OIL makes the world go round – but for how much longer?

Recently a new exhibition opened at the photo museum Fotografiska here in Stockholm. It’s the Canadian photographer Edward Burtynsky who has spent the last 12 years portraying humanity’s relation to oil and what it does to the planet. He shows the oil fields – from the first one in the US to depleted ones in Azerbaijan – giant highway intersections, graveyards for engines, tires and oil tankers being dismantled by hand in Bangladesh. One year ago he also went to cover the disaster in the Mexican Gulf, when the BP oil drilling rig Deepwater Horizon exploded.

Walking around at the museum I was hit by how massively our love story with this energy source affects the planet on all possible ways. But there are plenty of voices saying that this can’t go on forever. One of them is the physics professor Kjell Aleklett, Sweden’s own “Mr Peak Oil” who has spent the last 16 years doing research about Peak Oil and who is indefatigable repeating the message that oil is in fact a limitied resource.

Peak Oil means that when half the oil available on Earth has been pumped up and used (with production at its peak), the extraction of new oil will inevitably fall. According to Kjell Aleklett we passed this peak already in 2006, while our demand for oil just keeps growing. During the last decade he has been talking about the urgency of adapting to a future with less oil, targeting business leaders and politicians. Because adapting, says Kjell Aleklett, won’t happen fast. We need about 20 years to get rid of our oil dependance.

In Sweden our electricity comes from nuclear energy. Most people no longer heat their houses with oil. But – Kjell Aleklett points out – we still fuel most of our vehicles with oil, transporting people and goods that we would have a hard time living without. Since 1970 that oil consumption has gone up by 83 percent. So there’s a lot to do in Sweden too.

Tomorrow Kjell Aleklett will speak about Peak Oil in the European Parliament. In a debate article in one of Sweden’s largest morning papers a few weeks ago he wrote “I hope it will contribute to a review of the European Union’s energy policies. In ten years it will be too late.”

Japanese disasters and Swedish (nuclear) reactions

This last week the big subject of conversation in Sweden is (as I suppose in most parts of the world) the terrible events in Japan. That natural disasters such as earthquakes and tsunamis can lead to man-involved disasters like nuclear meltdowns is something we all know, but normally prefer not to think too much about. When it finally happens, it reminds us about the risks we actually take.

In Sweden the developments in Japan have led to a fervent debate about nuclear energy in tv news shows, on the Internet and in newspapers. The Swedish Radiation Safety Authority has reinforced its preparedness and answers all kinds of questions about nuclear energy on their web page.

In the debate, some point out that what has happened in Japan couldn’t happen here since Sweden geological conditions are quite different. Others argue that the problem is rather the nuclear energy’s lack of resilience against unexpected events. Although we might not have any earthquakes here, other things can happen, an what actually caused the meltdown in the Japanese reactors wasn’t the earthquake itself, or even the tsunami, but a power failure.

Nuclear energy has been a debated issue in Sweden for a long time now. In 1980 we had a referendum about nuclear energy, that ended in a decision to phase it out. But last year this was changed. Now new reactors can be built in Sweden as long as the total amount don’t exceed 10 reactors.

Another issue of debate when it comes to nuclear power is the issue of terminal storage of the used nuclear fuel. Yesterday the Swedish Nuclear Fuel and Waste Management Company SKB, which is in charge of taking care of the radioactive residues, handed in an application for making a final repository for spent fuel in Forsmark in the East of Sweden [map] where it should be stored for 100 000 years. At the same time SKB’s office was targeted by an action from Greenpeace, claiming that there are still a lot of uncertainties of for example how the copper containers will stand the test of time. A corrosion expert from the Royal Institute of Technology KTH has earlier stated that there are risks of these capsules collapsing within 1000 years.

Vertical farming for future cities

Could vertical greenhouses help cities meet future food challenges? Image: Plantagon International.

“Far from lagom” (lagom meaning something like “just enough”, or moderate) is the slogan of the municipality of Botkyrka in the outskirts of Stockholm. So when they started thinking about urban food safety the idea that came up was also far from lagom: A sphere-shaped vertical greenhouse, about the size of the Stockholm landmark Globen.

