energiamix

Energiamix, or energy mix, refers to the relative shares of different energy sources used to meet a region’s or economy’s total energy demand. It is typically expressed in terms of the shares of primary energy consumption or electricity generation from categories such as fossil fuels (coal, oil, natural gas), nuclear power, and renewable sources (hydropower, wind, solar, bioenergy, geothermal). The energy mix can be analyzed for the overall energy system, or broken down by sector (electricity, heating, transportation).

In practice, the energy mix reflects a combination of resource availability, technology, policy objectives, market prices, and infrastructure. It varies widely by country and over time. For electricity, the mix is influenced by capacity additions, plant age, dispatch rules, storage options, and grid interconnections. In heat and transport, the mix depends on fuel choices, building standards, vehicle fleets, and incentives for efficiency and electrification.

Measuring the energy mix helps assess energy security, economic resilience, affordability, and environmental impact, including carbon intensity. It is a common planning and reporting metric for governments, regulators, and utilities. As policies aim to reduce greenhouse gas emissions and increase renewable deployment, countries often shift their energiamix toward lower-emission sources and greater electrification, while balancing reliability and cost.
