Sustainability and Impact Analysis
NREL's sustainability analysis looks at the environmental, life cycle, climate, and other impacts of geothermal energy technologies.
Sustainability analysis has three components: environmental effects, externalities, and economics and financing. Through our analysis, we review, analyze, and report the sustainability metrics for geothermal technologies, including subsurface technologies (e.g., hydrothermal, enhanced, and advanced geothermal systems) and surface technologies (e.g., flash and binary plants, direct heat applications, and geothermal heat pump systems).
- Systems modeling and analysis
- Hydrology and water use and consumptive use modeling and analysis
- Geospatial analysis for gathering, managing, and analyzing data
- Environmental analysis
- Techno-economic analysis
Our energy-water nexus analysis helps policymakers, researchers, and investors understand the relationship between the water used for energy production—including electricity and sources of fuel such as oil and natural gas—and the energy required to extract, purify, deliver, heat, and cool that water and treat and dispose of wastewater.
Life Cycle Assessment Harmonization
Our life cycle assessment harmonization reduces uncertainty around estimates for environmental impacts and provides lenders, utility executives, and lawmakers with information about greenhouse gas emissions from various sources of energy.