But why a giant glass ball filled with vegetables? United Nations expects that the world’s cultivable area won’t be enough to feed a growing global population. At the same time an increasing part of this population lives in cities and transports will be more expensive because of a peaking oil production, so why not produce the food directly where it’s needed?

According to Hans Hassle, CEO of the company Plantagon that makes the sphere greenhouse, this type of greenhouse can get up to four times as productive as an ordinary one, providing as much as ten times the cultivable area compared to the surface needed for the building itself.

Now the Swedish Delegation for Sustainable Cities have granted the Plantagon project 150 000 SEK (about 21 500 USD) to investigate if a greenhouse like this might be something for Botkyrka. The municipality sees it as a way of renewing the million programmes in this area. So who knows, maybe we’ll have a new – food producing – landmark in Stockholm in a few years?

Oil vs muscle power

Kjell-Aleklett

Kjel Aleklett talking about future energy challenges.

Yesterday Tällberg Foundation arranged something they called “A Day For the Future” at Skeppsholmen, which is one of the islands in central Stockholm.
Having spent the weekend trying to suck the last sweet nectar out of this wonderful summer at Möja, another island further out in the archipelago, I arrived just in time to hear the “peak oil guru” professor Kjell Aleklett and his colleagues from Uppsala University talk about our energy future.

The theories about exactly when peak oil will happen differs, but the fact that oil is a limited resource and that we won’t have cheap and easily accessible oil forever is something that humanity will have to deal with, whether we like it or not. The question is just how.
Right now more than 80 percent of the world’s energy mix comes from fossil fuels.
Kersti Johansson, a researcher at Aleklett’s institution held a very interesting talk about the possibility to replace the fossil fuels that now are used for transportation with bio energy coming from agricultural crops or spill. Her calculations show that it will be very difficult, unless we want to grow crops for energy production instead of for food.

Not far from the museum library where the Peak Oil seminar was held I found something that makes it even more obvious what a lot of energy we use in our daily life. Matlinah Omiti from the Royal Institute of Technology showed me the “Smoothie Bike” that she has constructed. By peddalling you power a blender and mix your own delicious fruit drink. I tried it, and actually it doesn’t take a lot of sweat. By increasing the resistance you could make other things work with your muscle power, Matlinah explained to me. You can for example light up one light bulb or a wall of LED lamps, and you could grind coffe. But when it comes to boiling the water for that coffee, you will fail, because boiling water requires so much energy!

Last year the BBC actually made a very funny show on this subject, connecting the energy grid of a house where a family was living their “ordinary” life to a hall with cyclist, powering the home with excercise bikes. 78 frantically pedalling cyclists were needed in order for the father of the house to take a shower…
Maybe we should start using gym bikes a bit more efficiently?

Music against gas drilling

The Urkult festival wasn’t the only big music event this past weekend. In the old alum works area of the Christinehof Ecopark in Skåne in the south of Sweden artists filled the whole Saturday with music, in a manifestation against the planned extraction of fossil gas in Skåne.
Ever since the energy company Shell started their test drillings in three of the county’s municipalities, protests have been growing.
According to the protest network “Heaven or sHell”, drilling for gas would mean great risks for the groundwater, but also affect air quality, the landscape and its inhabitants.

Recently European statistics showed that Sweden is leading the European

league when it comes to our share of renewable energy compared to total energy consumption. This is much thanks to our big rivers providing us with hydropower enough to cover about half of the country’s electricity needs. But “to invest in fossil energy in 2010 instead of in environmentally friendly and sustainable alternatives is grave”, the anti-gas drilling network writes on its web site.

One of the big discussions about this project has circled around the choice of words. While the drilling company talks about “natural gas” and claims that this gas leads to less emissions than burning coal and oil. Activists, on their hand, underscore that the gas is still a fossil fuel, contributing to global warming, and point out that few people actually know that natural gas and fossil gas is the same thing.

Another thing largely discussed is the current mineral law in Sweden, which does not give the local municipality a veto right when it comes to gas or oil extraction, which is the case with new wind power plants or uranium extraction. This is expected to be an issue for the coming elections.

At the moment Shell is waiting for the result of the test drillings before deciding whether or not to apply for a permit to extract gas. That decision will probably be taken around the end of this year.
