What reflects more of the sun's energy​

cause Snow, ice, and clouds have high albedos (typically from 0.7 to 0.9) and reflect more energy than they absorb. Earth's average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space and 70 percent is absorbed. ...

Light-colored curtains can also be used to reflect rays of sunlight when the Sun is at its hottest.
