Julie Williams, Seeds for the Sol by Amy Hunter on Vimeo.

Inspired by her Climate Reality training, Julie Williams created this innovative wealth-sharing program that provides zero interest loans to homeowners for solar installations. Using investments by “Sun Buddy’ donors who get paid back by tax credits and rebates; this is a community-based solution for ramping up clean energy solutions in Corvallis, OR. USA.
