2. Advantages and limitations of electrothermal energy

The main advantages for the development of electrothermal electricity are as follows.

• Variety of techniques (see table 1 )

  For each industrial process under consideration, the most suitable electrothermal process or combination of processes can be identified.

  By way of example, the table 2 shows how the various electrical technologies were used in industrial applications in France in 1996.

• Very high energy conversion efficiency

  Taking into account various efficiencies,...
