Questions1.What

form

of

energy

do

is

classified

as

energy

that

comes

from

resources

like

sunlight(known

Questions1

Is

it

important

to

conserve

energy?Why

do

you

think

so?TipsYes,

it's

definitely

important

to

conserve

energy.

There

are

several

reasons.

First,

it

reduces

our

consumption

of

fossil

fuels

which

have

a

fixedquantity

of

availability

and

are

rapidlydiminishing.

Second,

it

saves

us

moneybecause

we

don't

have

to

build

more

powerplants.

Third,

it

reduces

carbon

emission,

whichwill

contribute

greatly

to

the

improvement

of

our

air

quality

and

natural

environment.Discussion

QuestionsThere

are

many

other

things

we

can

do

to

save

energy,

such

as:·

Not

to

overheat

or

overcool

our

rooms.·

Reduce

the

amount

of

we

produce

bybuying
