To find the fuel cost per energy unit for different energy sources, there are several reliable sources you can refer to:

1. Government Energy Agencies: Many countries have government agencies dedicated to energy and natural resources. These agencies often provide detailed information on the cost of various energy sources, including fuel costs per unit of energy. Examples include the U.S. Energy Information Administration (EIA), the International Energy Agency (IEA), and the European Union's Energy Portal.

2. Utility Companies: Energy utility companies often publish information about their fuel costs. This information may be available on their websites or can be obtained by contacting their customer service departments. Utility companies typically provide data on the cost of various sources, such as natural gas, coal, oil, and renewables, as well as the specific costs per unit of energy.

3. Energy Market Reports: Industry reports and market analysis publications can provide valuable insights into fuel costs per energy unit. These reports are often prepared by research firms, energy consulting companies, or financial institutions. Examples include Bloomberg New Energy Finance, S&P Global Platts, and Wood Mackenzie.

4. Academic and Research Institutions: Universities and research institutions often conduct studies and publish reports related to energy costs, including fuel prices. These publications might be available through their websites or databases. Examples include the Massachusetts Institute of Technology Energy Initiative (MITEI) and the National Renewable Energy Laboratory (NREL) in the United States.

5. Industry Associations: Energy industry associations such as the American Petroleum Institute (API), the World Coal Association (WCA), and the International Renewable Energy Agency (IRENA) often release reports and data related to energy costs and fuel prices. These organizations represent different sectors within the energy industry, making their insights valuable.

By referring to one or more of these sources, you can find reliable information on fuel costs per energy unit for different energy sources without the need for individual calculations.
