How can IoT help combat climate change?

• A. Smart devices working to reduce energy use.
• B. Prevention of methane release from cows.
• C. Free internet in cities to help people operate in the city more easily.
• D. Predictive maintenance of wind turbines, preventing burn out.

Answer: (A)

IoT helps combat climate change by making energy use smarter and more efficient across homes and buildings. Connected sensors and controls automate actions like turning lights off when spaces are empty, optimizing heating and cooling, and scheduling high-energy appliances to run during cheaper or cleaner times. This directly lowers electricity demand, reducing emissions from power plants, and makes it easier to run on renewable energy sources. While keeping wind turbines well maintained supports reliable renewable supply, the strongest climate impact comes from IoT-enabled efficiency that cuts energy use across many devices and sectors. Other options touch on narrower areas, but they don’t deliver the broad, direct emissions reductions that energy optimization does.
