The Waste of the Past








“If I had asked people what they wanted, they would have told me faster horses”

– Henry Ford

The waste and refuse of an era are associated with the dominant technology. That is, the waste of the past is not the same as the waste of the present and, rest assured, the waste of the future will have new characteristics that today are not analyzed in great depth. With this in mind, this week we open a series of three installments to analyze the waste, refuse and residues related to energy in the past, present and future.

To speak of the past, we will not go back to the ice age, but to the zenith of the energy model prior to the massification of internal combustion automobiles, between the end of the nineteenth century and the beginning of the twentieth century, when transportation powered by the muscle of animals dominated, particularly by horses.

The main source of energy of this means of transportation was, precisely, food and, of course, it required maintenance and particular spare parts, for example, the changing of horseshoes, medicine, water and an appropriate place for rest. As you can imagine, the main waste of that transportation system was the manure and urine of the horses that fell directly onto the streets and, of course, their corpses when they passed to a better life.

It is estimated that in New York more than 600 liters of urine and more than three tons of manure were poured per day. Additionally, each year more than 15,000 horse corpses were discarded per day, which represented a replacement rate of between 15% and 20% per year. In other words, demand was growing and so was the need to raise more horses.

This situation generated jobs and entrepreneurs did business. For example, the excess of urine required that the streets be washed several times a day and for this, carts were created that transported water with this function and government workers were in charge of washing the streets. For their part, organized manure collectors and depots appeared who charged for lifting and disposing of the waste. More than 20,000 horses and mules were used in New York for the tasks of collection and disposal of waste and street washing.

However, this mobility model also generated damage to health. It is estimated that in the 1900s, in New York, around 20,000 people died per year because of diseases related to horse waste that were transmitted through the air. Therefore, the collection and disposal of waste was fundamental.

Given the growth projections, most historians agree that the use of the horse was not sustainable in the long term for three reasons: the management of waste, the increase in the cost of horse food that was already becoming more expensive than coal and because of the methane emissions that would have been released into the atmosphere due to a world mobilized by horses.

On the other hand, coal was the primary energy source for thermoelectric generation, steam engines and mobilization by railroad and ships. Therefore, in addition to the environmental impacts in its extraction, greenhouse gas emissions were also generated. In such a way that the great industrial cities of the time were characterized by soot, black clouds and poor air quality.

Although today hydrocarbons have become the villains to defeat in order to mitigate climate change, their adoption in the first quarter of the twentieth century allowed a first energy transition that helped improve the management of manure and coal and more. We will analyze this next week. Until then.

Digitalization: The Third D of the Energy Future




“Artificial intelligence is the new electricity”

–Andrew Ng

Digitalization is a topic very intimately linked to energy, but it is necessary to differentiate the exogenous and endogenous effects of this relationship. The exogenous effects of digitalization have more to do with the process of transformation of goods, products or processes. We have already addressed this: how currencies, records and books become chains of digital data that ultimately require electric energy. For example, we no longer use the Guía Roji to locate ourselves but Google Maps, and today’s students no longer need to have an illustrated encyclopedia but only access to Wikipedia.

To the above is added the digitalization of classic household appliances and other electronics that are not only automated, but also interconnected to internet networks, giving rise to the so-called internet of things. Beyond devices to which we have already become accustomed — computers, video game consoles and televisions —, this is also a trend in washing machines, refrigerators, air conditioners and even lighting in general; everything can be controlled through networks with a cellphone or another device connected to the same network of our house or even remotely through the internet.

But, on the other hand, there are endogenous effects of digitalization in the electric sector. Digitalization in turn implies a process of adaptation and rapid response to a changing environment such as greater integration of renewable energies and storage. Power plants and large consumption centers are interconnected through remote communication means, whether through conventional internet or satellite communications, in such a way that they can process information in real time and integrate it into a more robust network with intelligent dispatch.

Operators and intelligent networks connected in real time, together with generators and representatives of consumers and other marketers, would have the possibility of sending more precise data on generation and consumption, which would avoid the programming of excess generation and would reduce technical losses. Likewise, it could help a better integration of renewable energies in real time and also make precise information available to citizens instantly.

Accompanying this interconnectivity goes hand in hand artificial intelligence and data science for the development of algorithms and self-learning machines that allow integrating a large amount of data in real time, such as weather, prices, operations, demand and storage, which would grant greater reliability in the operation of the electric system.

Additionally, consumption centers integrate smart meters and distributed generation and storage systems that can interact continuously with the network and enable the sale of solar or stored energy; controllable demand and other products for the benefit of the network. In case of non-payment, it also allows remote disconnection and connection without crews of technical bodies or long waiting times.

A smart home could decide whether at a given moment of the day it uses energy from the grid to store it or to charge an electric car; or else sell energy from a distributed generation system or share it with its neighbors or, why not, donate its surplus to a nursing home, church or school.

Digitalization and interconnectivity are, undoubtedly, two of the topics that reflect the bright future of the electric sector, decentralized and decarbonized, and this enables something else: democratized. We will talk about that next week.

Decentralization: The Second D of the Energy Future








I buy everything from ACME, they are the company I trust the most.

– Wile E. Coyote

A fundamental aspect of the centralization that characterizes the electric sector lies in the maxim that says: “the bigger, the better.” For example, the bigger a generation plant is, the cheaper the energy is and therefore investment is made to take it from the distant production centers to the consumption centers. Right?

According to the logic of electric centralization, few large companies are required to make all the investments in generation and also in transmission and distribution lines to take energy to consumption centers. In such a way that production is centralized in vertically or horizontally integrated companies.

To illustrate the above, do you remember the Coyote from the “Looney Tunes” animated series? Created in 1949 with his co-star the Road Runner, in more than 70 years of life he has dedicated himself to the fruitless task of hunting the fast bird. For this he has used products from the ACME company, on which I will stop a little.

The ACME company is an acronym that means, translated into Spanish, “A Company that Makes Everything” and was the clear reflection of the companies of the 1950s. General Electric, for example, made the same irons, stoves, toasters, televisions, refrigerators; garbage burners, coal stoves, jet turbines and, in a futuristic vision, electric cars and their home chargers, to which we will dedicate an article later.

ACME, like GE, like the electric companies of old — known as utilities —, are part of that type of organization. However, since the 1970s this model entered into crisis and was replaced by smaller and more dynamic companies, reducing competitiveness to the large ACMEs. Eventually companies such as GE or the electric utilities began divesting assets and less competitive business branches.

If technological advance has taught us anything, it is the importance of miniaturization, individualization and personalization of products and services. Where before there was a landline telephone, now there is a smartphone for each member of the family. Why should it be different in the electric sector?

Smaller and more flexible plants are cheaper and easier to operate, they can be located near large consumption centers and, therefore, be more competitive than the large plants of old, and among these are solar plants. The development of small solar plants between 0.5 MW and up to 10 MW has grown everywhere in the world under that logic and has lowered the costs of electric energy in the most sophisticated markets.

But it does not end there. What is closer to the consumer than generating on their own roofs? The growth of solar panels on the roofs of residential, commercial, industrial users and even government offices has grown in those markets where regulation is more favorable, for example, California.

The energy future outlines a true trend of decentralization, users who take control of their consumption and require, increasingly less, energy from large production centers, cooperatives that create microgrids for self-consumption or entrepreneurs who use their land to sell energy near the cities.

And this is only the beginning, when electricity storage is economically viable, an important part of consumers will use increasingly less energy coming from large power plants.

Electric decentralization is synonymous with freedom and energy independence of consumers and goes hand in hand with the decarbonization of the sector. Undoubtedly, it will be a reality sooner rather than later.
