In a recent LinkedIn post, Bill Gates shares a message of cautious optimism, highlighting significant advancements in climate and global health during what he describes as an “exceptionally difficult time” in 2025. While acknowledging the “terrible tragedies and serious setbacks” of the year, Gates focuses on progress that largely went unnoticed, offering reasons for hope as the world looks toward 2026.
Renewable Energy Surges Ahead
A key takeaway from Gates’s post is the landmark achievement in renewable energy. For the first time in history, renewable sources have surpassed coal in global electricity generation. According to Gates,
“For the first time ever, renewable energy has officially overtaken coal as the world’s top power source. In the first half of 2025, renewables generated 34% of global electricity, moving past coal’s 33%.”
This shift, as detailed in the post, signifies a critical turning point in the global energy landscape. Gates also points to the increasing adoption of geothermal energy, noting its benefits as a steady, low-emission power source that can operate 24/7 and even serve as large-scale energy storage.
Breakthroughs in Global Health
The post also shines a light on substantial progress in global health, particularly in the fight against Alzheimer’s disease and infectious diseases. Gates highlights the U.S. Food and Drug Administration’s approval of the first blood-based biomarker tests for Alzheimer’s detection. This innovation promises to make early diagnosis more accessible by eliminating the need for more invasive procedures like lumbar punctures or PET scans.
Furthermore, Gates discusses advancements in Alzheimer’s treatment, mentioning the promising new drug Trontinemab. He explains the significance of its “brain shuttle” technology, which aims to deliver medication more effectively for clearing amyloid plaques.
The progress in combating infectious diseases is also a central theme. Twelve countries have received World Health Organization (WHO) validation for eliminating long-standing infectious diseases, and nine have achieved similar validation for eliminating neglected tropical diseases. Gates emphasizes the impact of long-acting prevention tools, such as the twice-yearly injectable PrEP option, Lenacapavir, approved by the FDA for HIV prevention.
“Long-acting prevention tools like this have the potential to dramatically expand protection worldwide.”
In the realm of vaccines and disease prevention, Gates celebrates the milestone reached by Gavi, the Vaccine Alliance, which has protected an estimated 86 million girls with the HPV vaccine, potentially preventing millions of future cervical cancer deaths. The shift to a single-dose immunization schedule is noted as a crucial factor in expanding access, especially in low- and middle-income countries.
Looking Ahead with Hope
The article also touches upon a significant breakthrough in malaria research, with a new treatment, GanLum, showing 99% effectiveness in late-stage trials. If approved, this would represent the first major advancement in malaria treatment in over a quarter-century.
Concluding his post, Bill Gates reiterates the importance of recognizing these achievements. As he puts it,
“As we head into 2026, it’s worth pausing to recognize these breakthroughs and moments of real progress. They’re a reminder that innovation—and collaboration—can and does move the world forward.”
Gates’s message underscores the idea that despite facing considerable global challenges, persistent innovation and collaborative efforts continue to yield substantial positive outcomes in critical areas like climate and public health.
