Large-scale decarbonization is not possible without regulatory support. While recent policy momentum is accelerating progress in renewable energy deployment, there is significant discrepancy across nations. Leaders are driving clean-energy adoption through strong frameworks and funding mechanisms.
The World Economic Forum’s Fostering Effective Energy Transition 2025report considered factors such as regulation, political commitment, investment, innovation, and infrastructure to compare and rank nations in the Energy Transition. Leaders include the United States, China, and the European Union, and have set robust, concrete targets (e.g., 42.5% renewable-energy share in the EU energy mix by 2030) with notable funding and enforcement mechanisms (e.g., 45V Hydrogen Credit in the USA). These countries have been investing in and incentivizing renewables for over 5 years, with some regulatory foundations established decades earlier. For example, in the United States, renewables regulation dates back to the Energy Tax Act of 1978, which provided a residential energy tax credit for solar and wind equipment. For China, the Renewable Energy Law from 2005 promoted the development of renewables to accelerate the protection of the environment. Looking ahead, these leading countries are expected to continue scaling investment and refining policy frameworks to meet their long-term energy-transition targets.
By contrast, emerging economies such as India and Russia have outlined future ambitions but have fewer comprehensive targets and enforcement frameworks. While noble, the lack of concrete mechanisms to fund and/or incentivize production have ensured that development has been largely constrained (especially relative to leaders). However, these countries are expected to invest more in renewable energy over the next 5 to 10 years as global pressures and domestic energy needs intensify.
Today, global energy investment is primarily concentrated in renewable electricity generation, electrified transport, and power-grid upgrades. This concentration is apparent across nations, where policies have most often sought to subsidize conventional renewables, fund grid upgrades, and subsidize electrified transport. Between 2022 and 2024, total global renewables investment grew 17%, rising from $1.5 to $2.1 trillion. To align with the International Energy Agency’s Net Zero scenario, investment will need to grow over 2.5-fold in the next few years, increasing from $2.1 trillion in 2024 to $5.6 trillion by 2030.
While renewable energy remains a significant category, electrified transport (primarily outside of the USA) is expected to experience outsized growth, driven by rapid EV adoption across passenger and commercial fleets, continued expansion of charging infrastructure, and ambitious OEM sustainability commitments. Overall, this reflects electrified transport investment increasing fourfold by 2030, equivalent to a CAGR of about 29% each year.
Looking ahead, three major structural shifts are expected to define the next phase of the global energy transition.
First – the integration / buildout of energy storage. As electricity demand has skyrocketed due to a combination of electrification, rapid expansion of data centers, and energy-intensive agentic AI workloads, significant investment has begun being allocated towards grid expansion. Yet, a critical gap in this electrification push lies in energy storage, which is essential for both alleviating grid capacity constraints and enabling renewables deployment.
Second – the national-security driven shift towards localization of clean-technology supply chains, particularly in batteries, critical minerals, and advanced materials. This is supported by domestic manufacturing incentives and national energy-security legislation, such as the EU’s Critical Raw Materials Act, or the U.S. Inflation Reduction Act’s advanced manufacturing production credit.
Finally, standardized carbon accounting and coalitions such as the business-led Carbon Measures (October 2025), which includes BASF, ExxonMobil, and EY, will drive transparency and incentivize low-carbon production. Together, these shifts signal a maturing transition, where policy, technology readiness, and industrial strategy accelerate investment and reshape global energy systems.
