Wind
Wind has significant potential to boost growth in global renewable capacity
Electricity generation from renewables is expected to increase by 60% through 2030 – rising from 9 900 terawatt-hours (TWh) in 2024 to 16 200 TWh by the end of the decade. Wind accounts for almost a third of growth, second only to solar PV, which accounts for 60%.
Although wind power continues to face supply chain issues, rising costs and permitting delays today, global capacity is still expected to nearly double to over 2 000 gigawatts (GW) by 2030 as both advanced and developing economies tackle these barriers.

Hydroelectricity
Hydropower is the largest source of renewable energy today, but that could change soon
Hydro is currently the third largest source of power generation worldwide after coal and natural gas. In 2024, it generated around 4 500 terawatt-hours of electricity, or 14% of the global total.
More than 150 gigawatts (GW) of new hydro capacity is set to come online by the end of the decade, mostly in emerging and developing economies. As a result, electricity generation from hydropower is expected to increase by 7% between 2025 and 2030. However, its share in global electricity generation is poised to…

Building Envelopes
Stronger efficiency is the first and best policy to bring down energy bills
Variations in energy efficiency exist both within and among countries. For example, in some European countries with similar climates it can take twice as much energy to heat the same floor area or within one country the energy consumed between the most efficient and least efficient homes for a given size can vary by a factor of up to three.

Gas Flaring
CO2 emissions
The volumes of natural gas flared in 2022 were around the same level as in 2010
Technology deployment
Oil producers have a range of readily available options to reduce and avoid flaring, with a number of new technologies also under development
Policy
A number of countries have introduced policies to reduce flaring
Investment
Operators that sell high-flaring assets are often passing on a problem to other operators that may be less willing, or less able, to cut down on flaring

Light Industry
Country and regional highlights
Important investment programmes are being deployed to push energy efficiency and decarbonisation in light industries
CO2 emissions
While light-industry emissions have declined since 2010, a more rapid decline is needed to get on track with the NZE Scenario
Energy
The share of fossil fuel use is declining, but progress needs to accelerate
Technology deployment
Firms should prioritise technologies for low-emission process heat and increased energy efficiency
