THE ENERGY INDUSTRY TIMES - MAY 2026
2
The latest edition of the International
Energy Agency’s (IEA) ‘Global En-
ergy Review’ revealed energy de-
mand grew at a slower pace in 2025
than the year before, but electricity
consumption continued to rise much
faster than overall demand – with so-
lar PV becoming the largest contrib-
utor to growth in global energy supply
for the rst time.
The report shows that overall global
energy demand growth slowed to 1.3
per cent in 2025, slightly below the
previous decade’s average of 1.4 per
cent and signicantly lower than in
2024. The main reasons for this slow-
down were lower global economic
growth, less extreme temperatures in
some regions, and rapid uptake of
more efcient technologies.
At the same time, global electricity
demand increased by around 3 per
cent – well over twice the rate of over-
all energy demand growth. Although
electricity demand growth was slow-
er than in 2024, reecting factors such
as lower cooling demand in India and
Southeast Asia amid less severe heat-
waves, it remained above the average
of the past decade. Electricity demand
growth was driven by multiple sectors
across buildings and industry – and
boosted by fast-growing demand
coming from electric vehicles and
data centres.
All major fuels and technologies
expanded to meet rising demand, but
at very different rates. Solar PV was
the single largest contributor to
growth in global energy supply in
2025, accounting for more than 25 per
cent of the increase – the rst time on
record that a modern renewable
source has led global primary energy
supply growth. Natural gas took the
next largest share, at 17 per cent, re-
ecting its role in power generation
in many countries. Overall, renewable
sources and nuclear met nearly 60 per
cent of all growth in energy demand
– and power generation from these
sources exceeded total growth in elec-
tricity demand.
“Global energy demand continued
to increase in 2025 against a complex
economic and geopolitical backdrop,
with one trend unmistakeable: the
expanding electrication of econo-
mies,” said IEA Executive Director
Fatih Birol. “Electricity consumption
is growing much faster than overall
energy demand – and one energy
source is growing much faster than
any other. Solar PV accounted for over
a quarter of all of the world’s energy
demand growth – more than any oth-
er source, for the rst time – followed
right after by natural gas. In today’s
rapidly shifting landscape, countries
that prioritise resilience and diversi-
cation will be best placed to manage
volatility and deliver secure and af-
fordable energy in the years ahead.”
In the electricity sector, the addition-
al 600 TWh of solar PV generation
worldwide in 2025 marked the largest
structural increase ever recorded in a
single year for any electricity gener-
ation technology, contributing to a
decline in coal red electricity gener-
ation globally. Battery storage was the
fastest growing power sector technol-
ogy in 2025. The roughly 110 GW of
new battery storage capacity added
during the year exceeded the largest
ever annual capacity additions for
natural gas. Meanwhile over 12 GW
of nuclear power reactors began con-
struction in 2025, amid renewed mo-
mentum for nuclear projects in sever-
al regions.
New gures by independent think-
tank Ember revealed global clean
power output grew faster than elec-
tricity demand last year. Ember also
noted that the rapid growth of solar
power in particular contributed to a
small annual decrease in output from
fossil fuel power stations.
It marked the rst time fossil fuel
output had fallen since the 2020 pan-
demic year, Ember said. Renewable
energy sources also generated more
electricity than coal red power sta-
tions in 2025, Ember said, “for the
rst time in the modern power sys-
tem”, extending a trend rst seen in
the rst half of last year.
ensuring among others, electricity
is taxed less than fossil fuels.
It said temporary measures would
be timely and targeted. Protecting
consumers, including industry,
from price peaks can include target-
ed income support schemes, energy
vouchers and social leasing
schemes, lowering excise duties on
electricity for vulnerable house-
holds. The Commission will also
adopt a State Aid Temporary Frame-
work, which will provide addition-
al exibility for national govern-
ments, including emergency
measures to support the most ex-
posed economic sectors.
Boosting investments will also be
a priority. Signicant resources are
available at EU level, such as those
under the Recovery and Resilience
Facility (‘RRF’: €219 billion) and
cohesion policy funds. In the current
crisis, “speed and impact are para-
mount”, said the Commission,
which will assist member states to
make maximum use of available EU
funding. However, public money
alone will not cover the signicant
investment needs (€660 billion a
year until 2030) for the energy tran-
sition. To mobilise private invest-
ments, the Commission therefore
adopted a Clean Energy Investment
Strategy in March 2026. The Com-
mission will organise a Clean Ener-
gy Investment Summit bringing
together the nancial services in-
dustry, including major institution-
al investors, industrial leaders, proj-
ect developers and public nanciers
to accelerate private nancing.
The EU’s climate commissioner
Wopke Hoekstra warned, however,
that there is no nancial “work-
around” for “mind-boggling” ener-
gy price rises in Europe. Hoekstra
said: “The only way forward is more
electrication, more nuclear, more
solar, more wind, more battery ca-
pacity, more interconnectors in the
European Union, and all of it with
much more speed.”
Following the publication of the
AccelerateEU strategy, the Boards
of Directors of the European Invest-
ment Bank (EIB) Group approved
a total of €10 billion in nancing,
including almost €2 billion for ini-
tiatives to expand Europe’s clean
energy investments, ensure afford-
ability and bolster competitiveness.
