THE ENERGY WE USE TO LIGHT OUR
HOMES, HEAT OUR SCHOOLS, AND RUN

OUR CARS, COMES FROM MANY SOURCES.

COAL, NATURAL GAS, AND OIL ARE CALLED NONRENEWABLE ENERGY

SOURCES BECAUSE ONCE WE USE THEM UP, THERE WON'T BE ANY LEFT.

THESE STANDARD SOURCES PROVIDE
DEPENDABLE ENERGY.

BUT THESE NONRENEWABLE ENERGY
SOURCES ADD POLLUTANTS TO THE

AIR, INCREASE GLOBAL WARMING AND
CLIMATE CHANGE, AND MANY ARE

HARD ON THE ENVIRONMENT.

SO MORE AND MORE PEOPLE ARE LOOK
AT DIFFERENT WAYS TO GET THEIR

ENERGY.

GREEN ENERGY SOURCES ARE
RENEWABLE, GENERALLY DON'T

CONTRIBUTE TO GLOBAL WARMING,
AND ARE MORE ENVIRONMENTALLY

FRIENDLY.

HERE'S SOME EXAMPLES OF GREEN
ENERGY.

SOLAR POWER CAPTURES ENERGY FROM
THE SUN.

THESE TURBINES CREATE
ELECTRICITY WITH WIND POWER.

HYDROELECTRIC ENERGY IS CREATED
WHETHER WATER FLOWS THROUGH

TURBINES TO MAKE ELECTRICITY.

GEOTHERMAL HEAT, THAT IS HOT
WATER FROM DEEP WITHIN THE

EARTH, CAN BE USED AS AN ENERGY
SOURCE.

A NUMBER OF BUILDINGS IN BOISE
ARE ALREADY HEATED WITH

GEOTHERMAL ENERGY.

OTHER GREEN ENERGY SOURCES
INCLUDE USING TIDAL WAVES IN THE

OCEAN, OR BURNING WASTE OR
PLANTS TO CREATE ELECTRICITY.

NUCLEAR POWER COULD ALSO BE
CONSIDERED GREEN ENERGY.

AND THERE'S ONE OTHER IMPORTANT KIND OF GREEN ENERGY THAT YOU

CAN DO SOMETHING ABOUT.

CONSERVING ENERGY OR USING LESS ENERGY IS THE EASIEST AND

CHEAPEST WAY TO HELP THE ENVIRONMENT.

THERE ARE SOME SIMPLE THINGS YOU
CAN DO TO SAVE ENERGY.

TURN OFF THE LIGHTS WHEN YOU
LEAVE A ROOM.

SET THE THERMOSTAT AT NO MORE
THAN 68 DEGREES IN THE WINTER,

OR NO LESS THAN 78 DEGREES IN
THE SUMMER.

WALK TO SCHOOL.

RECYCLE.

AND CHANGE INCANDESCENT LIGHT
BULBS TO COMPACT FLUORESCENT

LIGHTS.

IF WE CONSERVE ENERGY AND
CONTINUE TO IMPROVE GREEN ENERGY

SOURCES, THEN THE EARTH'S FUTURE
WILL STAY BRIGHTER TOO.
