The 2009-2010 Geothermal Heating and Cooling Systems State Regulatory Oversight Survey represents the most complete and accurate information for geothermal system regulation available anywhere. The report is designed to allow readers to easily compare state regulations as well as aggregate data on all responding states.

The report is divided into two major sections. The first section contains a quick graphical overview of which geothermal systems are regulated. The second portion shows aggregated data for all responding states and each state's individual answers.

This book is volume two in the multi-physics modeling book series. It provides an introduction to the scientific fundamentals of groundwater and geothermal systems.
In a simple and didactic manner the different water and energy problems existing in deformable porous rocks are explained as well as the corresponding theories and the mathematical and numerical tools that lead to modeling and solving them.
This approach provides a thorough understanding of the basic physical laws of fluid flow, in thermoporoelastic rocks, the partial differential equations representing these laws, and the principal numerical method that allow finding approximate solutions of the corresponding mathematical models. The book also details the form in which specific models can be generated and solved.

This book provides a basis for understanding the emerging technology of ground source heating and cooling.
It equips engineers, geologists, architects, planners, and regulators with the fundamental skills needed to implement technologies for space heating and cooling.
The book is geared toward understanding ground source heating and cooling from the ground side (the geological aspects) rather than solely the building aspects.
This second edition is thoroughly updated and expanded to cover new technical developments and now includes end-of-chapter study questions to test the reader's understanding.
