Tento způsob sníží spotřebu energie.

Yes. Tento means this.

In tento způsob, tento matches způsob in:

• gender: masculine inanimate
• number: singular
• case: nominative

So tento způsob = this method / this way.

A useful comparison:

• ten způsob = that method or sometimes just the method, depending on context
• tento způsob = this method, a bit more specific or formal

In everyday spoken Czech, people often say tenhle způsob instead of tento způsob.

Způsob means method, way, or means.

In this sentence, it refers to a way of doing something:

• Tento způsob = This method / This way

It is a masculine inanimate noun.

Other examples:

• jiný způsob = another method
• dobrý způsob = a good way
• způsob práce = method of work

Here způsob is the subject of the sentence, so it is in the nominative singular.

The sentence structure is:

• Tento způsob = subject
• sníží = verb
• spotřebu energie = object

Because způsob is the thing doing the action, it stays in the nominative:

• Tento způsob sníží... = This method will reduce...

This is a very common Czech point.

Sníží is from the verb snížit, which is a perfective verb. In Czech, perfective verbs do not normally have a true present meaning. Their present-form endings are used to express the future.

So:

• snížit = to reduce (perfective, completed action)
• sníží = he/she/it will reduce

In this sentence:

• Tento způsob sníží spotřebu energie.
• literally: This method will reduce energy consumption.

If you wanted an ongoing or repeated meaning, Czech would usually use the imperfective verb snižovat:

• snižuje = is reducing / reduces
• bude snižovat = will be reducing

Because the subject is tento způsob, which is:

• third person
• singular

So the verb must agree with it:

• já snížím = I will reduce
• ty snížíš = you will reduce
• on/ona/ono sníží = he/she/it will reduce

Since způsob is grammatically like it, Czech uses:

• Tento způsob sníží...

Because spotřeba is the direct object of the verb sníží.

The basic dictionary form is:

• spotřeba = consumption

But after a transitive verb like snížit (to reduce), the direct object goes into the accusative case.

So:

• nominative: spotřeba
• accusative: spotřebu

That is why the sentence has:

• sníží spotřebu = will reduce consumption

Here energie is in the genitive.

The phrase spotřeba energie means:

• consumption of energy
• more naturally in English: energy consumption

So the structure is:

• spotřeba = consumption
• energie = of energy

This is very common in Czech: one noun is followed by another noun in the genitive to show a relationship.

Examples:

• cena auta = the price of the car
• spotřeba paliva = fuel consumption
• výroba elektřiny = production of electricity

So:

• spotřebu energie = energy consumption in the accusative + genitive structure

Here it is understood as singular: energy.

Formally, energie can look ambiguous because some Czech noun forms are identical in different cases or numbers. But in this sentence, the meaning and grammar clearly point to genitive singular:

• spotřeba energie = consumption of energy

That is the normal way to say energy consumption.

Yes. Czech word order is more flexible than English because case endings show grammatical roles.

The neutral order here is:

• Tento způsob sníží spotřebu energie.

But other orders are possible for emphasis, for example:

• Spotřebu energie tento způsob sníží.
• Tento způsob spotřebu energie sníží.

These alternatives may sound more marked, stylistic, or context-dependent. For a learner, the original sentence is the safest and most neutral version.

It is natural, but it sounds a bit more neutral-written or formal than everyday casual speech.

Possible variants:

• tento způsob = neutral, clear, slightly formal
• tenhle způsob = common spoken Czech
• ten způsob = also common, depending on context

So in a technical text, article, or presentation, tento způsob is very normal.

A rough pronunciation guide is:

• sníží ≈ snee-zhee

A few details:

• sn is pronounced together at the start
• í is a long ee sound
• ž sounds like the s in measure or vision
• the final í is again long

So the word has two long vowels:

• s-ní-ží

Yes, absolutely.

That means basically the same thing:

• Tato metoda sníží spotřebu energie.
• This method will reduce energy consumption.

The difference is mostly lexical:

• způsob = way, method, manner
• metoda = method, often a bit more technical or systematic

So způsob can feel broader, while metoda can sound more specifically like a defined method or procedure. Both are correct in many contexts.
