Our report on direct federal financial interventions and subsidies in energy markets continues a series of EIA reports1 that respond to congressional requests and the Energy Policy Act of 1992. In this update, we introduce multiple, sequential fiscal year2(FY) data for the first time from FY 2016 (the last fiscal year we. . This overview and key findings section is followed by three appendices: 1. Appendix A presents detailed tables 2. Appendix B presents our analytic approach 3. Appendix C provides a listing of select other subsidy reports. . Several key findings stand out. Beginning in FY 2016, tax expenditures rose rapidly and leveled off, but direct federal support remained steady until Congress recently enacted temporary. Table A1 summarizes total within-scope energy subsidies (in 2022 dollars) and selected U.S. energy system indicators (in physical units). Table A3 summarizes the allocation of federal direct financial interventions in U.S. energy markets by year and energy type, and it serves as the basis for Figures 1-7. [pdf]
The most obvious subsidies are the direct expenditures and R&D support from the federal budget. Tax expenditure subsidies are targeted tax incentives that producers or consumers of specific forms of energy receive. In this case, the government does not spend money, but it loses revenue that it would have otherwise received.
However, fossil fuel subsidies for consumers remain elevated compared with their historical averages. While subsidies generally aim to make energy more affordable for consumers, many are poorly targeted and disproportionately benefit higher-income groups.
DOE=U.S. Department of Energy. Total renewable subsidies increased from $7.4 billion in FY 2016 to $15.6 billion in FY 2022. Tax and direct expenditures combined accounted for about 97% of total renewable subsidies over that period.
The technologies recognized in today’s NPRM include wind, solar, hydropower, marine and hydrokinetic, nuclear fission and fusion, geothermal, and certain types of waste energy recovery property (WERP). The proposed guidance also clarifies how energy storage technologies would qualify for the Clean Electricity Investment Credit.
The IEA estimates subsidies to fossil fuels that are consumed directly by end-users or consumed as inputs to electricity generation (see explanation of the price-gap methodology). A time series of these estimates from 2010, by country and fuel, is available as a free download.
In FY 2016, the Internal Revenue Code (IRC)—with its 31 wide-ranging, energy-specific tax provisions—provided greater financial support to energy than direct expenditures, including R&D expenditures (Table A2 and Table A3). Total tax expenditures were 70% of the total federal financial support (Table 1).

Learn about critical size-up and tactical considerations like fire growth rate, thermal runaway, explosion hazard, confirmation of battery involvement and PPE. . The impact of lithium-ion battery involvement on fire growth rate suggests that when firefighters respond to these incidents, they should. . Lithium-ion batteries may go into thermal runaway in the absence of active fire. Thermal runaway can be recognized as distinct white or gray. . There are no reliable visual, thermal imaging or portable gas meter indicators to confirm battery involvement in a room and contents fire. . This begins the instant batteries undergo thermal runaway and release gas without burning. The timing and severity of a battery gas explosion is unpredictable. Firefighters are at greatest. [pdf]

Our planet is entrenched in a global energy crisis, and we need solutions. A template for developing the world's first renewable green battery is proposed and lies in storing electricity across the grid. Iceland generates 100%. . With aging infrastructure and renewable energy (RE) generation on the rise, there has never been a more urgent need for a modern electricity grid. Many envision this modernized smart grid. . Originally when we set out on this idea, the leading-edge technology for digitally modelling our fancy electric grid was the Grid. [pdf]
The story of Iceland’s transition from fossil fuels may serve as an inspiration to other countries seeking to increase their share of renewable energy. Was Iceland’s transition a special case that is difficult to replicate, or can it be applied as a model for the rest of the world? Iceland’s energy reality
Renewable energy here is the sum of hydropower, wind, solar, geothermal, modern biomass and wave and tidal energy. Traditional biomass – the burning of charcoal, crop waste, and other organic matter – is not included. This can be an important energy source in lower-income settings. Iceland: How much of the country’s energy comes from nuclear power?
This way the water is continuously recycled and carbon emissions are dealt with at the same time, an example of how efficient Iceland is with its geothermal resources (a topic which will be covered in greater depth in the Winter issue of Energy Global). ON Power's Hellisheidi geothermal powerplant.
Just as geothermal and hydro power generation made sense for energy transition in Iceland, local conditions elsewhere will determine which renewable resources are the most efficient and how they will be best exploited. Because every country is unique, each transition will be different.
Today, Iceland’s economy, ranging from the provision of heat and electricity for single-family homes to meeting the needs of energy intensive industries, is largely powered by green energy from hydro and geothermal sources. The only exception is a reliance on fossil fuels for transport.
It is widely used to melt snow off sidewalks, heat swimming pools, power fish farming, greenhouse cultivation and food processing, as well as for the production of cosmetics, such as merchandise from Iceland’s famous geothermal spa, the Blue Lagoon.
