Introduction to the economical and ecological advantages of using thermoelectric generators

Using waste heat of temperatures below 100° C is economically viable only to a certain extent. Waste heat from industrial plants may be used to heat rooms on the plant's premises or a nearby residential area.

Thermoelectric generators offer a modern, efficient and economically viable alternative. They convert heat flows directly (without requiring a steam generation process, for example) into electrical energy, the energy form of the highest quality by far. To this end, the generator employs maintenance-free and durable semiconductor components.

In contrast to other forms of renewable energy such as wind or solar energy, the “fuel” necessary to operate a thermoelectric generator, waste heat, is in many applications available around the clock. Many plants of the process industries are in operation 24 hours a day, that is up to 8,000 hours a year. To put this number into perspective: In Germany, the sun shines only about 2,000 hours a year.

For these and many other reasons, thermoelectric generators are a new, intriguing and sustainable option to choose to meet the world's energy demand.
