energieintensive

Energieintensive, or energy-intensive in English, is a term used to describe activities, sectors, or processes that require a large amount of energy relative to the output they produce. It is commonly applied in German-language policy and industry discussions as well as in international analyses.

Energy intensity is the key concept behind the term. It can be measured as energy consumption per unit of economic output, such as energy use per unit of GDP, or per unit of physical production, such as energy per ton of steel or cement. Lowering energy intensity is a frequent objective for improving efficiency, while total energy demand depends on both intensity and economic activity.

Industries typically characterized as enerjiintensiv include cement, steel, aluminum, chemicals, petrochemicals, glass, and fertilizers. Data centers and some pulp-and-paper operations may also be highly energy-intensive due to cooling, computation, or processing needs. These sectors are often the focus of energy policy because high energy costs affect competitiveness and energy security, and because decarbonization in these sectors can yield large emissions reductions.

Policy relevance varies by country. Governments may deploy energy pricing, subsidies, or exemptions to protect competitiveness, alongside efficiency standards, and incentives for switching to lower-carbon energy sources. Critics note that energy intensity alone does not capture total energy demand or emissions, since growth in output can offset gains from efficiency.
