How microgrids can modernize electric grids to meet 21st-century demands

Just as having a single, outdated internet service provider leaves an area helpless in the case of an outage, failures in the electric grid can be devastating to communities. For this reason, hospitals, data centers, and other structures have their own backup power supplies. However, decentralized microgrids would provide areas with their own electricity generation and storage, thereby reducing overall grid load and reliance while enabling better electricity management.

IBM helped turn Rio de Janeiro into a smart city before it hosted the World Cup

In response to the deadly floods and mudslides in 2010, Brazil and IBM developed a multimillion-dollar plan to modernize Rio's emergency management infrastructure.

Electrical grids worldwide must double their power delivery capacity by 2050 to meet surging demand from AI and electric vehicles.

Volunteer fire departments are declining as communities shift to career staff

As populations increase and emergency calls grow more complicated, many communities are replacing volunteer fire departments with full-time professional staff—a change that boosts response capacity and reliability but also significantly raises costs.

Data centers' electrical needs create increased water demands beyond cooling

Each query uses approximately one single-serving water bottle per conversation, but water is also used for steam cycles and cooling in power plants that generate electricity for data centers. Newer cooling methods, such as immersion cooling, where servers are submerged in fluids that don't conduct electricity, can minimize water use.

Accountability can be why some people like support groups

Group camaraderie and peer support encourage people to continually connect through a support group and push participants to reflect, share, and find connection as they navigate through their lives.
