Hydrogen Dead End in China
China is a good comparison of hydrogen fuel cell vehicles. In Foshan city an H2 tram has been mothball and when you look at all cars and public transport, it is hard to see where the use case for hydrogen is.
Climate Refugees Increasing Fact vs Fiction
Climate change is a pressing global issue with far-reaching consequences. Climate change refugees have increased 41% since 2008 with over 32 million refugees today. UNHCR debunks 5 myths with facts highlighting the urgent need for action. Key points include the growing number of people displaced by climate-related disasters, the challenges of predicting future displacement, and the importance of both mitigation and adaptation efforts. We must stope emissions, and build more resilient and sustainable future for all.
Vaccines Saved 154 million Lives
The Expanded Programme on Immunization (EPI) has been a cornerstone of global health, saving over 150 million lives and improving health outcomes worldwide. Through its comprehensive approach and the impact of vaccines like measles, EPI has demonstrated the power of vaccination in reducing mortality, promoting equity, and protecting individuals throughout their lifespan.
Coal to Build Wind Turbines
While over 260t steel, 300t iron ore, 170t coking coal are used to build a 4MW wind turbine, the energy from a wind turbine is 660 times more. The wind turbine produces 420GWh electricity over its 30-year life, while the equivalent amount of coal electricity would require 290,988t of coal. Therefore, wind energy is a much cleaner and more sustainable option.
25 Factors in Battery Systems
Batteries are essential components in modern technology. From smartphones to electric vehicles, they store and deliver energy efficiently. Understanding battery systems involves factors like chemistry, capacity, and management. Proper maintenance and disposal are crucial for ensuring their longevity and environmental sustainability.
Batteries Last 40 Years with Latest Research
A new study challenges conventional wisdom in EV battery manufacturing. Researchers found that fast charging, despite initial lithium loss, can significantly extend battery lifespan. This could lead to more efficient and sustainable electric vehicles and extend grid storage batteries to decades
Enough Solar Panels for 100% Electricity in 4 Years
With solar panel production capacity of China over 1TW PV in 2024 is enough to replace 4.5% fossil fuel electricity generation, with 100% by 2028. China faces an industry collapse of companies making solar panels. Either panels must be deployed globally or there will be a sector collapse.

Nuclear is Not Safe
Nuclear power is riskier than previously thought with failure rate of 1 per 3704 reactor years. That’s about 1 per decade. Despite safety improvements, severe accidents remain a concern. Limited data from the IAEA hinders thorough analysis.
Earth Energy Imbalance Visualization
Earth’s energy imbalance EEI is caused by greenhouse gases. Leon Simons uses analogies (bombs, sunlight) to show the immense amount of heat trapped (20 ZJ/year). This trapped heat is 33x humanity’s annual energy use and could raise sea levels by 15cm. The goal is to visualize the vast amount of heat our actions cause.
George Monbiot Precision Fermentation
Environmentalist George Monbiot believes precision fermentation can revolutionize food production. He dismisses concerns about factory processing and genetically modified organisms, arguing that these technologies offer a more sustainable and ethical alternative to traditional livestock farming. While corporate control is a risk, Monbiot emphasizes the technology’s potential to reduce environmental harm.
Energy Breakthroughs Drives Transportation: History Repeats
As Professor Vaclav Smil highlights in “Grand Transitions,” coal, oil, and now solar power have dramatically reshaped transportation and society. Harnessing the sun’s energy promises to end fossil fuel dependency, disrupt industries, and lift billions out of energy poverty.

Dementia Diagnosis and Treatment Advances
Recent advancements in AI, particularly in early diagnosis and treatment of dementia, provide a glimmer of hope. Dementia, a major global health challenge, is expected to affect 153 million by 2050. AI detection and lifestyle changes like exercise can delay onset, while new drugs like Donanemab offer promising, albeit expensive, therapies.
Great Gas Giveaway
Australia’s government subsidizes the fossil fuel industry, emphasizing gas fields in its strategy despite environmental concerns. Critics argue this undermines emissions targets and misses potential royalty revenues. The policy supports export-focused gas development, risking public funds for decommissioning costs while contradicting net-zero ambitions and favoring fossil fuel interests.
Australian Gas Exports Will Crash
Australia gas strategy emphasizes new gas fields, causing concerns about climate goals due to rising emissions. Australia’s gas exports face a declining future, with major markets reducing demand and increased competition from the USA and Qatar. Thermal batteries may assist in industrial decarbonisation but the biggest threat is all countries are moving rapidly to reduce gas demand. Decommissioning liabilities heighten taxpayer risks.
Gas Transition to Electric In Australia
As Australia transitions from fossil fuels to electricity by 2030, rapid shifts will mainly impact domestic gas consumption. New gas fields, key to government policy, are controversial due to their potential to hinder emissions reductions. The shift includes household electrification, increased renewable energy storage, and industrial process heat alternatives. Export markets face competition risks.
Tesla Achievements 2018 to 2024
From 2018 to mid-2024, Tesla achieved significant milestones, including delivering millions of vehicles globally, advancing energy storage deployments, and expanding its Supercharger network. Notable accomplishments are the unveiling of new models, expanding autonomous driving features, and achieving profitability. Production has become more efficient, and several new technologies, including FSD and Optimus robots, were developed.
153 Countries 100% Renewable Energy
A decade after Prof. Mark Jacobson’s 2015 proposal for 100% renewable energy in 153 countries, significant debates continue. Despite initial challenges and legal disputes, Jacobson defended his model, though some technological predictions, like concentrated solar power, fell short. Notably, California’s renewable energy achievements in 2024 affirm the feasibility and importance of his vision.
Advances in Thorium Nuclear Reactors
India and China have made considerable progress in developing thorium-based nuclear reactors, recognizing their potential as safer, more sustainable alternatives to uranium reactors. India’s program focuses on the Advanced Heavy Water Reactor using thorium and a small amount of uranium-233, while China’s involves pioneering molten salt technology in the Chinese Thorium Molten Salt Reactor project. Alongside, companies like Copenhagen Atomic are also advancing thorium technology, facing challenges like isotope production and corrosion-resistant materials.
Electricity for AI Exceeds Transportation
AI computing’s surge outpaces electricity demand for transportation, potentially exceeding it due to expansive training and inference needs. Massive datacenters from tech giants necessitate immense power, raising speculation about electricity shortages. Tesla leads with significant investments in low-power and high-performance chips, aiming for exascale AI capabilities. This growth in AI computation could increase datacenter electricity use fourfold within a decade, challenging current power grids and possibly requiring dedicated power plants to meet escalating energy demands.
Stellantis Flawed Hydrogen Strategy
Previously we outlined ten reasons hydrogen was dead for transportation, yet we see Stellantis flawed hydrogen strategy proposed by the CEO. Despite Carolos Tavares says in an online event that the cost of hydrogen mobility is ‘sky high’, just two months after introducing eight new H2 van models.
