Another foolish article about the superiority of ICE vehicles over Electric

The horrific traffic catastrophe in Virginia in the ice has lead to another foolish article about the supremacy of ICE over electric.

I havent heard of the author Charles Lane but the article is similar to dozens I have read in the past “here is an anecdotal situation that occurred to me, doesnt it show how electric cars are rubbish”.

Vehicles are seen on an icy stretch of Interstate 95 closed as a storm blankets the U.S. region in snow. Are you really better in an ICE vehicle than an electric?

In this situation a 48 mile traffic jam appeared on the interstate 95 in Virginia. A trucker found his cab door being knocked on by a woman who was in an electric car and hadnt enough food or water. They were worried about running out of charge while trying to keep their vehicle warm. With kids in the car they had got out to ask other vehicle drivers for blankets or anything else (outside temperatures were minus 7 degrees).

So why was this a foolish article to write? Essentially the lorry driver is saying, look at this situation where ICE cars were better than electric, therefore no-one should buy electric.

So lets look at this situation.

1 Given an electric car can be charged at home, and an ICE vehicle needs refilling at a fuel station, which is most likely to be near full of fuel in an emergency? Many people do a small top-up every night so keep their car at around 85% permanently, except when going on a long journey. Generally people only refill their tank when it is nearing empty.

2 Electric cars are almost 100% efficient with a heat pump as many of these cars use. A tesla 3 heat pump could keep its inhabitants warm for 36 hours on a full charge. In an ICE car it would entirely depend on how recently it was refilled- depending on the size and efficiency idling fuel usage can be anything from 1 litre an hour in a small car, up to as much as 5 or more in a big car (or a sports car like a dodge viper). A Hyundai Kona uses about 1 litre an hour and has a tank of 38 litres, so would last about a day and a half. Even in big cars the fuel tank is not normally bigger than 70 litres, which would suggest 14 hours,

As such, in actual fact the odds of running out of fuel (charge or gas) in a sticky situation is likely to be far higher in an ICE vehicle. Once in the situation, unless you are in the right car for this rare situation, electric is far more likely to safely keep you warm till the road clears.

Now it is true that should your electric car drain completely to zero, it is more bother to recharge an electric car than it is an ICE vehicle, as the latter merely needs a walk to the nearest petrol station. Why do so many writers grab every chance to take a swipe at electric? Probably because they know that they will be paid well – however as these stories start to look more and more stupid, I think it is going to be harder to find someone to write your hit piece.

The carbon footprint of space exploration- its not as high as you think

There has been much made of the idea that given our need to cut carbon emissions, space flight should go out of the window.

However, would you be surprised to hear that a SpaceX rocket emissions is roughly equivalent to 1 large jet crossing the Atlantic. Given that last year there was an average of roughly 1700 transatlantic flights each day in 2018, that is actually a relatively small amount.

Was Bulb as clean as it claimed? how can we tell?

In the UK (and I am sure in plenty of other countries) as the grid has cleaned, there have been a whole host of firms that have sprung up as a middleman – buying green electricity and providing it to their customers. There is nothing particularly unusual about this – we get our electricity from Octopus on a similar scheme. With many of these firms, they supply the electricity and gas, but often have few holdings themselves.

Octopus is busily investing in all sorts of green electricity generators, but the problem exists that if you do not own any of the electricity generation, then in tough times this can be your undoing.

Now, many of these claim to be fully green, but are not necessarily. The reputable ones match each unit used to a unit of renewable generation that went into the grid (Ofgems renewable energy guarantee of origin REGO). Alongside this, the reputable ones also invest in renewable generation.

So was Bulb as green as it suggested? Well the complaint came from the fact that only 5% of its power came directly from renewable energy projects, the rest was bought on the open markets through the aforementioned REGO. The point is, the electricity grid does not consist of electricity traveling like emails to specific places – it is supplied everywhere jointly by all the producers. This means that provided a supplier is paying for enough green electricity to cover all its customers uses (and has the REGO certificates to prove it) by definition, it is fully green.

