As power slowly comes back on in the lone star state due to a nationwide winter storm leaving millions without power, the massive blackouts are mainly caused by climate change, according to a solar energy expert.

Shannon Fulton with Straight Up Solar said while artic temperatures blast parts of the Midwest and Texas, state grids cannot handle the freezing temperatures, and that's leaving millions without power in its path.

Fulton says although frozen, wind turbines are still working up to 80% capacity and are the answer for the future.
