In 2020, for the first time the UK got more energy from renewable sources than from fossil fuels

In 2020, renewable electricity accounted for 43% of the UK electricity, while fossil fuels accounted for just 38%. The remaining generation came from nuclear. Unfortunately, that proportion was reversed in 2021.

Never-the-less the British prime minister announced in October at the Conservative conference, that the aim is to reach 100% renewable electricity by 2035 (I would suggest that they need to decide if nuclear is a green generation or not – I would suggest it is, but it should therefore be included in the figures, in the long-term it is not likely to be needed, we should be able to generate all our electricity from solar and wind).

It is encouraging to think that by 2035 all our electricity will come from green sources. In addition as no ICE cars should be sold after 2030, by 2035 the proportion of clean propulsion should be rapidly moving towards 100%

If you have been lucky enough to have an encounter with wild Boar, like me you will have recognized them as like pigs but different – but …

Wild boar are the wild ancestors of the modern pig. This is why pigs and boar can interbreed – The domestication occurred in Europe, but started about 9,000 years ago, about 3000 years after we started farming crops. It appears to have happened slowly over time, not all at once as some other domestication moves have been. It is thought that this process started in Turkey, and a couple of millennia later in China. There is some evidence that it also occurred elsewhere in Europe.

The modern pig appears to be descended from a variety of different species of wild boar, suggesting a certain amount of mixing of the different domesticated pigs. It is also clear that human preference had a great impact, as very similar pig like animals appeared in several different parts of the world independently.

In the UK, wild boar populations have accidently been created. These have grown fast, and are currently requiring big culls most years. I would like to see some of these boar moved rather than being killed. Forests with wild boar in, are far more healthy with more young saplings naturally sprouting. I believe that we should accept that the boar is back and reintroduce it into every significant area of woodland in existence.

It is true, that they can be dangerous however so can deer. As with all wild animals, provided you do not get too close you should be fine. Now I would argue that natural predators would be the best control on numbers, but I think in the UK we are not there yet.

Tiger doubling aim from 2010 review – Vietnam

In 2011 vietnams population of tigers was estimated at 20. These are of the Indochinese sub species, unfortunately with only around 350 left across all countries it lives in, this sub species could still be lost. It should be noted, that the last photo was in 1997, and it is considered functionally extinct.

Given populations of tigers in nearby countries, if Vietnam improves its forest health the tiger is likely to return on its own in due course.

Unfortunately, there is little more to say about the tiger in Vietnam

It looks like Oil companies are looking at the future beyond oil. They are definitely not all in

While there are still many right-wing networks that deny the truth to global warming – or increasingly admit the world is warming but suggest that humans have nothing to do with this (a hard thing to argue as the only thing that has changed is us and our carbon emissions- and the change is happening faster than anything we can find in the last few million years), fossil fuel companies do not seem to be making the Investments necessary to move their business in the timescale available.

In the UK the Advertising standards agency (ASA) has promised to crack down on green washing

It is disgusting, that despite the science being clear for decades now (and the urgency needed) there is still so many companies that are desperately trying to hang on to their business as normal way of life.

As the world, and customers in particularly are increasingly voting with their feet and moving if a supplier is not being green enough, a lot are continuing to push out false news to try to throw climate change into doubt.

There has been much success on this, however it has run its course. The ASA has announced a regulatory crackdown on ads which seek to mislead on climate change.

Currently, the ASA rules are loose enough to allow significant misleading claims and mistakes to be gotten away with.

Time will tell if they are successful, however it is work long overdue. Much of the incorrect ideas on climate change have been placed in peoples minds on purpose.

Past examples include oil companies bigging up tiny parts of their business in adverts (and failing to mention the vast emissions from the 99% or more of their core business, along with companies like Volkswagen who cheated on emission standards allowing them to get away with far more emissions than they admitted to. Others include Coke who had a big campaign about waste plastic in the oceans – failing to admit that most of this plastic was their fault.

We will have to watch this carefully. Thankfully, in this day and age, there are many different people watching to keep account of what is going on. We must not avert our eyes.

