Final answer:
Wind power and solar power are two types of energy that can be used in locations without access to the energy grid.
Step-by-step explanation:
Two descriptions that correspond to systems used in locations where electrical devices cannot be connected to the energy grid are wind power and solar power. Wind power involves harnessing the energy from the wind to generate electricity, which is particularly useful in remote locations. Solar power utilizes the energy from sunlight to generate electricity, making it a suitable choice for areas with abundant sunlight.