Would it be better if the company had some green generation of its own? probably, but provided the scheme works it does not have to. It allows green electrical generation to be used as it is created – by who ever needs it, exactly as our grid is designed.

This problem has arisen because the government allows green electricity and the certificate of it being green to separate people. However, provided the certificates only cover the amount of green electricity that is being created, it is not counted twice it is merely worth more to the creator.

What is wrong with this? If creators of green energy are aware that they can make more money than those burning gas, many will switch. This still does what is needed, and provided green electricity certification is accurate it wont be double counted.

Possibly, the last nail bulbs coffin, was caused by the government setting out plans to make this loophole smaller. These so called pale green energy tariffs – where green energy was not bought directly from a renewable energy project are supposed to be eliminated.

I think the British government needs to be careful here. It is quite possible that in the near future, these providers will not be necessary as all the electricity in the grid will be green. However, for the time being it is worth continuing to offer this premium to green electricity creators and the ability for suppliers to make sure they have covered their promises.

Now in the case of Octopus they are also replanting and rejuvenating a section of the Amazon rainforest to offset any gas emissions. It is currently unfortunately true that it is far cheaper to heat using gas – heat pumps are likely to greatly change this, as they are 300% or greater efficient (in terms of electricity in, and heat out) however for now gas is used. A reforestation scheme can be guaranteed to suck up the carbon it is promised to capture.

Our guaranteed green electricity and offset gas monthly cost is roughly £5 more than the best price on the market, and for us £60 a year to know that our electricity and gas use is not increasing the problems of global warming. Having said that, we are still trying to reduce our use through: Smart devices, added insulation and when we get them installed – solar panels and thermal solar panels. The other advantage with a scheme like this, is it guarantees you a price for you exported electricity – so if you have solar, and are currently not being paid for anything that you export perhaps now is the time to switch. This essentially means that you can use Octopus as a battery.

Do not be mislead, an electric car always has lower emissions than an equivalent combustion engine car

There is a constant argument made by those who like the combustion engine car. They want to add up all the emissions that are released creating the electricity and therefore suggest that the electric car is worse.

This shows that the BMW 3 and tesla 3 are similar sizes, though electric cars tend to be bigger inside

This argument quickly runs into problems: an electric car is so much more efficient that it is irrelavent.

We have made wonderful progress towards cleaning up the grid. Now to finish the job…

Incredible progress has been made over the last couple of decades towards greening our grid. Coal is now supplying a very small percentage of our power, and this is likely to fully disappear in the next few years. Gas is the only remaining fossil fuel on our grid. We mad roughly 28 gigawats of electricity from gas in 2018 (last normal year before epidemic). There are plenty of ways to get this from clean sources

As an example, 1 megawatt of solar panels takes roughly 4 acres, and costs about 1 million pounds. Therefore, 1 gigawatt would take roughly 7 square miles and cost roughly 1 billion. That means to replace 28 gigawatt hours of gas generation with solar, would cost roughly 28 billion. The batteries would cost about 2 billion for a similar quantity. In terms of area, we would need roughly 150 miles, which is roughly 2/3 of all the rooftops of the UK housing stock. If, however, all UK commercial governmental and industrial buildings have their roofs covered in solar panels, this would likely take a great deal of the capacity needed. Even if you assume we need extra for night time power, we can not be talking more than 50 billion.

I am not saying that the government needs to invest this now. However, as gas powerplants do not last more than about 25 years, we can assume that by 2050 all the current ones would be decommissioned. If as each gas powered plant goes offline it was replaced with solar and batteries, the cost would be roughly £1.8 billion a year while a huge cost to many countries, would essentially be a rounding error in the UK.

Will our fight with Covid push the human race to tackle global warming?

Can the human race use the lessons learnt during the Covid epidemic to start addressing climate change as the existential threat that we know it is? Estimates vary as to what the Covid epidemic has cost, but economists estimate roughly $28 Trillion. Now while that sounds huge, it is only about 1/3 of global output annually. Given that Covid has taken place over around 2 years, that means an output reduction of less than 20%.

