The Netherlands is an oil producing nation (or "only an energy poor country would build cycle paths")

A few days ago we went on a family outing to one of the places where Vincent van Gogh lived in Drenthe. It was really a very nice place to visit, and will be an option for our cycling holiday routes this year. While in the area I also took a detour to look at something altogether more industrial.

Many people don't realise that the Netherlands is an oil producing nation. From the 1940s until 1996, oil was produced in this area of the Netherlands. Many pumpjacks still stand as a memory of this time, but the only one I've seen running is that in the video (it's for tourists and doesn't still produce oil). I suspect that Google's Street View doesn't include images of cyclists riding on cycle paths past oil pumps in many other places.



It's another of those myths and excuses - that only a country with no natural resources, without oil and without a car industry would support cycling. However, here's a nation which started supporting cycling right at the time when its oil production was highest.

While the pumpjacks (jaknikkers in Dutch) no longer operate, oil is now being produced in this country again. There's a new technique, involving pumping steam underground which comes back up with oil and gas. The gas is burnt in a power station which contributes to the local electricity supply as well as generating more steam.

Oil is flowing out of the ground in the Netherlands right
now through these pipes.
You may have guessed already that oil isn't really "my thing". I'd like to see less of it being burnt. However, I find the technology pretty impressive. These pipes are amongst those through which the steam and oil flows at present.

Assen is where the headquarters of NAM are based. That's the Nederlandse Aardolie Maatschappij - Dutch Oil Company. It's not a particularly famous company in itself, but it's a joint venture between Royal Dutch Shell (itself a Dutch company, of course and one of the largest employers in the Netherlands) and ExxonMobil - two companies which are known around the world.

And it's not only oil. Some readers may have heard of the Groningen Gas Field. The largest deposit of natural gas in Europe is right beneath our feet here, and pumping stations for gas are distributed around the local landscape, pumping from both this large field and several smaller ones. These stations are small and only really noticed if you look for them. One of them is about half a kilometre from our home. I cycle past it quite regularly, as do thousands of other people:



Two more videos about local oil production:




Another pump, this time outside the NAM building in Assen. NAM is one of the largest employers in this city:

Related blog posts have shown how the cost of running a car in different countries is not related strongly to the cycling rate, nor indeed to how easy it is to afford to buy a car. Contrary to many opinions expressed in other countries, The Netherlands really has not pursued anti-car policies.


I mentioned a car industry back a bit in this post. They don't make cars any more, but surely most people have heard of DAF trucks. In the last week, proposals to increase the speed at which you can drive, and thus burn more fuel, have been raised in both the Netherlands and the UK have this week. Jaknikkers still operate just across the border in Germany.

Petrol price vs. cycling rate for a range of countries

Note that even though this is almost flat between Great Britain and the Netherlands, this is the best case graph for people who think there's a correlation between car fuel price and cycling. This is because this graph concerns only the price of petrol.  If you compare diesel prices then it doesn, those are somewhat lower in the Netherlands vs. other countries. Diesel costs less here than in the UK, for instance and perhaps unsurprisingly, diesel cars are common in the Netherlands.
One of those myths that won't die is that the Netherlands has a high rate of cycling because the price of petrol ("gas" to Americans, "benzine" in The Netherlands) is high. This seems particularly to be suggested by Americans, because the price of petrol in their country is so low, and so is the cycling rate.

However, I don't believe this to be the case. If you remove the USA, and Australia to a lesser extent, many other countries have very similar petrol prices, but markedly different rates of cycling.

The graph shows the rate of cycling as a percentage of journeys in several countries in the world, plotted along with the January 2011 prices for petrol.

There are three areas of this graph which show a story.

On the left you can consider the USA, Australia and Great Britain. All three of these countries have a cycling rate of around 1%, but the petrol prices are spread widely - between 60 cents and €1.47 per litre.

