  • Global Electricity Review 2025: Key Insights & What They Mean for Our Energy Future
    May 17 2025
    The recently released Global Electricity Review 2025 by Ember provides a crucial snapshot of our current energy landscape. It marks significant milestones while also highlighting the complex path ahead in the global Energy Transition. This article breaks down the key findings and explores their implications. To make these important insights more accessible, I’ve also created a video that walks through the core data. A New Milestone: Over 40% Low-Carbon Power GloballyFor the first time since the 1940s, a significant threshold has been crossed in global electricity generation. According to the Global Electricity Review 2025, generation from all low-carbon power sources — which includes renewables and nuclear — surpassed 40% of global electricity in 2024. Specifically, these sources reached 40.9% of the global mix, a notable increase from 39.4% in 2023.This is a landmark achievement, especially considering the global electricity system today is 50 times larger than it was in the 1940s. This shift underscores a clear momentum in the decarbonization of our power sector, even as overall energy needs continue to evolve. While various sources contribute to this figure, the growth has been particularly propelled by the rapid expansion of renewable technologies.Solar Power: The Undisputed Engine of GrowthThe report leaves no doubt: solar power has become the engine of the global energy transition. For the third consecutive year, solar was the largest source of new electricity generation globally, adding a remarkable 474 TWh in 2024. This represents a stunning 29% growth from the previous year, making it the fastest-growing source of electricity for the 20th year in a row.The scale and speed of solar’s ascent are extraordinary. Solar generation has effectively doubled in the last three years, reaching 2,131 TWh in 2024 — a volume now sufficient to power all of India. This exponential growth is also reflected in capacity: after surpassing 1 Terawatt (TW) of global solar power capacity in 2022, it took only two more years to install the next 1 TW, reaching 2 TW in 2024. This highlights solar energy’s critical role in meeting rising electricity demand and displacing fossil fuels.Rising Demand & New Drivers: A Complex ChallengeDespite the progress in clean energy generation, the global electricity demand itself is on an upward trajectory. In 2024, global electricity demand grew by a significant 4.0% (+1,172 TWh), crossing the 30,000 TWh threshold for the first time. This was the third-largest percentage growth in the last decade.A notable factor in this demand increase was the impact of heatwaves, which amplified demand by an estimated 0.7% (+208 TWh) due to increased cooling needs. Beyond weather-related impacts, new structural drivers are also pushing demand higher. Technologies like electric vehicles (EVs), heat pumps, and particularly data centers (including those for AI and cryptocurrency mining) contributed a combined 0.7% (+195 TWh) to annual demand growth in 2024. This contribution from new technologies is more than twice what it was just five years ago, signaling a substantial shift in consumption patterns that the energy transition must accommodate.The Shifting Fossil Fuel LandscapeThe rise in overall electricity demand, particularly due to extreme weather, had a direct impact on fossil fuel generation in 2024. Global fossil fuel generation increased by 1.4% (+245 TWh), leading to a 1.6% rise in global power sector emissions, which reached a new record high.However, the report offers crucial nuance: this increase was primarily a result of hotter temperatures compared to 2023. Had temperatures remained the same, fossil fuel generation would have seen only a minimal 0.2% increase, as the record surge in clean electricity generation (927 TWh in 2024) was sufficient to cover 96% of the non-temperature-related demand growth. Looking ahead, the report indicates that fossil fuel generation is set for a structural decline over the rest of the decade, as accelerated clean generation is expected to consistently outpace structural demand growth. The “era of fossil growth is coming to an end,” as stated by Ember’s Managing Director, Phil MacDonald.The Road Ahead: Flexibility, Storage, and Global CollaborationTo effectively integrate the rapidly growing share of variable renewables like solar and wind, the development of flexibility solutions is paramount. Battery storage technology is emerging as a crucial enabler. Driven by falling costs (the average price of lithium-ion battery packs dropped by 20% in 2024), a record 69 GW of battery storage capacity was installed globally in 2024, nearly doubling the total installed capacity. This cost-competitiveness is even opening doors for concepts like 24-hour solar power projects.The success of the global energy transition will also heavily depend on the trajectory of major economies. The report highlights that China and India are pivotal, as they are ...

  • Stanford’s NNetNav: How Childlike Learning Could Revolutionize Open-Source AI
    Mar 29 2025

    Can a machine learn like a child? Stanford’s groundbreaking project NNetNav challenges the dominant paradigm of training large language models on static datasets. By interacting with the web like a curious human—clicking, exploring, and even making mistakes—it opens a bold new path in AI development.What is NNetNav?

    Developed by researchers like Shikhar Murty and Prof. Chris Manning at Stanford, NNetNav explores the web through trial-and-error—without needing human-labelled data.

