Meaningless metrics, episode umpteen

We got some pretty confusing information in the last few weeks. On the one hand, we got to hear that there is no long term vision for energy policy by our politicians and that this leads to the increased risk of having blackouts in winter. We were in this situation before. In the last several years we got to hear in autumn that we risk having blackouts in the next winter.

On the other hand, there was the communication that Belgium is doing just fine and is even at the top when it comes to energy policy! An example of this is a tweet from Bart Tommelein (Flemish Minister of Energy), reacting to the claim that our politicians have no long term vision on energy (translated from Dutch):

The best interconnected country in Europe, 2nd country per km2 for solar energy, 3th country in Europe per km2 for wind energy and pioneer in offshore wind. It is really not that bad. But these nuclear power plants surely need to be replaced.

Which is of course a completely meaningless answer. Even if we assume that this energy-per-km2 metric is somehow meaningful, solar and wind will not help us much in winter. Solar is not available at peak demand and wind is not reliable enough to keep us from blackouts.

It was however the claim that we are in second and third position that caught my attention. Initially, I assumed it was the same (meaningless) metric he used in the beginning of this year. Back then in January, he claimed that Belgium was in third position when it comes to solar energy per km2 and the fourth position when it comes to wind energy. Back then, it became clear that he meant that we were among the best in consumption of solar/wind energy per area (in MWh/km2).

In that post, I already mentioned that this is a meaningless metric since it depends on the area and population density of a certain country. Belgium, being a small and densely populated country, will always being in the advantage when it comes to energy consumption per area. Not just solar or wind, but any energy source.

Compare this with the recent tweet that states that we now are in second position when it comes to “solar energy” and third when it comes to “wind energy” in Europe (EU?). Hey, did we advance one position for solar as well as wind in the last eight to nine months?

Solar and wind power through the eyes of an investor

It is the time of the year again. Autumn had just started and the media was flooded with stories about possible power failures this winter. Under the current circumstances a power failure seems rather plausible. Nuclear power delivers 50-60% of our electricity and six of the seven nuclear reactors will be scheduled for maintenance this winter. This could become a real issue in the coming months.

The reason that we are in such a pickle right now is because the last seven governments had no strategic energy policy vision. The initial decision to phase out nuclear power was taken in 2003, but until now there are no concrete plans to actually replace it with something else. Okay, maybe that is not entirely true: enormous investments were made in solar and wind power. Maybe that was just the plan, replacing nuclear with solar and wind power? The problem is that these investments will not help us with the current problem. Production of solar energy is limited during winter and it is even non-existing during peak hours. Wind power is intermittent and there is no guarantee whatsoever that it will be available when needed.

There are however people who don’t agree and claim that we now should invest even more in renewable energy. One of them is Marc-Philippe Botte who works for an investment company in renewable energy and wrote an opinion piece (Dutch) published on the website of our Flemish Radio and Television (VRT) in which he defends more investments in solar and wind energy.
