The electric chair was once the primary method of execution in the United States, but its use has gradually declined since the 1990s due to the widespread adoption of lethal injection. As of 2024, only seven US states still reserve the electric chair as an option for execution, and even in these states, inmates typically have a choice between electrocution and lethal injection. The electric chair is designed to deliver a high-voltage shock that overwhelms the heart and brain, but it is not always instant or painless, and some inmates choose it over lethal injection due to fears of feeling intense discomfort from the drugs used in lethal injections.

Electric chair vs lethal injection
The electric chair was first built in 1888, and New York executed William Kemmler in 1890. Soon, other states adopted this execution method. However, its use has gradually declined since the 1990s due to the widespread adoption of lethal injection. Lethal injection is the most widely-used method of execution. However, many states still authorize other methods, including electrocution, lethal gas, and firing squads.
As of 2024, the only places that still reserve the electric chair as an option for execution are the U.S. states of Alabama, Arkansas, Florida, Kentucky, Louisiana, South Carolina, and Tennessee. In Tennessee, death row inmates can choose the method by which the state will end their lives. Increasingly, they are choosing the electric chair. Nationally, the electric chair is a method of the past; no other state has used it since 2013. However, inmate advocates and lawyers say that condemned men in Tennessee are choosing electrocution because they fear being frozen in place and feeling intense discomfort while the drugs take effect.
The execution process for lethal injection involves a series of injections. The first injection sedates the prisoner, followed by others that paralyze them and stop their heart. On the other hand, the electric chair involves two cycles of 1,750 volts of electricity. The entire execution process takes about eight minutes.
Some legislators have advocated for a return to the electric chair as a mandatory method of execution because of the difficulty in finding lethal injection drugs. Lethal injection drugs are often in short supply due to resistance from drug manufacturers.

History of the electric chair
The electric chair is a device used for capital punishment through electrocution. The method involves strapping the condemned person to a custom wooden chair and attaching electrodes to their head and leg. A jolt of between 500 and 2000 volts is then delivered, lasting for about 30 seconds. If the prisoner's heart is still beating, another jolt is applied.
In the late 19th century, death by electric chair was adopted as a more humane alternative to hanging. The idea for the electric chair was conceived by Alfred P. Southwick, a dentist from Buffalo, New York, in 1881. The inspiration came from a series of accidents involving high-voltage arc lighting, which was used for outdoor street lighting. One such accident occurred in Buffalo, New York, on August 7, 1881, when a drunken dock worker named George Lemuel Smith sneaked into a power plant and grabbed hold of a large electric dynamo, resulting in his death.
In 1886, the newly elected New York State governor, David B. Hill, formed a commission to investigate more humane means of execution. The commission included human rights advocate Elbridge Thomas Gerry, New York lawyer and politician Matthew Hale, and Alfred P. Southwick. They consulted electrical experts, including Elihu Thomson and Thomas Edison, and attended electrocution experiments on dogs. In 1888, the commission recommended electrocution using Southwick's electric chair idea, with metal conductors attached to the condemned person's head and feet.
The first execution by electric chair was carried out by the state of New York on August 6, 1890. William Kemmler was the first person to be executed by this method. The electric chair was promoted as a humane, civilized, and technologically advanced form of execution. However, the first use of the electric chair was botched, with witnesses reporting the smell of burning flesh and some even fainting or becoming nauseous. Despite this, more and more states adopted the electric chair as a method of execution in the following years.
While the electric chair was once the primary method of capital punishment in the United States, it has largely been supplanted by lethal injection in recent decades. As of 2025, electrocution remains an option in some states, including Alabama, South Carolina, and Florida, where inmates may choose between electrocution and lethal injection. However, the use of the electric chair has been declining, with Nebraska ruling it unconstitutional in 2008, and other states following suit.

States that still use the electric chair
The use of the electric chair for executions in the United States has been in decline since the 1990s due to the adoption of lethal injection, which is considered more humane. Lethal injection is the primary means of execution in all states where it is legal, except South Carolina.
As of 2024, the electric chair is still an option for execution in eight US states: Alabama, Arkansas, Florida, Kentucky, Louisiana, South Carolina, Tennessee, and Mississippi. In some of these states, the use of the electric chair is dependent on certain criteria being met.
In Arkansas, Kentucky, and Tennessee, inmates sentenced before a certain date can choose to be executed by electric chair. In Tennessee, death row inmates can choose the method of their execution, and in the case that lethal injection drugs are unavailable, the electric chair can be used without prisoner input. In South Carolina, electrocution is the primary method of execution, but inmates may choose lethal injection instead.
In Mississippi, Oklahoma, and Louisiana, electrocution is authorized if lethal injection is deemed unconstitutional or unavailable. In Florida, electrocution is authorized if lethal injection is found unconstitutional.
The most recent electrocution in the US took place in February 2020 in Tennessee.

