The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
I would just survey whoever is in my house. And I will be honest I have no idea what the survey is about but obviously your school (k12 maybe?) would not expect you to go around the neighborhood asking random people where their knuckle hair is located. All I can say Is try your best. Hope this helped. XD
