Internet of Things (IoT) Practice Exam

How can IoT help combat climate change?

1. Smart devices working to reduce energy use.

2. Prevention of methane release from cows.

3. Free internet in cities to help people operate in the city more easily.

4. Predictive maintenance of wind turbines, preventing burn out.

The correct answer is: Smart devices working to reduce energy use.

The involvement of IoT in helping combat climate change is significantly illustrated through the functionality of smart devices designed to optimize energy consumption. These smart devices, which can include smart thermostats, smart lighting systems, and energy management tools, utilize real-time data to adjust usage based on current conditions and user behavior. This real-time monitoring and automation lead to a reduction in overall energy consumption and greenhouse gas emissions. For instance, in residential settings, smart thermostats learn user patterns and can adjust heating and cooling systems to minimize usage when homes are unoccupied, leading to lower electricity bills and less strain on power plants. Similarly, in commercial buildings, IoT systems can manage lighting, heating, and cooling based on occupancy levels and external weather conditions, achieving significant energy savings. This proactive approach not only reduces the carbon footprint associated with energy generation but also promotes a sustainable lifestyle by encouraging more efficient use of resources. By facilitating energy savings on a broad scale, IoT provides a vital tool in the fight against climate change.
