On April 11, 2025, the Colorado State Legislature introduced House Bill 1165, aimed at enhancing the regulation of geothermal resources and ensuring the protection of groundwater resources. The bill seeks to address concerns regarding the environmental impact of improperly constructed wells and geothermal systems, which can pose risks to public health and safety.

Key provisions of House Bill 1165 include amendments to existing statutes that govern the allocation and use of geothermal resources. Notably, the bill stipulates that the Colorado Commission and the State Engineer must coordinate on the issuance of operational and use permits, ensuring that the management of geothermal fluid and water is streamlined and effectively monitored. This coordination aims to clarify whether accounting for the use and reinjection of geothermal resources should be submitted to one or both regulatory bodies.

The bill also emphasizes the importance of proper construction, repair, and abandonment of wells and geothermal systems, highlighting scientific evidence that links poor practices to adverse effects on groundwater. This legislative declaration underscores the need for stringent oversight to safeguard Colorado's water resources.

Debate surrounding House Bill 1165 has centered on the balance between promoting geothermal energy development and protecting environmental resources. Proponents argue that the bill is essential for sustainable energy practices, while opponents express concerns about potential regulatory burdens on geothermal operations.

The implications of House Bill 1165 are significant, as it could pave the way for increased geothermal energy utilization in Colorado, aligning with broader goals of renewable energy expansion. However, the bill's success will depend on navigating the complexities of regulatory compliance and addressing stakeholder concerns.

As the legislative process unfolds, further discussions and potential amendments are anticipated, reflecting the ongoing dialogue about energy, environmental stewardship, and public health in Colorado.
