Assignment: The World’s Energy Exploration

The amount of energy available in the form of nonrenewable resources is finite. You can personally make a difference in making sure that the world continues to have enough energy to supply electricity to everyone who needs it.

a) Use renewable resources (example: adding solar panels to a building)
b) Conserve energy (example: reducing the amount of electricity used)
c) Reduce, reuse, and recycle (example: planning a recycling drive)
d) Add “green spaces” (example: growing vegetables in a garden)