    Childlike Learning vs. Ingestive Models

    Unlike conventional LLMs, which consume fixed datasets, NNetNav generates its own data by engaging with websites. It clicks buttons, fills forms, and learns by doing—mirroring how children learn through direct interaction.

    Smaller Yet Smarter

    NNetNav runs on ~1/3 fewer parameters compared to GPT-4-level models, but still achieves strong results. This raises profound questions about efficiency, sufficiency, and the future of model scaling.

    Privacy, Ethics, and Open Source

    By being open-source, NNetNav offers a transparent alternative to closed models. It also highlights emerging ethical challenges: What happens when AIs learn autonomously in the wild?

    Real-World Applications

    Imagine a system that books flights, extracts business data, or navigates insurance portals—all without being hardcoded. NNetNav points toward self-taught agents that can adapt flexibly to new environments.

    Implications for Education and Human-AI Collaboration

    NNetNav’s principles echo educational research: interaction fosters deeper understanding. Could this inspire new forms of AI-human synergy—in classrooms, coding environments, or even therapy?

    The Road Ahead

    Reinforcement learning, curriculum design, and “learning on the fly” will likely enhance this approach. Stanford’s open-source release invites further exploration—and competition.Original Stanford article:

  • Navigating Unpredictability: Building an Anti-Fragile Digital Infrastructure
    Mar 19 2025

    In our increasingly algorithm-driven world, individuals find themselves caught in a paradox: while algorithms determine the content we consume, our limited control over these digital environments poses challenges to personal and professional growth. The solution lies in strategically diversifying our digital presence — leveraging multiple platforms to foster competition, personal development, and resilience.

    The Algorithmic Trap: Why Your Focus Matters

    Every click, like, or share feeds machine-learning algorithms designed primarily to maximize user engagement. These algorithms rely exclusively on the personal data and behaviors we consciously or subconsciously reveal online. Consequently, our digital footprint shapes the type of content we encounter and the connections we form.

    For instance, regularly engaging with intellectually stimulating content — such as scientific articles, advanced technological innovations, or professional forums — prompts algorithms to present increasingly sophisticated and growth-oriented information. Conversely, frequent interactions with purely entertainment-driven content, like humorous pet videos, constrict your digital ecosystem, limiting exposure to valuable opportunities for personal or professional expansion.

    Anti-Fragility in the Digital Age: Leveraging Uncertainty

    Anti-fragility, a concept popularized by Nassim Nicholas Taleb, refers to systems that grow stronger from stressors and shocks rather than merely resisting them. Translating this idea into a digital context, an anti-fragile digital infrastructure enables individuals to flourish amid uncertainty, harnessing algorithmic unpredictability for personal advantage.

    Key steps to create an anti-fragile digital presence include:

    * Deliberate Data Sharing: Intentionally engage with high-value, knowledge-rich content across various platforms.

    * Cross-Platform Diversification: Do not confine your digital interactions to a single platform. Instead, strategically spread your online presence across multiple environments — LinkedIn, Medium, Substrack, Quora, Bluesky, Mastodon, X, YouTube, Instagram, Threads, Reddit, and specialized forums.

    * Active Content Curation: Regularly refine and adjust the types of interactions you have, prompting algorithms to elevate the quality and relevance of your digital feed.

    Strategic Diversification: Letting Platforms Compete for Your Growth

    Digital platforms inherently compete for two critical resources: user attention and user-generated data. When your digital presence spans multiple platforms, each must strive to maximize the utility and relevance of the data collected from your interactions. This competition inherently elevates the quality of content presented, optimizing your personal and professional growth opportunities.

    For example, cultivating a professional presence on LinkedIn while engaging intellectually on Medium and debating niche industry insights on specialized forums ensures that each platform attempts to offer unique, meaningful experiences to retain your attention. The beneficial side-effect: your digital landscape becomes a powerful catalyst for intellectual and professional advancement.

    Ethical and Psychological Dimensions: Awareness and Adaptation

    Recognizing the inherent limitations of individual influence within algorithmically driven platforms is crucial. Yet, awareness itself provides a powerful leverage point — guiding intentional behavior to foster personal growth despite these constraints. Ethical self-management involves being cognizant of privacy concerns, data rights, and personal agency.

    Actionable Steps: A Checklist for Digital Anti-Fragility

    * Be aware you ulimatively can’t control the (digital) world, but you can Control your own thoughts and attention

    * Act based in yout own attention, your true self and not just something the digital platforms can make Money with, yet

    Conclusion: Your Digital Footprint, Your Growth Catalyst

    Though we cannot directly control algorithmic behaviors, strategically managing our digital presence across various platforms empowers us to leverage unpredictability for personal and professional benefit. By fostering competitive dynamics among platforms, we effectively turn algorithmic dependence into a robust mechanism for lifelong learning, connection, and growth.

    In an unpredictable digital age, your conscious, intentional actions are your strongest tool.
