Many consumers are now choosing electric vehicles instead of petrol cars.
EN: In the UK, household energy costs are closely regulated by Ofgem (the energy regulator), which updates an 'Energy Price Cap' periodically. Consequently, news reports frequently discuss percentage increases in energy bills, as domestic heating and electricity expenses are a major component of the British cost of living.
EN: The verb 'predict' is followed by a that-clause acting as a noun clause (direct object) to report what is foreseen. The modal auxiliary 'could' expresses possibility rather than certainty.

EN: In the UK housing market, residential properties are predominantly categorized and marketed by the number of bedrooms (e.g., 'a three-bedroom semi-detached house', 'a four-bedroom detached') rather than by total floor area (square meters/feet), which gives an immediate sense of the home's scale and suitability for a family.
EN: The pattern 'be careful about + noun/clause' is used to express taking care or being cautious regarding a specific matter. Here, it is followed by a wh-clause ('how much energy they used') acting as the preposition's object.

EN: A restrictive relative clause introduced by 'that' is used here to define and specify the noun 'excess energy'. In this clause, 'that' functions as the direct object of the verb 'produces'.

Surplus power is fed back into the national supply system.

British suppliers like Octopus Energy frequently introduce innovative green tariffs tied to home renewable technologies such as solar and heat pumps.
EN: The 'There is / There are' structure is an existential construction used to state that something exists. Here, 'There' acts as an expletive (dummy) subject, followed by the singular linking verb 'is' because the logical subject 'one condition' is singular.

EN: "As long as" is a subordinating conjunction used to introduce a condition, meaning "only if" or "on the condition that". Like other conditional clauses (first conditional pattern), the clause introduced by "as long as" uses the present simple tense ("do") to refer to the future, while the main clause uses "will/will not" + base verb.
As long as you return the book tomorrow, you can borrow it.
EN: "Will not be billed" is a future passive construction (will + not + be + past participle). The verb "bill" means to charge someone for goods or services. Here, the subjects ("they") receive the action of being charged, so the passive voice is used.
You will not be charged any extra fees for this service.
EN: In the UK, heating and electricity bills are major concerns during winter due to cold temperatures and energy price volatility. Innovative green-energy programs (such as zero-bill guarantees via solar, batteries, and heat pumps) allow families to fix or eliminate home energy costs, provided they adhere to fair usage policies.
EN: The phrasal verb 'look forward to' means to anticipate something with pleasure. In this construction, 'to' is a preposition, not an infinitive marker, which means it must be followed by a noun, pronoun, or gerund (-ing form).
