How is helium which is produced by the conversion of hydrogen into energy related to the solar core?
Helium that is produced by the conversion of hydrogen into energy is related to the solar core in the sense that the conversion process produces energy captured in the core.
Hydrogen is not a renewable fuel. It is a secondary energy source (or an energy carrier) that could be produced using another primary energy source. Hydrogen could be produced using either renewable primary energy source (e.g. solar energy), nuclear energy, or by using fossil fuel (e.g. natural gas)
