China is making rapid progress in scaling up clean energy, tentatively boosting hopes that the world’s largest carbon emitter could soon start to curb greenhouse gas pollution.
A massive wave of permits for new coal-fired capacity poses a significant challenge to the country’s climate goals, with Beijing seen as “the glaring exception to the ongoing global decline in coal plant development,” according to the Global Energy Monitor.
Research from the Center for Research on Energy and Clean Air and GEM published late last month showed China approved the highest number of new coal-fired plants since 2015 last year.
Beijing authorized 106 gigawatts of new coal power capacity in 2022, four times higher than a year earlier and the equivalent of 100 large-fired power plants, the research said.
The extraordinary speed at which China approved the projects was thought to have been driven by energy security considerations, namely electricity shortages following a historic drought and heatwave last summer.
The major additions of new coal-fired capacity may not necessarily mean that carbon emissions from the power sector will increase in China, CREA and GEM analysts said, particularly given the country’s rapid progress in scaling up clean energy.

China is recognized as the undisputable global leader in renewable energy expansion, adding new projects to the grid almost as fast as the rest of the world combined in 2022.
The build-out comes as part of the government’s strategy to cut its energy intensity and reach peak emissions “in a well-planned and phased way.”
“When we look around the world today, we can firmly see that the energy transition is in progress,” said Mike Hemsley, deputy director at the Energy Transitions Commission think tank.
“China is building renewables at such a staggering rate [that] it is said to outperform the targets they have set themselves,” Hemsley said at International Energy Week in London last week. He added that around 50% of all renewables built every year were built in China.
“To put that into context, we’ve heard the really admirable goal of Masdar to build 100 gigawatts of renewables by 2030 [but] China every year is building around 75 gigawatts of wind and in excess 100 gigawatts of solar every year,” Hemsley said. Masdar is the UAE’s state-owned renewables developer.
On its current trajectory, Hemsley said that Beijing is on track to reach 1,800 gigawatts of total renewables by 2030. That would be 50% higher than Chinese President Xi Jinping‘s target of 1,200 gigawatts of total renewables by the end of the decade.
“The implications of that being [that] they will outperform their Nationally Determined Contribution, and they are likely to peak emissions way before 2030, some say around 2025 [or] 2026,” Hemsley said, describing this as “really positive news.”
‘A hot, still summer evening is the worry’
The International Energy Agency said earlier this month that, while still rising, global carbon emissions may at least be reaching a plateau.
Energy-related carbon emissions added less than 1% in 2022 to a new high of more than 36.8 billion tons. The increase was less than expected, as renewables helped limit the impact of a global rise in coal and oil consumption. Comparatively, global emissions from energy gained by 6% in 2021.
China’s emissions, the IEA said, were broadly flat in 2022, as Covid-19 measures and declining construction activity led to weaker economic growth.
“Getting China’s emissions to peak has an indispensable role in peaking and declining global emissions — and the success of the overall global effort,” said Lauri Myllyvirta, lead analyst at CREA.
In 2020, China’s Xi announced plans for the world’s second-largest economy to strive for peak carbon emissions in 2030 and for carbon neutrality by 2060.
Myllyvirta told CNBC via telephone that, depending on one’s perspective, China’s climate targets could either be seen as flexible or as lacking in ambition, noting it is important to keep in mind that they allow for a “huge range of outcomes.”
“The grid planners believe that there are going to be some hours or days or weeks during the summer [when] they are going to need more coal-fired power plants,” Myllyvirta said.
China’s power system remains dependent on coal, the world’s dirtiest fossil fuel, to meet electricity peak loads and to manage the variability of demand and of clean power supply.
Burning fossil fuels, such as coal, oil and gas, is the chief driver of the climate crisis.
“A hot, still summer evening is the worry. Where are [they] going to get enough power to keep the lights on? That’s why they think they need more coal-fired power plants, because that’s traditionally the way they’ve met the demand in that situation,” Myllyvirta said.
If China is going to meet its climate commitments — as CREA expects — then the think tank says that the country’s new coal power plants will “end up as short-lived and under-utilized malinvestments.”
