Even as people are suffering through the harshest winter storm Texas has seen in decades, the reasons for the state’s devastating power grid failure have become a political battleground. While vulnerable people freeze in their homes, pundits snipe about whether wind turbines are to blame. Tiếp tục đọc “Lessons from Texas Freeze: 5 Ways to Strengthen US Energy Resilience”

Every other month the news seems to flash images of extreme weather – disastrous heat waves, floods of biblical proportions, and epic storms. On the rise as a result of a changing climate, these weather events can cause a myriad of damages and put the world’s critical infrastructure at risk. This costs money. The devastating 2010 floods in Pakistan caused close to $2 billion in damages to physical infrastructure, according to World Bank estimates. And Hurricane Sandy wreaked $1.13 billion in damages on New York City’s infrastructure alone (New Jersey and other parts of New York State saw significant damages as well).
Examples like these are endless.
Alongside these increasing climatic risks to the world’s existing infrastructure assets, the fact remains that many countries desperately need more and better infrastructure. This is particularly true for developing countries. To meet the future infrastructure demands of these economies would require investment of at least an estimated additional $1 trillion a year through 2020.

Designing resilient infrastructure systems will require collaborative efforts by engineers and social scientists.
Urban societies depend heavily on the proper functioning of infrastructure systems such as electric power, potable water, and transportation networks. Normally invisible, this reliance becomes painfully evident when infrastructure systems fail during disasters. Moreover, because of the network properties of infrastructure, damage in one location can disrupt service in an extensive geographic area. The societal disruption caused by infrastructure failures is therefore disproportionately high in relation to actual physical damage. Tiếp tục đọc “Infrastructure Resilience to Disasters”
