                Household Energy Affordability Executive summaryExecutive summary

                Household energy affordability continues to be a key priority for governments as energy bills remain elevated Household energy bills globally have come down from the peaks seen during the global energy crisis in 2022, but on average they were still around 4% higher in real terms in 2024 than they were in 2019. Household energy bills soared in many parts of the world as a result of the Covid-19 pandemic and Russia’s full-scale invasion of Ukraine in 2022, which introduced a period of extreme volatility and a sharp run-up in prices.
