The energy transition is often framed as a choice between LNG and renewables, but the reality is far more complex. As global energy demands rise, the most effective approach involves creating synergies between traditional fossil fuels and renewable technologies. In a recent article, I explore how oil and gas can complement renewables by stabilizing grids, ensuring consistent supply, and supporting the development of energy storage solutions. The future of energy is not about choosing one or the other; it’s about leveraging both to drive faster, more sustainable progress toward a low-carbon future.
