Science Wednesday: Year of Science – Do you know what energy resource you get your electricity from? Have you looked into switching to a "green" alternative?

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 April is Energy Resources.
