There's lot of talk of making homes "greener" through energy efficiency or distributed renewable energy. But what's the equipment that you need to do this?
This photo gallery will give you a glimpse of what's involved and test your knowledge along the way. The slideshow is both a collection of nifty images from the North East Sustainable Energy Green Building Conference, which took place last week in Boston, and an interactive quiz.
Each photo will have a question. Click to the next photo to get the answer and another question. Keep track of how many you get right. At the end, there will be a highly subjective "energy geek" rating system.
First question: What is this device from Energy Revolutions?
A. An industrial corkscrew to clear water mains
B. A vertical-axis wind turbine
Answer next page. (Don't worry, the questions get harder.)
