BRUSSELS - (Belgium EU) - 23/02/2011- 3B Tips - By Francis Rousseau - The WWF has recently published a report HERE nearly 250 pages (downloadable PDF HERE) has made public in early February before the Council of Europe and attracts the attention of leaders of EU member countries asking them to focus on energy efficiency s 'they want to progress on energy security. Tony Long, Director of WWF's European office, presented it by saying: "We can not continue to use fossil fuels without expecting to face serious increases in energy costs and devastating impacts on climate change climate. EU leaders must focus their efforts in implementing solutions already available to achieve the savings necessary to unlock the massive potential of renewable energy to 100%. The challenge is to deploy them in Europe and globally. "
The report, which deliberately avoids the overly optimistic assumptions about the benefits of renewable technologies present and future, place a scenario in which the planet's energy needs would be met almost entirely by renewable sources by 2050. The title of the report: "100% renewable energy by 2050" is very catchy in this direction but is But not as fully illustrated in the following text, which presents itself, in fact, a scenario in which a small portion of energy needs (5%) in the world world would continue in 2050 to be met by the use of fossil fuels .
The slower growth in energy demand (the drop in demand for connections) that shows some form of decay, therefore, is perhaps the most spectacular aspect of the WWF report, prepared by the firm international consulting Ecofys Energy. Indeed, despite an expected increase in population and increased travel, Ecofys scenario provides an opportunity decrease energy demand by 15% by 2050.
How would this be possible? Mainly by changing lifestyle and restructuring the sector of food production. The report calls on rich countries to reduce meat consumption by half (which is already on track!) And plans to reduce the distance food transport. Modes of transport itself would be restructured to improve efficiency through the electric drive widespread but also through individual actions such as the use of walking and cycling or bus and tram over short distances (it is already the case in many European cities but not enough) and the widespread use of rail rather than the aircraft on medium-haul.
From the viewpoint of WWF, build a sustainable future for all (with the wind and sun in the foreground) is about balance. Large traditional consumers of energy such as the United States are seeing their energy consumption will fall and further reduce power supply for 1.4 billion people who currently lack access to these energy sources. The report also looks at global warming and significantly reduced CO2 emissions by the scenario he proposes: "The CO2 emissions from the sector of energy supply would be cut by more than 80% by 2050, thereby reducing the temperature rise globally averaged less than two degrees Celsius (threshold identified as presenting some risk of catastrophic climate change) ".
