Wow, I had no idea about this:
Raise your hand if you knew that streetlamps accounted for 38 percent of all energy used on lighting in the USA.
That’s amazing.
(Side note: I’ve been mysteriously absent from the blog (and responding to a few emails that are hanging in the back of my inbox) the last few weeks. More on that later, but for now, you’ll have to accept this).
Update: Wow, I forgot to link back to the source article from this with more information about it, and a possible solution. Bad Marius.
