OECD nations have reached a deni-
tive turning point, transitioning from a
historical peak in fossil fuel generation
to a sustained and structural decline,
according to recent report from UK-
based energy think-tank Ember.
Ember’s ‘Global Electricity Re-
view’ showed that record solar growth
meant clean power sources grew fast
enough to meet all new electricity
demand in 2025, thereby preventing
an increase in fossil generation, which
saw a small fall of 0.2 per cent. This
was the rst year since 2020 without
an increase in electricity generation
from fossil fuels and only the fth year
without a rise this century.
The analysis further shows OECD
fossil generation in 2025 was 19 per
cent below its peak. Since peaking in
2007, fossil fuel generation in OECD
has dropped 19 per cent (-1313 TWh),
lowering its share in the mix from 63
per cent to 48 per cent by 2025. This
shift resulted in a 28 per cent reduction
(-1477 MtCO2e) in OECD power
sector emissions. The rise in solar and
wind generation in this period (+2138
TWh) met both the fall in fossil gen-
eration (+1313 TWh) and also the rise
in electricity demand (+630 TWh) in
their entirety.
Every OECD country in 2025 was
below its fossil generation peak for
the rst time. Nearly all, 36 out of the
38, OECD countries saw fossil gen-
eration peak in 2019 or before. Tür-
kiye peaked in 2021, and Colombia
peaked in 2024. Two member states
– Iceland and Costa Rica – now oper-
ate zero-emission power systems, a
further seven maintain fossil share
below 10 per cent, while a group of
six nations remains heavily reliant on
fossil fuels for over 60 per cent of their
electricity generation.
Non-OECD fossil generation fell in
2025 as China peaks and India avoids
coal reliance.
Beyond the OECD, 2025 also
marked the rst year this century, out-
side the COVID affected 2020, in
which non-OECD fossil generation
fell, as China (-0.9 per cent) and India
(-3.3 per cent) both fell. China’s fossil
output declined as solar expanded
rapidly. India, meanwhile, is moving
towards clean energy without repli-
cating the coal heavy trajectory of
earlier industrialising economies.
The report said ambitious coal
phase-out targets, combined with rap-
id wind and solar deployment, have
allowed OECD nations to increasing-
ly decouple their electricity sectors
from fossil fuels in favour of a clean-
er power mix.
“For governments, this shift rep-
resents a strategic pivot toward ener-
gy sovereignty; by prioritising do-
mestically generated renewables,
countries are insulating themselves
from the price volatility and geopolit-
ical risks that accompany dependence
on global fossil fuel markets,” the
report stated.
The ndings came as the Interna-
tional Renewable Energy Agency
(IRENA) published a report showing
that the economics of solar and wind
energy paired with battery storage in
prime solar and wind regions deliver
round-the-clock power at lower costs
than fossil fuels.
Firm levelised costs of electricity
(‘rm costs’) for solar plus storage
range from $54-82/MWh in high-
quality resource regions, compared
with $70-85/MWh for new coal in
China and more than $100/MWh for
new gas globally.
Commenting on the report, IRENA
Director-General Francesco La Cam-
era said: “24/7 renewable power is
now cost-competitive with fossil fu-
els. The long-standing argument that
renewables lack reliability no longer
holds. Today, renewables can deliver
reliable, round-the-clock power. As
oil and gas markets remain exposed
to geopolitical shocks, including on-
going disruptions in the Strait of Hor-
muz, we must insulate our economies
with resilient renewable systems.”
Commission failed to provide “any
specic facts or technical evidence”
to back its decision.
“This restriction lacks an objective
and transparent basis, constitutes
origin-based discrimination, and
violates the principle of fair and
non-discriminatory treatment in
international trade... All suppliers
should be held to the same standards
of technical transparency and cyber
security,” Huawei said.
A report issued in late April by
Loom, a non-prot organisation
focused on economic, environmen-
tal and national security issues, said
dependence on Chinese green tech-
nology was making European coun-
tries vulnerable to cyber attacks,
trade restrictions and espionage.
