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. Click on the "What is the WEL?" link (above) to learn more, or explore the map below to see what other WEL users are doing globally.

Notice! There will be several periods in the coming months when the WELserver office will be closed, and no orders will be processed. Fear-not, WELserver.com will continue to function just fine, but there will be no one on-site to ship new orders. Any orders place during these periods will be processed in the order they were received once we return to the office.
Thanks for your patience during these periods.

The closed periods are as follows: May 7-31 and June 22-26
