NEW ANALYSIS: UK emissions fell 2.4% in 2025 as coal fell to a 400-year low. Incredibly, we used less coal last year than than in 1600, when Queen Elizabeth I was on the throne and Shakespeare was writing Hamlet.

El gráfico que muestra la relación entre migración y economía en España La economía española sigue atrayendo inmigrantes porque tiene oportunidades que ofrecerles. Pero esos inmigrantes son ahora estructuralmente necesarios para que esas oportunidades sigan existiendo.

What a privilege to present our research on Navarra’s renewables industrial take off at Glasgow University! Great Q&A session, lots of meat for thought and the conviction that this needs to become a book.

Screenshot with text: "Throughout most of its history, the United States has been
confident of an endless supply of energy. The first government
involvement in energy management developed after World War II.
Forecasts of a future energy crisis led President Harry Truman to
establish the Materials Policy Commission. The Commission was
mandated to investigate potential shortages of vital resources. In
1952 the commission recommended that the United States set up a
federal energy agency and begin solar energy development. Discovery
of large oil deposits and faith in the future of cheap nuclear energy
led the federal government to disregard the commission's
recommendations."

Interesting opening paragraph from a 1982 report.

Some meat for thought about the Spanish blackout. I keep saying it is more about social sciences (markets,incentives, regulation) than about technology! -as most of our current pressing problems!

WEHC Keynote 3. 30th of July 2025. 6pm. AF Borgen Lund. YouTube video by Lund University

Here you have my keynote at the #WEHC2025 where I did explain lots of things about energy history (and present, and future).

The bit about the adoption of electric lighting got missing from the video! (read Roger Fouquet instead!)

China starts building world’s biggest hydropower dam 1.2tn yuan project has broken ground in Tibet, premier says, despite fears of downstream nations India and Bangladesh

The scale of this is hard to comprehend.

If this dam is built and generates at the advertised output (300 TWh), it would generate more electricity annually than every natural gas plant, nuclear plant, coal plant, wind farm and solar farm in Canada, combined (261 TWh in 2023). 😳

How electricity meters distort the role of rooftop solar generation On-site consumption of PV output is invisible to the meter, and shows up as a reduction in electricity consumption. Does this matter? Yes, it does.

Without the ability to know what the total energy use of their customers with PV installed, utilities won't be able to efficiently, in terms of cost, pollution, and meeting demand, make plans related to securing adequate generation capacity. #EnergySky #HeatPump
