The main reason power lines are not underground is cost. Burying electrical cables is typically 3 3 to 14 14 times more expensive than installing overhead lines. These massive costs—often hundreds of thousands of dollars per block—would ultimately be passed down to customers and taxpayers.
The main reason that utility companies will not bury power lines underground is cost. Research shows that the price for running a typical overhead power cable is approximately $100,000 per mile and that the price for burying those same wires underground would increase by 10 times or more.
Burying power lines is expensive.
Since underground lines can't release heat the way overhead lines can, that excess heat must be managed to avoid overloads. This requires the use of higher-cost conductors and other insulating infrastructure.
LA: It can cost $400,000 per mile in Michigan to bury existing lines, utilities say. It requires tearing up roads.
All 2,200 miles of our higher-voltage lines are overhead because building them underground can dramatically increase costs. Burying power lines is expensive. It can cost significantly more to install facilities underground, and that premium is even greater for higher-voltage projects.
Squirrels don’t get electrocuted on power lines because electricity always seeks the path of least resistance to the ground. As long as an animal touches only one wire, no electrical current flows through its body. However, if they bridge the gap between two different lines or a wire and a grounded object, they create a circuit that results in electrocution.
While underground lines tend to be more reliable and less likely to experience an outage, they generally also have a higher installation cost than an overhead line. Moreover, when there is an outage, the problem is often 3 feet or more below ground.
Louisiana and Maine consistently rank as the states with the worst power grids based on the duration and frequency of outages. Louisiana experiences the longest average blackout times—often exceeding 400 minutes per customer—due to frequent hurricanes, while Maine records the highest number of annual outages due to heavy forestation and harsh winter weather.
Yes, there is still a massive amount of copper in Michigan, mostly concentrated in the western Upper Peninsula. In fact, this region contains the only deposits in the world where copper formed as pure, native metallic chunks rather than locked inside minerals.
Never trim trees near electric lines!
Tree limbs or other vegetation that grow on utility poles and into power lines can cause fires, power outages, and damage your equipment or property. To increase safety and minimize outages, we routinely trim tree limbs and vines around our poles and lines.
Underground cable contains insulation material which has a design life of 30 to 40 years. Overhead lines are designed to provide safe insulation using glass, porcelain and physical air space. These materials have a design life of 80 to 100 years.
California. In the United States, the California Public Utilities Commission (CPUC) Rule 20 permits the undergrounding of electrical power cables under certain situations.
Now Vector is defending the lower priority it is giving to burying existing power lines, saying the cost – which averages $10,000 to $15,000 per property – is not always the best bang for the buck.
Those large orange balls are called aerial marker balls, and they serve as vital safety warnings for pilots. Because thin electrical wires can easily blend into the sky, mountains, or valleys, these markers make the lines highly visible to prevent collisions with helicopters and low-flying planes.
Traditionally, the province sends power to California; however, in 2023 California received less power from British Columbia because California's renewable power capacity increased in 2023 and hydropower generation increased by 80% compared with 2022 when there was a persistent drought in California.
This trend is driven by the belief that copper's value will continue to rise, making it a profitable asset to hold onto. As a result, large quantities of copper, especially in the form of scrap metal, have been stockpiled, creating shortages in the market.
Arizona: The Copper State
Arizona rightfully claims its nickname as "The Copper State," dominating U.S. production with an impressive 700 million pounds annually, representing approximately 71% of all domestic copper production.
The world has about 40 years of copper left in current identified reserves, and over 200 years of total resources. Because copper is 100% recyclable without losing its properties and the industry discovers new deposits over time, humanity is highly unlikely to ever run out completely.
China consumes by far the most electricity of any country in the world, with almost 9,000 terawatt-hours equivalent consumed in 2024.
The best states for off-grid living balance affordable land, a favorable climate for renewable energy, and relaxed building or permitting laws. Top choices include Tennessee (abundant rainfall/mild winters), Missouri (lax building codes in rural areas), New Mexico (low regulations/abundant solar), and Texas (cheap acreage).
Yes, you can usually flush a standard gravity toilet during a power outage. Since these toilets rely on gravity rather than electricity to push water down the drain, they will continue to work as long as water is flowing into your home.
Birds survive on power lines because they only touch one wire, meaning no electrical circuit is created. Electricity requires a path of least resistance to flow to an area of lower voltage (like the ground). If you touch a power line, your body bridges the gap between the wire and the ground, creating a deadly circuit.
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
The sun could similarly destroy all or parts of the system through a natural event. An electromagnetic pulse (EMP) is the electromagnetic radiation from a nuclear explosion caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the nuclear device or a surrounding medium.
