Goodbye 2010 – welcome 2011

2010

2010

It’s the last day of 2010, time to look back, like I do every year.

On April 14th, 2010, the Iceland vulcano Eyjafjallajökull () erupted, severely disrupting air travel over the northern part of Europe for a week or two. This was inconventient enough for the stranded air travellers, but the contrail-less sky contributed to record yields () of solar power.

On April 20th, the oil exploration platform Deepwater Horizon exploded () while drilling in the Gulf of Mexico, after which unbelievable amounts of crude oil flowed into the sea for three months. Although the disaster received much media attention the mainstream media didn’t ask the question that needed to be asked: why are we drilling for oil in ever more inhospitable places? Unfortunately, it appears that nothing was learned from this disaster because in the Gulf of Mexico things have returned to ‘business as usual‘ ().

If two disasters weren’t enough for one year, on October 14th, 2010 our new cabinet was sworn in ().  Both CDA and VVD don’t have a very good reputation when it comes to sustainability, but to make matters worse  the PVV supports this minority cabinet. The PVV (much more in the foreground than you’d think) came up with unsustainable propositions as the raising of the maximum speed on motorways to 130km/u (), the tearing down () of wind turbines, building more nuclear power plants () and constructing more roads (). Both VVD and CDA made a big dent (in a negative way) in Dutch progress in sustainability by cancelling the SDE-subsidy plan for small scale decentral solar power systems. It’s clear that mr. Rutte’s team is not very interested in sustainability. “Our new prime minister is illiterate in the area of sustainability”, says () (blz. 10/11) Jeroen van den Bergh of the VU university. The coalition agreement () clearly shows that, unfortunately. We are making great great strides – backwards.

In 2010 the so-called ‘smart meter’ () was back in the news again I’m sure we’re going to here more about that in 2011.

2010 also was the year in which the Dutch Consumers’ Association (DA) discovered solar power, but unfortunately they didn’t do their research. Both in the articles of May () and December () 2010 the DA published articles with several incorrect facts about solar power. The tone of both articles is very negative and basically implore the reader to not install solar panels. Based on a few untruths several very negative assumptions are done. I can’t understand why articles of this low quality are published by an organisation which boasts about its neutrality.

So there was lots of doom and gloom and the world stage. Fortunately, on a smaller scale, 2010 was an excellent year. First and foremost I got married () on June 25th, 2010. It was a fantastic day in every way, which got even better because our wedding car was a Tesla Roadster ().

In 2010 we installed an extension of 660Wp () of our solar panels. I expect our installation to be really finished now – but you never know, it always keeps itching. :) For me, 2010 also was the year of Plugwise (). I’ve been monitoring the electricity production of our solar panels with Plugwise since the beginning of 2010, and I like it a lot as the system allows me to monitor all five sub-installations from my computer, without having to walk to the attic to read the meter there.

On May 15th, 2010 we had an open door day () under the umbrella of the Solar Days (), and with ten visitors nicely spread throughout the day it was quite succesful.

In 2010 I made three long test drives in the Tazzari Zero (one (), two (), three ()), and a short test drive in a Nissan Leaf (). In September I visited the Ecomobiel () fair about, or so they claimed, sustainable mobility. It was mainly a car fair, but despite that I managed to see some interesting things.

2011

2011

What can we expect in 2011?

One of the things I really want to do in 2011 is to improve the insulation of our house. We’ve had two severe winters in a row now and it’s starting to get expensive. Of course I also find it hard to swallow that we’re using a non-renewable energy source (natural gas in this case) in a very inefficient way. When this is done I will of course write an extensive article with photos and everything.

I hope I can make a longer test drive in a Nissan Leaf in 2011, which should allow me to write a ‘full-size’ article about this car. I also plan to test drive some electric bicycles and electric scooters, which are of course much more sustainable than electric cars. They’re also much cheaper than electric cars and affordable for a much larger group of people.

In June 2011 I celebrate the fifth anniversary of this website. I stil l haven’t decided what I’ll do, exactly, but I’m sure it’ll be a party of sorts.

I expect the Solar Days to be organised in 2011 as well, with its associated open door days. I plan to participate again.

From October 16th to 23rd, 2011 the biannual World Solar Challenge () will be held. I hope to be able to extensively report about the event, like I did on previous occasions. In 2009, the two participating Dutch teams didn’t succeed in finishing in first place, I hope one of them succeeds in doing this in 2011. There were some severe accidents in the 2009 event, might the rules () have been changed for the 2011 event? I’ll create a list of participating teams soon, like I did () for the 2009 event.

The oil price crept upwards in the last quarter of 2010 until it passed the $90 mark. $100 is viewed by many a psychological threshold beyond which oil is ‘too expensive’ and renewable alternatives like sun and wind become more attractive. The predictions about what the oil prices will do in 2011 vary wildly – as they always do. I’m not going to venture a guess. I only hope, as always, that the oil price will maintain it’s steady trajectory upwards, that gives the alternatives the best chance. If the price fluctuates wildly the economy is damaged and nothing will happen because of great uncertainty.