The report co-authored by Mi-
chael Collins, a former deputy head
of national security strategy in the
UK Cabinet Ofce, said European
governments were failing to fully
account for such risks as they roll
out Chinese green tech in a bid to
secure energy supplies and address
climate change.
Collins told the Financial Times
that countries risked “sleepwalking
into a scenario where you’re sud-
denly confronted with a big nation-
al security problem”.
The report, co-authored by Mi-
chal Meidan, Director of the China
Energy Programme at the Oxford
Institute for Energy Studies and
based on interviews with energy
and national security experts, iden-
tied eight separate risks linked to
an over-reliance on Chinese green
technology.
Among the greatest was supply
chain disruption, according to the
authors, who argued that China was
likely to restrict supply of low-car-
bon technology and components.
Asked about the report, the foreign
ministry in Beijing said the essence
of China-EU trade relations was
“mutual benet and win-win out-
comes” and should not be “politi-
cised or subjected to an overly broad
security framing”.
Chinese ofcials dismissed con-
cerns about dependence on their
country’s green technology, say-
ing that Beijing has no intention
of using it for political advantage
and that cheap turbines, solar pan-
els and other renewable energy
products reduce the much greater
risk stemming from high carbon
emissions.
Loom’s Executive Director, Joss
Garman, said the recent fossil fuel
price shocks “should accelerate Eu-
rope’s energy transition but new
dangers arise because the cheapest
route runs so overwhelmingly
through China”.
Meanwhile, in late April, Chinese
wind turbine maker Ming Yang
Smart Energy accused the UK of
“politicisation” after the UK gov-
ernment ruled in March that Ming
Yan g cou ld no t dep lo y i ts p roduct s
in offshore projects in the country,
and rejected plans to invest £1.5
billion in manufacturing turbine
blades and other parts in the Scottish
Highlands.
Ming Yang’s Chair, Zhang Chuan-
wei, said in an interview with the
FT that the UK’s “politicisation” of
the investment would not only harm
Ming Yang but also “greatly under-
mine the sense of security Chinese
companies feel when entering the
British market”.
He said that he and other Ming
Yan g executi ves had spo ke n to th e
UK’s energy ministry, but the gov-
ernment declined to explain what
made its products a national securi-
ty threat.

New research led by the University of
Oxford and University College Lon-
don (UCL), UK, has revealed that pol-
lution from coal red power plants is
signicantly reducing the energy out-
put of solar photovoltaic (solar PV)
installations, particularly where these
are expanding side-by-side.
The ndings, published in Nature
Sustainability, map and assess more
than 140 000 solar PV installations
worldwide using satellite data. By
combining this with atmospheric data
on air pollution, the researchers cal-
culated how much sunlight is lost and
how this reduces electricity genera-
tion. They found that aerosols – tiny
particles suspended in the air – re-
duced global solar electricity output
by 5.8 per cent in 2023. This is equiv-
alent to 111 TWh of lost energy – the
amount generated by 18 medium-
sized coal red power plants.
Crucially, these losses represent a
signicant and often overlooked
constraint on the clean energy transi-
tion. Between 2017 and 2023, new PV
installations added an average of
246.6 TWh of electricity each year,
while aerosol-related losses from ex-
isting systems reached 74.0 TWh an-
nually – equivalent to nearly one-third
of the gains from new capacity. This
highlights a previously unrecognised
interaction between fossil fuel use and
renewable energy, where emissions
from one system directly reduce the
performance of the other.
Lead author Dr Rui Song (Depart-
ment of Physics, University of Ox-
ford, and Mullard Space Science Lab-
oratory, UCL) said: “We are seeing
rapid global expansion of renewable
energy, but the effectiveness of that
transition is lower than often assumed.
As coal and solar expand in parallel,
emissions alter the radiation environ-
ment, directly undermining the per-
formance of solar generation.”
