its productive capacities”.

Urgent need for improvement of housing energy efficiency

Such measures are all the more crucial if one considers the share of buildings in overall CO2 emissions. According to the report by the CGDD (sustainable development division of the French ecology ministry) on France’s 2011 energy balance, buildings were responsible for emitting 89 million tonnes of CO2 that year, i.e. 25.4% of national emissions. Players in the sector assume that a 25 to 30% emission cut is a sensible and achievable target. Besides, such estimates do not take the full emissions reduction potential into account since they do not include the savings induced by the widespread use of home automation. Smoothing energy consumption in such a way by reducing peak hours could avoid power plants relying on fossil fuels to be activated.