You can then consider the largest part of the graph, Great Britain through to Finland. In all of these countries except Austria and Switzerland, the petrol price is very similar: between €1.40 and €1.48 per litre. However, the cycling rates vary across nearly the whole spectrum, 1% of journeys at the low end and 11% of journeys at the high end. The two end positions are taken by Great Britain with petrol at €1.47 per litre and Finland where petrol costs €1.48 per litre.

Lastly, take a look at the top three: Finland, Denmark and the Netherlands. If you look hard enough here, then you can see an upward trend in both petrol price and cycling rate. However, petrol in the Netherlands is actually only 11% more expensive than Finland (€1.62 vs. €1.48) while the cycling rate is 2.5 times as high (27% vs. 11% of journeys).

But what about diesel ?
But actually, this doesn't tell the whole story. Because we've considered only petrol and not diesel, we've simplified the issue. When I last covered this, I noted that while petrol was more expensive in the Netherlands than in the UK, diesel was 14% cheaper in the Netherlands than in the UK. Considering both petrol and diesel together, the price of fuel is actually more equal between nations than it appears on my graph. For the driver of a diesel engined car (roughly half of new cars sold in Europe run on diesel), the fuel to run it is actually cheaper in the Netherlands than in Britain - yet these two countries span the widest range possible of cycling rates.

I think it's fair to say that there's no real relationship shown here between the price of fuel for cars and the cycling rate. Even when fuel for cars is expensive and congestion results in journeys being slow and inconvenient, people will continue to want to drive if driving remains the least bad option.

The cost of taxation and insurance are also not factors which make driving more expensive in the Netherlands. Insurance for new drivers in particular is much cheaper in the Netherlands than in the UK.

Many myths and excuses exist for why the cycling rate in other countries is lower. The only thing which really explains why the Netherlands stands out so far above other countries is that the experience of cycling is so different. In the Netherlands, cycling takes place away from the threat of motor vehicles on good quality cycle paths and roads which prioritize cyclists. Never is it necessary to take on busy motorized traffic by bike, or even to ride up the side of rows of stationery vehicles. This leads to an outstanding level of subjective safety, and as a result all types of people cycle.

To see the policies, infrastructure and campaigning which have lead to the Netherlands having both the world's highest cycling rate and also the world's safest cyclists, click on what works.

Fuel is actually free of charge for car commuters in the Netherlands
Because the Dutch government encourages businesses to pay their staff 19 c per km free of tax for commutes, the cost of petrol / diesel is actually zero or can even be negative for most car commuters. Yes, people are actually paid to drive in this country.

Cycling rates for the graph are taken from here and here. Prices for petrol (current in January 2011) come from here, here and here.

I covered the same excuse previously. However, it keeps coming up again, so I think it's worth repeating.

A tank full of petrol ("gasoline," if you prefer), and what it means

We bought petrol today. It's quite a novelty for us, as we don't do it very often. The last time we bought petrol was way back on August 27th... 2007.

I've mentioned before that we're not really all that enthusiastic about driving, but today we made a short journey in our car and needed to fill up the tank.

It made me think: what exactly have we bought today ? Our tank full of fuel came to a bit more than 36 and a half litres. 36.5 l of petrol weighs about 26 kg. Burning that one tank full of petrol will put about 84 kg, a little more than my own weight, of CO2 into the air. That's the effect from just one tank full of petrol, which according to the manufacturer is supposed to be enough to drive around 500 km.

Petrol is amazing stuff. It has an energy content of 9.7 kWh per litre, so today we bought 355 kWh of energy for our 53 euros. The car consumes about 0.7 kWh produces 0.17 kg of CO2 per km driven.

A few years back, someone who set a world record by cycling over 1000 km in 24 hours calculated that his average power output was about 115 W for the entire 24 hours. That's someone at the absolute peak of what is possible, and his body generated about 2.7 kWh over a 24 hour period.

In light of this, I think it's reasonable to say that an averagely strong person doing an 8 hour shift at a physically demanding job would expend no more than 1 kWh per day at work, so we could say that in our tank full of petrol we've bought the equivalent of someone working hard nearly every day for an entire year, including weekends and almost all holidays. This cost just 53 euros. That really is a bargain.

