Wible hace un poco de “trampillas”?

Como ya comentaba en otro post, en Madrid tenemos una oferta completísima de servicios de movilidad.

Al no tener coche, soy muy usuario de todos ellos, transporte público, mobike, zity, emov, wible, bicimad y vtc/taxi (por orden de uso).

Lo que no uso habitualmente son las motos (Muving, acciona, etc) ni los patinetes eléctricos (aunque le pido prestado de vez en cuando el patinete normal a mi hija)

De las opciones de coche, reconozco que intento evitar usar wible, salvo que me quede otra opción muy lejos y no me pueda acercar en bici…

Por qué?

Vacaciones eléctricas en Palma II

El año pasado ya probé a pasar las vacaciones con coche eléctrico y lo contaba aquí.

Por qué?

Por compromiso con la sostenibilidad y por aplicarme el cuento. Además, es divertido ser de los primeros en probarlo.

He repetido este año con Hertz, pero más tiempo (3 semanas en vez de una) y con otro coche (el ZOE, que era más económico de alquilar)

La experiencia ha sido así: Sigue leyendo

Publication: Charging island homes

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.

The research we recently got published in Energy, focuses on the effect of using the vehicle’s energy to charge the home at peak load and charge the vehicle* during valley.

This is what we found out…

NZEB + EV: The decarb combo

Are you aware of these stats?

  1. Buildings account for 40 % of energy consumption and 36 % of energy emissions (EU data)
  2. Road transport accounts for 25 % of energy consumption and 20 % of energy emissions (EU data and EU stats)

Then, what happens when we combine NZEB buildings (net Zero Energy Buildings) with local renewable generation and EVs (Electric Vehicles) charging in these NZEB?

It’s obvious… -> We can decarbonize 65 % of the energy system!* Sigue leyendo

Future surpluses in Energythaca

On one hand, the rise of renewable energy, even before the 100% goal, will bring a surplus of power. This means there will be excess power that is not required in the system. It already is happening and it will be even more so. This power can be stored, but of course, using it directly is more efficient and thus, preferable.

On the other hand, the penetration of robotics and software will change the jobs available for humans, as is in discussion in Davos these days. This means there will also be a surplus of productivity.

Technocratic paradigm and Smart Cities

If you are interested in Smart City technologies and experiences, I strongly recommend the following report from Nesta:

Rethinking Smart Cities From The Ground Up

The proposal is similar to how I suggest to build the Smart Grid: Do it bottom-up, empowering the consumer/citizen. In this case, the report justifies that the highest return is on collaborative technologies that allow the citizens to participate and shape the future of their cities.

As is widely mentioned, there is no smart city without smart citizens. Just like there is no smart grid without a smart consumer. Thus, investing in smart people is absolutely necessary for Sigue leyendo

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
