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

Capacity first?

…then Reliability, then Efficiency?

Developing an electrical network is a question of priorities. As is developing anything I guess… Which priorities do you think are most important?

You probably agree that the first step in building an electrical system is bringing access to electricity to most of the population, right?

Capacity to efficiency

This might seem solved, but in reality, access to electricity is still far from being universal. Still 1,2 billion people don’t have access to electricity. It’s in fact part of sustainable development goal 7, and, actually, the road to SDG7 is the road to Energythaca.

While building additional lines and power generation units to solve access to electricity, the values of reliability and efficiency are normally not on the top of mind for system planning. What if access to electricity is provided by renewable microgrids, would values like reliability and energy efficiency be achieved at the same time? Sigue leyendo

Why I supported GravityLight (twice)

The concept of the GravityLight is simple and yet very innovative. It consists in a light powered by gravity, it is charged by lifting a weight and letting its descent run the generator and the light.

Of course, it is only possible now thanks to the LED lights and other efficiency gains. With old light bulbs, the duration of the same concept would be ridicule, but now, a simple lift of 2-3 seconds can provide for almost 30 minutes of light.

The running costs are null, and compared to the alternative of kerosene lamps, the impact is enormous in reducing costs, environmental impact, as well as reducing fire risks and negative consequences of smoke on the health of the users….
