In 2025, renewable energy is undergoing its most transformative period since the dawn of the clean power revolution. Global investment in renewables surpassed £1.7 trillion this year, with new technologies redefining efficiency, affordability, and scalability. From artificial intelligence in grid forecasting to next-generation solar cells, emerging solutions are enabling a cleaner, smarter, and more resilient energy future.

According to two new United Nations reports released in July 2025, the world has officially passed a “positive tipping point” in the shift to renewable energy. UN Secretary-General António Guterres hailed the milestone as a defining moment, announcing that “the fossil fuel era is flailing and failing” as solar and wind power dominate new global electricity capacity. Together, renewables accounted for over 92% of new electricity generation added to the global grid in 2024—an unprecedented record that confirms clean energy’s irreversible momentum.

Labour’s defining environmental pledge—to deliver a fully decarbonised electricity grid by 2030—is under serious strain. Prime Minister Keir Starmer faces mounting criticism following reports that his government may abandon the clean power deadline amid efforts to stabilise energy prices. Sources inside the government told outlets such as The Guardian that Starmer is “prepared to miss” the 2030 target if it proves significantly more expensive than maintaining gas generation capacity. The tension sits at the centre of Labour’s energy policy: lowering household bills while rapidly expanding renewable production.

In October 2025, the UK Government unveiled its landmark Clean Energy Jobs Plan, committing to create 400,000 new green sector jobs by 2030. This bold initiative represents the country’s largest ever nationwide effort to mobilise skilled labour for the clean energy transition, doubling employment in renewables, nuclear, and associated industries from 440,000 in 2023 to an estimated 860,000 by the end of the decade. With £50 billion in public and private investment already announced since July 2024, the plan seeks to place Britain at the forefront of the global green jobs boom.

Global coal consumption smashed previous records in 2024, hitting an unprecedented 8.77 billion tonnes despite significant gains in renewable energy worldwide. This record, confirmed by the International Energy Agency (IEA), resulted from surging electricity demand, especially from emerging economies such as China and India, which faced exceptional heatwaves necessitating mass cooling. The absolute amount of coal burned rose sharply, even as its share of the global energy mix diminished—from 37% in 2019 to 34% in 2024—highlighting the immense challenge in limiting its use despite clean energy expansion.

Britain has achieved a historic milestone in the third quarter of 2025, as renewable energy generation soared to a record 31.9 terawatt hours (TWh), driven predominantly by exceptional wind and solar power output. For the first time in a Q3 period, renewables supplied 51% of Britain's electricity demand, overtaking all fossil-fuelled sources combined and confirming the country's status as a leader in the global clean power transition.

The World Meteorological Organization (WMO) has unveiled disturbing evidence in its latest greenhouse gas bulletin that carbon dioxide levels in the atmosphere reached unprecedented heights in 2024, jumping by the largest single-year increase since modern measurements began in 1957. The global average concentration of CO2 surged by 3.5 parts per million (ppm) between 2023 and 2024, with atmospheric levels now standing at 423.9 ppm—a staggering 52% increase above pre-industrial levels.

The world witnessed unprecedented growth in renewable energy over the last two years, with 2024 setting a global record for new installations. A staggering 582 gigawatts (GW) of new renewable capacity was added worldwide in 2024—a 15.1% increase from the previous year—propelled by a surge in solar photovoltaics and expanding offshore wind farms. Investment followed suit, with clean energy set to attract $2.2 trillion in 2025—twice as much as fossil fuels.

Hydrogen blending involves mixing green hydrogen with traditional natural gas and using this combination to generate electricity for the national power grid. The UK's first real-world hydrogen blending trial, carried out in October 2025, represents a significant advancement towards decarbonising the country's energy infrastructure. By introducing green hydrogen into the existing gas grid, the process demonstrates how legacy energy systems can be adapted for a low-carbon future without major new investment.
