Climate Challenges and Global Energy Strategies: Between Urgency and Complexity

Key Points

Extreme climatic phenomena, such as heatwaves and droughts, are intensifying, leading to significant economic and environmental impacts globally.
Energy strategies are diversifying, with massive investments in renewable energies and nuclear power, but also challenges related to costs and technological integration.
The energy transition is marked by tensions between acceleration towards decarbonized solutions and the persistence of dependence on fossil fuels in certain regions.
Innovations such as agrivoltaics and solar complexes with storage are emerging, while decarbonization efforts are being undertaken by major industrial players.

The Climate Emergency and its Repercussions

Climate change is manifesting through an intensification of extreme weather phenomena, with direct consequences for economies and ecosystems. Europe, for example, is facing severe heatwaves, increasing demand for cooling systems and electricity . In France, an association has appealed to 44 prefects to request the suspension of summer hunting and the postponement of the general opening to September, due to a historic drought and heatwaves . The Minister of Agriculture and Food Sovereignty has warned of a “deep crisis” in French agriculture, directly attributable to the drought, heatwaves, and fires affecting all productions . Government measures have been announced for businesses affected by the fires, although deemed insufficient by some economic actors .

These climatic disruptions also have macroeconomic repercussions. Rising temperatures risk amplifying economic inequalities between countries by affecting agriculture, productivity, and investment . Extreme heatwaves could cut European GDP by 1%, with France being particularly vulnerable . Beyond direct impacts, the drainage of tropical peatlands, particularly for agriculture such as palm oil plantations, exposes enormous underground carbon reserves to oxygen, leading to microbial oxidation and significant emissions of greenhouse gases such as CO2, methane, and N2O . These emissions per hectare are higher than those resulting from the deforestation of the tropical forest that covered them .

Diversification of Energy Approaches

Faced with these challenges, global energy strategies are diversifying. Canada has announced an investment of 70 billion Canadian dollars in renewable energies, with the goal of doubling its electricity capacity by 2050 . In South America, a 510 MW solar and battery storage complex has been inaugurated in Chile's Atacama Desert, with a combined solar capacity of 692 MW .

Technological innovation plays a key role. Research in Italy has shown that agrivoltaic systems can reduce soil temperature by more than 20 °C, positively influencing microclimates and crops . However, the commercial success of certain advanced solar technologies, such as two-terminal perovskite-silicon tandem cells, will depend on geographical and market conditions rather than efficiency gains alone, due to external spectral variations that can lead to current mismatch . Despite growing demand for cooling solutions in Europe, solar module prices are falling .

Nuclear power remains an option for some countries. In France, the program to build six EPR2 nuclear reactors is marked by financial uncertainties, with construction costs already having jumped by 40% to reach 72.8 billion euros (in 2020 euros), not including borrowing interest . At the same time, regional interconnection projects aim to strengthen energy security, as in Cameroon where international tenders have been launched for the construction of 419.6 km of 225 KV high-voltage lines and electrical substations, to supply 100 MW of electricity to Chad .

Challenges of Transition and Controversies

The energy transition is complex and faces obstacles. In Germany, environmental organizations have filed a complaint in Brussels against an energy bill, believing it favors gas-fired power plants and fossil technologies . This situation illustrates the tensions between decarbonization objectives and the need to ensure stable energy supply.

Dependence on fossil fuels persists in certain regions. During the first seven months of 2026, vessels linked to a Greek shipowner transported 57 cargoes of liquefied natural gas (LNG) from a Russian project, representing 4.14 million tons and 35% of the volumes exported from this Arctic site to the European Union .

Nevertheless, significant efforts are being made for industrial decarbonization. A Chinese battery manufacturing company achieved carbon neutrality for its core operations by the end of 2025, positioning itself as the only TWh-scale battery manufacturer with carbon-neutral “core” operations. The company aims for carbon neutrality across its entire value chain by 2035 . The European Commission has also clarified that member states can finance projects aimed at energy resilience, including electric car charging and green renovations, without these expenditures impacting their compliance with budgetary rules .

The complexity of the energy transition lies in the need to reconcile climate urgency with economic and technological imperatives. The financial uncertainties of large nuclear projects, the geographical limits of certain solar innovations, and the debates surrounding national energy policies highlight that the path to a decarbonized economy is fraught with pitfalls and delicate strategic choices. The question remains how to accelerate this transition while ensuring global energy security and equity.
