Sweden, Australia, Netherlands, Germany and Denmark are the leading countries for per capita solar and wind generation capacity, according to data by the International Solar Energy Society (ISES).

Furthermore, it explains that global solar capacity has been doubling every 3 years, and wind every 6 years, whereas fossil and nuclear capacity and generation have been almost static in recent years.

[...]

Combined global per capita solar and wind capacity is more than double hydro capacity, and seven times larger than nuclear capacity.

[...]

The leading countries for speed of deployment of solar and wind (new Watts per person per year averaged over 2022-24) are Lithuania, Finland, Estonia, Sweden, Netherlands, Australia and Austria (Figure 2). Most of the leading countries are in Europe, along with Australia, Qatar, China and Chile.

[...]

Solar PV capacity has been growing faster than all other electricity generation technologies combined since 2022. Since 2010, when it started publishing the World Energy Outlook, the International Energy Agency has vastly underestimated the growth of solar and other renewable energy technologies.

While photovoltaics (PV) play an increasingly central role in Europe’s clean energy transition and energy independence, a hidden vulnerability threatens this progress: the software-based remote access to inverters, the critical “brains” of any PV system.

“Today, over 200 GW of European PV capacity is already linked to inverters manufactured in China – the equivalent of more than 200 nuclear power plants,” said Christoph Podewils, the European Solar Manufacturing Council (ESMC) Secretary General.

“This means Europe has effectively surrendered remote control of a vast portion of its electricity infrastructure.”

[...]

Further concerns include:

  • 70% of all inverters installed in 2023 came from Chinese vendors, mainly Huawei and SunGrow.
  • These two companies alone already control remote access to 168 GW of PV capacity in Europe (DNV Report, p. 40), by 2030, this figure is projected to exceed 400 GW – comparable to the output of 150–200 nuclear power plants.
  • One of these vendors [China's Huawei] is already banned from the 5G sector in many countries and is currently under investigation in Belgium for bribery and corruption.

[...]

In light of these findings, the ESMC calls for the immediate development of an EU “Inverter Security Toolbox”, modeled after the successful 5G Security Toolbox. This would involve:

  • A comprehensive risk assessment of inverter manufacturers.
  • A requirement that high-risk vendors must not be permitted to maintain an online connection to European electricity systems.
  • Consideration of outright bans for such vendors from connecting to the grid.
  • A replication of Lithuania’s proactive legislation – banning inverters from China – across all EU Member States – ensuring security measures apply to PV systems of all sizes.

US energy officials have found unexplained communication equipment inside some Chinese-made inverter devices.

[...]

Reuters reported the presence of undocumented and “rogue” communication devices in a number of Chinese-made solar inverters. These could potentially introduce unregulated and undocumented remote communication channels to the inverters, by which an actor could remotely bypass the cybersecurity firewalls that utility companies use to prevent direct communication back to China.

SolarPower Europe has removed Chinese tech giant Huawei as a member, marking the first time the Brussels-based solar industry association has taken such action, an SPE spokesperson has told pv magazine. The board made the decision on April 28, 2025, and “the procedure is continuing as laid out in our statutes,” said the spokesperson.

[...]

The move follows the European Commission’s recent decision to cut off contact with trade associations representing Huawei’s interests, citing an ongoing corruption investigation.

“The decision comes in the context of the European Commission’s decision to restrict meetings with associations who have Huawei in their membership,” said the SPE spokesperson in an email.

[...]

Several other EU industry groups, including DigitalEurope and BusinessEurope, have also moved to suspend Huawei in recent weeks.

Solar panels with suspected links to Chinese slave labour have been installed by dozens of organisations including Manchester City, Cheltenham Racecourse and David Lloyd gyms, The i Paper can reveal.

The scale of Britain’s use of solar panels made by firms alleged to have used components made from the forced labour of minorities in China can be disclosed for the first time.

As well as commercial premises, the locations include schools, hospitals and universities across the country. There is no suggestion that any of the organisations installed solar panels with knowledge of links to Chinese slave labour.

...

