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! renewablesinagconference.com.au

😱 4 years of YouTubing and my little channel is about to be all grown up at 100k subs! Thanks everyone who has ever watched, liked, shared or commented on an Engineering with Rosie video! And if you're not yet a subscriber, you have the chance to be #100000 www.youtube.com/c/engineeringwithrosie

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. Watch the full video here on YouTube: https://youtu.be/vXue9EQt-Wg

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. https://youtu.be/C0ZtX5d-WE0

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. https://youtube.com/shorts/my2vo1J5pOU

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. Winter monthly output has never been lower than 70% of average. Long duration energy storage... https://youtube.com/shorts/kiKCnACikpY?feature=share

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

So far, all floating wind farms have used standard offshore turbines on floating substructures. But new designs are emerging: vertical axis turbines for lower centers of gravity, multirotor designs to avoid massive rotors, and innovations in to... https://youtube.com/shorts/IzDAiAJ3mYE?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. Countries like Sweden manage it with hydro, but no grids have a lot of nuclear and a lot of... https://youtube.com/shorts/0lixZkq62No?feature=share

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. But engineering limits mean there's a trade-off. At some point, size doesn't a... https://youtube.com/shorts/NYagH0rQBt8

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. https://youtube.com/shorts/T2ctLzuG-ig

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

Forget hours of charging - new 500kW wireless tech can fully power up a long-haul electric truck in just 15 minutes! 🤯 That's like getting your home's energy for a whole day in just 3.6 minutes, without any cables! https://youtube.com/shorts/RTM8vmRs2mY

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. https://youtube.com/shorts/zk3LlnlT0jU

The world's largest sand battery is coming to Finland. With 100 MWh capacity, it can store excess solar/wind energy and cut district heating emissions by 70%. Heat stays at 500°C for months, replacing oil & woodchips. https://youtube.com/shorts/KkiJOT9F8B8

Ditch the charging cable! 🔌 Is wireless charging for EVs about to go mainstream? 🔋 See how this tech works like an induction stove to power up your ride. 🔌🚗 https://youtube.com/shorts/3eQVnwzeK5M

Floating wind power has come a long way, from an 80 kW prototype in 2007 to Hywind Tampen in 2023, the world's largest floating wind farm powering offshore oil platforms. How much further can this technology go? https://youtube.com/shorts/s1WxCiWN9gQ?feature=share

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?