Thanks to a clever, fully electric swing system and “boom up” power assist features, the big PC365-11 hybrid excavator from Komatsu promises better performance and serious fuel savings compared to conventional diesel machines.
Komatsu says its PC365-11 hybrid excavator uses a “boom-up” power assist feature that captures and stores kinetic energy during different operation cycles, then taps into that power to provide an extra energy boost when needed. The result is 15% more productivity and a 20% improvement in fuel efficiency when compared to non-hybrid excavators in ~40 ton class.
“The PC365LC-11 was engineered for excellence in multifunction applications by leveraging its innovative electric powertrain system to boost job site productivity while reducing fuel consumption,” says Matthew Moen, Komatsu’s product manager. “To highlight these performance enhancements, we’re emphasizing the concept of ‘multifunction plus’ as the defining feature of this machine.”
How it works
Komatsu’s hybrid system replaces the conventional hydraulic swing function with a fully electric swing motor that draws power from an ultracapacitor (as opposed to a battery) energy storage unit. As excavator slows or stops swinging, something like a regenerative braking system captures the kinetic energy that would normally be lost as heat and stores it in the capacitor. Once there, the stored energy can be quickly released to power the swing motor or assist the engine, delivering up to an extra 70 hp when needed to support heavy lifting or digging cycles.
And, thanks to Komatsu’s proprietary software, all of this energy capture and reuse happens automagically during normal work, without the need for external charging. The fuel savings happen because removing the hydraulic load from the ICE engine allows it to run at an ultra-low idle, while the productivity comes from the greater power and overall speed of the electric operations vs. conventional hydraulics.
Electrek’s Take
Trust me when I tell you that Komatsu didn’t wake up one day and decide to build a capacitor-based hybrid crane. One of their customers had the idea and came to them, promising orders. That’s what Komatsu does – from undersea remote control dozers to lunar mining rigs (above), if you bring Komatsu an order, they will absolutely find a way to fill it.
As for PC365-11 hybrid excavator, it’s packed with clever tech, overall – offering significant fuel, emissions, and TCO reductions without dramatically changing the operational logistics of an existing fleet’s operations. That’s all the sales pitch it needs.

For serious fleet buyers, safety isn’t a “nice-to-have,” it’s an absolute must – and Kia’s new PV5 electric van meets that need with a positively stellar, five-star safety rating on the tough European NCAP safety test.
The new “do-it-all” Kia PV5 showed strong performance across a number of key safety categories, including Occupant Protection, Safety Assist/Crash Avoidance, and Post-Crash Safety. The PV5’s robust suite of standard ADAS technologies that includes AEB, Lane Support System, and Speed Assistance System also helped the new electric work van to deliver top marks in the NCAP’s “real world” test scenarios.
“The PV5 opens a new chapter in practical, electrified mobility, offering generous space and modular versatility for everyday use,” explains Sangdae Kim, Executive Vice President and Head of the (relatively) new PBV Business Division at Kia. “Achieving the top Euro NCAP five-star rating is clear validation of its safety performance and will serve as strong momentum as Kia expands its PBV lineup across Europe.”
The Euro NCAP tests highlighted the strong performance of a number of the PV5’s ADAS features, specifically calling out the following:
- Demonstrated strong responsiveness in vehicle-to-vehicle scenarios
- Provides additional protection for pedestrians behind the vehicle
- Avoided collisions in most pedestrian and cyclist test cases
The Kia PV5 slots into familiar territory for US buyers, landing roughly in the same size class as the Ford Transit Connect or Ram ProMaster City, with ~180 cubic feet of interior cargo space available, which is plenty to make it attractive for last-mile delivery and trade work in tight urban markets.
Globally, the PV5 is offered with a number of battery options, including a smaller 43.3 kWh Lithium-Iron-Phosphate (LFP) pack, as well as larger Nickel-Cobalt-Manganese (NCM) packs at 51.5 kWh and 71.2 kWh. The longest-range versions are good for about 250 miles of estimated range – more than enough for Kia to make a case for it as a practical, city-focused alternative to much larger (and pricier) electric vans.
Larger vans, by the way, that may not have that 5 star Euro NCAP rating.
