Global investment in energy transition technologies reached an all-time high of $2.1 trillion in 2024, according to BloombergNEF. This marked an 11% increase from the previous year, driven by EVs, renewable energy, and advanced grid infrastructure. While the record-breaking investment highlights growing momentum toward cleaner energy solutions, experts caution that current funding levels fall far short of what’s needed to meet global climate targets.

Countries are ramping up investments in low-carbon energy to tackle climate change and meet Paris Agreement targets. However, experts warn that the current spending pace isn’t enough.

Bloomberg’s latest Energy Transition Investment Trends report shows that to hit net-zero emissions by 2050, global investment needs to triple to $5.6 trillion annually between 2025 and 2030. The gap is massive, highlighting the urgent need for bigger commitments and faster action.

Why do Energy Transition Investments Matter for Net Zero?

The energy sector plays a crucial role in addressing climate change as it contributes to approximately 75% of global greenhouse gas emissions. With temperatures rising every year, this transition to clean energy has become increasingly urgent.

Countries have committed to reducing emissions sustainably, aiming to keep global temperature rise below 2°C and limiting it to 1.5°C. The Paris Agreement target would be fulfilled only when the energy sector can reach net zero emissions by 2050.  

This transition significantly requires phasing out fossil fuels fairly and systematically while eliminating inefficient fossil fuel subsidies that hinder transition.

Closing the Funding Gap  

Now talking about the key factor i.e. investments. Governments and businesses are focusing on sustainable solutions like electric vehicles (EVs) and renewable energy. This certainly gives a positive signal towards developing a low-carbon economy.

However, there’s a funding gap. As said before, global investments in energy transition technologies reached $2.1 trillion. Yet, this amount is only 37% of the annual $5.6 trillion required from 2025 to 2030 to meet net-zero targets.

Achieving the net zero target will require not only increased funding but also bold policies and stronger international cooperation. Governments will need to be more decisive in scaling up efforts, remove barriers, and foster innovation across energy sectors.

For instance, accelerating progress in renewable energy, electrified transport, and grid modernization. With faster progress the funding gap can close and combating climate change will be easier.

Which Sector Took the Lead?

The report revealed that last year electrified transport topped the charts, pulling in $757 billion in funding. This includes investment in electric cars, commercial EV fleets, public charging networks, and fuel cell vehicles. With the EV market booming, it’s clear the world is betting big on cleaner mobility solutions.

Renewable energy also performed well. Globally $728 billion was invested in wind, solar, biofuels, and other green power sources. Additionally, power grid modernization secured $390 billion for upgrades like smarter grids, improved transmission lines, and digital tools to manage energy demand. Nuclear investment was flat at $34.2 billion.

In contrast, investment in emerging technologies, like electrified heat, hydrogen, carbon capture and storage (CCS), nuclear, clean industry and clean shipping, reached only $155 billion, for an overall drop of 23% year-on-year.

Investment in these sectors was hampered by affordability, technology maturity, and commercial scalability. Thus, the public and private sectors must work together to progress these technologies to reduce emissions.

Mature vs. Emerging: Where Clean Energy Investments Stand

Bloomberg further categorized investments into “mature” and “emerging” sectors. Mature technologies like renewables, energy storage, EVs, and power grids dominated funding while emerging sectors such as hydrogen, CCS, electrified heating, clean shipping, nuclear, and sustainable industries lagged.

• The mature Sector attracted $1.93 trillion in investments, accounting for the bulk of global energy transition funding.
• The emerging sector closed $154 billion in investments, making up just 7% of the total.

Despite facing challenges like higher interest rates and changing policies, mature technologies saw steady growth, increasing by 14.7% compared to the previous year. Their proven scalability and established business models make them trustworthy for governments and investors.

In contrast, emerging technologies faced significant setbacks. Investment in these sectors dropped by 23%, mainly due to high costs, unproven scalability, and limited commercial readiness. These challenges continue to slow their progress and hinder their potential to scale effectively

China Leads the Energy Investment Race

In 2024, mainland China emerged as the top market for energy transition investment, contributing $818 billion—a 20% rise from the previous year. This growth accounted for two-thirds of the global increase, with sectors like renewables, energy storage, nuclear, EVs, and power grids seeing robust development. China’s total investment surpassed the combined contributions of the US, EU, and UK.

Notably, China’s energy investment now equals 4.5% of its GDP, outpacing other nations like the EU and the US. While the US remains the second-largest market with $338 billion, Germany took third place, investing $109 billion in clean energy.

Other players like India and Canada also contributed to the global growth story, increasing investments by 13% and 19%, respectively.

2035 Forecast: A 3.6X Surge in Clean Energy Spending

To conclude Bloomberg came up with an investment forecast for 2030. The report says clean energy spending is set to rise sharply after 2030.

• Between 2031 and 2035, annual investments are projected to reach $7.6 trillion—3.6 times higher than 2024 levels.
• This marks a 37% increase compared to the annual spending expected between 2025 and 2030.

Electrified transport, including EVs and charging infrastructure, will continue to dominate investments during this period. As demand for clean mobility grows, funding for these technologies is likely to accelerate further, supporting the transition to a low-carbon future.

Thus, this steep rise in renewable energy spending after 2030 highlights the necessity for quick action. However, this year with Trump taking over, his stance on clean energy investment has been mixed. He has continued to promote traditional energy sources over clean energy, aligning with his “America First” agenda.

For 2025, the world is yet to get a clear picture of trade tariffs and clean energy funding with shifting political priorities and global economic uncertainties.
