In 2024, the U.S. energy sector ushered in a landmark shift: wind and solar generated more electricity than coal for the first time, marking a key step on the path to energy transition for the United States. This event not only reflects the profound changes in the energy structure of the United States, but also reflects the general trend of global energy transition. China Exportsemi will deeply analyze the background, causes, impacts and future prospects of this event, and strive to present readers with a comprehensive and profound picture of the energy transition in the United States.
1. Background of the event: the inevitable trend of energy transition
As the global focus on climate change intensifies, countries are accelerating the pace of energy transition. As one of the world's largest energy consumers, the adjustment of the energy structure of the United States has an important global influence. In the past, coal has been an important pillar of the U.S. electricity supply, but due to the combination of environmental pressures, policy guidance, and market forces, coal power generation has gradually lost its advantage.
According to a new report by energy think tank Ember, wind and solar will account for 17% of electricity generation in the United States in 2024, surpassing coal for the first time at 15%, a record low. According to the U.S. Energy Information Administration, solar will be the fastest-growing source of electricity in 2024, accounting for 81% of new annual generation capacity, with a record 31 GW of new utility-scale solar capacity added. Wind power is growing relatively modestly, but it still generates twice as much electricity as solar and accounts for about 10% of the U.S. electricity mix.

2. Cause analysis: multiple drivers of policy, technology and market
(1) Policy support: an accelerator for energy transition
In recent years, the U.S. government has introduced a series of policies to promote the development of renewable energy. The Inflation Reduction Act (IRA) provides a large number of financial incentives and tax incentives for clean energy projects such as solar energy, which has greatly stimulated the market's enthusiasm for investment in renewable energy. In addition, state governments have also formulated renewable energy development targets and related policies, providing strong policy guarantees for the development of wind and solar energy.
(2) Technological progress: a key factor in reducing costs
The continuous progress of solar and wind energy technology is an important technical support for the growth of its power generation. The increasing conversion efficiency of photovoltaic modules and the significant reduction in costs have made solar power generation more economically competitive. In 2020, solar energy became the cheapest source of electricity in much of the world. Wind energy technology is also constantly optimized, with the capacity of wind turbines increasing and the power generation efficiency increasing, further reducing the LCOE of wind power.
(3) Market demand: the internal driving force of energy structure optimization
With the increasing demand for clean energy, power companies and enterprises have increased investment and development of wind and solar energy in order to meet the market demand for green energy. At the same time, consumers' preference for clean energy is also gradually increasing, which provides a broad market space for the development of the renewable energy market.
3. Impact analysis: reshaping the energy landscape and environmental benefits
(1) Reshaping the energy pattern
Wind and solar power generation surpass coal, meaning that the U.S. energy landscape is changing profoundly. Renewable energy is becoming an increasingly prominent part of the U.S. electricity supply and is gradually becoming an important part of the energy mix. This will not only help reduce dependence on traditional fossil fuels and improve the security and stability of energy supply, but will also have an important impact on the global energy market.
(2) Significant environmental benefits
The large-scale application of renewable energy is of great significance for reducing greenhouse gas emissions and addressing climate change. Coal power generation is one of the main sources of carbon dioxide emissions, while wind and solar energy, as clean energy sources, produce almost no carbon emissions in the process of generating electricity. Therefore, the increase in wind and solar power generation will effectively reduce the carbon intensity of the United States and contribute to the achievement of global climate goals.
4. The future outlook: opportunities and challenges coexist
While the U.S. has made significant progress in wind and solar development, it still faces some challenges. On the one hand, the intermittent and unstable problems of renewable energy need to be solved through energy storage technology, smart grids and other means to improve the reliability and stability of the energy system. On the other hand, policy uncertainty, international trade frictions and other factors may also have a certain impact on the development of renewable energy.
However, the opportunities are just as great. Wind and solar energy are expected to continue to grow their market share in the future as technology continues to advance and costs are further reduced. In addition, the U.S. is also improving its renewable energy manufacturing capacity, such as Texas, which has grown significantly in the field of solar module manufacturing, becoming the state with the strongest solar manufacturing capacity in the United States. This will help strengthen the United States' independent and controllable ability in the renewable energy industry chain and provide stronger support for the future energy transition.
5. Conclusion: The sustained momentum of the energy transition
In 2024, the United States will generate more wind and solar power than coal for the first time, which is an important milestone on the road to energy transition in the United States. Behind this incident is the combined effect of multiple factors such as policy support, technological progress and market demand. Despite some challenges, the prospects for the development of renewable energy remain promising. In the future, the United States needs to continue to increase investment in renewable energy research and development, improve the relevant policy system, and strengthen international cooperation, so as to promote the energy transition to a deeper and broader field and contribute more to global sustainable development.
