Question

Responses

Energy from the sun might be greater than the energy needs of the house because some energy is destroyed in the process.
Energy from the sun might be greater than the energy needs of the house because some energy is destroyed in the process.

Energy from the sun might be less than the energy needs of the house, but solar cells make up for this difference.
Energy from the sun might be less than the energy needs of the house, but solar cells make up for this difference.

Energy from the sun might be greater than the energy needs of the house, so some energy will be stored and/or wasted.
Energy from the sun might be greater than the energy needs of the house, so some energy will be stored and/or wasted.

Energy from the sun will equal the energy needs of the house because energy is not created or destroyed.

Answer 1

Energy from the sun might be greater than the energy needs of the house, so some energy will be stored and/or wasted.
