Central heating systems are commonly run using various energy sources, with the most prevalent being:
1. **Natural Gas**: Many traditional heating systems use natural gas as the primary fuel.
2. **Electricity**: Electric heating systems, including electric boilers and heat pumps, are widely used as well.
3. **Oil**: Some central heating systems still utilize oil as a fuel source, especially in areas where natural gas is not available.
4. **Wood or Biomass**: In certain regions, wood or biomass fuels are used for heating.
Among the options you've listed, both **electrical energy** and **geothermal energy** can be used to run central heating systems, but typically, electrical energy is the more common choice.
Solar energy can also be used, primarily in the form of solar thermal panels for heating water, but it is less commonly employed as the sole source for central heating. Nuclear energy is generally not directly used for residential heating systems.
Therefore, the most common option from your list would be **electrical energy**.