Leading fracking company taken over by green energy group

Fracking is a problem. In many parts of the world (including in the UK) it only emerged as a means of getting oil out of the ground, after we should have stopped doing this.

It is known that most of the known reserves of oil and gas must be left in the ground. it is therefore insane to start a whole new industry extracting oil and gas in new ways.

There was a lot of people saying that if we need oil and gas, why not find it under Britain, but this fails to recognize that oil and gas use is falling fast and needs to fall faster.

If you look at graphs of petrol and diesel over the last few decades, the combination has remained pretty steady. Let demand is expected to fall off a cliff over the next decade.

This is as a result of dual threats, which could undermine most of the market for these damaging fossil fuels.

Firstly, each petrol or diesel car consumes on average about 2.3 tonnes of fuel. This means that each electric car sold reduces demand by 2.3 tonnes per year. Currently only 11% of cars in the UK are electric, but as the government has stated that new fossil fuel car sales will be banned in 2030, this should rise quickly. When surveyed, most drivers say they hope their next car will be electric. If new car sales are banned at this point, it will take a while for all fossil fuel cars to disappear from the roads.

However, there is likely to be an unpleasant feedback loop, where the more electric cars there are on the road, the fewer people want to buy.

In a similar way, fossil fuel free heating methods will replace gas boilers

As the number of consumers of a product reduces the savings from working in large quantities will be lost. This will push up prices for the remaining holdouts -which in turn will push more people to adopt electric alternatives.

By having a green energy company take over a fracking company, these changes are likely to happen as fast as possible. The new owners are not interested in holding on to fracking as long as possible – to the contrary, they will end its use as soon as possible.

This can only be good news in the world

DHL has ordered 12 all electric Alice cargo planes

While there is not yet a battery that can power a passenger jumbo jet, aviation is looking more and more likely to go electric at some point.

The Alice plane is a plane that when carrying passengers can sit around 20. In cargo mode it can fly around 500 miles. It can be flown by a single pilot, and can fly about 1200kg. Travelling at just short of 300 miles per hour, and taking roughly 30 minutes of charging for every hour in the air (it can only stay up for about 100 minutes) it is thought that using these planes will save about 70% of the cost.

Also, being simpler engines with far fewer moving parts, the planes are expected to have higher reliability and lower costs for maintenance.

Even more exciting, these ranges are doable on current batteries. As there is huge amounts of money going into battery research it is highly likely that in the future, the range of these planes will be able to be increased.

Building new renewable power generation is cheaper than continuing to burn fossil fuels

For decades, many in the fossil fuel industry and plenty of politicians argued that we cannot move to renewables unless they are cheaper than fossil fuels. Now of course this ignores the fact that they have been for decades if we made fossil fuel users pay all the cost of their use (clean-up, health problems and others).

However, a new report shows that across much of the world, it is cheaper to abandon coal and gas power stations and replace them with renewables – and then run them, than it is to keep using the coal or gas PowerStation.

Tiger doubling aim from 2010 review: Bangladesh

It appears that there are only 2 different areas of Bangladesh which still hosts tigers. These include the Sundarbans, an area of mangrove lying between India and Bangladesh and the Chittagong Hills Tract where photographic proof of a tiger has been taken. Unfortunately, though there are tigers in the Chittagong hills tract, it is unlikely going to be more than a few.

While not the habitat people think of, tigers are clearly doing alright in the Sundarbans. The habitat clearly has space for more, but with humans incursions it may never grow much.

There is still some argument about how many tigers call the Sundarbans home. 114 tigers were identified, however as this survey only looked at about 16% of the forest it is reasonable to presume there are more. If all areas of the Sundarbans have similar densities of Tigers, we can estimate the whole population at about 700. Assuming this is prime habitat, the original number of 400-500 seems reasonable.

My judgement is that the tiger population has grown. I suspect that it has not doubled, but it has increased. I suspect that there is still significant poaching, but with continued efforts these tigers could recover.
