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.

The end of coal powered electricity generation in the UK? Where is the rest of the world on cleaning their power generation

The last coal powered power plant in the UK is having its last day today, before it is closed down

The shrink in the electricity generation in the UK for coal, has been quite astounding. in 2006, coal produced 37% of the electricity for the UK, dropping to zero by 2024.

Holborn Viaduct was the first coal power plant, opened in 1882 (In the early 1800s, coal was used to make town gas for lighting and to fuel the expansion of Britain’s burgeoning railways, but not for electricity).

It is estimated that the UK has burnt 4.6 billion tonnes of coal since this time, emitting a little over 10 billion tonnes of carbon dioxide.

Greece and the U.K. achieved the fastest coal power reductions — moving at a quicker pace than what’s needed globally but Denmark, Spain, Portugal, Israel, Romania, Germany, the United States and Chile are all not too far behind. However, there is still a huge amount of work to be done. Coal, the most polluting fossil fuel, supplied 36% of electricity generation in 2022. This must drop to 4% by 2030 and then 0% by 2040 if the world is to limit global warming to 1.5 degrees C and prevent the most catastrophic impacts of the climate crisis. This is frankly an astounding rate of decline, and there are many countries around the world, who will have to be supported, if we are to meet this requirement.

Paradoxically, the USA also appears on the list of countries furthest from phasing out coal, along with India and China. It is quite feasible for the USA to cut its way to coal at a surprising rate (though whether Trump returns to the White house, or Kamala moves from the vice presidents wing, to the presidents wing, is likely to have a big impact on whether coal is left behind in the USA or not)

It is true that coal is the most dirty fuel, but we still have a great deal of work to do as a species, if we are to avoid the worst of global warming. It is thought that we have just 6 years to stop burning gas, and this accounts for around 22% of global electricity generation. In much of the west, gas is also used for heating, and while there are alternative options (we had a heat pump installed this year, after it was clear that our boiler was failing). 73.8% of UK houses are heated in this way, and so there is clearing a big need for the transition to occur faster.

In the UK, all electricity generation is meant to be carbon neutral by 2035, so gas must disappear by then – though as the financial penalties for continuing to burn things and the cost of other electricity generation falls, the financial imperative to end gas power plant use, is only going to increase, so we may well get there far faster. It should be noted, that the government also has a 95% electricity generation target in 2030, so gas must reduce fast over the next 5-6 years.

Currently, wind power generation accounts for 30 gigawatt hours, but the 2030 target is 50, and solar generation is targeting a 5 fold increase in the amount of generation by 2035. These two alone, will greatly outweigh the loss of gas.

Of course, you can save money in almost any part of the world, but installing solar (we nearly have ours working) will not only help in cleaning up the grid, but our investment, is likely to be paid back from savings in around 3 years.

In the global south, it is even easier to make this work.

Transforming coal into protein for livestock feed uses 0.1% of the space!

Currently, land given over to growing animal feed accounts for 40 million square kg (15.4 million square miles). Given the worlds land mass accounts for almost 60 million square miles (160 million square km( this is a significant increase). This amount of land, freed up, could potentially allow a huge improvement in the amount of space given over to wilderness on the earth.

So where would we get protein for livestock feed?

Chinese scientists have created a method which allows the conversion of coal into protein – far more effectively than with plants. 0.1% of this land is required in this new system. It is true that this still accounts for 60,000 square miles,

So the process has a number of steps.

  1. The coal is transfored into methanol via gasification (this can now be done with a near zero carbon emissions)
  2. The methane is then fed to a special strain of Pichia pastoris yeast, which ferments the methanol, in order to produce a single-cell protein complete with a range of amino acids, vitamins, inorganic salts, fats and carbohydrates. There is far more protein in this than in plants and it can be used to partially replace the protein currently used

The conversion efficiency is at a remarkable 92%. This means that it is a cost effective replacement. Now, how much of the protein can be replaced, however a trial facility has already produced thousands of tonnes of this protein.

So if we assume that it cannot replace all of the protein, it seems reasonable to be able to replace 50% or 80% of the protein.

Even countries like the USA could free up thousands of square miles.

The idea that we could free up 30 -48 millions square kilometres (7.5 to 12 million square miles) to be returned to wilderness and carbon sinks among other purposes. If just half of this land was rewilded, it would allow large amounts of the land around the world to return to a wild state, which would help us cut emissions.

Now, it is true that this coal will be emitted as carbon at the end of the line, but if enough of the freed land is used for forest and similar, the net carbon gain can be huge.

Indonesia has signed a $20 billion deal with the G7 to accelerate their clean energy transition

The clean energy transition is accelerating in some parts of the world. It is often cheaper to install solar or wind turbines, than to continue to buy coal to keep using the coal power plant, never-the-less this has not stopped developing countries from failing to make the change.

Coal power plants are a large source of carbon emissions

Coal power stations could cut coal use, and therefore emissions by 50%

Coal power plants have to be a thing of the past as soon as possible. This is because no matter how efficient they are, they are powered by digging up carbon and releasing it into the air.

However for the time being, there are many coal power stations across the world. Vishwanath Haily Dalvi of the institute of Chemical technology in Mumbai India has been looking at how we could assist this process with the suns energy.

By collecting the suns heat energy, and using this to heat the water, the amount of coal needed is reduced by 50%.

This could therefore be a more economic way of reducing emissions from power generation. Given that coal power emits 0.85 pounds of carbon per kwh (about 380g), cutting this in half would make carbon far cleaner. While this may well be expensive to set up, it might allow coal power plants to operate for a few years longer and therefore be worthwhile, as well as offsetting some of the damage from the large number of coal powered stations being built across countries such as India and China.

Manchin has made millions from coal since joining the senate, and he may be able to block Biden’s plan to halve greenhouse gas emissions

This website was designed to simplify wildlife travel – and we are making progress on this (slowly- terrible timing, given the epidemic), however without significant and rapid cuts to the worlds fossil fuel emissions, impacts from global warming will destroy many wildlife habitats so it is of importance.

Climate change is increasingly causing changes in rainfall. This is turning rainforests to savannahs and savannahs to deserts.

Without dealing with climate change, there will be far fewer ecosystems in which to save the wildlife.

This is why the USA is important. At this point the USA emits roughly 16% of the worlds warming gases.

The British government have decided to ban burning coal for electricity one year earlier in 2024

Coal is one of the dirtiest power sources, and increasingly around the world it is recognized that its burning must stop if we are to retain a planet easy to live on.

Later this year, there will be a climate conference held in Glasgow and the British government have been keen to make sure that it moves things forwards – if sea levels rise as much as predicted, life in the UK will change dramatically, not least as the UK could become an archipelago.

China must close 600 coal-fired power plants early to hit their own climate target – but this could save money

China has stated that they will peak their emissions by 2030 and hit carbon neutrality by 2060. These targets are just about acceptable in terms of meeting the human races target of holding temperature raise to 1.5 degrees C.

Foolish attacks on renewable energy – Texas blackouts cannot be blamed on green energy

With incredibly cold weather hitting Texas (for instance the beach is covered in snow), Fox News has been making a big thing of the fact that some of the wind turbines are not turning supposedly because they froze – and that this is the cause of the blackouts.

This is factually incorrect. According to data from the Texas government wind turbine shutdowns accounted for less than 13% of the total outage. A bigger problem is freezing of oil and gas equipment throughout the state.
