Sustainable energy
Sustainable energy is energy that is created in an environmentally friendly way. It involves both energy efficiency and renewable energy. Both resources help to stabilize and reduce carbon dioxide emissions.[1]
Efficient energy use allows energy demand to slow so that rising clean energy supplies can make big cuts in fossil fuel burning. If energy use grows too fast, renewable energy development will chase a receding target. Unless clean energy supplies grow rapidly, slowing demand growth will only begin to reduce total emissions. Reducing the carbon content of energy sources is also needed.[2]
Any serious vision of a sustainable energy economy thus requires major commitments to both efficiency and renewables.[2]

- Global primary energy consumption, OWID.svg
The use of modern renewable energy sources increased from 2000 to 2019 but coal, oil, and natural gas remain the most-used global energy sources.

Deaths caused as a result of fossil fuel use (areas of rectangles in chart) greatly exceed those resulting from production of sustainable energy (rectangles barely visible in chart).

- Energy use per person 2019 - OWID.svg
Global energy usage is highly unequal. High income countries such as the United States and Canada use 100 times as much energy per capita as some of the least developed countries in Africa.
- 2015- Investment in clean energy - IEA.svg
Clean energy investment has benefited from post-pandemic economic recovery, a global energy crisis involving high fossil fuel prices, and growing policy support across various nations. By 2025, investment in the energy transition had grown to about twice that for fossil fuels (oil, natural gas and coal).