The new nancing supports EU
policy priorities and the European
Commission’s “Clean Energy In-
vestment Strategy” from March
2026 as well as the AccelerateEU
plan. Under both initiatives, the EIB
Group will work with the Commis-
sion to fast-track Europe’s switch
from fossil fuels to clean energy.
The Board of the EIB endorsed
loans to support the production of
offshore wind power in Germany
and solar energy in Italy as well as
the accelerated use of renewables
by businesses in Austria. The -
nancing also backs improvements
in energy savings in heating systems
in Latvia and Dutch grid upgrades
that increase capacity for renew-
ables and expand charging possibil-
ities for electric vehicles.
Commenting on Europe’s depen-
dency on imported fossil fuels,
which has now been highlighted for
the second time in less than ve
years, EIB Group President Nadia
Calviño, said: “There is one clear
lesson from Russia’s invasion of
Ukraine and the conict in the Mid-
dle East: Europe needs to break free
from its fossil fuel dependence.”
“The investments approved today
conrm the commitment of the EIB
Group to deliver on the energy tran-
sition and strengthen Europe’s stra-
tegic autonomy.”

Wind and solar power have grown
faster than almost anyone predicted
but projecting their future expansion
remains surprisingly difcult, nd
researchers at Chalmers University of
Technology, Sweden.
Researchers at the University have
developed what they call a computa-
tional “time machine” – a model that
outperforms existing projection
methods by using AI techniques to
analyse historical growth patterns
across countries.
Their central projection shows that
onshore wind is likely to supply
around 25 per cent of global electric-
ity by 2050, with solar reaching about
20 per cent. This is consistent with the
2°C target, but falls short of what is
required for 1.5°C.
Predicting the future is particularly
challenging for technologies like
wind and solar, where rapid cost de-
clines are offset by growing barriers
such as public opposition, infrastruc-
ture constraints and policy shifts.
“Existing models are very good at
identifying what needs to happen to
reach climate targets, but they can’t
tell us which developments are most
likely. That’s the gap we wanted to
ll,” said Jessica Jewell, Professor at
Chalmers University of Technology.
Across more than 200 countries, the
researchers identied a recurring pat-
tern in how wind and solar power
grow: long periods of relatively
steady expansion punctuated by sud-
den growth spurts often triggered by
policy shifts.
“Most models assume a smooth
S-shaped growth curve, but that’s not
how it actually looks in the real world.
Growth often comes in bursts, and if
you ignore that, you can misjudge how
fast technologies will expand,” said
Avi Jakhmola, a PhD Student at
Chalmers University of Technology
and rst author of the paper published
in Nature Energy.
With the goal of improving on cur-
rent predictions, Jakhmola created a
model built on 13 000 virtual worlds.
In each of these worlds, solar and
wind power develop in different ways
– from the fastest possible expansion
to the slowest – and everything in
between.
A machine learning algorithm was
then trained on all these worlds to
learn to predict global outcomes from
early national trends.
“When we apply the model to real-
world data, it can tell us what is the
most probable outcome for the future
– given what we have seen so far and
given all the virtual worlds it has
seen”, said Jakhmola.
By 2050, the model projects onshore
wind reaching around 26 per cent of
global electricity (central range: 20-
34 per cent), and solar around 21 per
cent (15-29 per cent). This broadly
aligns with 2°C-compatible pathways
but falls short of what’s needed for
1.5°C.
Professor Jewell said: “It’s long
been a joke how bad technology fore-
casts are. But if you’re a decision
maker, trying to gure out how hard
to push for change, you need a realis-
tic baseline. Our study is the rst step
towards developing such a realistic
view of the future.”
As countries prioritise energy security,
energy demand will be increasingly
met through electrication, renew-
ables, coal and nuclear, while reliance
on globally traded fuels declines, ac-
cording to Wood Mackenzie. Howev-
er, this shift comes with trade-offs.
Under its new conict scenario –
part of its ‘Lens Energy Transition
Scenarios’, which explores how sus-
tained geopolitical instability could
reshape global energy demand, sup-
ply and investment through 2050 –
Wood Mackenzie predicts energy
systems will become more domestic
and diversied, but also more costly,
while near-term emissions rise due to
increased coal use before converging
with the base case over the longer
term.
The scenario assumes a major geo-
political escalation beginning in early
2026, disrupting 15-20 per cent of
global oil and LNG supply. In the near
term, oil demand falls by around 9 per
cent due to supply outages before re-
covering to pre-crisis levels by 2030,
Wood Mackenzie noted.
Beyond 2030, structural shifts take
hold as countries accelerate efforts to
reduce reliance on imported fuels. Oil
and gas demand declines more rapid-
ly than in the base case, as govern-
ments prioritise domestic and diver
-
sied energy systems.
The shift towards energy indepen-
dence comes with higher system costs,
as countries move away from globally
optimised supply chains towards do-
mestic production and diversied
sourcing, says Wood Mackenzie.
“Energy independence reduces ex-
posure to external shocks, but it comes
at a structural cost premium,” said
Lindsey Entwistle, Principal Analyst,
Scenarios & Technologies. “This cre-
ates new competitiveness challenges
for energy-intensive industries, while
advantaging more self-sufcient
regions.”
Jom Madan, Principal Analyst, Sce-
narios & Technologies, noted: “Ener-
gy systems become more local, more
diversied and less reliant on complex
international trade.
“Electrication and nuclear take
priority, while hydrogen and carbon
capture are de-prioritised due to cost,
efciency and security consider-
ations,” he added.
