Whenever these days I tell people – when asked - that I work on renewable energy, they always reply that it is a very actual topic. Indeed, these days everybody seems to know what renewable energy is. However, when I then ask them what they actually know about present renewable energy use, they do not have a good idea of e.g. how much renewable energy we actually use these days (EU ca. 10%; Belgium/Netherlands 3-4%). There is general awareness of renewable energy, but people still have little concrete feeling for it: it seems it is still an abstract topic despite the visibility of wind turbines and solar panels.
A project in Wallonia/Brussels is trying to change this through raising concrete awareness by including the topic of renewable energy in the weather forecast. It cannot become more part of daily life than that!
Every week on Monday the Francophone Belgian TV Channel ‘La Une’ brings in its weather forecast also the ‘renewable energy meteo’ of the previous week. It shows this in three indicators (see picture):
- The first indicator, in blue, shows the ‘solar photovoltaic weather’: it shows which percentage of the electricity use of an average household was generated by the sun for those houses that are equipped with solar panels (a typical set-up of soalr panels is assumed).
- The second, in green, shows the ‘wind energy weather’: it shows how many households have been supplied with electricity generated by the wind turbines in Wallonia. The amount of households is also translated into an actual local town or area of that size.
- The third, in red, shows the ‘solar thermal weather’: it shows which percentage of warm water needs of an average household was generated by the sun for those houses that are equipped with solar water boilers on their roof.
Hopefully this will make people think now and then when looking at the weather: ‘this looks like a good renewable energy day!’
