The business secretary said that the UK government's efforts to build new nuclear power plants may increase people's energy bills in the short-term.
There might be a small effect on bills under the new model.
Nuclear would provide cheaper power and energy security in the long-term, he said.
He said financial help had been offered.
Mr Kwarteng said that nothing should be taken off the table, including a windfall tax on the excess profits of oil and gas companies.
The government has pledged to build a new nuclear power station in north Wales, and Mr Kwarteng spoke to the BBC about it.
Prime Minister Boris Johnson said last month that he wanted to revive the idea of a new nuclear power station.
Nuclear power is one of the key focuses of the energy strategy released in April.
Nuclear, wind and hydrogen power are some of the alternative sources of energy the government plans to invest in.
There is an ambition to deliver up to eight new nuclear reactors before the year 2030.
25% of the UK's predicted energy demand will be supplied by nuclear by the year 2050.
Mr Kwarteng said that investing in nuclear was part of the solution to the UK's energy needs.
Nuclear is back on the table because it provides more decarbonised power and a sustainable energy source.
Nuclear power plants can be much more expensive than renewables and can take a long time to build.
A new law allows for a small surcharge to be added to people's bills during the construction of a nuclear reactor.
The government says this will lead to savings for consumers in the long run, as developers can have more money upfront, and are less likely to take out loans.
Critics argue that this shifts the risk of building a new nuclear reactor onto the consumer, without knowing how long the project will take or how much it will cost.
Mr Kwarteng said that putting bills up in the short-term was worth the political risk. People here really want to see new investment, jobs, and opportunity for their kids.
The government's own public attitudes research shows that people support renewable energy at a lower rate than nuclear energy.
Nuclear plants are more expensive to build than other forms of power.
The cost of the new nuclear power station is expected to be 22-26 billion.
When asked if the public supported investment in nuclear, the business secretary said it was more popular now than it has been in the past.
He said there were two reasons why we want to see more nuclear - security of supply here in the UK and what experts call firm power.
If you look at renewable energy, the sun doesn't always shine and the wind doesn't always blow.
He said that there is broad public support in a community like WylFA.
Nuclear power won't be everywhere in the UK, but it will be on sites with a history.
Local people have differing opinions on the government's plan for a new nuclear power station.
Jo said she reluctantly accepted that investing in nuclear power was necessary.
She said that you can't say that you don't want nuclear power, because what else are you going to have?
Emlyn Richards, a retired Methodist minister, was less enthusiastic about the idea.
He said thatAnglesey is noted for its wind.
He said Wylfa was the most beautiful spot on the island.
The government opened a 120 million dollar fund on Friday to encourage the development of nuclear technologies.
Small nuclear reactor (SMRs), which are smaller and can be assembled in factories, are being supported by the government as well as large traditional nuclear reactor.
The CEO of Rolls Royce said they wanted to finance their SMRs through a combination of private and government financing.
It is a better way to keep consumers costs low.
He said that the government's model of funding nuclear projects, which can add levies to people's bills while they are in construction, would reduce the costs of delivering nuclear projects.
He said that they have to find ways to finance that build most economically.
