BAKU, Azerbaijan, June 28. Global investment in
the energy sector is expected to reach a record $3.4 trillion in
2026, as governments and businesses increasingly prioritize energy
security.
This was reflected in the statement published by the Ministry of
Energy of Uzbekistan, showcasing an increase of 5% from the
previous year.
Nearly two-thirds of total investment, or about $2.2 trillion,
is projected to flow into clean energy technologies, including
renewable power generation, nuclear energy, electricity grids,
energy storage systems and electrification projects. Investment in
oil, natural gas and coal is expected to total approximately $1.2
trillion.
The global energy transition is no longer driven solely by
efforts to combat climate change. Growing geopolitical tensions,
including instability in the Middle East and risks to key energy
transit routes such as the Strait of Hormuz, are prompting
countries to strengthen domestic energy production and reduce
exposure to external supply disruptions.
"Solar energy is a $365 billion industry. Over the past decade,
the cost of deploying 1 GW of solar capacity has fallen from $3
billion to $700 million, and the volume of new installations has
increased tenfold. The highest growth in solar panel imports is
being observed in Africa and Southeast Asia." the ministry noted in
the statement.
Investment in wind power is forecast to reach $200 billion,
while hydropower projects are expected to receive $75 billion.
Nuclear energy is also experiencing renewed momentum, with
global investment projected at $80 billion. New nuclear facilities
with a combined capacity of 78 gigawatts are currently under
construction across 15 countries, while more than 40 nations have
adopted policies supporting the sector's development.
Electricity grids are expected to attract $550 billion in
investment, representing a 20% increase from previous levels, while
energy storage systems are projected to receive $100 billion.
Industry experts increasingly view grid infrastructure as one of
the most critical challenges facing the global energy
transition.
Investment in energy efficiency improvements is expected to
reach $350 billion.
Electricity-related sectors now account for approximately 60% of
global energy investment, reflecting the growing importance of
electrification across economies.
Demand from artificial intelligence applications and data
centers is emerging as a major driver of electricity consumption.
Investment in data center infrastructure alone reached $100 billion
in 2025, exceeding total energy-sector investment across the
African continent.
According to industry estimates, investments in renewable
energy, electrification and energy-efficiency technologies helped
major energy-importing countries reduce fuel import costs by
approximately $260 billion in 2025. China accounted for roughly
$110 billion of those savings.
As renewable generation expands, many countries are reducing
their dependence on imported fossil fuels, particularly natural
gas. Analysts say this shift is transforming the energy transition
from an environmental initiative into a broader economic and
strategic policy tool aimed at strengthening resilience against
geopolitical uncertainty and external supply shocks.
Analysis
The latest investment projections suggest that energy security
has become as important a driver of the global energy transition as
climate policy. While decarbonization remains a key objective,
recent geopolitical disruptions have highlighted the economic and
strategic risks associated with dependence on imported fuels.
The sharp increase in investment in electricity grids, storage
systems and domestic power generation reflects a growing
recognition that reliable energy supply is now a national security
issue. Countries are increasingly seeking to diversify energy
sources and reduce vulnerability to disruptions in global commodity
markets.
"The continued decline in renewable energy costs, particularly
in solar power, is accelerating this trend. Renewable technologies
are becoming not only cleaner alternatives but also economically
competitive sources of energy that can improve energy independence
and lower long-term costs." the Trend's analysis says.
The resurgence of nuclear energy is another notable development.
After years of relatively limited growth, many governments are
turning to nuclear power as a stable, low-carbon source of
electricity capable of supporting expanding power demand from
industry, electrification and artificial intelligence-related
infrastructure.
For emerging economies, the shift presents both opportunities
and challenges. Countries that invest in renewable generation,
modern grid infrastructure and energy efficiency could strengthen
energy security, reduce fuel import bills and improve industrial
competitiveness. However, financing requirements remain
substantial, particularly for large-scale transmission networks and
energy storage systems.
Overall, the data indicate that the global energy transition is
entering a new phase—one driven not only by environmental
considerations but also by economic resilience, technological
transformation and geopolitical realities.
