At Everything Electric UK 2025, pushed as both car and house, the house energy was very subdued. Most of the show where new EVs into UK. From Hyundai, to BYD, Geely, GWM, and Zeckr there are Chinese cars gallore. Octipus had a range of dozens of cars to suit lease with free charging.

Deep-sea mineral mining is a proposed industry that aims to extract valuable minerals from the ocean floor. While it offers potential benefits for meeting the growing global demand for metals, it also poses significant environmental risk. The pros and cons are shown to provie little benefit to the supply of minerals but the money speaks. More destruction likelu
Actor network theory or ANT described by Bruno Latour can be used to understand why the world thought hydrogen was a critical part of carbon emissions reduction to mitigate climate change. Turns out that the black box of Hydrogen is a myth. Based on faulty science, supported by subsidies to support existing fossil fuel companies. Thankfully is dying as the box is exposed.

A detailed look at solar panel recycling. The egulators are aware and have pilot programs in place and ready to scale for up to ensure the tsunami of panels from 2030 can be recycled. A challenge is cost and over 80% are currently landfilled. By 2030 with right policies that can be brought up to over 60% or higher.

Solar panels can be recycled. To date, there has been no legal requirement to do so, but governments are now mandating and the purchase price will includee recycling costs. The latest innovation is to recycle 98% profitably with recovery of all components and even recycling of silicon and glass, rather than repurpose.

Green hydrogen may not be green. Blue hydrogen may be worse than other hydrogen colours if the methane gas has leaks. Depending on the source of methane, electricity the climate change emissions of hydrogen varies by source, electrolyser efficiency, carbon capture and storage efficiency. The life cycle analysis needs to be done on all hydrogen projects to see how they can reduce carbon emissions.

Geothermal energy, although currently contributing less than 1% to global energy production, has the potential to supply 140 times the world’s energy demand. Next-generation geothermal, including engineered, advanced, and hybrid systems, can be used for heating, cooling, and power generation . Scaling geothermal requires leveraging the oil and gas industry’s expertise and infrastructure.

Fuel costs of large trucks suggest electric class 8 trucks would be economic. Turns out labour costs is the major item. Will humanoid robots or autonomous vehicles reduce operating cost so much that autonomous trucks take over trucking.

Global electric truck sales are growing with sales in 2024 over 90,000 units and a year-on-year growth rate of almost 80%. Surge is largely driven by China, where sales more than doubled between 2023 and 2024, accounting for over 80% of global sales. China leads the way, but other markets increase electric truck adoption. With Tesla Semi soon to be produced, trucks will surge.

Renewable energy produced locally regains sovereignty when fossil fuel is gone. Countries regain sovereignty when they no longer have to buy their energy from fossil fuel rich countries. Fossil fuel exports provide luxury for about 24 countries – the rest of the 160 countries are dependent on importing oil gas and coal.

Inertia in electricity grids is a term used in electricity grids describing the behaviour of voltage. Many think solar and wind won’t be able to keep the grid stable because they lack “inertia”. Solar, wind and batteries will probably do a BETTER job and you can explain it

Hydrogen itself is not a direct greenhouse gas, as it does not absorb infrared radiation. However, evidence suggests it acts as an indirect greenhouse gas. When released, it extends methane’s atmospheric lifetime, increases tropospheric ozone, and adds stratospheric water vapor, all of which contribute to warming. Studies estimate its 100-year Global Warming Potential at 11.6 ± 2.8.

Lethal humidity is a dangerous combination of high heat and high humidity, measured by wet-bulb temperature. When humidity is too high, sweat cannot evaporate from the skin, preventing the body from cooling itself. This causes core body temperature to rise rapidly, leading to heatstroke, organ failure, and potentially death within hours. Climate change increases frequency and intensity of these life-threatening conditions especially in Middle East, India and South East Asia
Hydrogen will be an essential fuel for the zero emissions economy says Dr Andrew Forrest in an interview on Cleaning Up Eps 210. With a 80% reduction in size, and an increase in efficiency to 96%, green hydrogen ammonia will move ships and enable green steel.

Genealogy is in vogue. Multiple TV series. But which software to use? The options are relatively limited. If you don’t have IT skills, then use an online system such as Ancestry or My Heritage. If you are more proficient, use one of the many desktop systems including Family Tree Maker, Roots Magic, Family Hittorian to make more complete trees.

Wartsilar, better known for shipping engines in their modelling says 98% net zero by 2050 is cheaper than 100% WWS by Prof Jacobson. Meanwhile 100% is possible says Prof Mark Jacobson.
RethinkiX says Stellar enegy – 500% is most cost effective for superabundant energy.
Wartsilar fails the fossil fuel argument and keeps about 12,000 TWh of generation in the mix – albeit for just 3% of the electricity generation. The world demands 100% zero emissions, not net zero.

Australia needs to lift its ban on balcony solar and battery systems. A balcony system in 25 European countries is up to 2kW of PV sol;ar and 800W battery. An apartment could save up to 30% of its electricity bill and pay back the system in less than 6 years. Landlords cannot prevent approved systems.

Twenty companies are responsible for 40% of emissions globally in 2023. Over 2/3rds of them are state owned. Since 1750, just 25 entities have created the climate crisis we are currently facing. Carbon Majors have released their 2023 report and shows emissions continue to rise with over 180 companies contributing to emissions globally.

How to provide cost of living help, electrify the grid, and reduce 40% of Australia’s emissions? In 12 months? The govt could step in and provide buy 2 million household batteries for 40GWh. Customers would repay $60 per month interest free through their electricity retailer.
Cost is less than existing programs and subsidies.
