When

was

Energy

for

Today

and

Tomorrow

Did

you

know

that

most

of

the

energy

we

use

comes

from

the

sun?

For

example,

the

sun

helps

plants

to

grow.

Plants

that

grew

millions

of

years

ago

turned

into

coal,

oil,

and

natural

gas

（天然气）.

We

call

these

fossil

fuels

（化石燃料）.

However,

fossil

fuels

make

pollution.

This

is

bad

for

the

Earth.

Fossil

fuels

are

also

nonrenewable.

Some

day

they

will

be

gone.

So,

scientists

want

people

to

use

green

energy.

Why

is

green

energy

important?

First,

it

is

clean.

It

doesn't

hurt

the

Earth.

Next,

it

is

renewable.

It

won't

run

out.

Green

energy

gives

us

almost

25%

of

the

electricity

we

use

today.

What

are

the

main

sources

（来源）

of

green

energy?

Water

Water

uses

moving

power

makes

16.6%

of

the

electricity

we

use.

Wind

Power

Is

wind

power

new?

No,

it

isn't.

People

used

wind

power

many

years

ago.

Wind

power

makes

4%

of

the

we

use.

Solar

Power

Solar

power

comes

from

sunlight.

The

sun

shines

on

solar

panels

（太阳能板）,

and

electricity

is

made.

Solar

power

is

now

as

cheap

as

some

fossil

It

makes

1.5%

of

the

electricity

we

use

Biomass

（生物质能）

Biomass

is

energy

that

we

get

from

plants

around

us.

For

example,

dead

wood

or

grass

is

burned

in

power

stations.

This

makes

electricity.

Biomass

is

green

energy

because

we

under

the

Scientists

can

which

is

called

We

may

of

In

was

born

in

Guangxi

but

raised

in

Sanya,

has

made

great

efforts

to

protect

the

of

Sanya

city

in

Hainan.

He

is

now

spreading

the

knowledge

of

environmental

protection

through

new

platforms

（媒体平台）.

Around

he

began

doing

volunteer

work

to

clear

rubbish

from

the

beaches

and

officially

registered

in

2017.

Li

Jin

immediately

took

the

lead

in

a

cleanup

activity

on

the

Sanya

River.

In

April,

2021,

he

used

his

own

money

to

set

up

a

volunteer

service

center

which

has

1,170

registered

members

who

take

part

in

activities

without

for

They've

drawn

the

attention

has

organized

51

activities

that

have

In

the

government

invited

him

to

make

a

number

of

short

videos,

in

which

he

uses

simple

to

explain

how

to

protect

Several

of

have

been

watched

“My

Plastic

brings

us

convenience,

and

pollution

as

well.

1.___

It's

in

our

food

and

drinks,

in

the

clothes

we

wear

and

even

in

the

air

we

breathe.

Some

very

tiny

pieces

of

plastic

are

called

microplastics

（微塑料）.

The

largest

microplastics

can

be

directly

seen.

2.___

What

should

we

do

then?3.___

Any

time

plastic

boxes

are

heated,

microplastics

can

get

into

your

If

you

can't

avoid

using

plastic

boxes,

try

not

to

heat

food

in

them.AFB

Use

a

glass

or

metal

cup

instead

of

a

plastic

one.

Researchers

have

found

that

bottled

has

more

microplastics

than

4.___

So

if

like

drinking

coffee,

milk

or

other

hot

drinks,

remember

to

use

that

should

be

careful

with

possible

microplastics

in

life.
