Policy Reversals in the US will Only have a Marginal Impact on the Global Energy Transition – Report

The global shift towards cleaner energy remains robust even though the pace of the energy transition in the United States has slowed sharply due to recent policy reversals. According to the ninth edition of DNV’s Energy Transition Outlook, the US slowdown will have only a marginal effect on worldwide progress, as momentum continues to build elsewhere - most notably in China.

In the US, policy reversals and renewed support for fossil fuels are expected to delay emission reductions by about five years, with annual CO₂ emissions projected to be 500 to 1,000 million tonnes higher than previously forecast. Meanwhile, China is setting new records for renewable energy deployment, accounting for 56% of global solar PV installations and 60% of new wind power additions this year alone. Its clean technology exports also continue to drive the energy transition worldwide.

DNV forecasts a slightly slower transition with the energy mix to be split 51%-49% between fossil and non-fossil fuels in 2050. Likewise, 2050 global CO2 emissions are now forecast to be 4% higher compared to last year’s Outlook.

“It is more important than ever to evaluate the energy transition from a global perspective. The global energy transition is not stalling — it is evolving, with momentum shifting to regions that are doubling down on clean technologies,” said Remi Eriksen, Group President and CEO of DNV. “Security has become the dominant driver of energy policy, and as our forecast shows, this is in sum accelerating the shift to renewables.”

The Energy Transition Outlook finds that the net effect of energy security is decreasing emissions. Global emissions are forecast to be 1-2% lower per year due to the implementation of energy security policy. Nuclear power, for example, will account for 9% of electricity supply in 2060. Without energy security policies, nuclear power would have been one third lower. In Europe, emissions are forecast to be 9% lower in 2050 due to energy security as it pivots away from imported fossil fuels.

Other key findings from this year’s report include:

• AI is emerging as a significant energy consumer, but it will only consume 3% of global electricity in 2040. Data centre energy use will quintuple to 2040, equalling 5% of all global electricity – 3% of this is for AI and 2% for general purpose data centres. There are large regional variations; in North America (the US and Canada) the 2040 share is 16% of all electricity, with 12% being AI.

• Global CO2 emissions will reduce by 43% from today to 2050 – and is expected to reach net zero after 2090. The carbon budget for 1.5°C is exhausted in 2029 and the budget for 2°C in 2052. Limiting global warming to 1.5°C without a temporary overshoot is no longer possible.

• Electricity is growing and greening at a high pace. Global electricity generation is projected to increase by 120% from now until 2060, doubling from a 21% share of total energy demand today to 43% in 2060. During 2025 we have passed the milestone of 50 million BEVs. Global solar PV capacity is projected to reach over 3000GW this year, with China having installed more than twice as much capacity as Europe, the next largest installer.

• The plunging costs of solar panels and batteries have made behind-the-meter (BTM) solutions attractive for a range of households and business. BTM will represent 30% of all solar and 13% of all power generated by 2060.

“In several sectors, technology progress and cost reduction are driving the energy transition forward, but in harder to decarbonize sectors, much more policy help is needed. While geopolitical tensions and national priorities add complexity, the global direction of the energy transition remains clear,” added Eriksen.

AI Models Can Now Reason with Live Weather Data – Vaisala Xweather First to Connect Them

Global weather intelligence provider Xweather has integrated Model Context Protocol (MCP), an emerging standard that allows AI models to access specialized data in real time. In doing so, Xweather becomes the first enterprise-scale solution to connect AI models, such as ChatGPT and Claude, to real-time meteorological data.

Xweather's weather intelligence platform is already trusted by leading organizations such as FedEx, Netflix, American Airlines, and 40% of Fortune 100 companies. With MCP integration, the potential implications for business and society are vast. Industries such as logistics, insurance, and renewable energy can use this data to make rerouting decisions, validate insurance claims, and optimize energy output. MCP integration makes these capabilities accessible through simple conversation – no custom development required.

“MCP integration represents a fundamental shift from weather as information to weather as intelligence,” said Lee Huffman, Director of Data as a Service at Xweather. “The implications extend beyond meteorology to any industry dealing with specialized, time-sensitive information that AI systems need but haven’t previously been able to access.”

Weather data moves from hindsight to foresight

Last year alone, weather-related disasters cost $182.7 billion in the U.S. As extreme weather events grow in frequency and intensity, the need to turn meteorological data into rapid, real-world decisions has never been greater.

