The Ember Subnational Data Methodology guide describes the data collection and calculation processes for electricity generation, capacity, and emissions across subnational regions in India and the United States.

This guide details the data methodology used by Ember to produce datasets on global electricity generation, net imports, demand, installed power capacity, and emissions from 2000 to 2021.

This report by Ember examines how the closure of the Strait of Hormuz exposes the fragility of global fossil fuel dependencies, particularly in Asia, and argues that scaling 'electrotech' (EVs, solar, wind, batteries, and heat pumps) provides a viable path to energy security and economic independence.

This executive summary from Ember reports that while wind and solar energy reached a record 10.3% of global electricity generation in 2021, global electricity demand grew faster than clean energy could keep up with. This resulted in record-high coal generation and CO2 emissions from the power sector in 2021, driven largely by demand increases in Asia.

This executive summary from Ember reports that while wind and solar power reached a record 10.3% of global electricity generation in 2021, global electricity demand grew faster than clean energy could keep up, leading to record-high coal generation and CO2 emissions.

This fact sheet by Energy Innovation examines the increasing frequency and severity of extreme weather events, such as droughts and floods, attributing these shifts to human-induced climate change and rising carbon dioxide levels.

This guide by Energy Innovation provides a blueprint for U.S. state policymakers to mitigate the economic impacts of the One Big Beautiful Bill Act (OBBBA). It specifically focuses on accelerating the procurement of wind and solar energy to ensure projects qualify for federal tax credits before they expire.

This fact sheet by Energy Innovation analyzes the potential impacts of the Advanced Clean Cars II (ACC II) rule, which mandates increasing sales of new zero-emission vehicles (ZEVs) starting in 2026 to reach 100 percent by 2035. Using the Energy Policy Simulator model, the document evaluates the benefits for the 16 '177 States' that can adopt this California-led standard under the U.S. Clean Air Act.

This report examines the need for U.S. electric utility business models and regulatory frameworks to evolve to support a high-penetration renewable energy future. It proposes a spectrum of utility roles—ranging from minimal involvement to becoming comprehensive energy services providers—and suggests shifting from traditional cost-of-service regulation toward performance-based models like the UK's RIIO to align utility incentives with societal climate and efficiency goals.

This fact sheet by Energy Innovation analyzes the gap between the emissions reductions projected from the Inflation Reduction Act (IRA) and the United States' 2030 Nationally Determined Contribution (NDC) target. Using the U.S. Energy Policy Simulator (EPS), the document identifies additional policy measures across electricity, industry, transportation, and buildings necessary to reach the NDC goal.

The 'Coal Cost Crossover 3.0' fact sheet by Energy Innovation reports that 99% of 210 analyzed U.S. coal plants are more expensive to operate than replacing their capacity with new wind or solar energy. The document highlights how the Inflation Reduction Act (IRA) accelerates this transition and estimates that replacing 204 coal plants with local clean energy could generate up to $589 billion in investment for energy communities.

This report by Energy Innovation analyzes the rising costs of coal-fired power generation in the United States between 2021 and 2024, concluding that coal is becoming increasingly uneconomic compared to alternatives like wind, solar, and natural gas.

This policy brief by Energy Innovation evaluates the greenhouse gas (GHG) intensity of natural gas versus coal power plants, concluding that while natural gas can reduce emissions compared to coal over a 100-year period, it is not a sufficient solution for climate change and can be counterproductive if methane leaks are high or if it displaces renewable energy.

This fact sheet from Energy Innovation outlines how data center electricity demand can be made flexible through workload shifting, operational reductions, and the use of backup power or storage to minimize the need for new fossil fuel generation and grid infrastructure.

This case study examines the role of the U.S. government in advancing diesel internal combustion engine technology. It details how federal investments in basic combustion research, the development of simulation tools, and the establishment of public-private partnerships led to significant improvements in fuel efficiency and a dramatic reduction in harmful emissions for heavy-duty trucks between the 1970s and 2010.

This briefing from Energy Innovation provides a blueprint for U.S. state policymakers to maintain energy efficiency and electrification progress in buildings and industry following the passage of the One Big Beautiful Bill Act (OBBBA), which the author projects will negatively impact the U.S. economy.

A guide by Energy Innovation outlining the eligibility criteria for federal tax credits for new and used passenger electric vehicles, including MSRP limits, income caps, and battery sourcing requirements.

This fact sheet from Energy Innovation outlines how the Inflation Reduction Act (IRA) transforms clean energy economics in the United States and provides a roadmap for state-level policymakers to maximize these benefits. It argues that while the IRA provides significant incentives to reduce greenhouse gas emissions and lower costs, state action is required to realize this potential.

This fact sheet from Energy Innovation outlines how the Inflation Reduction Act (IRA) provides foundational support for decarbonizing the United States building sector through rebates, tax credits, and funding for building codes, while emphasizing the need for complementary state, local, and Tribal government actions to ensure successful implementation.

This briefing by Energy Innovation analyzes the economic impacts of the U.S. Senate's version of the "One Big Beautiful Bill Act," passed on July 1st. The analysis forecasts that the bill's energy provisions—specifically the phase-out of clean energy tax credits and new material sourcing requirements—will reduce electricity capacity, increase power prices for consumers, and decrease U.S. GDP and employment.
