What Would Happen If The World Lost Electricity?

What would happen if the world lost electricity?

The concept of a total worldwide blackout of electricity is a frightening one. If all electric power generation suddenly stopped, it would cause catastrophic effects across every country. Within hours, critical infrastructure would begin shutting down, including transportation, healthcare, banking, food supply chains, and water delivery. Without electricity, all the systems we depend on for modern life would eventually fail. Emergency services would be severely hampered, telecommunications would go down, and economic trade would grind to a halt. Even if temporary, such a massive power outage would lead to trillions in damages, widespread unrest, and the potential for the loss of human life on a large scale. This hypothetical scenario illustrates how intricately interconnected and vulnerable our global society is when it comes to electricity. A prolonged global blackout could precipitate societal collapse, underscoring the need for better safeguards and infrastructure resilience.

Communication Systems Fail

In the event of a total loss of electricity, communication networks that rely on electrical power would be severely disrupted, including phone, internet, radio, and TV networks. Modern telecommunication systems require continuous power supply from the electrical grid in order to operate equipment like routers, switches, towers, data centers, and end-user devices (https://energy5.com/powering-communication-networks-the-role-of-electrical-systems-in-telecommunications). Without electricity, these systems would fail, interrupting services and cutting off connections.

Landline phones would stop working as the power failures cascade through telephone networks. Cellular networks would be impacted as towers run out of backup battery power within hours or days. Without electricity to power critical networking infrastructure, internet access would grind to a halt. Radio and television stations could potentially operate for a short time on backup generators, but would eventually go silent without grid power (https://www.energy.gov/sites/default/files/2023-11/Communications_in_the_Electric_Grid_An_Evolving_Interdependent_Ecosystem_between_the_Grid_and_Communications_Utilities-r1.pdf).

The loss of electricity would severely restrict communications capability, cutting off connections and information flow in today’s highly networked world. With communication networks paralyzed, it would be extremely difficult to coordinate any kind of large-scale response during the crisis.

Transportation Disrupted

Vehicles, trains, planes and ships rely on electricity to operate, so a total power outage would bring transportation systems to a halt. With no electricity, gas stations couldn’t pump fuel, traffic lights would go dark leading to gridlock, and public transit would cease operating. According to Chovančíková (2021), road and rail systems that transport people and goods would fail in a power outage. Air travel would also be severely disrupted, as evidenced by an outage at OR Tambo Airport in Johannesburg that grounded flights and stranded thousands of passengers, per Makope (2019). With no electricity, air traffic control systems would be inoperable, making takeoffs and landings impossible. Shipping and freight transport would be impacted as well, unable to load or unload cargo at affected ports.

Supply Chains Stop

The sudden loss of electricity would bring manufacturing and distribution to a halt, severely disrupting supply chains globally. Factories rely on electricity for production lines, machinery, lighting and inventory systems. Without power, assembly lines stop moving and warehouses grind to a dark standstill. Perishable items kept in cold storage start to spoil. Fuel supplies dwindle as pumps can’t operate to dispense gasoline, diesel or jet fuel. Some factories and warehouses may have backup generators, but fuel supplies for generators quickly run out.

According to a NREL report, the lack of domestically sourced renewable energy components makes the U.S. electric grid supply chain vulnerable to disruptions. New policies and investments to expand American manufacturing of solar panels, batteries, electric vehicles, and other clean energy technologies could strengthen this critical supply chain.

Farms and agriculture are also paralyzed without electricity. Milking machines, refrigeration, lighting, ventilation, and water pumping all depend on power. Crops stop growing as irrigation systems fail. Livestock suffer without climate control in sheds and barns. Food rotting in dark warehouses and stores ceases to reach markets and grocery store shelves run bare.

With transportation, manufacturing, and farming halting, the global supply chain seizes up. Businesses are unable to produce and distribute their products. Store shelves empty as inventories vanish. The entire worldwide web of interdependent trade is snarled in a monumental logjam.

Healthcare Crippled

If a widespread and prolonged blackout occurred, hospitals and other healthcare facilities would be severely impacted. Without electricity, life-saving equipment like ventilators, dialysis machines, and incubators would cease to operate, putting many vulnerable patients’ lives at risk.

According to the Energy5 article “The Effects of Power Outages on Society,” hospitals have backup generators, but fuel supplies for generators typically last only 1-2 days (https://energy5.com/the-effects-of-power-outages-on-society). Once fuel runs out, patient care quickly degrades. Surgeries would need to be postponed or canceled. Medical devices, lab equipment, and computer systems all rely on electricity. Refrigeration for medicine and blood supplies would fail. Running water, air conditioning, heating, and sanitation systems depend on power as well.

Healthcare facilities are designed to maintain patient safety, so a total loss of power creates an extremely hazardous situation. Doctors and nurses rely on lighting to administer care, so they cannot adequately treat or monitor patients without electricity. The most vulnerable like infants in the NICU and elderly on ventilators are put in mortal danger.

Water Services Fail

Without electricity to power pumps, the public water supply would stop flowing within hours or days in most areas. Water pumping stations and treatment plants require significant amounts of electricity to pump water from sources like reservoirs, purify it, and distribute it via pressurized pipes and pumps to homes and businesses.

According to Penn State University Extension, during a power outage “water may stop flowing out of your faucets.” Loss of pressure in the water lines can allow contamination to enter the system. Additionally, the American Water Works Association states that “even minor disruptions in electric service can result in complete loss of normal water service.”

Without the ability to purify and pump water, shortages would quickly occur in affected areas. consumption of contaminated water could also lead to the spread of diseases like cholera, typhoid, and dysentery, especially in dense urban areas.

Food Spoils

Without electricity to power refrigerators and freezers, perishable foods quickly spoil and become unsafe to eat. According to the CDC, refrigerated foods are only safe for up to 4 hours without power.1 Frozen foods will stay frozen for about 48 hours if the freezer is kept closed.2 Beyond that, bacteria growth causes food to spoil rapidly.

Without the ability to keep foods cold, people would be forced to consume non-perishable items. But grocery stores would also lose the ability to refrigerate fresh produce, milk, and other staples. According to one estimate, a power outage lasting just 4-6 hours could cause a grocery store to lose 35-45% of its perishable inventory.3 This would lead to major food shortages and supply chain disruptions globally.

The lack of refrigeration means the world would lose access to fresh, nutritious foods. People would be forced to rely on non-perishable, processed items. This would negatively impact health, especially for those with special dietary needs. Massive amounts of uneaten food waste would also present health hazards as it rots.

Civil Unrest

Without electricity, panic and desperation will quickly set in as people struggle to meet their basic needs. As food spoils, water services fail, and healthcare becomes unavailable, many will resort to extreme measures to survive. This dire situation is likely to lead to a breakdown of civil order, marked by widespread looting, violence, and crime.

Law enforcement capabilities will be severely hampered without communications, surveillance systems, adequate transportation or operational facilities. Jails and prisons may experience riots or mass escapes as vital security systems go down. With limited ability to maintain order or respond to emergencies, communities will be left increasingly vulnerable to unchecked lawlessness and predatory behavior.

The most vulnerable populations such as the poor, disabled, or elderly will be disproportionately impacted by the lack of essential services, healthcare, and public safety. This may spur mass migrations out of cities toward any locations perceived as safer. However, scarce resources will likely spark intense competition, hoarding behavior, and violent conflicts in nearly all populated areas.

As fear and desperation grow, the situation could devolve into widespread vigilantism and anarchy. Psychologists note that humans have an innate instinct to ensure individual survival in times of prolonged and severe crisis. If the blackout persists for weeks or longer, maintaining public safety and cohesion will become increasingly difficult.

Economic Collapse

A prolonged power outage would have a devastating impact on the economy, leading to widespread business closures, job losses, and financial market crashes. Without electricity, most businesses would be unable to operate. Manufacturing plants, stores, restaurants and other companies rely on power for production, sales, and daily functions. According to a study from Lawrence Berkeley National Laboratory, a power outage lasting one month could put over 50% of small businesses out of operation permanently (https://eta-publications.lbl.gov/sites/default/files/erss_manuscript_preprint_0.pdf).

Mass business closures would eliminate millions of jobs. One estimate suggests a four week national blackout could result in over 50 million job losses, as employees are laid off or furloughed (https://energy5.com/the-economic-impact-of-power-outages-on-businesses-and-society/). Unemployment would skyrocket, households would lose income, and consumer spending would plummet.

Financial markets and banking systems would likely crash without electricity to power trading systems and process transactions. Stock markets would be unable to operate, freezing economic activity. With commerce at a standstill, the economy would be devastated, leading to a deep recession or even depression.

Recovery Efforts

In the aftermath of a nationwide power outage, governments and communities face a tremendous task to restore order and reconnect power. According to BE PREPARED FOR A POWER OUTAGE, power companies work relentlessly to repair damage and restore power after an outage. However, it may take weeks or longer to fully restore power if there is extensive damage to power infrastructure across a wide area.

Local and state governments will mobilize police, National Guard units, and other emergency services to maintain order, provide shelter and food to displaced people, and assist with recovery efforts. The Federal Emergency Management Agency (FEMA) will coordinate with regional and local governments to bring additional resources and personnel for the recovery. According to Power Outage Tips – Nationwide, FEMA may open Disaster Recovery Centers to help connect people impacted by the outage with available aid and services.

It will likely take many months or even years to fully recover from a nationwide power outage. But through coordinated efforts across federal, state and local agencies, utilities, and communities, order can gradually be restored, infrastructure repaired, and power reconnected region-by-region.
