Economic growth
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores economic growth. Why is energy efficiency important for economic growth? Energy efficiency allows countries to generate more economic activity using the same amount of energy. It is also linked to increased labour productivity and other economic benefits. Key facts Compared with 2000, today’s global economy produces 36% more GDP per unit of energy. Energy efficiency progress over the last 20 years means that close to an extra USD 50 trillion can today be produced using the same amount of energy. This energy efficiency bonus is equivalent to…

Gas Market Lessons from the 2022-2023 Energy Crisis
The 2022-2023 energy crisis tested the resilience of the global gas and LNG markets with the most severe gas supply shock in history. During the crisis, natural gas-importing markets around the world felt the pressures of record-high gas prices, including the scale-back in access to energy, the impediment to economic activity and the extra burden on government budgets. Market responses varied but governments were quick to react as the challenges of security of supply became apparent. Post-crisis, markets must continue to adapt as the effects of the crisis continue to influence security of gas supply…
