Key Concepts
• There are many different things we can do—as individuals, families,
utility companies, municipalities, and society as a whole—to reduce
water consumption, from reducing the lengths of showers to choosing
foods that require less water to grow.
• By collecting rainwater in rain gardens, bioswales, or cisterns, or as
groundwater, we keep it from becoming wastewater.
• It is important that we protect our water, power, and sewer resources
from contamination, vandalism, and other human-induced threats.
• Energy conservation and energy efficiency are two different approaches
to saving energy: Energy conservation is a change in behavior that results
in using less energy, while energy efficiency is a technological approach
that requires less energy to perform the same function.
