In the subconscious of many people, America symbolizes prosperity and strength, attracting individuals from all over the world to pursue their dreams, and this situation is no exception in China.
Many people aspire to become American citizens, and this yearning seems inevitable under the widespread influence of American culture.
The United States and China, as the two major powers of the East and West, are often compared, as there are significant differences between the two countries in many aspects.
Even the materials of the utility poles on both sides of the streets differ.
In the United States, utility poles are primarily made of wood, usually using local plants such as fir trees;
Whereas in China, utility poles are generally made of concrete.
This phenomenon reflects the different philosophies of infrastructure construction and resource utilization in the two countries.
So, why does the United States prefer to use wooden utility poles?
The difference in utility pole materials between China and the United States reflects, to some extent, the respective national conditions and resource situations of the two countries.
Due to geographic location and historical cultural differences, the two countries exhibit significant differences in the details of infrastructure construction.
The reason the United States primarily uses wooden utility poles is because of its abundant natural resources, especially forestry resources.
The U.S. territory has vast forest coverage, with about one-third of the land occupied by forests, mainly consisting of tall fir and pine trees, which are very suitable for use as raw materials for utility poles.
Tracing back to the early 20th century, electricity, as an emerging energy source, gradually gained global acceptance, and the U.S. began to popularize electrical systems at this time.
To save costs, wood became an economical choice, similar to how rural China used mud to build houses in the last century to quickly promote electrical infrastructure.
The advantages of wooden utility poles include high output, easy transportation, and simple installation, which make construction workers more inclined to use wood.
Additionally, wooden utility poles align with environmental protection concepts, and if there are issues later, they can be recycled.
Thus, even though some suggest using concrete utility poles, this proposal often meets resistance.
The privatization of the electrical system in the U.S. also encourages companies to prioritize the cost-effective option of wood.
In contrast, concrete utility poles not only have a higher cost, but installation fees are also more expensive, which does not meet the profit needs of companies.
Moreover, due to the sparse population in the U.S., using concrete utility poles would incur higher costs, making wooden poles still sufficient for daily needs.
In China, the material of utility poles is closely related to national conditions.
Our country's forest resources are relatively scarce, and influenced by the concept that "green mountains and clear waters are as valuable as mountains of gold and silver," protecting the ecological environment is a primary task.
Therefore, wooden utility poles do not meet our environmental protection standards, while materials like concrete have become the preferred choice due to their high output.
With a large population density in China, using wooden utility poles may struggle to meet electricity demands and exacerbate the reduction of natural resources.
As a "mania" for infrastructure construction, our country prioritizes quality and stability in the construction process, while being relatively flexible on costs.
State-led electrical system construction ensures the stability of electricity supply, which is crucial for rapid economic development.
With the advancement of ultra-high voltage transmission technology, China's requirements for the strength of utility poles continue to rise, making wooden utility poles unable to meet this demand.
Therefore, reinforced concrete utility poles have become a necessary condition for supporting ultra-high voltage transmission.
Utility poles of different materials each have their pros and cons.
Wooden utility poles have a cost advantage but are at a disadvantage in other aspects such as lifespan.
Wooden poles are easily affected by external environmental factors; rain and corrosion can shorten their lifespan, which typically requires replacement after about 25 years.
In contrast, the lifespan of concrete utility poles can reach 50 to 100 years, and with technological advancements, their service life may further extend.
The strength and durability of concrete utility poles give them an advantage in long-term use, as they only require regular maintenance after installation, reducing later costs.
Concrete utility poles are less susceptible to issues like rain corrosion or pest damage, thus making them more reliable for modern development needs.
Additionally, wooden utility poles have weak resistance to natural disasters, being flammable and performing poorly in situations like typhoons or earthquakes.
In comparison, concrete utility poles are better able to maintain their functionality when facing natural disasters such as fires and floods.
This is one of the reasons many countries choose concrete as the material for utility poles.
As the world's largest economy, the United States has a strong economic development momentum and is fully capable of upgrading wooden utility poles to more advanced concrete ones.
However, the streets of America are still filled with a large number of wooden utility poles, which are often old and damaged, posing risks to both aesthetics and safety.
In the event of natural disasters like earthquakes, the entire electrical system could become paralyzed, making reconstruction even more difficult.
This situation constrains the development of the United States; although some insightful individuals call for change, this status quo is deeply entrenched and challenging to alter.
U.S. law stipulates that the government must obtain congressional approval to use treasury funds, making the substantial funding required to replace utility poles a significant limitation for governments at all levels.
In the context of privatization of the electrical system, companies focus more on short-term profits rather than long-term infrastructure updates.
In contrast, as China's economy rapidly develops, electricity demand increases year by year, necessitating stronger and more durable electrical infrastructure.
As early as the 1950s, our country began researching the production and application of concrete utility poles.
After years of development, China has established a mature system for the construction and maintenance of utility poles.
Today, China has become the world's largest producer and consumer of concrete, with ample supply and strong demand complementing each other, allowing concrete utility poles to be spread across the country, providing stable electricity assurance for residents.
Currently, our country is at the forefront of global electricity development, with continuously improving infrastructure levels and strong development potential.
American wooden utility poles seem somewhat out of place in the trend of modernization, which is influenced both by national systems and social structures.
