More and more, major cities across the United States are facing the compounded effects of climate change and aging infrastructure. Increased climate-related weather events, coupled with the push towards electrification, are straining already outdated systems. Today’s infrastructure is not only failing to keep pace with modern needs, but also contributing to increased risks, from fires to water losses and beyond.
A $260 Billion Investment Gap
The infrastructure in many cities across the U.S. is in need of modernization. The American Society of Civil Engineers (ASCE) gave U.S. infrastructure as a whole a grade of C- in their most recent report. While this is an improvement over a previous D+ grade, there is still much ground to cover. Today’s infrastructure investment gap continues to grow, now sitting at nearly $260 billion per year.
Electrification and a Strained Grid
The shift towards electrification, while necessary for reducing emissions, places additional pressure on the grid. U.S. electrical infrastructure, much of which was constructed in the mid-20th century, is not equipped to handle the recent surge in electrical load and increase in severe weather events. In fact, power outages from weather have roughly doubled over the past 20 years.
This aging grid is not only struggling with the increased load from things like electric vehicles and heat pumps, but is also a potential ignition point for wildfires. This is especially true in states like California, where aged power lines and extreme weather conditions have already led to increased fires. Nearly 200 fires over the past 10 years can be attributed to downed power lines in the state, including a record-breaking 41 fires in 2021 alone.
In New York City, a surge in e-bike usage has also led to more fires, many linked to the lithium-ion batteries used in these bikes. These incidents highlight the strain on the electrical grid, with just under 200 fires and 6 deaths in 2022, as reported by The New York Times.
2.1 Trillion Gallons of Water Lost
Water infrastructure in U.S. cities is also showing signs of wear. Much of the 2 million miles of water pipeline in the U.S. is reaching the end of its lifespan, having been installed in the early to mid 20th century. In many cities, water pipes are in critical condition, leading to frequent bursts and large water losses. It’s estimated that 2.1 trillion gallons of water are lost annually due to faulty infrastructure.
Investing Billions for the Future
The U.S. government is tackling some of these infrastructure concerns through the Inflation Reduction Act. Through several provisions, the IRA provides almost $2.9 billion for electrical transmission improvements. The Bipartisan Infrastructure Law allocates $50 billion to improve water infrastructure – the largest investment in water ever made by the federal government. In New York, electric company Con Edison has invested $1.5 billion in grid modernization, focusing on both upgrading the physical infrastructure and incorporating smart technology for better resilience against climate impacts. These investments are a step in the right direction, but a coordinated effort between government, businesses, and communities will likely be required to effectively manage and upgrade these systems.
Conclusion
Aging infrastructure in the face of climate change presents a complex challenge for U.S. cities. While increased electrification is a step toward sustainability, it also requires a corresponding upgrade in infrastructure to support this transition safely. Cities should balance the immediate needs for functionality with the long-term vision for sustainable, resilient infrastructure, capable of withstanding the growing pressures of a changing climate.
