- Landscapes, wildlife and water resources must be protected
- BLM required to satisfy both requirement

18. Look at Water Mitigation
• Solar thermal technology requires a considerable
amount of water for cooling
• Water is scarce, but companies
can reduce their needs
– Use waste or recharge water
instead of groundwater
– Encourage wet cooling where it
is sustainable
– Retire agricultural wells to
offset water used to cool
– Use non‐ or low‐water technology for on‐site hygiene
– Trade energy for water (NAWAPA)
– Develop near CAP and purchase from water owners
