Low-Carbon Power: Monitor the Growth of Low Carbon Energy
Most Popular Pages
In 2025, the landscape of global electricity consumption shows that more than half of the world's electricity is generated from fossil fuels, accounting for roughly 57%. Coal remains a dominant source, contributing nearly a third to overall electricity production, while natural gas covers just over a fifth. In contrast, low-carbon energy technologies constitute about 43% of the electricity supply, playing a crucial role in paving the way for a more sustainable future. Hydropower stands out within this group, providing roughly 14%, tied with solar energy, which remarkably contributes almost 9%. Similarly, nuclear energy is a key player, generating nearly 9%, closely aligned with the considerable share garnered by wind power at around 9%. Biofuels, while they enhance the low-carbon portfolio, represent a minor slice, just below 2%.

Is Electricity Growing in The World?
Recent trends in global electricity consumption indicate a worrying decline rather than growth, with the consumption average dropping to 3412 kWh per person in 2025 from the previous year's 3662 kWh per person—a decrease of 251 kWh. This downturn extends to low-carbon electricity per person, which saw a drop from 1511 kWh to 1469 kWh. Given these numbers, it's clear that the world is experiencing a setback in expanding its electricity consumption, especially from green sources, which is critical in fostering a more sustainable future. In this era of increasing demand driven by the electrification of transport and industries, as well as the burgeoning field of AI, declining electricity use is an alarming trend that needs urgent attention and redress.
Suggestions
Looking towards ways to enhance low-carbon electricity generation, the world can glean valuable insights from regions thriving in specific technology areas. For instance, France and Slovakia have demonstrated considerable success with nuclear power, achieving over 65% of their electricity from this clean source. Similarly, countries like Denmark and US states like Iowa and South Dakota showcase impressive achievements in wind energy, deriving around 60% of their electricity from it. Solar energy, while still ramping up in many regions, has shown potential in places like Nevada, Lebanon, and California, achieving around 31% to 34%. These examples underline the importance of tailored solutions harnessing abundant local resources, be it wind, solar, or nuclear, and highlight the potential for scalable energy transitions worldwide.
History
Historically, the trajectory of low-carbon electricity has seen varied phases. In the late 20th century, nuclear energy experienced significant growth, particularly in the mid-1980s, marked by increases exceeding around 200 TWh annually. The 1990s saw hydroelectric gains contributing to substantial low-carbon energy involvement. However, the 21st century has been a mixed bag; while wind and solar have flourished, particularly from 2020 onwards, nuclear energy has faced setbacks including significant declines in 2011 and 2022, with further downturns in 2025. Despite these setbacks, the recent explosive growth in solar and wind capacity suggests a positive trajectory. This underlines the tremendous potential for clean electricity across the globe, emphasizing the need for continued investment and policy support, particularly to revitalize and harness nuclear power alongside the burgeoning solar sector to achieve a sustainable green energy future.
