A lot can happen over the course of a year, so we got to wondering: what was on TreeHugger's radar one year ago today? We hadn't heard of the Tesla, hadn't seen An Inconvenient Truth (or any Convenient Truths videos, for that matter) or shown our green ways to Martha Stewart or Oprah Winfrey.
Here's a quick peek at where the green world has been; might it tell us where it's headed?

1) SUV sales were taking a nosedive as hybrid sales were on the rise.
2) The K-1 Attack Hybrid sports car was built by high-schoolers, getting big-time press and sending a message to the major US auto manufacturers.
3) Corporate Knights magazine was showing us that they're devoted to working with business to create a "responsible corporate culture [that] can foster a more livable world for all."
4) The National Assembly of Wales' new green building, awarded the Building Research Establishment's (BRE) highest award for sustainable building construction, opened its doors for the first time.
5) In a tale of two cities, the town of Woking and village of Ashton in the UK were making big strides in alternative energy and sustainability.
