Key Questions on Energy and AI Executive summary
The AI and energy nexus continues to evolve rapidly The largest technology companies are contributing to a surge in data centre investment, as their capital expenditure exceeded USD 400 billion in 2025 – and is expected to jump by another 75% in 2026. Capital expenditure of just five technology companies is now larger than global investment in oil and natural gas production. Many jurisdictions are seeing project pipelines accelerate dramatically, although not all projects will come to fruition. Those that are moving forward are doing so at pace: the IEA’s unique satellite-based tracking shows that “artificial intelligence (AI) factories…

Global Methane Tracker 2025 Understanding methane emissions
Methane concentration in the atmosphere continues to rise The concentration of methane in the atmosphere is now over two-and-a-half times above pre-industrial levels. Atmospheric records show that, in relative terms, methane concentrations have been rising more quickly than those of all other major greenhouse gases – and at a rate faster than in any period since recordkeeping began. This growth is mainly due to mounting emissions from human activity, but there are also indications that a warming climate is driving up emissions from natural sources such as wetlands. Methane is responsible for around 30% of the rise…

Multiple Benefits of Energy Efficiency for Business The business value of energy efficiency
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone, improving margins and reducing exposure to price volatility.However, the value of energy efficiency extends beyond energy savings. By improving how equipment, buildings and processes operate, efficiency measures deliver wide-ranging benefits that strengthen business competitiveness across several dimensions: Operational benefits Efficient and electrified equipment operates more reliably and with less stress…
