Why are people determined to believe that wind turbines kill whales

Coastal Australia is having another flare-up where locals are suggesting that wind turbines are killing whales. If this were the case, it would mean that those who want to save the planet would need to choose between climate change and conservation of whales.

Pictures put up, include images of whales on fire, among others – paid for Newcastle adn Port Stephens Game Fish Club. They suggested that the posters highlighted risks that were known for the whales, but there is no credible evidence that wind turbines have any impact on whales (except during building, but as the picture shows this is short-lived). Indeed Quentin Hanich who is the editor of the academic journal Marine Policy recently had to spend a week debunking a fake article that purported to come from his publication, which claimed that 400 whales would die a year, if a proposed wind farm went ahead. While the facebook post where it originated was taken down, the fake articles can be written far faster than they can be taken down. This offshore wind farm in New south Wales, is opposed by everyone from locals to MPs from outside the region – usually because the are opposed to renewable energy development.

This seems short-sighted- while Australia does have a large coal industry, most is exported (only around 30% is used in the country, and coal in electricity generation is now so much more expensive than almost any renewable generation, that its days are numbered) and of Japan,South Korea, Taiwan,and India which takes the majority, only India does not have a 2050 pledge of zero carbon – so if those promises are to be kept, the market for most of the coal will disappear within the next 25 years.

Opposition has been fanned by the coalition, and people like Baraby Joyce (a renewable energy opponent and climate change denier) have been loudly stating that support for renewables was a cult and the people should fight back.

Amanda De Lore is also fighting against it, and suggest that the 3 month consultation period was rushed and hidden (it was not) and that offshore wind is “not clean, green energy”. She stated that the project was not taking her groups concerns into consideration. However, when concerns are raised which do not conform with reality (like suggesting that offshore wind turbines are not green) they should be ignored. Importantly, when you compare the death toll of offshore wind turbines to a coal power plant, the numbers are stark with thousands more species killed by coal power.

This is part of the issue with public consultation. When opponents lace the population with falsehoods, you find yourself having to engage in a years-long effort to correct, before you can even have an intelligent conversation.

Stored carbon dioxide ( the so-called Carbon dome) could become a giant battery, but will batteries kill it?

Huge carbon dioxide stores, with the gas held at high pressure (and therefore liquid, have been shown to be able to hold vast amounts of energy, and the ability to be released on demand.

Energy Dome’s CO2 Battery system has currently been show to be able to store and generate up to 24.5 megawatts (MW) of power (with 12 acres expected to be able to store up to 200MW), which sounds very impressive…. but…. current battery power means that 1 MW of battery can fit in a 20 by 40 foot container, which means that 1 acre could theoretically take 200MW of batteries.

When first thought of, it was thought that this would allow energy done to store energy at a cost of roughly $200 per kwh. At the time, lithium batteries cost $300 per kwh, however this has halved to just $150.

In other words, lithium batteries (and this assumes no breakthrough in sodium batteries or something else) are cheaper, smaller, simpler and safer – so why would you look to create another form of electricity storage, that is worse on so many levels.

The UK clean energy targets will be missed without £48 billion

The UK has set a hard target of 100% green electricity by 2030, but unfortunately, at the current time, its investments are not keeping up with its targets.

It is estimated that the UK need £48 billion to get to this target in time. This target would require a doubling of the onshore wind capacity, a tripling of solar power and a quadrupling of offshore wind capacity.

The current thinking, is that the UK is just half way to the wind energy target in 2030, however with solar it is worse. Currently we have roughly 15GW installed capacity, but it is predicted that we need 70GW to meet our target. Current progress suggests that we will hit 44% renewable by then, which is far short of the 69% that would be required.

What is worse, is that at this rate, gas will still account for 29% of energy which would be more than the individual contribution of Solar, onshore wind or offshore wind. It should be noted, that it is thought that meeting this target on time, will be worth far more in savings, but there does not seem to be enough urgency from the UK government to push this forwards.

It should be noted, that we have just had a change of government, and if Labour continues as it has started, we should get back on track.

In the summer, a government report found that the policies put in place by Rishi Sunak were only good enough to meet roughly 1/3 of the carbon reduction that we had pledged to make in the Paris climate agreement of 68%.

Largest offshore windfarm just powered up, and its just off UK

This vast wind farm can produce around 3.6 gigawatts of power when turned on. To put that in perspective, peak demand in the UK is currently around 61 gigawatt hours, This means that even at peak demand, this wind turbine is capable of providing roughly 5% of the UK power demand. By contrast, the average house in the UK has a low-point in power demand, during the night, when around 0.2kwh is used an hour. This equates to around 5gigawatt hours. In other words, this single wind farm is likely to be able to deal with all baseload demands of the UK housing. Of course there is other demand, from shop lights being left on, to night shifts in factories.

However, what is clear, is that this is a significant amount of power, and is likely to greatly reduce the amount of gas required to be burnt for power production.

Given that this adds to the already installed stock, we now can create around 30gwh of electricity from wind – when it is at its peak.

Now, of course the wind does not blow at this required rate to produce the maximum amount of power 24 hours a day, so these numbers are not available all day.

To put these numbers in context, in 2022, wind delivered around 26% of UK electricity. Given all the large wind farms planned, this will grow.
