Efficiency, integration & electrification
Dubbed the “first fuel” in clean energy transitions, energy efficiency is the largest measure to curb energy demand in the IEA NZE by 2050 scenario. By reducing the amount of energy required to provide products and services, industry can reduce their climate footprint in a cost-effective manner.
Also, industry has a crucial opportunity to reduce its energy waste. For instance, the amount of heat wasted in the EU industry corresponds to the heat demand of 10 million single-family households. By pursuing sector coupling, industry can harness its excess heat using it onsite and ensure that any remaining heat is transported, stored or converted into valuable energy in the future integrated energy system.
When it comes to replacing fossil energy sources, electrification wherever possible is paramount, as electrified industrial processes are often far more energy efficient. Studies show that most industrial processes can be electrified either directly or indirectly. There is major potential to electrify heat in industries, particularly for temperatures up to 200°C. This is significant, as today, 47 percent of industrial energy is used for process heat, three quarters of which stems from fossil sources.
Currently, electricity accounts for only 23 percent of global industrial energy consumption. Thus, accelerating the industrial demand for electricity is not only crucial for energy efficiency but also for enabling the transition to renewables.
Decoupling consumption from growth
Historically, the emergence of industry has been considered inseparable from the rise of fossil fuels and increased energy consumption. But, since the 1990s, Denmark has managed to grow its industry and increase its GDP by 80 percent while lowering CO₂ emissions by 46 percent and overall energy consumption by 17 percent (2023). Though this is by no means a global trend, the Danish experience suggests the sustainable growth is possible.
