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.

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.

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.

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.

Fossil fuel companies like to promote they pay tax and contribute to teh economcy. In 2022 the gas companies contributed zero. Over 15 years of gas production of $36 billion. A casual food service worker pays more tax than these companies, combined.

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.

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.

Nuclear accidents happen
Summer thunderstorm patterns from Tarong to the Sunshine Coast means the Coast will be in the firing line of any accident at Tarong.

Many argue the US withdrawal from the Paris Agreement is good news. Wind solar and batteries are so cheap that little fossil fuel electricity is being built even in fossil fuel states. The US risks falling behind China in green technologies, and with substantial reductions in oil consumption from EVs by 2030, fossil fuel exports will plummet,

The evidence is clear that nuclear accidents risk polluting large areas with I-131 and Cesium and populations of tens of thousand have increased risk of thyroid cancer. There is no minimum safe exposure, inspite of nuclear advocate misinformation. Nuclear accidents cost billions, and kill thousands indirectly. The risk is simply not worth it.

If California’s 340 billion light-duty vehicle miles went electric, consuming 200 watt-hours per mile, it would require an additional 68 TWh/year, 24% of 2023’s 281 TWh generation. There is 4 times unused natural gas capacity, currently not used. Charging during low-use night hours would utilize this excess, reducing pollution and improving efficiency, enhancing air quality and boost ROI on existing infrastructure.

Most research shows Mistrust in science increasing over the past decades and primarily driven by political polarization, amplified by partisan media and social media algorithms that spread misinformation, with variation observed across age, rural vs. urban populations, and political affiliations. Was it the nuclear bomb, or Rachael Carson, but mistrust is increasing rapidly.

Electrification promises up to 80% of all global energy requirements and can rapidly stop emissions. In this podcast, Lord Adair Turner points out efficient technologies such as heat pumps, electricity for heating water, air, and materials can rapidly change emissions. The focus shifts from energy consumption to energy services for better human welfare. Solar PV costs at 9 cents/watt and batteries under $100/kWh enable transition.
