A New Era for the Global Energy Transition
In the first half of 2025, for the first time in history, renewable energies, solar and wind, generated more electricity than coal.
According to the independent think tank Ember Energy, this milestone marks a decisive step in the global energy transition.
This shift also reinforces the crucial role of satellite solutions for optimizing renewable energy infrastructure, essential to supporting the growing offshore wind sector.
Global Energy Report 2025: An Energy and Digital Turning Point for Renewable Infrastructure
According to Ember’s latest “Global Electricity Review” and mid-year data, the global power system has entered a new structural phase driven by exponential renewable growth. In the first half of 2025, worldwide electricity demand grew by +2.6% (≈ 369 TWh), and this increase was fully supplied by clean energy sources. Solar alone contributed an estimated 306 TWh (+31% Y/Y), while wind added ≈ 97 TWh (+7.7%).
Together, solar and wind reached ≈ 5,072 TWh, surpassing coal at ≈ 4,896 TWh, a historic milestone marking the first time renewables have overtaken coal in global electricity generation.
Ember’s analytical framework covers 215 countries, with complete datasets for 88 countries representing ~93% of global electricity demand, combining meteorological, capacity, and generation data to reveal the system’s underlying dynamics.
These capabilities enable offshore developers to increase performance, reduce operational risks, and maximize long-term asset value.
Satellite solutions for optimizing renewable energy infrastructure strengthen continuous environmental monitoring, asset surveillance, and operational decision-making.

The Technical Challenges of rapid Offshore Growth
Offshore Renewable Infrastructure: The New Frontline of the Energy Transition
Despite significant progress, several regions, particularly Europe and the United States, continue to struggle with reliance on fossil fuels. Key barriers include limited storage capacity, rigid power grids, and insufficient flexibility to manage renewable intermittency.
Addressing these challenges requires modernized energy infrastructure and the integration of real-time data.
In the offshore sector, this means more accurate site qualification, continuous environmental monitoring, and optimized logistics chains.
CLS: Ocean Intelligence and Satellite Solutions for Renewable Infrastructure
At the heart of this transformation, CLS deploys satellite solutions for optimizing renewable energy infrastructure, combining SAR imagery, in situ data collection, and advanced ocean-atmosphere modelling.
