(D) assess and integrate, to the extent practicable, any technology, including electric, hydrogen, nuclear, biofuels, and any other sustainable fuel technology or renewable energy technology, that may reduce operational energy demand in the near term or long term;

(E) assess and consider any infrastructure investment of allied and partner countries that may affect operational energy availability in the event of a conflict with a near-peer adversary; and

(F) assess and integrate, to the extent practicable—

(i) any technology that increases sustainability and lowers emissions; and
