What is the Rosenfeld effect?

In Lumisa we are lovers of the stories of entrepreneurship and innovation, so before telling you what the Rosenfeld effect is, we want to explain to you who this gentleman was.

Arthur G. Rosenfeld, was born in Alabama in 1926. When he was very small he lived in Egypt as they had to move because of his father's work. There he had the opportunity to meet many Europeans and acquired the savings culture that the Americans lacked.

He studied particle physics with Enrico Fermi, a very important physicist, with whom he wrote a book. He taught during the Second World War, in which he taught radar operations. He developed a privileged mind that helped him to see further and realize the great waste his country was making when it came to using energy when very few cared about it.

Later in 1954 he devoted himself to teaching at the University of California at the same time he joined the department of physics, to investigate particle physics.

At one point in his brilliant career, in 1973 when the crisis caused by the second Arab oil embargo occurred, he became saturated seeing the great waste that the Americans were making. His colleagues focused on finding ways to produce more energy and he, on the contrary, wanted to learn new ways to reduce energy consumption, thereby committing to the environment and sustainability.

True to his convictions, he turned his attention to particle physics and directed it toward energy efficiency by creating a scientific research center at the Lawrence Berkeley National Laboratory.

He and his team developed new technologies such as the coating of windows that trapped heat, fluorescent lights that reduced energy consumption substantially, the design of buildings and appliances, among others, all of them dedicated to a much more sustainable consumption.

His commitment was the basis for a large number of researchers motivated to change, to follow him and to unite in his mission. Based on work, it led to gradually all of California adapting to its saving spirit.

In 2011, then President Barack Obama, awarded Rosenfeld the Medal of Technology and Innovation.

So what exactly is the Rosenfeld Effect?

This story that we have told you so passionately, is extraordinary for the results it produced.

Today, per capita electricity spending in California has remained stable since 1973, while in the rest of the United States electricity consumption has increased by no less than 50%.

This fact is known as the Rosenfeld effect, and is attributed to the savings and energy efficiency that Arthur has left as a legacy. He passed away last year and in his honor the Rosenfeld unit of measurement has been created, which is used to calibrate energy savings.

Rosenfeld would be equal to the electricity consumption of a city of 250,000 inhabitants, serving as a comparison measure between different cities to calculate savings.

Hopefully this article has inspired you as much as we did.
