बिजली है और बालकनी में धूप है, लेकिन बाहर शोर है।

Because Hindi often states each clause separately.

This sentence has three linked parts:

• बिजली है = There is electricity.
• बालकनी में धूप है = There is sunlight in the balcony.
• बाहर शोर है = There is noise outside.

In English, you might sometimes avoid repeating is, but in Hindi it is very normal to repeat है in each clause.

Here, बिजली है means there is electricity or the power is on.

A useful point: बिजली can mean:

• electricity
• electrical power
• sometimes lightning, depending on context

In this sentence, it clearly means electricity/power, not lightning.

Hindi does not always need a separate word for there is/there are the way English often does.

So:

• बिजली है literally looks like electricity is
• but naturally means there is electricity

Hindi often expresses existence this way: noun + है

Examples:

• पानी है = There is water.
• समय है = There is time.
• शोर है = There is noise.

में is a postposition meaning in, inside, or sometimes within.

So:

• बालकनी = balcony
• बालकनी में = in the balcony / on the balcony

Even though English usually says on the balcony, Hindi commonly uses में here.

That is very normal. Hindi often uses में in places where English might use in, on, or even another preposition.

Hindi often prefers an existence-style expression:

• बालकनी में धूप है = There is sunlight in the balcony

English may choose an adjective-based sentence like The balcony is sunny, but Hindi commonly uses a noun like धूप (sunlight/sunshine) plus है.

So this structure is very natural in Hindi.

धूप means sunlight, sunshine, or direct sun.

It usually refers to sun exposure rather than just daylight in general.

So:

• धूप है = there is sunshine / the sun is coming in
• धूप में = in the sun

In this sentence, बालकनी में धूप है suggests that the balcony is getting sunlight.

बाहर means outside.

In many cases, बाहर can work on its own as an adverb of place, so:

• बाहर शोर है = There is noise outside

You may also hear बाहर में in some regional speech, but standard Hindi usually just uses बाहर by itself in sentences like this.

Compare:

• अंदर लोग हैं। = There are people inside.
• बाहर शोर है। = There is noise outside.

शोर means noise, loud sound, or commotion.

Like English noise, it is usually treated as an uncountable idea rather than something countable.

So:

• शोर है = there is noise
• बहुत शोर है = there is a lot of noise

You would not normally treat it like a noise in basic usage.

They connect different parts of the sentence in different ways:

• और = and
• लेकिन = but

So the sentence is structured like this:

• बिजली है और बालकनी में धूप है
• लेकिन बाहर शोर है

That means the first two facts are simply added together, and the last one is presented as a contrast.

Yes, it is normal.

Hindi often uses this order:

• place + thing + है
• or simply thing + है

So:

• बालकनी में धूप है = In the balcony, there is sunlight
• बाहर शोर है = Outside, there is noise

This may feel different from English, but it is a very common Hindi pattern.

In the present tense with है, you do not see much visible agreement in this kind of sentence.

For singular subjects, है stays है whether the noun is masculine or feminine:

• धूप है
• बिजली है
• शोर है

So even though धूप and बिजली are feminine nouns, the verb here is still just है.

You see gender agreement more clearly in adjectives or in other tenses/forms.

It is a borrowed word, ultimately from English balcony, but it is commonly used in modern Hindi.

Hindi uses many borrowed everyday words, especially for modern objects and places. So बालकनी is completely natural.

Learners should get comfortable with the fact that Hindi mixes:

• native Sanskrit/Prakrit-origin words
• Persian/Arabic-origin words
• English loanwords

Yes, but the original version is clear and natural.

For example, you could hear simpler spoken variants depending on context, but:

बिजली है और बालकनी में धूप है, लेकिन बाहर शोर है।

is perfectly fine because each condition is clearly stated.

For learners, this full structure is especially helpful because it makes the grammar easy to see.

For plural nouns, है usually changes to हैं.

For example:

• बाहर लोग हैं। = There are people outside.
• कमरे में कुर्सियाँ हैं। = There are chairs in the room.

But with mass nouns like शोर and बिजली, Hindi normally keeps them singular in meaning:

• शोर है
• बिजली है

So in your sentence, है is correct.

Yes. Common alternatives include:

• पर = but
• मगर = but
• लेकिन = but/however

So you could also say:

• बिजली है और बालकनी में धूप है, पर बाहर शोर है।
• बिजली है और बालकनी में धूप है, मगर बाहर शोर है।

All are natural, though लेकिन is a very standard textbook-friendly choice.
