Renewables by 2030: Tripling installed capacity becomes a global priority

The growth of renewable energy is returning to the forefront of international debate as a key lever for curbing global warming and accelerating the transition away from fossil fuels. This is no longer simply a technological or industrial trajectory, but a shift increasingly tied to states' climate responsibility and their ability to translate international commitments into concrete measures.

On 20 May 2026, the United Nations General Assembly passed a resolution calling on States to implement measures consistent with the objective of limiting global warming to 1.5°C, including by tripling renewable capacity and doubling the global average annual rate of improvement in energy efficiency by 2030. The text also calls for the gradual phase-out of fossil fuels in energy systems, in a just, orderly and equitable manner, with the aim of achieving net-zero emissions by 2050.

Renewables and energy efficiency as pillars of the transition

The call to triple renewables and double energy efficiency improvements confirms a direction that is now central to the global transition . Decarbonization cannot depend on a single intervention, but requires a coordinated transformation of energy systems, buildings, industrial consumption, and infrastructure.

For the HVAC and energy sectors, this transition is particularly significant. The growth of renewables must proceed alongside the electrification of consumption, the deployment of high-efficiency systems, and the reduction of overall energy demand . Heat pumps, building automation, storage systems, smart grids, and advanced load management are becoming operational tools to make the integration of clean sources more effective.

The transition therefore requires interventions on multiple levels:

• new capacity from renewable sources , particularly solar and wind;
• reduction of consumption through energy efficiency;
• electrification of thermal and production consumption ;
• storage and network flexibility to manage production variability;
• progressive reduction in the use of fossil fuels ;
• elimination of inefficient subsidies to fossil fuels , when not linked to the protection of energy poverty or just transitions.

The key is to move from objectives to operational conditions: faster authorizations, investments in networks, adequate financing tools, and technical expertise spread throughout the supply chain.

States' climate responsibility and the role of energy policies

The resolution builds on the process initiated by the International Court of Justice's advisory opinion on the legal responsibility of states with respect to climate change. The principle highlighted is clear: governments are required to act to protect the climate system , and failure to adopt adequate measures may also be relevant under international law.

This strengthens the link between climate policies, energy planning, and industrial choices. Production, consumption, and support for fossil fuels are no longer evaluated solely in economic or geopolitical terms, but also in terms of environmental impacts and the protection obligations of present and future generations.

The General Assembly vote revealed broad consensus , but also divergent positions among countries. The European Union confirmed its support for the goal of tripling renewable capacity by 2030 and doubling annual energy efficiency improvements, linking these commitments to climate neutrality by 2050 and intermediate emissions reduction targets.

From the global picture to buildings: what's changing for the HVAC supply chain?

For HVAC professionals, international renewable energy targets are not far from their daily work. The decarbonization of energy systems also involves buildings, where heating, cooling, ventilation, and domestic hot water production are key areas for reducing consumption and emissions.

Increasing renewable energy production can generate tangible benefits only if accompanied by more efficient buildings and systems capable of intelligently using clean energy. This means designing integrated systems where building envelope, climate control, regulation, storage, and local renewable energy generation work together.

The challenge , therefore, is not just how much renewable energy will be installed by 2030, but also how this energy will be used . To transform the tripling of renewables into a real climate and economic advantage, it will be necessary to reduce consumption, increase plant efficiency, and accelerate the deployment of high-performance electrical solutions.

The international direction is clear: renewables and efficiency are no longer complementary options, but essential pillars of a credible energy transition. For the energy and plant supply chain, this means strengthening skills, design capabilities, and operational tools to concretely contribute to the climate goals of the coming years.