Is electrocution humane?
The electric chair was conceived in 1881 as a more humane alternative to hanging. The first electric chair was built in 1888, and it was first used for execution in 1890. The electric chair was widely adopted in the United States, becoming the prevalent method of execution and replacing hanging. However, the use of the electric chair has gradually declined since the 1990s due to the adoption of lethal injection, which is perceived as more humane.
The process of electrocution involves the condemned person being strapped to a custom wooden chair and electrocuted via electrodes attached to the head and leg. The electric current passed through the body causes ventricular fibrillation, where the heart muscle fibres contract in a rapid, uncoordinated manner, leading to cardiac arrest. Electrocution is intended to cause death by stopping the heart from pumping blood to the brain, resulting in cerebral damage and death.
While electrocution was initially considered a more humane alternative to hanging, there is considerable evidence to suggest that it can inflict unnecessary pain, indignity, and physical mutilation on the inmate. For example, during the execution of Jesse Tafero in Florida in 1990, his face and head caught fire, and the execution ultimately required three shocks over seven minutes. Similarly, in 1997, flames burst from Pedro Medina's head during his execution in Florida. An autopsy found that Medina died instantly when the first surge of electricity destroyed his brain and brain stem.
In 2008, the Nebraska Supreme Court ruled that execution by electrocution was "cruel and unusual punishment" prohibited by the Nebraska Constitution. As of 2024, only seven US states still reserve the electric chair as an option for execution, and inmates in most other states must choose between electrocution and lethal injection. While some inmates in Tennessee have chosen the electric chair as their preferred method of execution, it is important to note that electrocution is not considered a humane method of execution by many, given the potential for unnecessary pain and suffering.

Alternatives to the electric chair
As of 2024, electrocution remains an option for execution in some U.S. states, including Alabama, Arkansas, Florida, Kentucky, Louisiana, South Carolina, and Tennessee. However, in recent years, there has been a shift towards alternative methods of execution, such as lethal injection, which is considered more humane. Here are some alternatives to the electric chair:
Lethal Injection
Lethal injection is the most widely used method of execution in the United States today. It involves a series of injections, the first being to sedate the prisoner, followed by others that paralyze them and stop their heart. While it is considered a calmer and less violent option than electrocution, there have been concerns about the level of pain and suffering caused by this method, particularly if the injections are not administered correctly.
Lethal Gas
Lethal gas was introduced in Nevada in 1924 as a more humane alternative to hanging. The prisoner is strapped to a chair in an airtight chamber, with a pail of sulfuric acid below. While lethal gas is authorized in some states, all of them offer lethal injection as an alternative method.
Firing Squad
The firing squad has been used historically in some states, including Ohio, and was recently reinstated as the primary method of execution in Idaho in 2025. The prisoner is typically bound to a chair, and a group of shooters, usually five, fire at the prisoner simultaneously. South Carolina's protocol, for example, calls for three shooters, each armed with .30-caliber rifles.
Nitrogen Gas
Nitrogen gas is a newer method of execution, recently used in Louisiana in 2025. It is considered a more humane alternative to other methods, although there are limited details available on the specifics of its use.
Other Alternatives
In some states, there is a provision for alternative methods of execution if lethal injection is deemed unavailable or unconstitutional. For example, in Tennessee, the electric chair can be used if lethal injection drugs are unavailable. Additionally, in Mississippi and Oklahoma, the electric chair can be used if other methods are ruled unconstitutional.

Frequently asked questions
Yes, as of 2024, the electric chair is still an option for execution in Alabama, Arkansas, Florida, Kentucky, Louisiana, South Carolina, and Tennessee.
Lethal injection is the most widely-used method of execution. However, some inmates choose the electric chair over lethal injection because they fear being frozen in place and feeling intense discomfort while the drugs work to kill them.
A jolt of between 500 and 2000 volts, which lasts for about 30 seconds, is given. The current is then turned off, and doctors wait for the body to cool down before checking if the prisoner's heart is still beating. If it is, another jolt is applied.
The electric chair was supposed to be more humane than other methods of execution, like hanging. However, the process of dying by electric chair is extremely painful as the heart and brain are active until the very end.
Lethal injection was developed to be more humane than electrocution. However, it is not without its flaws. For example, botched procedures have left inmates writhing in agony.
