For companies, new requirements are constantly emerging. Novel technologies create new market segments while others disappear. Assessing this and aligning with it presents a challenge that few succeed in. Often, a trend is only recognized when it is too late and the competition has already taken the lead. Alternatively, developments may be ignored, and there is no response to market adjustments, leading to a struggle for ever-narrower margins in existing areas of activity until all reserves are exhausted. The introduction of geothermal probes for harnessing geothermal energy is a new trend in the construction industry. Demonstrating how to benefit from this has become the objective of the book. The introductory chapter describes how heating costs for consumers have been rising for years. Since it cannot be assumed that gas and oil prices will decrease, the question remains how heating costs will be managed in the future.
