The research shows a win-win-win scenario, in which rapidly transitioning to clean energy results in lower energy system costs than a fossil fuel system, while providing more energy to the global economy, and expanding energy access to more people internationally. But clean energy costs have fallen sharply over the last decade, much faster than those models expected. Accelerating the transition to renewable energy is now the best bet, not just for the planet, but for energy costs too.’Accelerating the transition to renewable energy is now the best bet, not just for the planet, but for energy costs too Dr Rupert WayThe researchers analysed thousands of transition cost scenarios produced by major energy models, and used data on 45 years of solar energy costs, 37 years of wind energy costs and 25 years for battery storage. Completely replacing fossil fuels with clean energy by 2050 will save us trillions.’The study shows the costs for key storage technologies, such as batteries and hydrogen electrolysis, are also likely to fall dramatically. The current energy crisis underscores the study’s findings and demonstrates the risks of continuing to rely on expensive, insecure, fossil fuels.
