The sun will enter this phase of its life as it ages and the hydrogen/helium reaction reduces. See the Wikipedia extract as follows. There are also articles on Red Giant and Asymptotic Giant Branch stars in Wikipedia
When a star exhausts the supply of hydrogen by nuclear fusion processes in its core, the core contracts and its temperature increases, causing the outer layers of the star to expand and cool. The star's luminosity increases greatly, and it becomes a red giant, following a track leading into the upper-right hand corner of the HR diagram. Eventually, once the temperature in the core has reached approximately 3x108K, helium burning begins. The onset of helium burning in the core halts the star's cooling and increase in luminosity, and the star instead moves back towards the left hand side of the HR diagram. This is the horizontal branch (for population II stars) or red clump (for population I stars). After the completion of helium burning in the core, the star again moves to the right and upwards on the diagram. Its path is almost aligned with its previous red giant track, hence the name asymptotic giant branch. Stars at this stage of stellar evolution are known as AGB stars
The Sun energy is from hydrogen fusion.
Scientists hope to generate electricity and heat through nuclear fusion as well as nuclear fission.
In nuclear physics and nuclear chemistry, nuclear fusionis the process by which multiple like-charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy.
They generate electrical energy from nuclear energy, and then distribute it through wires to your house, where it can be used to run your lights, your TV, and your electric can-opener.
The job of nuclear power plants is to generate electricity by using nuclear reactions to produce steam, which drives turbines to generate power. Nuclear reactors convert nuclear energy into heat energy, which is then used to create steam through a heat exchanger, ultimately producing electricity.
The Sun energy is from hydrogen fusion.
The Sun generates its energy through nuclear fusion in its core. Hydrogen atoms combine under extreme heat and pressure to form helium, releasing a large amount of energy in the process. This energy is what powers the Sun and allows it to emit light and heat.
Through nuclear fusion of hydrogen to form helium
We derive electromagnetic energy from the nuclear fusion reactions on the sun. We also apply nuclear energy (fission) on earth to generate lots of thermal energy, which we use in a steam cycle to generate lots of electric power.

The Sun's energy comes from nuclear fusion reactions happening in its core. These reactions convert hydrogen into helium, releasing vast amounts of energy in the form of light and heat. This process has been ongoing for billions of years, providing Earth with the energy it needs for life.
The scientific term for nuclear energy is "nuclear power." This energy is produced through reactions in the atomic nucleus, specifically through processes like nuclear fission or fusion to generate heat that can be converted into electricity.

It can be used to generate power but it is very dangerous yet little nuclear energy can generate ALOT of power.