Car manufacturers put a lot of effort into insinuating otherwise, but cars are actually quite amazingly inefficient. It seems no-one is really all that interested in making them any more efficient. Petrol provides an awesome amount of energy for a remarkably small cost, and pushing gently on the accelerator makes a car zoom along quite nicely. Anyone who's ever pushed a car any distance knows that there is nothing particularly efficient about it.

There is much hype over electric cars, even though they do little more than to shift the source of the output of that CO2 elsewhere. Many power stations are still coal power stations. In fact, many new coal power stations are still being built, all around the world.

When you burn coal at a power station you get only about 2 kWh of energy per kg of coal burnt. If instead of filling up a petrol car today we had charged batteries of an electric car with the same amount of energy by using electricity generated by coal, it would have required the burning of no less than 177 kg of coal, producing a whopping 518 kg of CO2 in the process. That's over 6 times the amount produced by burning petrol directly in a car. An equivalent electric car therefore would still consume about 0.7 kWh but produce over 1 kg of CO2 per km driven. That's being quite generous, as you never get so much energy out of a battery as you put into it when you charge it. With NiMH batteries, for instance, you get back out only about 2/3rds of the energy you put in - under ideal conditions.

Electric bicycles are also not so innocent as many people think. According to this pro electric bike website it costs 1.8 kWh in electricity to charge an electric bike battery for a 20 mile (32 km) range. That's nearly 1 kg of coal per charge. Even with their figures, which like mine for electric cars ignore the problem of inefficiency of rechargeable batteries, this indicates that an electric assisted bicycle, powered by electricity from coal, consumes about 0.05 kWh and produces about 0.08 kg of CO2 per km ridden.

Yes, so electric bikes, if charged by electricity generated by coal (in Australia, for instance, 80% of electricity comes from coal, and the majority of the rest from other fossil fuels), have a CO2 output per km which is only about half that of an average car with one occupant.

Public transport isn't all that much better either. The average bus occupancy in the UK is only about 9 people. Due to this, figures you can calculate for overall efficiency for the entire bus network are actually remarkably similar to those for single occupancy cars.

The same happens with trains. Only if you assume that electric trains take all their electricity from carbon neutral sources do they look particularly good. High speed trains are remarkably close in emissions to jet aircraft.

Here's a comparison of different passenger transport modes in the US. It doesn't much matter than it says BTU instead of kWh that I've been using. 3413 BTU are equivalent to 1 kWh, so divide these figures by 3413 to get equivalent figures to my calculations above:

As you can see, changing from one of these modes to another is really only about making a small change. Anyone who tells you that one mode of powered transport is incredibly more efficient than another is either selling you something, or is misinformed. However, it's big business (much like oil is) and there are plenty of people with a vested interest in trying to convince you that their motorised car replacement can change the world.

Lots of things are described as "green" but few genuinely are. There is a truly "green" alternative to these modes of transport. It's called a bicycle. No fuel is burnt. No CO2 emissions result. You do have to eat, however from what I've seen, people who drive don't eat any less than people who cycle.

All bicycles are wildly more efficient than powered vehicles. They have to be. Inefficiency makes you tired too quickly (compare pushing a bike with pushing a car). However, some bicycles are still more efficient than others and this makes a huge difference if you need to travel more than short distances. A truly "green" car-replacement for longer journeys looks like this !


The sharp eyed might notice we went to a BP station. I know some people are boycotting them, but frankly it's a waste of time doing so. In my opinion there is very little to choose between oil companies. They're all doing their best to make as much profit as possible from extracting oil from wherever they can get it, and they are all responsible for spills. BP was simply unlucky enough to have had their disaster where it was widely seen and reported upon. Boycotting one chain won't do any good. What really needs to happen is for people to appreciate what an amazing resource both oil and coal are, and to consume less of them.
