the best free weather data source on the web.
Welcome to the weather data depot! Weather is free, so data about weather should be free, right? So, here it is - free degree day and energy usage reports. Use them to track average daily temperature; compare weather between two different years; record cooling and heating degree days; predict how much energy you’ll use due to the upcoming weather. There’s no limit to what this information can do for you. Thank you for visiting the depot.
Come back often.

Energy Usage vs. Degree Days
-Does your weather affect your energy consumption?
This advanced feature is under construction. First, you will enter energy bills for the past twelve months as well as brief information about your home or facility (year built, type of heating and cooling systems, approximate floor area, etc.). EnergyCAP will then statistically correlate your energy usage with the matching degree days in each billing period, determine if there is a valid correlation between usage and weather, and create an equation (a mathematical model) that indicates the daily base load (the non-weather portion) and the weather factor (the usage per degree day). This functionality is available today within EnergyCAP software; the estimated completion date for the Web-based tool is 2008.