To identify the sources of these
aerosol-related losses, researchers
traced their origins and found coal
red power generation to be a major
contributor. This effect is particularly
evident in China, where solar and coal
capacity have expanded in parallel and
are often co-located. Regions with
high coal capacity aligned closely
with areas experiencing the greatest
solar PV losses.
China is the world’s largest solar
producer, and generated 793.5 TWh
of solar PV electricity in 2023 (41.5
per cent of the global total). But it also
experienced the largest losses from
aerosols, with total output reduced by
7.7 per cent. The researchers estimate
that around 29 per cent of aerosol-re-
lated solar PV losses in China come
specically from coal red power
plants. Coal plants emit ne pollution
particles that scatter and absorb sun-
light, reducing the amount that reach-
es nearby solar panels. As a result, the
panels generate less electricity than
they otherwise could.
Interestingly, China was also found
to be the only major region showing
a sustained improvement. Aerosol-re-
lated solar PV losses declined by an
average of 0.96 TWh per year (-1.4
per cent annually) between 2013 and
2023. This is likely due to stricter
emission standards and widespread
adoption of ultra-low-emission tech-
nologies within coal red power
plants, rather than a reduction in coal
capacity itself.
Co-author Dr Chenchen Huang
(University of Bath) said: “Our nd-
ings send a clear warning to the Sus-
tainable Development Goals: over-
looking pollution-induced solar
energy losses can lead to a systematic
overestimation of renewable energy
output by governments, businesses
and the broader community. To stay
on track, policies must account for this
hidden drag and shift fossil-fuel sub-
sidies away from coal.”
The Global Renewables Alliance
(GRA) has announced its 2026 corpo-
rate partners, bringing together leading
companies from across the renewable
energy value chain at a critical moment
for the global energy transition. As
countries and businesses face contin-
ued energy insecurity, price volatility
and growing pressure on competitive-
ness, the partnership underlines the
urgent need to accelerate the deploy-
ment of renewable power, grids and
storage.
This year’s partners include Fortes-
cue, Iberdrola, Arup, EDP, Hitachi,
Octopus Energy Generation, Ørsted,
SSE, SUNOTEC, and Vestas.
Together, these companies represent
a broad cross-section of the global
energy ecosystem, including develop-
ers, utilities, technology providers,
manufacturers, investors, advisors,
and major energy buyers. By partner-
ing with GRA, they contribute indus-
try expertise and strengthen the pri-
vate sector voice in support of tripling
global renewable energy capacity by
2030.
“Energy has become a dening issue
for economic stability and competi-
tiveness,” said Bruce Douglas, CEO
of the Global Renewables Alliance.
“The companies partnering with GRA
this year are demonstrating that re-
newables, combined with grids, stor-
age and electrication, are not only
the fastest and cheapest route to de-
carbonisation, but the foundation of a
secure and resilient energy system.
Turning ambition into implementa-
tion is now the priority.”
Across industries, partners high-
lighted the growing role of renew-
ables in addressing today’s energy
challenges.
Andrew Forrest, Executive Chair-
man and Founder at Fortescue, said:
“Volatile fossil fuel prices are a hand-
brake on global growth. Nations and
industries cannot build prosperity on
fuels that swing wildly in cost and
security. The only real pathway for-
ward is clear – replace fossil fuels with
abundant, predictable renewable en-
ergy. Fortescue is proving that heavy
industry can be decarbonised now, not
decades from now.”
Gonzalo Sáenz de Miera, Director
of Climate Change and Alliances at
Iberdrola, said: “Electrication is at
the heart of the response to today’s
security and competitiveness chal-
lenges, stemming from the continued
dependence of our energy model on
fossil fuels… Through our partner-
ship with the Global Renewables Al-
liance, we are joining forces with key
partners to accelerate electrication
worldwide and deliver meaningful
benets across society.”
Through their partnership with
GRA, the companies will share prac-
tical business experience and demon-
strate how renewable energy is al-
ready delivering tangible benets for
businesses and economies.
