Historically, our economy focused on extracting raw materials (gold, wood, cow and so on). Willing to transform these raw materials for some end-use purposes (luxury, transport, feed and so on), firms started selling goods as more or less differentiated products (jewels, boats, steak and so on). Then, firms move to services (fit jewels and clothes, offer mobility, serve hamburger in your favourite fast-food restaurant and so on). The natural evolution is to provide experience to end consumers (feeling pretty, enjoying a nice trip in a train where you can dance like in a club, enjoying tasty food in a very practical environment).
One of the key variables in an Energy Efficiency project, with the discount rate, is energy prices and their evolution through the time. Quite profitable Energy Efficiency projects have usually a few-year payback time. You may want to choose a not too bad ballpark value in order to make your project secured in the long run. Let’s not read in a crystal ball, but try to understand the main determinants, which influence energy prices.
Buildings in France, as worldwide, account for a high 40% of global energy consumption. Large and attractive opportunities exist to reduce buildings’ energy use at lower costs and higher returns than other sectors. These reductions are fundamental to support achieving the European Union’s 20-20-20 for 2020 policy and the International Energy Agency’s target of a 77% reduction in the planet’s carbon footprint against the 2050 baseline to reach stabilized CO2 levels called for by the Intergovernmental Panel on Climate Change.