The end of a year is a good time to consider how the website is actually doing, and how it should continue in the coming year. Except for the fact that I should write more I think it’s going fine. The number of visitors is reasonably stable, there is some variation throughout the months but that is to be expected. I expect more visitors in 2011 because of the World Solar Challenge, as that also happened in 2009 and 2007. The nature of the articles I write apparently still appeals to the visitors, so don’t expect any major changes in 2011. “If it works, don’t fix it.” :)

Beyond the foreseeable stuff I’m sure 2011 will have its share of unexpected events, both positive and negative. I’ll do my best to report on the most interesting stuff in positive and balanced way. No matter what happens, I wish everyone the best. I hope for a lot of sunshine and wind so that we can generate a lot of renewable and sustainable energy :)

December 2010 – snow!

Snow on the solar panels

If December 2010 will go into the history books for something it will be the enormous amounts of snow that fell in the Netherlands. All that snow can’t help to have some effect on the performance of our solar panels. On the photo to the right you can see that the snow completely covers all panels and that means that the production is an unsurprising…. 0W.

Through channels like Twitter and e-mail I’ve received the question “should I remove the snow from my panels or not?” many times. My answer is simple: don’t do it, unless you can reach the panels easily and without any danger. It’s December, the days are the shortest of the year, it’s generally overcast and that means that even without snow the yield is extremely low. It’s in no way justifiable to risk your life for (maybe) a few extra kWh.

Because I could reach it from the ground with a broom I did clean the little 100Wp panel above the front door, but as I expected the production was very low.

Production in December 2010, per day

As the Plugwise-graph to the left shows, our panels produced nearly nothing from December 16th onward. On December 24th I cleaned the 100Wp panel but it’s clear that it didn’t amount to much, and that was despite some sunny periods we had that day. For some one who loves solar power like I do that’s hard to swallow but that’s just how it is.

There is also positive news: December 21st is the shortest day of the year and that means that the days are getting longer again. Spring is on the way and our solar panels should start producing more and more as the summer approached. Have patience, nicer weather is on the way!

Insulation

Snow against the rear of the house

Besides snowy December 2010 is also very cold and that means that the central heating is working hard. I can only measure it by the end of the month when I write down the meter readings but I expect a very high natural gas consumption over this month. Together with the cold winter of 2009/2010 this will almost certainly make 2010 a year with a very high natural gas consumption.

It was my plan to have the floor and cavity walls of our house insulated before last autumn and before the heating season, but two large expenditures (our marriage and some expensive maintenance on our roof) made this financially infeasible.

I noticed something a few days ago. The picture to the right shows the snow as it lies against our house on the rear side. The house was recently extended there and it seems to be quite well insulated. It’s clear that the snow piled up against the wall.

Melting snow against the front of the house

On the other side of the house the snow is clearly molten for some distance from the house. The wall on that side is not insulated and it apparently radiates enough heat to melt the snow for a few centimeters.

I really don’t like to see that. Besides the fact that’s it’s simply expensive to heat up the outside world I firmly believe it’s a terrible waste to use a non-renewable energy source like natural gas to melt snow.

As soon as everything has settled down (both the weather and our finances) one of the first things on the agenda is inslulating both the floor and the cavity wall. I hope to be able to show photos of as much snow against the front as against the back of the house next year.

Nissan Leaf short test drive – report

Nissan Leaf

On December 16th, 2010 The New Motion () organised a test-drive day, and they offered me the opportunity to make a short test drive in a Nissan Leaf (), which has been chosen as car of the year () 2011. I was of course very interested in driving this special car, the first car from a major manufacturer to be designed from the ground up as an electric car and not a conversion or adaptation of a fossil car..

The day was divided into slots of about half an hour in which the car could be driven. A these things go on days like this, they were running a bit late by the time it was my turn but that was all right. The weather was very bad that day, it was cold and it rained hard continuously. Unfortunately the weather kept me from taking pictures; I didn’t fancy exposing my camera to the rain for exterior shots and most photos of the interior turned out way too dark. That’s why this article will feature only a few photographs. At about 11:00 it was my turn and together with an employee from The New Motion and an employee from Nissan I braved the rain to run to the car.

Statistics update

November is over, time to close the books. The solar panels produced only 27,1 kWh (12,8 kWh/kWp). That isn’t much but it’s normal for the time of the year. Our electricity consumption over the same period was 88,1 kWh, which is just about average. Over 2010 we have an electricity surplus of about 250 kWh. I expect December to nibble off approximately 60-80 kWh, still leaving us with a negative electricity bill over 2010.

Natural gas consumption was high, especially in the last week. This was no suprise as it was very cold. We burned through 80,1 m³. Our drinkingwater consumption was low with only 3,9 m³. We did unfortunately made quite a few car kilometers, more than 300. At the beginning of the month I drove the Tazzari Zero for a bit (which is electric, so ‘somewhat okay’) but we twice visited friends who live in places which are hard to reach with public transport.

All in all, quite a normal month, for the time of the year. The low yield of solar electricity is never fun to see, but that’s all part of the game :)
