Public Power Decarbonization Series
This article is Part 1 of a three-part series on the role of Public Power in decarbonizing and electrifying our society and economy. In this first article we establish the clear imperative to decarbonize and what that means for Public Power. In Part 2, we review the Crisis of Slow Public Power Decarbonization. In Part 3, we connect the dots between decarbonization and distributed energy resources (DER), showing a second imperative for public power: integrating DER into utility grid modernization. As we continue this series, we’ll explore a wide variety of impacts, constraints, risks, costs and benefits, including supply chain issues, the broad impact of decarbonization on our society and economy, and the upsides of an Electrify Everything Economy.
Part 1: The Decarbonization Imperative
“Human activity is changing the climate in unprecedented and sometimes irreversible ways.” The United Nations Intergovernmental Panel on Climate Change (IPCC) released its latest report in August 2021 calling the current state of the global climate a “Code Red for humanity.” UN Secretary General Antonio Guterres stated, "If we combine forces now, we can avert climate catastrophe. But, as today's report makes clear, there is no time for delay and no room for excuses.”
Now is the time to be aggressive, ambitious, and unambiguous about electrification and decarbonization.
Some of the climate changes that have occurred or are occurring have now become too late to avoid. Even with immediate action, the Greenland ice sheet will continue to melt, leading to rising sea levels, increasing acidity levels, and a possible shift in the Gulf Stream in the years ahead, with massive weather impacts. Heat waves, droughts, and the number and severity of tropical storms will increase. This means intense heat and wildfires in the West (and now other parts of the US), with severe storms and temperature swings throughout the country.
At this point, climate change has become pretty obvious to everyone. Yale’s 2018 climate change survey showed that 70% of Americans believe climate change is happening, and 58% believe it is caused mostly by humans. Those numbers have almost certainly grown since then.
The facts have become strikingly obvious, and these data do not lie. The last six years are the hottest in recorded human history. Extreme weather events happen more often and when they do, they’re more severe. The polar ice sheets are now melting at rates not seen since the Ice Age thousands of years ago. Fires, droughts, and species extinctions are now happening at rates never seen by humans. And these extreme weather impacts are occurring at our current level of between 1.2 and 1.3 degrees of warming. (Source: Climate Action Tracker: Climate Summit Momentum – Paris Commitments Improve Warming Estimate to 2.4 Degrees). Alarmingly, even with herculean efforts to decarbonize and electrify, things will get worse before they start to get better.
The following table provides data from NASA on some of the key climate change metrics:
Sea Level Rise
↑3.3 mm per year
8 inches in last century and accelerating
Carbon Dioxide (CO2)
Highest amount in 800k years
Annual loss has tripled in last decade
Since Industrial Revolution

Scientists and most of the world’s population recognize that climate change is real, that it’s caused by human activity, and that it’s due to Greenhouse Gas (GHG) emissions – primarily carbon dioxide (CO2) and methane (CH4), which are both byproducts of burning fossil fuels. The inescapable conclusion is that we must stop burning fossil fuels - we must decarbonize – and that means we must Electrify Everything.

The rate at which the climate is changing even caught the IPCC by surprise. This is all happening much faster than was predicted. Climate change is non-linear. As a metaphor, consider a spinning top. It spins in equilibrium with minor perturbances until it slows down. At that point, the spinning becomes enormously unstable and unpredictable, and it wobbles out of control. In fact, many scientists believe we are exiting the very stable geologic Holocene Epoch and have entered a new, man-made Anthropocene Epoch. In the blink of an eye, our planet has moved from Global Warming to an outright Climate Emergency. With our global house on fire, we must respond accordingly to what has become an existential crisis. Reducing the impact of the Climate Emergency on our one-and-only home planet and preserving a livable place for all inhabitants requires immediate, radical action.
Some key takeaways from the IPCC report are:
- Code Red for Humanity. We are in a climate crisis and we must act immediately. Time is running out. Every bit of GHG emissions we can avoid today will help since atmospheric carbon is cumulative and takes many years to dissipate.
- Anthropogenic Change. It is undeniable that humans are responsible for atmospheric carbon increases that are the most in 2 million years. The growth and speed of this change is unprecedented in human AND earth history.
- The Power of Inertia. We have already gone too far to avoid some climate change. Some changes are irreversible. We will continue to see the glaciers and ice sheets melt even if we stopped all carbon emissions today. Oceans will become more acidic, warmer, and continue to rise. Precipitation, heat waves, and more severe weather extremes are unavoidable.
- Increasingly Obvious Signs of Change. The most obvious signs of rapid climate change are observed in polar regions where there are clear and measurable effects on sea ice and glaciers. Warming in tropical areas is also apparent because natural year-to-year changes are normally very small. Long-term changes in other variables such as rainfall and some weather and climate extremes have also now become apparent in many regions.
- Better Models Speak Truth. Five different climate future scenarios were modeled with much greater fidelity than previous models. The models ranged from steady GHG and CO2 emissions growth to varying levels of net negative CO2. In ALL scenarios, global surface temperature will continue to increase even if we can enact dramatic, deep reductions in CO2 and other GHG emissions in the next two decades.
All in all, the IPCC’s 2021 Climate Assessment Report was bad news for the Earth, humans, and most of Earth’s inhabitants. Although not all hope has been lost, it’s clear that we’re quickly running out of time – and the most impactful and best path to address the biggest challenge in human history: rapid decarbonization of energy generation and use.

Since the Yale survey, belief and concern about climate change in the US has risen to political centerpieces that match the “will of the people”. We the People want action now, and the Biden administration has made climate change one of the key pillars of its policy. Biden’s legacy as an American President is tightly coupled with the outcome of those policies, but he needs supporting action throughout American society and economy to take the politically risky steps that are necessary. A large sum of stimulus money in the Infrastructure Bill to reduce carbon emissions is targeted at the utility industry ($73B has been earmarked for transmission and “advanced technology” projects out of the recent $1T infrastructure bill). Another $198B is earmarked in the upcoming 'human infrastructure bill" for the Energy and Natural Resources Committee, including funding instructions largely related to clean energy development.

Where this money will be spent is equally as important as how much money is made available. In a previous stimulus bill (i.e., ARRA in 2008), the overwhelming majority of federal investment dollars was targeted towards Investor-Owned Utilities and Technology and Manufacturing. In the remaining two articles in this series, we’ll make the case for Public Power Municipal Utilities, showing why unregulated, local, customer-focused small utilities are the best target sector to use federal funding to achieve real decarbonization innovation and realize US climate goals.
