Strides to a better future

The data presented in the renewable energy cost chart reveals one of the most remarkable economic transformations of the 21st century.

Between 2014 and 2024, the cost of renewable energy technologies has plummeted at unprecedented rates, fundamentally reshaping the global energy landscape and making clean energy not just an environmental imperative, but an economic winner.

Wind Energy follows the trend

Wind energy has followed a similar trajectory, with onshore wind costs declining by 64% and offshore wind by 58%, demonstrating that technological advancement and economies of scale have created a virtuous cycle of affordability.

This cost revolution is particularly evident across Europe, where countries have leveraged these declining costs to accelerate their energy transitions. Portugal stands as a remarkable success story, averaging 91% renewable electricity in 2024 with Europe's lowest power prices, while renewables supplied 71% of the country's total electricity needs. This represents extraordinary progress from just 27% in 2005 and 54% in 2017.

The Many Benefits

Spain has recently established a comprehensive regulatory framework for offshore wind power through Royal Decree 962/2024, positioning itself to benefit from the technology's cost reductions. Meanwhile, Germany continues to lead European deployment with 4 GW of new wind capacity installed in 2024, supported by continued cost competitiveness.

The economic benefits extend beyond generation costs. In 2024, renewables helped avoid $467 billion in fossil fuel costs, showing how renewable energy deployment has provided crucial protection against volatile fossil fuel prices. However, some markets have experienced temporary cost pressures, with global average levelised costs for onshore wind and solar PV remaining 10-15% above 2020 levels in 2024 due to supply chain disruptions and inflation.

Europe's decreasing costs

The Netherlands has also capitalized on falling costs, with renewable electricity production reaching 53% of total electricity generation in 2024. The country's ambitious offshore wind program expects 75% of all electricity to come from North Sea wind farms by 2032, building on its current 4.7 GW of installed offshore capacity.

The United Kingdom has emerged as a major player in offshore wind development, with the UK building 1.9 GW of new wind capacity in 2024, ranking second only to Germany. Wind now accounts for 30% of the UK's electricity mix, demonstrating how declining costs have enabled large-scale deployment

Benchmarks

Perhaps most significantly, 91% of all newly-commissioned, utility-scale renewable capacity delivered power at a lower cost than the cheapest new fossil fuel-based alternative in 2024. Global renewable energy capacity grew by a record-breaking 15.1% in 2024 to reach 4,448 gigawatts, with an additional 585 GW of power added, largely due to solar and wind energy expansion.

This milestone represents a fundamental shift where renewable energy is no longer subsidized by environmental concerns alone but is chosen purely on economic merit, creating a self-reinforcing cycle of investment, innovation, and deployment that continues to accelerate the global transition to clean energy.
