OEO Blog: You can’t just do one thing (when it comes to decarbonization)

To fully understand the emissions reductions and cost impacts, you must consider the entire system’s response rather than evaluating each action in isolation.

OEO Blog: Energy modeling and the demise of Chevron

What do a pair of Gorsuchs have to do with the fundamental relationship between the U.S. Executive, Legislative, and Judicial branches? And what does any of this have to do with power sector modeling? The short version is, quite a bit.

OEO Blog: Energy use for artificial intelligence: Expanding the scope of analysis

Stakeholders have expressed concerns over the energy used to support the development of artificial intelligence and machine learning (AI/ML) tools and their applications.

OEO Blog: TEMOA modernization

In an effort to keep TEMOA central to the Open Energy Outlook (OEO) Initiative’s success, the OEO team initiated a significant code modernization project to produce TEMOA version 3.0.

OEO Blog: Diverse solutions in energy system optimization

Energy systems models are invaluable planning tools. However, these tools typically produce singular “cost-optimal” solutions that can overlook other solutions that may be more viable when considering non-cost factors.

Fueling Change: Understanding the Impacts of the Proposed Rule for Hydrogen Tax Credits on Greenhouse Gas Emissions from the US Energy Sector

Since burning hydrogen does not emit greenhouse gases, it could replace fossil-based products and their combustion emissions. However, different hydrogen production technologies can lead to different upstream emissions. Thus, the net impact on emissions from hydrogen must account for how hydrogen is produced.

Navigating the LNG Dilemma: Debates, Delays, and Decisions in a Shifting Energy Landscape

The natural gas industry is seeking to expand the market for US-produced natural gas and argues that LNG exports would replace coal in other countries and thus reduce global CO2 emissions. On the other hand, some environmental advocates argue that natural gas has a higher climate impact than coal and the approval of the LNG terminals would be a betrayal to President Biden’s climate ambitions.

OEO Blog: It’s not a cold shoulder, but a winter’s peak

When should we expect the highest levels of electricity consumption? Could it be when lots of folks in the UK turn on their electric tea kettles at the start of the World Cup halftime? Or maybe when Swifties boot up every electronic device they can find to get tickets for the Eras Tour? It might have seemed like it in my household, but the answer is often much simpler.

OEO Blog: Navigating electrification in decarbonization: Understanding behaviors and challenges

"Electrification” is expected to play a key role in decarbonizing our energy system. This blog summarizes electrification, discusses its potential impact on emissions, and anticipates often-overlooked behavioral changes influencing energy transitions.

OEO Blog: Beyond the Inflation Reduction Act: Achieving net-zero greenhouse gas emissions in the U.S.

Recent analyses estimate that the Inflation Reduction Act (IRA) will reduce U.S. greenhouse gas emissions by 40% (in 2030 relative to 2005 baseline levels).

OEO Blog: More than energy system modeling: Developing a socio-technical feasibility space for energy system transitions

Energy systems models are used extensively to plan net-zero CO2 emissions globally by 2050, a critical step in mitigating climate change. These models serve as indispensable tools, offering insights into myriad energy transition pathways characterized by diverse fuel and technology options that achieve net-zero emissions. In the United States, significant modeling efforts have identified a crucial need for technological flexibility. As indispensable as these models are, recognizing and addressing their limitations can produce more comprehensive and equitable decarbonization strategies.

OEO Blog: An Introduction to the Open Energy Outlook model and recent applications

Energy systems are complex, involving millions of interconnected technologies that extract, convert, store, and move energy from diverse sources to everyday uses. As a result, changes to one part of the energy system can have ripple effects elsewhere. Changes to domestic and international markets and policy further complicate energy systems by influencing energy supply, demand, prices, and equity.

OEO Blog: What sets the open energy outlook apart

The Open Energy Outlook (OEO) for the United States is a modeling effort funded by the Alfred P. Sloan Foundation, which aims to rigorously examine different technology and policy pathways across the whole energy system that achieve deep decarbonization. Our Roadmap lays out our detailed plans for this effort. In this blog post, we describe several features that set our effort apart from others.
