Strategy of Geothermal Energy Development as a Renewable Energy Source: A Review

The Untapped Potential of Geothermal Power

Geothermal energy, a renewable resource harnessed from the Earth’s natural heat, holds immense promise as a sustainable solution to the global energy crisis. As the world transitions away from fossil fuels, the strategic development of geothermal power presents a compelling opportunity to diversify the renewable energy portfolio and accelerate the shift towards a greener future.

Geothermal energy, unlike intermittent sources like solar and wind, offers the advantage of reliable, baseload power generation. By tapping into the Earth’s internal heat reservoirs, geothermal power plants can operate around the clock, providing a consistent and dependable supply of electricity. This stability is particularly valuable in stabilizing the grid and complementing the variable nature of other renewable energy sources.

The United States, with its vast geothermal resources primarily concentrated in the western states, has made significant strides in leveraging this renewable energy source. The Bureau of Land Management (BLM), which oversees the development of geothermal resources on public lands, has played a crucial role in this progress. In Fiscal Year 2018, BLM-managed lands accounted for over 40% of the nation’s total geothermal energy capacity, underscoring the immense potential that lies within America’s public lands.

Regulatory Frameworks and Geothermal Leasing

The legal and regulatory landscape surrounding geothermal energy development has evolved over time to better accommodate this burgeoning industry. The Geothermal Steam Act of 1970 was a pivotal milestone, defining geothermal resources as steam, hot water, and hot brines and authorizing the Secretary of the Interior to issue leases for their development and utilization on federal lands.

Subsequent amendments, such as the Energy Policy Act of 2005, have further refined the regulatory framework, including the establishment of revenue-sharing mechanisms. These changes have helped to incentivize and streamline the geothermal leasing process, making it more attractive for energy companies to invest in exploration and development activities.

The BLM’s role in managing the environmental impacts of geothermal operations, as mandated by the Federal Land Policy and Management Act and the National Environmental Policy Act (NEPA), is critical. The agency must ensure that proposed geothermal development does not compromise sensitive ecological features, such as Old Faithful in Yellowstone National Park, while also facilitating responsible and sustainable growth.

Geothermal Energy Hotspots on Public Lands

The vast majority of the United States’ geothermal potential is concentrated in the western states and Alaska, with the BLM managing over 240 million acres of public lands open to geothermal leasing, including 104 million acres of Forest Service-managed lands.

California, the nation’s leading producer of geothermal energy on BLM-managed lands, is home to the world-renowned Geysers, the largest geothermal field globally. This complex of power plants generates approximately 800 megawatts of electricity, providing hundreds of full-time jobs and substantial revenue streams to the state and local governments.

Beyond California, Nevada has experienced a notable expansion of geothermal exploration and development on public lands, generating over $50 million in bonus bids for the U.S. taxpayer between 2007 and 2018. The BLM currently administers 19 geothermal power plants with federal interest in Nevada, totaling over 600 megawatts of installed capacity, with an additional 400 megawatts in the planning or permitting stages.

Streamlining the Regulatory Landscape

One of the key challenges in accelerating geothermal energy development has been the administrative burden associated with the environmental review process under NEPA. Each geothermal project requires separate environmental assessments, both at the exploratory phase and during resource utilization, which can add significant time and cost to the development timeline.

To address this issue, the BLM, under Secretarial Order 3355, has implemented measures to streamline the NEPA review process for all energy development projects, including geothermal. Additionally, the Department of Energy’s GeoVision report has identified that improved regulatory timelines for the drilling of exploratory wells could significantly reduce the administrative costs of geothermal development on public lands, potentially spurring new investment and growth.

By exploring further opportunities to streamline NEPA reviews and permitting processes, the BLM aims to facilitate greater utilization of these important geothermal resources, ultimately diversifying the nation’s energy portfolio, reducing carbon emissions, and aligning with the administration’s policy of responsible domestic energy development.

Strategies for Optimizing Geothermal Energy Utilization

As the United States continues to harness the power of geothermal energy, a comprehensive review of the West Java Province in Indonesia provides valuable insights into strategic approaches for optimizing geothermal energy development.

Infrastructure Improvement as an Investment Facilitation Strategy

One key strategy identified is the improvement of infrastructure as a means to facilitate investment in geothermal energy projects. By ensuring the availability of reliable and efficient infrastructure, such as transportation networks and power transmission systems, the barriers to entry for geothermal developers can be reduced, thereby encouraging greater participation and investment in the sector.

Leveraging Costly Investments and Capital

Additionally, strategies to leverage costly investments and capital, such as the implementation of underground mining techniques in conservation forest areas, can help to minimize the environmental impact of geothermal development while still unlocking the resource’s potential. This innovative approach can prevent the degradation of sensitive ecosystems and address concerns regarding land use conflicts.

Improving Supervision and Sustainable Development

Enhancing the supervision and coordination of relevant institutions and stakeholders is another crucial strategy. By strengthening the oversight and collaboration among government agencies, industry players, and local communities, the development of geothermal energy can be better aligned with principles of environmental sustainability and equitable socioeconomic benefits.

Fostering Community Engagement and Job Creation

Lastly, the importance of socializing programs and providing job opportunities for local communities cannot be overstated. By engaging with and empowering the communities that host geothermal projects, the industry can foster a sense of ownership and support, ultimately contributing to the long-term viability and acceptance of geothermal energy development.

Conclusion: A Sustainable Energy Future

The strategic development of geothermal energy holds immense promise as a reliable, renewable, and baseload power source that can complement the growth of other clean energy technologies. By capitalizing on the vast geothermal resources found on public lands, streamlining the regulatory landscape, and adopting innovative strategies for optimization, the United States can accelerate its transition towards a more sustainable and diverse energy future.

As the world navigates the challenges of climate change and the evolving energy landscape, the strategic approach to geothermal energy development presented in this review offers a roadmap for unlocking the true potential of this underutilized renewable resource. By embracing the opportunities and addressing the unique challenges of geothermal energy, the United States can cement its position as a global leader in the quest for a cleaner, more resilient, and equitable energy system.