[The investigation] has mapped 84 non-residential locations where solar panels have been installed with links to alleged slave labour. The data is based on evidence provided by Sheffield Hallam University’s Helena Kennedy Centre for International Justice, the Inter-Parliamentary Alliance on China (IPAC) and open source analysis.

...

Last week, growing concerns over Britain’s use of Chinese panels with links to Uyghur oppression forced [UK] Energy Secretary Ed Miliband into banning them from being used by the state-funded Great British Energy company unless it can “ensure that slavery and human trafficking is not taking place” in its business or supply chains.

...

IPAC’s senior analyst Chung Ching Kwong believes [the] disclosures are a conservative estimate of the UK’s use of such tainted technology, because of the lack of transparency about the original source of materials used in many panels.

UK consumers are unknowingly complicit in Uyghur forced labour,” said Ms Kwong. “Our work shows how big a mountain the government has to climb to root out slave-made renewables.”

...

Professor Laura Murphy at the Helena Kennedy Centre for International Justice at Sheffield Hallam University has led the way in tracing the original source of polysilicon in these panels. Her latest report in 2023 detailed how a number of Chinese firms had “high” exposure to production in Xinjiang. As well as Jinko, these included: JA Solar, Qcells, Canadian Solar, Trina Solar, and LONGi Solar.

Her report stated: “None of the companies that were engaged in state-sponsored labour transfers in 2021 has announced any changes to its recruitment methods or shown any resistance to participation in the PRC (Peoples Republic of China) Government’s programmes. Indeed, since that time, the PRC Government’s labour transfer programme has only increased in scale and the pressure on companies to absorb the workers the state deemed to be surplus remains high.”

...

The UK formed the Solar Stewardship Initiative (SSI) with trade organisations in a bid to tackle human rights challenges within the global solar supply chain including “rigorously” auditing some Chinese sites. Trini Solar and JA Solar are members. The latter firm was suspended in January after the US banned panels made by one of its subsidiaries but was reinstated after the SSI concluded its supply practices had changed.

SSI’s chief executive Rachel Owens said: “We are acutely aware of the complexities involved in verifying supply chain links that may be several tiers removed from the end-product. That is precisely why the SSI, together with a large range of stakeholders including civil society, human rights experts, international financial institutions and industry, developed the SSI Supply Chain Traceability Standard. It will be implemented in 2025.”

...

Some Chinese firms have criticised Sheffield Hallam’s report, claiming it disregards corporate due diligence policies.

But Prof Murphy who strongly defended her research, warned against companies taking the words of Chinese firms as evidence that supply chains are clean.

She said: “A simple attestation that forced labor has been excluded simply isn’t enough to ensure that modules are in fact free and clear of forced labor.”

Chloe Cranston at Anti-Slavery International, claimed a lack of extensive testing of Chinese manufacturers has made the UK a “dumping ground” for panels linked to slave labour.

She said: “What we were seeing is many of the big solar companies… essentially creating one clean supply chain for the US to meet the requirements there but then they were not having to take those same steps in other markets globally meaning that the UK market was opening itself up as a dumping ground.”

Here is the original study: Restrict Remote Access of PV Inverters from High-Risk Vendors

The European Solar Manufacturing Council (ESMC) has issued a stark warning, highlighting a critical threat to Europe’s energy autonomy stemming from the unregulated remote access capabilities of PV inverters produced by non-European, high-risk manufacturers—particularly those from China. A recent study by DNV substantiates these concerns.

As solar power becomes increasingly integral to Europe’s clean energy goals and energy security, a major vulnerability looms: software-enabled remote access to PV inverters—the essential control units of solar power systems.

[...]

The threat is real, not hypothetical. Internet connectivity is essential for modern inverters to perform grid support functions and participate in power markets. However, this connectivity also enables remote software updates, allowing manufacturers to potentially modify device performance from afar. This poses serious cybersecurity risks, including the danger of intentional disruption or large-scale shutdowns. A recent DNV report, commissioned by SolarPower Europe, highlights the credible risk of cascading blackouts due to coordinated or malicious manipulation of inverters.