Now it is true, that governments around the world have spent vast amounts money propping up economies and trying to avoid as much of the pain as possible.

Climate change is predicted to cost about $23 trillion per year by 2050!

In other words, economists are predicting that in 28 years, we will have to find almost the price of fighting Covid – every year (remember that the Covid costs have been spread out over 2 years).

CAN YOU IMAGINE THAT?

We are marching towards a future, where we pay out almost the whole cost of COVID every year, to mitigate the effects of climate change.

Sainsbury has stopped selling all or some beef from Brazil along with 5 others

In Brazil, one of the main drivers of deforestation is for pasture for beef. It is therefore completely foolish for those in developed countries to eat Brazilian beef – if we do, we are paying them to do the world (and therefore us) incalculable harm.

Importantly, these people can wait. If we have a moratorium on grazing on newly deforested land, the land owner can wait a few years or a decade then its value jumps. This move was taken after it became clear that “cattle laundering” was going on.

Cattle laundering means we can no longer tell which meat from Brazil is safe to eat

Should being sued be a sign you are doing the right thing?

Mongabay, one of the best websites about the natural world, has had one of its writers sued. This happened after the reporter in question reported on illegal deforestation by a Peruvian cacao company.

For this company, it appears that this is a decision that they have taken, having sued several other outfits in recent times. The suit has been thrown out. The company had also sued the 4 members of the local environment ministry, including the one which lead the prosecution of the company. This suit has been lost, but the company is appealing.

This sounds like extreme wrong-doing. If you are prosecuted and found guilty, clearly those who prosecuted are right.

Increasingly, companies that are involved in illegal acts will sue anyone who uncovers it – wrongful judgements can move them forwards, and even if not, the court process can keep everyone tied up for years – if anything survives of the forest at the end of that, it is surprising. The judgement for the original crime of destroying forest, was clear and final with 3 sentenced to prison for the “crime of illegal trafficking of timber forest products and aggravated obstruction of justice”. They also had to pay fines of over $4 million.

Unfortunately, despite overwhelming evidence all of the sentences were overturned by the supreme court – freeing the way for the attack on Mongabay. Indeed, 4 days after the original publication a notarized letter arrived requesting the article be corrected – in particular, claiming false claims were made in the article. Mongabay Latam published an article refuting each point in turn. Some of the points were absurd, with the company complaining about the turn deforestation being used – as they had not been found guilty of this. More foolishly, despite forest destruction being deforestation by definition, the website had only quoted one of the officials prosecuting.

This back and forth continued, but suffice to say their arguments are stupid: talking about logging and deforestation are completely interchangeable.

Stupid moves in court must be publicized, as only ridicule and financial loss will force companies like this to behave.

Thankfully, this website is not a big enough thorn to have to face similar suits, but that may come.

Often locals lose their forests against their will, sometimes this balance is corrected

A Papua court ruling, is a win for local governance and against national governments. All over the world, most remaining wildernesses are not devoid of human population to the contrary, most of these areas are inhabited by indigenous people.

What does indigenous people mean? Well in most contexts it means people who arrived and settled before European colonisation. What has become increasingly clear is that the explorers that we learn about are rarely the first humans to arrive in newly discovered countries. Indonesians and Norwegians are both known to have crossed large oceans and settled on newly discovered lands.

Often these native people have lived in harmony in the local ecosystem for thousands of years.

This is why indigenous rights are so important. It is however important that this is done right – indigenous lands becoming places with casinos is not the idea.

In this instance, two palm oil companies sued after their lease was invalidated. The combined area is not small, being bigger than New York city. This clears the way for Indigenous groups who used to live within this area, to reclaim their former lands.

Indonesia has a particularly hard path to walk. Made up of thousands of different islands, with vast areas of rainforests, it is hard for the central government to make good decisions.

We as consumers need to make this easier, by reducing our consumption and therefore requiring less resources
