Energy Revolutions
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.)
