The last year has been particularly interesting in the energy sector. Despite the obstructionist policies promoted by leaders like Trump and others with similar interests, the energy transition has continued to advance. And it has done so not for ideological reasons, but for a much more powerful one: economics.
Today, there is no longer any serious debate about which energy source is the cheapest. Solar power has established itself as the lowest-cost option in practically the entire world. Even in the United States, where the political discourse is contradictory, 75% of the new generation capacity installed in the US in 2025 was solar. Competing against the cheapest option is unwise and, in the long run, impossible.
Added to this progress is another decisive factor: battery prices continue to fall. At the same time, new, more sustainable technologies are emerging, with less dependence on critical materials and greater durability. Many of these technologies are not yet on the market, but they will arrive in the coming years and will clearly strengthen the renewable energy generation model.
Cheaper and more efficient batteries mean something very concrete: clean energy available when needed, not just when the sun or wind is shining. This completely changes the game.
Electric mobility: ever closer to the tipping point. Supported by this technological evolution, electric cars continue to improve performance and reduce prices. In many markets, they are already very close to the cost of gasoline vehicles, and in China, they are even cheaper thanks to strong government support.
China, once again, is acting as a driving force behind the global energy transition. The growth of renewables and electric vehicles in that country is spectacular, and its leadership is unquestionable. While others hesitate, China executes, learns quickly, and scales.
It's not all good news, however. One of the major obstacles to the current energy system is the explosive growth of data centers, fueled by the intensive use of Artificial Intelligence. These centers consume enormous amounts of energy and are absorbing a significant portion of the new renewable generation capacity.
It's a paradox of technological progress: we're advancing in efficiency, but at the same time, we're increasing total demand.
Although the overall outlook is moderately positive, we cannot become complacent. The pace of change needed to curb climate change is greater than what is actually happening. Emissions continue to rise, and we are approaching dangerous limits.
Many scientists agree that we have already exceeded the threshold set in the Paris Agreement. The consequences are visible: more intense heat waves, more violent storms, and increasingly frequent extreme weather events.
The most positive note is that the change is not being driven by political rhetoric, but by the real economy and technology. And that combination is far more powerful than any self-serving ideology. When something is cheaper, more efficient, and more competitive, it ultimately prevails.
Looking at the progress made, there are reasons for optimism, but not for complacency. The challenge remains enormous, and the effort ahead considerable. The question is simple:
Do we want to leave our descendants a world similar to the one we inherited, or one worse?
If we don't act with sufficient determination, someone will have every right to hold us accountable.
