In order to be seriously considered as an alternative in any project, an energy source must be easily characterized in terms of cost, both capital and unit energy cost. Historically, this has been a difficult hurdle for geothermal energy. Its costs vary with the depth and character of the resource, number of production and injection wells, and a host of other parameters. As a result, even in cases where developers are interested in using the geothermal, identifying its costs has been a cumbersome process. To address this problem, the Geo-Heat Center has developed a spreadsheet which allows potential users to quickly evaluate the capital cost and unit energy cost of accessing a geothermal resource
