Science Wednesday: Year of Science Question of the Month – What technologies do you use to be more green? What one technology do you hope is available soon?

Each week we write about the science behind environmental protection. Previous Science Wednesdays. 

For each month in 2009, the Year of Science—we will pose a question related to science. Please let us know your thoughts as comments, and feel free to respond to earlier comments, or post new ideas.

The Year of Science theme for March is Physics and Technology.

What technologies do you use to be more green? What one technology do you hope is available soon?
