Este verano he dado el salto a alquilar coche eléctrico (un BMW i3) para las vacaciones, y aquí cuento el resultado;
Cuánto más me ha costado?
100 € más de precio de alquiler para una semana. De entrada cuesta pagarlo, pero bueno… (especialmente cuando tienes una tarifa buena como la que tiene negociada mi empresa y puedo disfrutar para viajes personales…)
Ha valido la pena?
Sí, por la experiencia de conducción, la sensación de sostenibilidad, pero también económicamente;
Estos 100€ me habrían permitido rodar aprox 1000 km con la alternativa de combustible (Renault Captur).
No he rodado tanto, pero casi, porque el trayecto Aeropuerto de Palma-Costa de los Pinos lo he hecho 3 veces, además de unos 30 km diarios. La electricidad de carga me ha salido gratis porque estaba incluida en la casa de alquiler y en la carga rápida que hice 2 veces.

Do you think islands can benefit from the use of Electric Vehicles?
It’s quite reasonable to agree on the benefits.
Because of the limited distances, because of the availability of renewables, lack of local fuels and high energy dependence, and because of the environmental impact, electric mobility apparently fits there like a glove.
Besides, resiliency to face weather events by storing energy in the vehicle, and reducing peak electrical demand on normal conditions seem to be economically beneficial.
I explained to a friend this week my concept of “battery gap”.
He thinks batteries will not “be enough”, are “too far away” and “too expensive” for grid energy storage… Well, we’ve heard that old story before.
We heard that old belief that solar energy would never be competitive or only represent a small portion of energy generation, right? Or the one that grids had an inherent limit for absorbing renewable power (yes, some people once said it was 15%) Or that to reach a high degree of renewable penetration, the land use would not leave space to grow food… And such.
Since April this year, the new 2 MW crowdfunded solar park in Spain from Som Energía has been producing power. It is unique because it has no subsidies and because the energy is sold to the retail cooperative, so the price is supplied at cost* to the investors.

I’m proud of having participated in this project. It’s sustainable, doesn’t need subsidies and also a good investment. The funding will be returned with no interest, but the benefit is through the reduced energy costs in the retail monthly invoice.
Living in a flat with little space for solar panels, I find it very difficult and inefficient to install one or a couple of self-consumption solar panels. So this is a natural option, to team-up with other people to own together renewable power generation. And it avoids facing the so-called tax on the sun (discussed some time ago here).
Of course there are other investment options like Yieldcos (I have shares from Saeta Yield myself). Or simply buying 100% renewable electricity from the retailer. But helping build this small project with a cooperative feels closer to owning the plant. And power generation not only owned by big corporations is also positive, as has been the case in Germany. We can say it’s a good example of the sharing economy, too…
What other options do you see to participate as an individual in the energy transition?
*Actual calculation is 36 €/MWh, which means 6 €/MWh below the market before taxes and network charges.
“Baseload” is so much twentieth century… It is a concept widely used when demand was not flexible. When there was an uncontrollable consumption and industries were not adapting their production to availability of abundant energy. When the goal was to have nuclear and other conventional power plants running 24/7.
In the twenty-first century, the demand curve is not going to be flat, but is going to be variable and smartly adapted to supply of renewable energy.

Let’s look at the energy demand to challenge this concept…
The following picture was taken in Casablanca from the Kenzi Tower one month ago. It isn’t the best example, though, for example, in Cairo, it strikes more to the eye.
What do you see?…
Actually, there are approximately 200 TV antennas on the roof-tops. Let’s zoom in a bit:
In this portion, corresponding to one building alone, you have around 25 units.
With the advent of cable television, wireless video streaming and other technology, these antennas could soon become stranded assets in many countries. Imagine how many could be left useless and need recycling. While thinking about asset utilization and the sharing economy, I couldn’t help but think:
