There are a variety of reasons why electricity may be shut off, from non-payment to reducing the risk of wildfires. While shutting off electricity does reduce the risk of fire, it also has consequences for people's health, comfort, and access to essential services. In addition, it does not necessarily reduce exposure to electromagnetic fields (EMFs) or radiation, which are created by electrical power lines, indoor lighting, and many electrical appliances. EMFs are a form of radiation that can be harmful to human health, and exposure to them is difficult to avoid, even when the power is shut off.

What You'll Learn
Electric utilities are shutting off power to more households
Electric utilities across the United States are shutting off power to a growing number of households. A report by the nonprofit Center for Biological Diversity revealed that six investor-owned utilities disconnected customers between January and September 2024 more than 662,000 times, a 20% jump from 2023. These companies included Georgia Power, DTE Energy, Duke Energy, Ameren Corporation, Pacific Gas & Electric, and Arizona Public Service.
There are several reasons why electric utilities are shutting off power to households. Firstly, it is essential to understand that electricity is getting more expensive due to lingering inflation and rate hikes. As a result, some customers are unable to keep up with the rising costs, leading to an increase in non-payments and subsequent power shutoffs. This issue is exacerbated by an "antiquated and broken" utility business model that aggressively raises rates and punishes low-income customers.
Secondly, climate change is contributing to the rise in shutoffs as extreme weather events, such as intense heat waves and wildfires, become more frequent and prolonged. In some cases, utilities may proactively shut off power to reduce the risk of wildfires during dry and windy conditions. However, this decision is not simple, as it weighs the risk of fire against the potential impact on people's health, businesses, and livelihoods.
Additionally, there are concerns about the health effects of electromagnetic fields (EMFs) created by power lines and electrical appliances. While EMF exposure in daily life is generally low, prolonged exposure to high-frequency EMFs can potentially damage DNA and cells. This concern has likely influenced the push for more distributed energy generation, such as rooftop solar and community solar projects, which reduce the need for long-distance power transmission lines.
Finally, some states have implemented temperature-based shutoff bans during extreme heat or cold to protect customers from dangerous conditions. However, these bans do not always adequately protect customers, as utilities are not required to automatically restore power to households that were disconnected prior to the ban. As a result, customers may still be left without power during extreme weather events, posing health and safety risks.

The dangers of EMF exposure
Electromagnetic fields (EMFs) are a type of radiation that has existed since the beginning of the universe, with the sun being a natural source of EMFs. Human-made sources of EMFs include electric power lines, indoor lighting, electrical appliances, and medical equipment such as X-ray and CT scan machines. While EMF exposure has been a growing public health concern, the specific dangers of EMF exposure are still a subject of debate among researchers. Here are some insights into the potential dangers:
Potential Health Risks
Most researchers agree that low-frequency EMFs pose little danger to human health. However, some scientists argue that long-term exposure to EMFs may have adverse effects on the nervous system and brain cognitive function. High levels of high-frequency EMFs are known to damage human DNA and cells, but it is unlikely that individuals will encounter such high levels in their daily lives. The International Agency for Research on Cancer (IARC) has classified non-ionizing EMFs in the radiofrequency range as a possible human carcinogen, but no mechanism by which ELF-EMFs or radiofrequency radiation could cause cancer has been identified.
Sources of EMF Exposure
EMF exposure can come from various sources, including power lines, electrical appliances, and medical devices. The use of cell phones and proximity to cell phone base stations and broadcast antennas have also been identified as contributors to EMF exposure. The strength of exposure varies based on factors such as population density, distance from the source, and time of day or day of the week.
Reducing Exposure
While complete elimination of EMF exposure is challenging due to the ubiquity of electrical devices, individuals can take steps to reduce their exposure. This includes using speakerphone or earbuds with your phone, avoiding carrying your phone in your pocket, and unplugging from electronic devices occasionally. Architectural changes to the electricity grid, such as decentralized power generation through community or rooftop solar projects, can also help reduce the need for high-voltage transmission lines, thereby decreasing EMF exposure.
Ongoing Research
The potential health consequences of EMF exposure are still being actively investigated. The World Health Organization's (WHO) International EMF Project was launched in 1996 to address public concerns and provide scientifically sound answers. Despite extensive research, there is currently no evidence to conclude that low-level EMF exposure is harmful to human health. However, the focus of international research continues to explore possible links between EMF exposure and cancer, as well as other potential health effects.

Reducing EMF exposure from household appliances
Electromagnetic fields (EMFs) are invisible energy waves generated by both natural and man-made sources. Given the proliferation of electronic devices in our homes, it's important to consider ways to reduce our exposure to EMFs. While more studies are needed to fully understand the potential health risks, it is widely recognized that prolonged exposure to EMFs can affect human well-being, causing issues such as headaches, fatigue, and anxiety. Here are some ways to reduce EMF exposure from household appliances:
Unplug Devices When Not in Use
Many household appliances, such as refrigerators, microwaves, and washing machines, continue to emit low-level EMFs even when turned off. By unplugging them when they are not in use, you can significantly reduce the overall EMF radiation in your home.
Use EMF Shielding Products
EMF shields or cases for electronic devices can block or absorb EMF radiation, reducing your exposure from high-risk devices such as mobile phones, tablets, and laptops. These devices are significant sources of EMF radiation due to their constant wireless connectivity, and prolonged use can result in increased EMF exposure.
Create an EMF-Free Zone
Designate certain areas of your home, such as your bedroom, as EMF-free zones. Avoid placing electronic devices near your sleeping area, and limit your exposure during rest periods. This will help you reduce your overall EMF exposure and improve your sleep quality.
Regularly Monitor EMF Levels
Use an EMF radiation detector, such as the Milerd HiRange, to regularly monitor and manage your exposure. This will help you identify key radiation sources in your home and make informed decisions to protect your health and the well-being of your family.
Maintain Distance from Appliances
Keep your distance from appliances, especially those that emit high levels of EMFs, such as refrigerators, microwaves, and washing machines. Avoid lingering near these appliances, and don't allow children to play or sit close to them.
Use Speakerphone or Earbuds with Your Phone
Mobile phones are a significant source of EMF radiation. By using the speaker function or earbuds, you can reduce RF exposure to your head. When not in use, place your phone away from you, preferably in another room when you sleep.
Remember, while these steps can help reduce your exposure to EMFs, it is challenging to eliminate it completely. The best approach is to be mindful of your surroundings, maintain distance when possible, and unplug or shield yourself from high-risk devices.

The impact of power shutoffs on health and safety
Power shutoffs are a last-resort safety measure to prevent wildfires. They are carried out during dangerous weather conditions to prevent power infrastructure from becoming a source of ignition. While they can reduce the risk of utility-associated wildfires, they can also have unintended consequences for people's health and safety.
Power shutoffs can leave communities and essential facilities without power, which can be life-threatening for those who depend on electricity-dependent life-sustaining equipment. It can also impact people's ability to withstand extreme heat without air conditioning. Additionally, power shutoffs can disrupt businesses and livelihoods, causing economic hardship.
To minimize the impact of power shutoffs, utilities are required to provide accurate information to customers and conduct public outreach in collaboration with community organizations and public safety partners. This includes notifying local governments, emergency officials, first responders, hospitals, and other critical infrastructure providers in advance of a potential power shutoff. Utilities must also report the number of customers notified and affected by the power shutoff.
Furthermore, power shutoffs can have indirect effects on health and safety. For example, they can disrupt the operation of medical devices and diagnostic equipment, such as X-ray imaging machines, which emit low levels of radiation. Power shutoffs can also impact the functioning of community solar projects, which can reduce the need for high-voltage transmission lines that carry power through high-risk wildlands.
Overall, while power shutoffs are an important tool for wildfire prevention, they must be carefully considered and executed to balance the risks and ensure the health and safety of communities.

Power shutoffs during extreme weather events
In recent years, there has been a growing focus on the role of power shutoffs as a preventative measure during extreme weather, particularly in reducing the risk of wildfires. In California, for example, electrical power was found to have caused 10% of all wildfires and was responsible for nearly 20% of the acres burned from 2016 to 2020. As a result, California's investor-owned utilities may initiate Public Safety Power Shutoffs (PSPS) during dangerous weather conditions to prevent their electric systems from becoming ignition sources. These decisions are based on data from fire scientists and meteorologists and are made to protect communities from the potential devastation of wildfires.
However, the decision to shut off power is not straightforward and comes with its own set of challenges. Power shutoffs can have significant impacts on people's lives and livelihoods, especially in extreme heat or cold, as they may be left without air conditioning or heating. Additionally, there are concerns for the health and safety of vulnerable populations, including older individuals and those with disabilities or specific medical conditions, who may be at greater risk during prolonged power outages.
To mitigate these challenges, utility companies often strive to balance the risks by implementing measures such as improving detection technologies and equipment, minimizing the need for electrical lines, and exploring architectural changes to the electricity grid. For instance, decentralized power generation through rooftop solar and community solar projects can reduce the need for high-voltage transmission lines that pass through wildfire-prone areas.
Ultimately, the decision to shut off power during extreme weather events involves weighing the risks of potential wildfires against the immediate consequences for affected communities. While power shutoffs can be an essential tool for wildfire prevention, they also highlight the need for more resilient and reliable electrical infrastructure that can better withstand the challenges posed by a changing climate.
