Renewable Energy Reaches a Milestone
Renewable Energy Surges: A Milestone Reached
Renewable energy made history in 2023, surpassing 30% of the world's electricity supply for the first time. This significant milestone is the result of a meteoric rise in wind and solar power, according to a new report. The report's findings suggest a potential turning point in the global energy landscape – fossil fuel generation may finally be on the decline, even as electricity demand continues to increase.
Clean energy initiatives have played a major role in slowing fossil fuel growth, reducing its expansion by nearly two-thirds over the past decade. This shift is largely driven by the renewable sector, which has expanded from 19% of global electricity generation in 2000 to over 30% last year.
"The era of renewable energy dominance has arrived," Dave Jones, Ember's director of global insights, emphasizes. "Solar, in particular, is advancing at a pace that has exceeded all expectations."
Solar energy emerged as the driving force behind this growth in 2023. In fact, it added more than double the amount of new electricity generation compared to coal. 2023 marked the 19th consecutive year of record solar growth and solar became the primary source of new electricity for the second year running, overtaking wind power.
Ember's comprehensive analysis of global electricity data covers 80 countries, accounting for a remarkable 92% of the world's electricity demand. Additional historical data from 215 countries further reinforces these findings.
Tackling Climate Change: The Role of Renewables and Emission Reductions
The surge in clean electricity could trigger a 2% reduction in global fossil fuel generation in the year ahead. "The decline of power sector emissions is a matter of when, not if," Jones asserts. "2023 was likely the pivotal year – marking peak emissions in the power sector, a significant milestone in energy history. However, how quickly emissions fall will depend on the continued rapid expansion of the renewables sector."
While fossil fuel usage may start to decrease within the power generation sector, it remains a dominant force in other energy-intensive areas such as transport, heavy industry, and heating. A separate Energy Institute study found that in 2022, oil, gas, and coal still accounted for 82% of the world's primary energy consumption.
To combat climate change, world leaders set an ambitious goal at the UN's Cop28 climate conference: increase renewable energy to 60% of global electricity by 2030. Achieving this would require nations to triple their current renewable energy capacity within six years, potentially slashing power sector emissions by nearly half.
Unprecedented Acceleration: Solar and Wind at the Forefront
The speed of the clean energy revolution has taken many by surprise. Moreover, forecasts suggest even more rapid gains in the years to come.
