Grenoble’s energy master plan : less waste, more renewable

The real way to move forward in the energy transition is to consume less energy to heat, move, manufacture … The need is also to gradually replace fossil fuels such as gas, gasoline and fuel oil by renewable energies! To achieve this, the Grenoble metropolitan area has a demanding roadmap by 2030 : reduce all energy consumption by 22%, boost renewable and recovery energies by 35% and reduce fossil energies by 30%.

Between climate change and an ever-increasing cost of energy, everything is pushing us today to understand our energy consumption differently. The challenge is great, but there are many resources in the Grenoble area. Grenoble-Alpes Métropole is positioning itself as a pioneer territory in this field.

Ambitious objectives

Since 2004, the city was the first in France to adopt an Air Energy Climate Plan, a kind of first roadmap for the energy transition. Armed now with new levers of action thanks to the status of Metropolis, it sets up a strategy (energy master plan) and actions to make the territory an example in the field, with concrete objectives by 2030:

• Reduce all energy consumption by 22%
• Boost renewable and recovery energies by 35%
• Reduce fossil energies by 30%
• Greater leeway for the Metropolis in terms of energy

These objectives are accompanied by a roadmap for achieving these results. Some concrete examples of actions to be carried out by 2030:

• 4 new biomass heat networks
• Renovations of over 40.000 homes and detached houses
• Build a new biogas unit for food waste
• Pass the metropolis waste collection buses and trucks to biogas

A pioneer process in France

This is the result of two years of collaborative work involving energy, research and innovation stakholders as well as partner associations and citizen users. These exchanges have nourished, step by step, the scenarios of evolution of the energy on the territory:

• An inventory has been drawn up on energy consumption, production and networks. Assumptions were made on the evolution of the activity of the territory, the number of housing, employment …
• The modeling of the data then made it possible to calculate the economic and environmental relevance of a set of actions: insulation of buildings, change of boilers, etc.
• The selected actions consitute the scenario presented in the Energy Master Plan.