Ancient practices hold important lessons for farmers facing drying lands, but they were often more complex than modern societies realize. Glacier loss adds to the challenge today.

Ancient beliefs, behaviors and norms – what archaeologists call culture – were fundamentally integrated into technological solutions in this part of Peru in ancient times. Isolating and removing the tools from that knowledge made them less effective.

The pursuit of net zero has relied on Uighur Muslims forced to work in appalling conditions. Experts say Britain should follow other countries and take tougher stance.

...

Many of the Chinese workers who are helping us to go green do not want to be at those factories. They do not arrive at work to manually crush silicon and load it into blazing furnaces because of a love of renewables, much less to earn a decent wage.

They are there as part of a mass forced labour programme by the Chinese Communist Party (CCP) that critics describe as a genocide. A reliance on men and women from the Uighur Muslim minority living in detention centres has helped the Xinjiang region to become the epicentre of the solar industry over the last 15 years.

At its peak, analysts believe that 95 per cent of the world’s solar modules were potentially tainted by forced labour in the region [of Xinjiang, in northwestern China]. This reliance on products partly made through working conditions that would be unfathomable in modern Britain represents what the Conservative MP Alicia Kearns calls an ethical “blind spot”.

...

It is not only solar panels that are linked to widespread human rights abuses in the so-called Xinjiang Uighur autonomous region. Fuelled by an abundance of cheap, coal-driven electricity, the region produces vast amounts of everything from cotton to the lithium batteries that are ever more essential to our tech-driven lives.

But as governments across the world invest in solar energy in the race to reach net zero, experts have described a critical opportunity to curtail what has been one of Xinjiang’s champion industries.

...

Alan Crawford, a chemical engineer who authored a 2023 report that exposed several companies with ties to forced labour, said that transparency from Chinese producers had decreased as a result. “Transparency has gotten worse because the Chinese know that people like us are looking,” he said.

While the Chinese authorities maintain that the Uighur community is free, images of internment camps have shown razor-wire fences manned by police. Leaked police files revealed a shoot-to-kill policy for escapers.

...

The pervasiveness of forced labour across the early stages of the production process makes it difficult to find polysilicon from Xinjiang that has not been contaminated by forced labour. Hoshine Silicon, the dominant MGS producer in Xinjiang and a major supplier to the region’s polysilicon producers, has engaged in “surplus labour” programmes at its factories.

One propaganda account from 2018 details how a married couple were engaged in a “poverty alleviation” scheme in which they were moved 30 miles from their home in the rural Dikan township to work at a Hoshine factory in Shanshan county, leaving behind their children. The couple were described as being “relieved” of their worries by transferring their seven-acre grape farm to the state.

...

[Laura] Murphy, a senior associate at the Centre for Strategic and International Studies, said legislation introduced in the US in 2021 showed how supply chains can be cleaned up. The Uighur Forced Labour Prevention Act, which bans the import of goods linked to the region, has led to thousands of solar panel shipments being stopped by US customs.

...

It is for this reason that Murphy believes the UK should mirror the US approach, a strategy already being pursued by the European Union. If the UK’s controls against forced labour are not robust, there is a high probability that the UK will simply become a “dumping ground” for the tainted goods not wanted by the US.

...

Andrew Yeh, executive director of the China Strategic Risks Institute, said relying too heavily on China for solar energy products could also leave Britain vulnerable in a geopolitical crisis.

...

For Murphy, legislation is the only meaningful response to the issue. [...] She said: “Whatever it is that other countries think they might be doing to discourage it, shy of legislation, shy of enforcement, it is not working.

“We can be morally outraged all we want and we can express our desires not to have forced labour-made goods, even at governmental level. But until we actually put it in law and enforce it, companies will continue to import goods made with forced labour into the UK.”

I am doing some review for farm robotics and I stumbled upon that project, which I thought was pretty cool. I have met the people who are doing it 6 years ago, when they described themselves as "hippies working off the sustainability budget of Sony Research" and looks like now they manage to live off public European funding and open sourced their designs.
