Important note on graphs showing renewable energy vs primary energy. We're further than what we are commonly told.

[Mark Z. Jacobson @mzjacobson]

Why do people keep showing graphs of primary energy when it is a misleading metric?

Why do people keep showing graphs of primary energy when it tells us nothing about the energy we need or use? The reason is because primary energy exaggerates the role of fossil fuels, biomass and nuclear in the energy supply, so supporters of fossil fuels in particular, like to show primary energy as a way to diminish progress that clean, renewables, such as wind and solar, have made. First, what is primary energy? For coal, oil, gas, biomass, and uranium, it is the energy in the chemical bonds of these fuels. For wind, solar, geothermal, and hydro, it is the energy in the actual electricity produced. Here is why primary energy is misleading. When coal is burned for electricity, two-thirds of coal’s primary energy is lost as waste heat. As such, coal requires three times the primary energy as wind or solar to produce the exact same electricity. Biomass and uranium also require three times the primary energy as wind and solar for electricity. Thus, graphs comparing primary energies of fuels by year show huge fossil-fuel primary energies and tiny wind and solar primary energies. The appropriate metric to use in such graphs is end-use energy. This is the energy directly used by a consumer. It equals primary energy minus the energy lost in converting primary energy to end-use energy, including the energy lost due to waste heat and transmission and distribution. Thus, for coal-electricity, end-use energy is the actual electricity from the coal, after waste heat and transmission and distribution losses are removed. As such, it is comparable, one-for-one, with the end-use electricity from wind and solar. In sum, do not believe graphs that show primary energy. They only mislead about the role of renewables in an energy transition.

Does the world have enough lithium to power all the electric vehicles and stationary batteries needed to transition the world to 100% clean, renewable energy and storage for everything?

The answer is yes. In 2025, the @USGS increased its estimate of world lithium resources over land by 30%, to 150 million tons, with the U.S. having the largest resource, 30 million tons, followed by Argentina, Bolivia, Chile, Australia, and China. How much lithium is this? The world has 1.1 billion passenger cars and 375 million trucks and buses. Replacing these requires about 47 million tons of lithium -- 9 million tons for the cars and 38 million tons for the trucks and buses. That’s only 31 percent of the 2025 known lithium resources, and keep in mind, the known resources grow each year as people look for more lithium. What is more, lithium stays in a vehicle during a battery’s 15 to 25-year life. At the end of the battery’s life, the battery is recycled or re-used for stationary electricity storage, so the mining is one-time. For stationary electricity storage itself, less than one-tenth the lithium, 2 to 4 million tons, is needed worldwide than is needed for vehicles. As such, current lithium resources are over three times those needed for vehicles plus storage. Also, many other battery types now exist that don’t use lithium. In sum, there is no shortage of lithium to transition the world to 100% clean, renewable energy and storage for everything.

Too many headlines are only talking about how a man used ChatGPT to design a cancer vaccine for his dog

But the truth is Paul Conyngham himself stated that the final mRNA vaccine construct for his dog Rosie was actually designed by Grok

This fact is buried deep underground

The exact sequence that shrank her terminal tumor by 75%:
- Sequenced the DNA: He paid $3,000 to sequence both her healthy genome and the tumor's DNA to find the damage

- Analyzed the Mutations: Used AI tools like AlphaFold to compare the data and identify the cancer-specific mutated proteins

- Designed with Grok: He leveraged Grok to design the final custom mRNA vaccine blueprint to target those exact mutations

- Manufactured & Injected: He partnered with university researchers to manufacture the custom nanoparticle vaccine and successfully administered the doses

Every headline is pushing ChatGPT....but the final design that actually shrank the cancer by 75% was done by Grok

As we finish Chamilo 2.0, we are testing the integration of specific AI models in specific contexts. Nano Banana is great to generate illustrations for documents, Grok is great for last-minute knowledge in tutoring chatbots and generation of STEM-related tests, etc
What a time to be alive!

Sweden is committing more than €100 million to a sweeping classroom overhaul: replacing tablets and screens with traditional printed textbooks to help reverse falling student performance and sharpen focus.

After more than a decade of embracing digital-first education, Swedish authorities are now pivoting back to paper-based learning. Official data and recent studies cited by the Ministry of Education show that prolonged screen use in class has been linked to shorter attention spans, weaker reading comprehension, and reduced critical-thinking abilities.

Research consistently finds that reading on illuminated screens requires greater mental effort and invites more distractions compared to the calm, linear experience of physical books—factors believed to have contributed to declining academic outcomes in recent years.

Under the new plan, every student will receive printed textbooks for all core subjects, restoring books as the central learning tool. Digital devices and online resources will remain available as supportive tools, but they will no longer dominate daily instruction.

This bold €100+ million investment signals Sweden’s leadership in rethinking the role of technology in education. It underscores a broader, growing recognition worldwide: while screens provide speed and access, the hands-on, distraction-free engagement of physical books supports deeper concentration, stronger memory retention, and more effective long-term learning.

By choosing paper over pixels, Sweden is charting a path toward a more balanced, evidence-informed classroom future—one that puts proven pedagogical principles ahead of unchecked digital trends.

French agrivoltaics trials show crops under solar panels had up to 18% higher yields, far fewer heat-stress days, cooler soils, and better animal welfare — while generating clean power. This is a win-win governments should scale now.
