How to Improve Energy Efficiency

In the face of the energy crisis last year, many countries developed policies for cutting energy consumption and reducing reliance on foreign fossil fuels. The war in Ukraine sent ripples throughout the world, waking many governments up to their reliance on foreign powers for their energy. Germany, for example, received 32% of their gas from Russia, as well as 34% of their crude oil and 53% of their coal [ref 1]. The loss of this source had a huge impact, they had no choice but to carve out a new approach to energy. Many countries turned to policies such as energy sobriety. In this blog we will explore what this policy entails, how it works, and how it might benefit your business.

In the realm of sustainable energy practices, terms like "energy efficiency" and "energy sobriety" are gaining prominence. While these phrases might seem interchangeable, they embody distinct approaches to managing our energy resources. This blog delves into the concept of energy sobriety, drawing inspiration from France's successful energy sobriety plan and relating it to the United Kingdom's energy reduction targets.

Defining Energy Sobriety vs Energy Efficiency

Energy efficiency and energy sobriety both aim to optimise energy usage, but they take different routes to achieve this goal. While these phrases might seem interchangeable, they embody distinct approaches to managing our energy resources. Energy efficiency involves using technology and practices to reduce consumption thanks to better performance of equipment, e.g. better insulation or less energy-intensive appliances. On the other hand, energy sobriety is a broader concept that emphasises a cultural and behavioral shift toward using less energy in the first place, e.g. lowering heating, disconnecting unused appliances. It encourages a mindset of moderation and conscious consumption. Both approaches have the same goal, but with different methodologies. In fact, they are two sides of the same coin, complementing each other to facilitate reduced consumption.

France's Energy Sobriety Plan: A Success Story

The President announced a new energy strategy in February 2022, based on four pillars: energy sobriety, energy efficiency, accelerating the development of renewable energies (EnR), and the revival of the French nuclear industry. They implemented their energy sobriety programme last winter, with a target of reducing energy consumption by 10% by the end of 2024. They wanted to mobilise the amount of energy whole country to reach their goal, through a combined approach of domestic, industrial, and state targets. Some examples of their policies were setting a maximum heating temperature of 19C in offices, incentivising government employees to work from home, and switching off lights in buildings when not in use [ref 2]. And they did it!

The Energy Transition minister Agnès Pannier-Runacher announced last month that they had exceeded their target a year ahead of schedule, reducing consumption by 12%. However, they aren’t stopping there: “We are going to stay on this objective. The challenge is to make the changes structural, so that we do not have to return to this objective and these habits that we establish take root… We must continue our efforts at sobriety,” said Pannier-Runacher [ref 3].

Their dedication to energy sobriety has produced real results, helping France on the way to their broader climate goals. This serves as a beacon of success and an inspiration to other countries – and to businesses.
