Alquilando eléctrico en Palma

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.

The flight “dilemma”

As an international sales manager I have to travel within Europe and Africa regularly… This means a lot of air travel.

So, the dilemma I face is;

While I work to make SDG7 a reality by making grids smarter and greener, at the same time I have a huge carbon footprint by flights.

I know many other people have this “flight dilemma”, do you?

This issue is also related to SDG13 (Urgent action to combat climate change).* How? Sigue leyendo

Sailing 100% renewable

You might have read an old post on electric boats and sea energy harvesting before. I described then, electrifying boat transport as one of the ways to make islands 100% renewable.

Electric sailboats have a lot of sense, and are becoming more and more popular. It’s a fantastic sensation to sail, without the sound of a motor, and for many of us, turning the diesel engine on is to be avoided as much as possible. Moreover, even when the engine is only used for a little time, we strongly feel the pollution.

Precisely because for a sailboat the engine is not used that much, having electric propulsion and battery storage is very reasonable. It can be charged at the normal port outlet, regenerating while sailing, or with a small wind generator and solar panels. Compared to the need of refueling at a port gas-station, the convenience is increased greatly, and also the cost to the owner.

Maintenance of an electric motor is simpler because of less moving parts, the size of the motor is reduced, and the battery can be placed as ballast, incorporated in the hull. Sailboats already have batteries and often the motors have to run just to charge them. By increasing the size of the batteries and having renewable charging (solar/wind), this is automatically taken care of.

Besides, the performance is increased, having more torque at lower rpm, and electric motors are more efficient that the internal combustion counterparts.

Finally, regarding the noise, see this video comparing the diesel engines to electric. Together with the smoke/pollution, this is the most dramatic difference.

In summary, it will amaze me if in 5 or ten years all 95% of all new sailboats are electric. And I hope to sail on one of those soon.

If Energythaca were an island, sailing there would be on a sailboat. That was the image on my first post on the blog.

I guess it is an appropriate post arriving from vacations…

Not so sustainable, after all?

Finally sold my car!

Yes, I was considering to buy an EV, as I discussed in the post “To EV or not to EV”. But, for the moment I just sold my car and will try to be “car-less person”. At the end of the day, using public transport, car-sharing (we now have car2go in Madrid and it works great) and the bike is clearly more sustainable than owning any vehicle. (Well, and also borrowing my wife’s car sometimes…)

But: I sold it. Which means my 15-year-old diesel guzzling 7-series BMW will still be consuming +15 l/100 km and emitting lots of particles and CO2 pollution. Depending on the distance the new owner will drive, it might be more ecological than him buying a new, more efficient, one. That’s because of increased asset utilization and vehicle construction sunken emissions. However, it might be that the most ecological and sustainable would be  Sigue leyendo

Calm and assertive energy. Power in repose.

This post is on other type of energy; The energy, and power, of individuals and the importance of “managing” or “handling” it, it’s about personal energy efficiency and leadership.

Curious as it may seem, two of the books I read recently have a similarity on the subject that I would like to explain here…

One is “Bushido, the soul of Japan“, the other “El encantador de perros” (César’s Way) from César Millan, known from TV as “the dog whisperer”. The first book shows (apart from many other themes) what ethical leadership means in Japanese tradition and chivalry. The second book, what leadership means for dogs and ultimately in nature.
In Bushido, here is a quote I specially liked, on how politeness, etiquette and elegance is understood as mastery of spirit and power in repose:

“…But they all united in the ultimate essential, and this was put by a great exponent of the best known school of etiquette, the Ogasawara, in the following terms: “The end of all etiquette is to so cultivate your mind that even when you are quietly seated, not the roughest ruffian can dare make onset on your person.” It means, in other words, that by constant exercise in correct manners, one brings all the parts and faculties of his body into perfect order and into such harmony with itself and its environment as to express the mastery of spirit over the flesh. What a new and deep significance the French word bienseance comes thus to contain! If the premise is true that gracefulness means economy of force, then it follows as a logical sequence that a constant practice of graceful deportment must bring with it a reserve and storage of force. Fine manners, therefore, mean power in repose…”

Bike immortality, efficiency that never dies

This post shows my new taste for classic bikes… and is also a mix of energy efficiency advocacy and touristic scenery I hope you will like!

Living in Sweden for the last month and a half, I was amazed by the rich quantity…

Bikes in Vasteras Centre

Bikes parked in Vasteras Centre

…and the colourful variety of bicycles around.

I’m not saying nothing new if I highlight the multiple benefits of bicycles for the cities, and for the individuals… so i’ll skip that.

 

What I want to highlight is the immortality of bikes. The older the bike, the more efficient is the “asset utilization”, and higher the return, let’s call it MROEI (mobility return on energy invested). And as long as the frame is fine, by changing tires and brake-pads, a bike can basically live forever. An example, the following picture from a bike almost 70 years old:

To EV or not to EV…

It’ been a while since my last post!

This is a personal view on the question of buying an electric vehicle (EV) or not. Who knows, you might consider the same soon…

It happens I have the “chance” of changing my old third-hand BMW, that despite the “glamour” of the brand, hurts me ecologically and economically with the >10 litres/100 km, that is 1,5 €/10 km, every time I don’t take the metro when commuting… Sigue leyendo
