The sentence "Those relying on wind power, however, were in better shape than most" implies that people relying on wind power were better off compared to others in the aftermath of the Texas power crisis. The evidence to support this statement is given in the preceding paragraph where the author explains that wind turbines continued to generate electricity during the winter storm, although at reduced capacity due to ice accumulation. This suggests that people with access to wind power may have had a more reliable source of electricity compared to those who relied on the power grid, which experienced widespread blackouts.
