GEOS Insights: Season of Solstice
Photo: Bill Page, 2024

As we approach the winter solstice in the Northern Hemisphere, this special day has both cultural, spiritual and astronomical significance. The solstice symbolizes birth and renewal as the days grow longer after winter solstice. Astronomically, this event occurs twice a year globally in each Hemisphere, when the Earth’s axis is tilted at its farthest point from the Sun. It is also the season of light, as traditionally people bring the light into their dwellings for holiday celebrations.
As we approach year end, we are also reflecting on the past year professionally, as we manage our thematic clean tech strategy, Essex GEOS. After recent travels featuring conferences and meetings, as well as industry peer conversations, we want to make some points we have been expressing often lately, to questions, concerns and confusion about the state of clean technology progress.
Clean technology is successful and progressing.
Policy does not drive technological progression – physics does. Despite headlines that express our federal government arresting wind and solar power, the sources are taking share given economics:

This chart using Lazard data and published last week by Bloomberg illustrates on a levelized cost basis solar and onshore wind are the most competitive sources of electricity to drive economic growth. So far this year, solar and wind are expanding fast enough to meet all new electricity demand, supplying 18% of global electricity demand according to Ember. For the first time, low carbon energy sources surpassed coal, and solar growth was over three times greater than any other energy source this year.
Corporate clean energy buyers are taking note.
Through November, the top corporate clean energy buyers are Meta, Google, Amazon and Microsoft globally. Google has procured over 3 gigawatts (GW) of clean energy year to date, overtaking Amazon. Solar is the dominant energy source given economics and advantages such as dispatchability, representing over 50% of all clean energy power purchase agreements this year.
Clean tech successes are not noticed by most investors
The demand drivers for clean energy, from resource efficiency to onshoring pressures are driving profits for the sector, from industrial automation to utility scale solar players. There is a direct link between economic growth and power and resource demand, and clean technology applications optimize productivity and economic growth. The profitability profiles for commercially viable clean tech companies are improving and leading to better fundamentals such as orders and margins. It is early days in the recovery, but as the stock prices for these companies continue to improve, investors may begin to take note. Think of it as the winter solstice.
Best to you for the solstice, and the holidays into year-end, and for 2026.
