Question 2 • Grade 8 World Cultures and Geography A
Answer:
Three technologies or products that can help conserve energy are LED light bulbs, smart thermostats, and energy-efficient appliances. LEDs use much less electricity than traditional incandescent bulbs and last longer. A smart thermostat can adjust heating and cooling when people are away or asleep. Efficient refrigerators, washing machines, and other appliances use less electricity or water while doing the same jobs as older models.
