SUSTAINABLECOMMUNITIES
ECOLOGICAL FOOTPRINT:
The effect that a person, business, activity, or community has on the environment.
SUSTAINABLECOMMUNITIES:Communities that are planned, built, or modified to encourage
sustainable living; usually designed so inhabitants can generate
minimal environmental impact while maintaining a strong
economy.
RENEWABLE ENERGY:Energy from sources that naturally renew, or will not run out in our lifetimes.
SOLAR ENERGY:Solar energy relies on power drawn from the sun. It is usually divided into two types: active solar energy and passive solar energy.
ACTIVE SOLAR ENERGY:
Using technology like solar panels to collect energy from the sun and convert it to electricity.
PASSIVE SOLAR ENERGY
Does not rely on technology but takes advantage of the way the sun naturally
interacts with the earth.
GREEN ROOF:
Another form of passive solar technology; green roofs are covered with plants, which
help keep the building warm.
WIND ENERGY:
Wind turbines like these convert wind energy into electricity to supply
communities with power.
GEOTHERMAL ENERGY:
Draws on the superhot temperatures below Earth’s surface by tapping into
steam vents, geysers, and even magma deep underground.
BIOMASS ENERGY:
Energy from plants or other organic
material, like garbage. It can be
converted to biogas, which has a variety of uses.
HYDROELECTRICITY:Hydroelectric power is made by flowing
water. People control the flow of water by building dams on rivers. As the dam
releases water, it creates electricity that can be used by thousands of people.
