Share of primary energy consumption from low-carbon sources (renewables + nuclear)

This statistic measures the share of a country’s total primary energy consumption that comes from low‑carbon sources—renewables (such as hydro, wind, solar, geothermal, modern bioenergy) plus nuclear power. It captures overall decarbonization of the energy system more broadly than electricity-only metrics, because it reflects energy used across power, transport, heating, and industry.

Values vary widely due to geography (hydro and geothermal potential), energy resources (fossil fuel dependence), policy choices (nuclear buildouts, renewable incentives), and economic structure. Countries with abundant hydropower or significant nuclear generation tend to have high low‑carbon shares, while fossil-fuel exporters and fast-growing economies often have lower shares despite renewable growth.
