An inter-agency examine has discovered that federal lands within the contiguous United States may additional assist tons of extra gigawatts of renewable power (RE) era even when assuming restricted siting.
The examine by the Division of Power’s (DOE) Nationwide Renewable Power Laboratory (NREL), performed in cooperation with the agriculture, protection and inside departments, discovered there may be technical potential for five,750 gigawatts (GW) of utility photovoltaic (UPV) installations on 44 million acres of developable federal land throughout the contiguous U.S. The time period refers back to the decrease 48 states and the District of Columbia and excludes Alaska, Hawaii and U.S. territories.
For onshore wind, the technical potential — the utmost quantity of accessible useful resource primarily based on the quantity of federal land administered, suitability of the land for RE growth, and the power useful resource availability — is 875 GW on 43 million acres.

In the meantime the technical potential for hydrothermal is 130 GW on 12 million acres whereas that for enhanced geothermal is 975 GW on 27 million acres.
The Bureau of Land Administration (BLM) has the best technical potential of all federal land directors, adopted by the Forest Service and the Protection Division.
“DOE, FWS [Fish and Wildlife Service], and different federal land directors have comparatively modest RE technical potential”, said the report revealed on NREL’s web site.
“When modeling a limited-siting case, we estimate the technical potential on federal lands to say no by 70 % (to 1,750 GW) for UPV and by 96 % (to 70 GW) for wind, in comparison with the reference siting case”, the report stated.
Out of seven eventualities introduced within the report, the three central eventualities estimate 51–84 GW of photo voltaic, wind and geothermal capability are deployed onshore the contiguous U.S. by 2035, when the nation ought to have achieved one hundred pc clear energy as focused. The eventualities are primarily based on varied components together with know-how prices, efficiency assumptions, siting constraints and transmission interconnectedness.
“That stage of deployment by 2035, which may entail authorizing such tasks by round 2030, is sufficient to present as much as about 10 % of the dependable, renewable power wanted to succeed in net-zero emissions within the electrical energy sector”, the DOE stated in a web-based assertion.
The Inside Division has already permitted over 30 GW of fresh power tasks on federal lands, surpassing its congressionally licensed aim of 25 GW aim and forward of the 2025 goal date, the DOE stated. The permitted capability is sufficient to energy greater than 15 million houses, it stated.
The mixed capability of UPV, wind and geothermal ranges from 26 GW within the lowest estimate to 270 GW in probably the most optimistic deployment projection.
In most eventualities, lower than two million acres can be developed for renewable power by 2035, of which lower than 815,000 acres can be disturbed.
“For context, throughout fiscal 12 months 2023, 20.5 million acres of federal lands have been underneath lease for oil and gasoline growth, of which about 12.3 million acres have been actively used for manufacturing”, the report stated.
NREL used a geospatial mannequin to calculate the technical potential for RE sources. To assist make sure the mannequin follows reasonable assumptions, NREL sought experience from the BLM, the FWS, the Forest Service, the Protection Division and the DOE.
“The participation of the companion federal businesses is required for this examine given their experience on suitability for RE growth on lands administered by these businesses, in addition to their function in reviewing tasks on lands managed by different businesses, and their experience on different useful resource or land use concerns which may preclude or foster RE growth”, the report defined.
After figuring out the technical potential, NREL used a energy sector mannequin to establish what power applied sciences to construct and the place throughout the seven eventualities.
Power Secretary Jennifer M. Granholm stated, “DOE is a data-driven company and the info reveals that the nation’s rising power demand could be met with cleaner, cheaper, extra resilient energy”.
