What are the "best" renewable energy myths you've heard recently?

I'm on my way to a Renewables in Agriculture conference where I'll be on a panel "Fact vs Fiction:
Setting the record straight on renewable energy" I'm keen to have some good myths to share!

Next-gen geothermal could see faster cost reductions than traditional methods! Unlike traditional geothermal, which faces high exploration risks, new technologies from Quaise, Fervo, and Evor create ideal conditions artificially.

If we could tap into even a tiny fraction of this geothermal energy, it could power the world for millennia with clean energy on demand day and night and no matter the weather or the season. The only problem is that in most places on earth, geothermal power is locked away deep below the surface – too deep to drill, except in those lucky locations where underground reservoirs of steam and hot water exist close to the surface. But new geothermal technologies could make this energy accessible almost anywhere. In this video we’re going to find out how exactly how these technologies are digging deeper and hotter and hoping to bring geothermal from niche to mainstream. And we'll take a look at leading goethermal startups Quaise, Fervo and Eavor to find out their progress and future plans.

Are we running out of critical minerals for EVs? Not really. Reserves are sufficient; the challenge is scaling up mining and refining quickly. Alternative chemistries like LFP and sodium-ion batteries, and rare-earth-free motors, offer flexibility if needed.

EV Myths You Thought Were Facts
Electric vehicles are taking the world by storm, sparking conversations and controversies alike. Are they the green champions of the road or hidden culprits of environmental harm? Can they truly replace the roar of petrol engines without missing a beat? And is our infrastructure ready to support this electric revolution, or will it buckle under the pressure? In this video, we're plugging into the heart of these debates. We'll explore what happens when innovation meets the open road, and whether the journey towards electric mobility is as smooth as the ride in an EV itself. Join me as we navigate through the electric landscape, separating fact from fiction with solid evidence and expert insights. It's time to discover the real story behind electric vehicles.

Is hydrogen hyped only because it's simple to explain? Just burn hydrogen instead of fossil fuels, so simple!

H2 may be the easy answer to "what can we burn instead of fossil fuels?" but it's the right answer to the wrong question according to Paul Martin.

Dunkelflaute - no wind, no sun for weeks - isn't an Australian problem. 42 years of weather data show widespread dips last hours or a day, never weeks.

Floating wind is still small, just 200 MW installed in 16 years. But over 200 GW is in the pipeline. Norway leads, the UK has big plans, and Japan & South Korea see it as key to their energy transitions. Even Australia & China are diving in. Ho... https://youtube.com/shorts/OFofvtPq_mI?feature=share

Can nuclear play nicely with renewables? Its steady output doesn't complement fluctuating demand from wind/solar, needing hydro or batteries to balance.

Nuclear for Australia? Too slow, too expensive & it doesn't fit with renewables. By 2033 90% of our electricity could come from renewables. Why solve problems we don't have, like needing "baseload"? Rooftop solar has killed baseload in Australia. https://www.youtube.com/shorts/WN5siWZHhFg

Chinese wind turbines are pushing the limits with plans for 30 MW models, nearly double today's largest. Bigger turbines mean fewer installations and more power from higher winds.

How do massive wind turbines stay afloat? Designs like Spar buoys, tension leg platforms, and semi-submersibles keep them stable in deep waters and rough seas. There's some amazing engineering behind this, but is it practical? https://youtube.com/shorts/C2rGu6PDGmg?feature=share

A 900 MW water battery in the Swiss Alps, built for €2B over 14 years, is operational. It uses two reservoirs at different elevations to store energy by pumping water uphill and generate power as it flows down. It's 20 GWh, enough to power 400,000 EVs.

If every house in Australia turned on a toaster simultaneously, it'd add nearly half of the grid's average load, causing it to crash. Yet, no one worried about the grid when electric toasters became widespread. So why do we still think that EVs will crash the grid? https://youtu.be/qUDtmom5-vg

Floating offshore wind is expensive, but it unlocks high-wind-speed sites far offshore and in deep waters where fixed-bottom turbines can't go. Plus, no one has to see or hear them. Could floating wind be the answer for untapped energy potential? https://youtube.com/shorts/ElPp6Ri-yko?feature=share

Kite power systems generate electricity by unwinding a tether as the kite ascends, converting mechanical energy to electrical power. Once fully extended, the kite is reeled in using minimal energy, repeating the cycle to maintain continuous operation.

I might have to write off my Peugeot EV that has 2,500km on the odometer. It just needs a firmware update and absolutely no one thinks they can do it as it was originally sold in Japan (now in Australia). Does anyone have any suggestions? Or know who will buy a lightly used 50kWh battery at least 😭😭

It's been a bad week for me on social media, I've had two men chasing me across platforms & searching out alternative contact methods to voice their EXTREME disappointment that my professional opinions differ from theirs.

Seemed like a good time for my first post, are people more respectful here?