Xweather's MCP integration makes enterprise-grade meteorological data available through natural language conversations, so insights normally reserved for trained meteorologists can now be accessed without knowledge of weather APIs or complex data formats.

Analyses that used to require multiple data sources, custom connectors, or manual processes now take a simple AI prompt:

"Was there lightning at 1247 Oak Street, Columbus, Ohio on August 15th? I need forensic-grade data for court." (insurance adjuster investigating a claim)
"Map the safest weather-aware route from Chicago to Miami this weekend. Flag wind advisories that could affect high-profile vehicles." (logistics coordinator planning truck routes)
"For our solar farm in Arizona, what hours tomorrow have the best balance of sun and low cloud cover? Give me a 6 a.m.–6 p.m. output curve prediction." (renewable energy operator optimizing power generation)

Additionally, MCP integration allows organizations to apply enterprise-grade weather intelligence into their own products and systems, enhancing services like voice-activated in-car assistants. Drivers could soon hear warnings such as: “Bridge ahead is frozen, adjust speed.”

“We're not just delivering data. We're enabling AI models to reason, respond, and act on weather conditions with unprecedented ease and speed," said Huffman. "This opens an entirely new way for companies to access weather intelligence. AI shifts from text generator to decision-making tool, and businesses that couldn't use weather data before now can. With MCP integration, we are reinforcing Xweather's commitment to climate resilience, data accessibility, and AI leadership”.

The MCP integration is now available for users with an Xweather API subscription.

Hithium Experiences Rapid Business Growth, Likely to Continue Hong Kong IPO by Year-End

Xiamen Hithium Energy Storage Technology Co. Ltd. is likely to restart its Hong Kong IPO process in the next three months, after its application filed earlier this year expired, as it seeks funds for its global expansion and ramps up its energy storage systems business.

The company's original March listing application lapsed late last month after it failed to complete the IPO within six months, a common occurrence for most companies in their first listing attempts, rather than a sign of failure. The development comes not long after a similar application by another energy storage company, Sigenergy, also expired after it failed to complete the listing within six months after filing.

A knowledgeable source told Chinese media that Hithium is likely to restart its Hong Kong IPO process by the end of this year.

The energy storage sector is currently thriving in the capital markets, attracting strong investor interest on strong growth prospects and supportive government policies. Hithium is seeking to tap booming global demand for both batteries and systems used to store energy from a growing number of solar, wind and other new energy farms and other generating stations being built worldwide. Such storage is a critical component for these facilities, allowing them to store excess electricity during peak generating times for later release during production lulls.

As demand ramps up, the global energy storage market is expected to pass 1,000 GWh per year by 2030, according to third-party market data in Hithium's original March prospectus.

Founded in 2019, Hithium provides batteries and energy storage systems for residential, commercial and industrial customers. It is the world's third largest provider in its sector, with about 11% of the global market. Its shipments grew by an average 167% annually between 2022 and 2024 to reach 35.1 GWh last year.

A recent boom in overseas demand for energy storage has helped Hithium to win multiple international orders from Europe, the U.S. and the Middle East, propelling it to second in global energy storage shipments in the first half of 2025. The company's two production bases in the cities of Xiamen and Chongqing have been operating at full capacity since March, and it is also building a new facility in the city of Heze in Shandong province to boost its capabilities. In a move to hedge against U.S.-China trade frictions, the company has already put a new facility in the U.S. state of Texas into operation — making it the first Chinese enterprise in this sector to establish and launch such a production base in the United States.

Hithium's revenue grew 26% last year to 12.9 billion yuan ($1.81 billion) from 10.2 billion yuan in 2023. Within that bigger figure, revenue from energy storage systems, which typically carry higher profit margins, more than doubled last year to 4.67 billion yuan from 1.97 billion yuan the previous year, rising to 36.2% of the total from 19.3% over that time.

The company is also rapidly building up its overseas business, which grew from just 1% of sales in 2023 to 28.6% last year. Hithium made a big advance on that front in August, when it signed a major supply deal with Saudi Electricity Co. worth about 2.6 billion yuan. On the bottom line, Hithium also passed another major milestone last year when it became profitable on an adjusted basis, reporting a 318 million yuan adjusted profit for the year.
