demo: see this app in action at http://panels.pwipw.com This sustainable energy calculator was a collaboration between professor of Environmental Studies at Knox College, and Max Galloway, a former CS student at that institution. There are five parts, leading from considering your energy usage, to the benefits of solar panels and wind turbines. Each part is composed of two pages, the questions and the results. If the user input is valid (is numbers) then clicking "Calculate!" will bring the browser to the result page. The result page is mostly static html, with a few values filled in dynamically by a javascript file. The application is entirely client side, using html, css, and jQuery/javascript. jQuery Mobile is responsible for the application's look & feel, as well as ajax page transitions.
