Simply put, the WEL (or Web Energy Logger) is a cost-effective way to map the energy flows in your home or office. It can help verify the performance of a solar thermal system, calculate the efficiency of a geothermal installation, or even prove that your home really is "Net Zero".

Not only does the WEL give you a window into your own energy environment, but you can be part of a bigger green community and share your live system-snapshot and trend-charts on the WEB in real-time.
