Why are renewable energy projects now cheaper than fossil fuels?

Thanks to technological advancements, economies of scale, and policy support, the cost of solar and wind energy has dropped significantly—making them more affordable than fossil fuels in 91% of new projects.

Which renewable energy sources are most cost-effective?

Solar photovoltaic (PV) and onshore wind are currently the most cost-effective renewable energy sources, with costs having dropped by over 80% and 60% respectively in the past decade.

What are the main benefits of switching to renewable energy?

Renewable energy reduces carbon emissions, lowers air pollution, improves public health, creates jobs, and is now often more affordable than fossil fuels.

Are developing countries benefiting from cheaper renewables?

Yes, developing nations can leapfrog fossil fuel infrastructure and adopt affordable, clean energy systems to meet growing energy demands sustainably.

What challenges remain in the transition to clean energy?

Challenges include upgrading grid infrastructure, expanding energy storage, and updating regulatory frameworks to support a renewables-based energy system.

Clean Energy Wins: 91% of New Renewables Now Cheaper Than Fossil Fuels

The global energy transition has reached a critical tipping point. According to recent data, 91% of new renewable energy capacity added in 2024 is now cheaper than electricity generated from fossil fuels. This marks a major shift in the economics of power generation. Below are five key reasons why clean energy is taking the lead:

1. Drastic Cost Reductions in Solar and Wind

The cost of solar photovoltaic (PV) and onshore wind has dropped by over 80% in the past decade. These improvements have made renewable energy the most affordable new source of electricity in many parts of the world, especially in developing markets.

2. Rising Fossil Fuel Volatility

Fossil fuel prices have become highly volatile due to geopolitical risks and market disruptions. Renewable energy offers price stability, as it relies on natural resources like sunlight and wind, making it a more predictable and secure option for investors and governments.

3. Supportive Policies and Green Incentives

Governments are accelerating renewable deployment with subsidies, tax incentives, and green energy auctions. Programs like the U.S. Inflation Reduction Act and the EU Green Deal are creating a favorable policy environment for clean energy investments.

4. Private Sector Leadership

Corporations are playing a key role by signing Power Purchase Agreements (PPAs) with renewable energy developers. Driven by net-zero targets and ESG goals, businesses now see renewables as both a sustainable and cost-effective energy solution.

5. Environmental and Health Imperatives

Switching to clean energy reduces air pollution, cuts greenhouse gas emissions, and improves public health. These non-financial benefits are increasingly influencing policy decisions and public opinion in favor of renewable adoption.

Conclusion

With 91% of new renewables now undercutting fossil fuels on price, the economic case for clean energy has never been stronger. As technologies evolve and global support intensifies, renewable energy will continue to drive the future of sustainable development.
