I've lived in the Ithaca area with my wife for 2 years. We've been fixing a house near Jacksonville, but really have our sights set on building an earth-sheltered masonry home; stone/timber from the site, passive solar heating, masonry heater, solar hot water, photovoltaic electric (and maybe wind/micro-hydro, as the site presents itself), rainwater catchment, composting toilets, greenhouse/gardens,-- ya know, your usual list of sustainable stuff. Renewable energy systems are my area of expertise, having designed/ installed photovoltaic and micro-hydro systems as a business for people in the past. I currently do energy load analysis and site energy resource consultation for people. Basically, I study your power usage and recommend the most effective ways to improve efficiency, and study your site to determine amount of power that may be gained through photovoltaics/wind/water. I use a Solar Pathfinder tool to determine the optimum site and maximum percentage of solar energy that can be gathered. Based on this information, if you wish, I can generate some ballpark cost figures for various systems to cover likely scenarios at your site. I do not currently sell equipment, but have experience with many of the renewable energy equipment brands and companies, and several years of living with photovoltaic power systems. For this service, I trade Ithaca Hours or straight time of your suitable expertise or service. I look forward to working with all of you as we build our sustainable lives together.
