I am interested in using alternative energy in my house. I live in NY about 10miles west of Manhattan in a 2-story attached house. I have been interested in solar , wind and geo-thermal , but I don’t know which will work best in my area.

We currently use an oil based boiler/furnace for steam heat and hot water (6 cast-iron radiators – only 5 are in use) (2 showers + 3 sinks).

I need some help in finding the best system for our house.
Provide enough renewable electric energy
Heat for the winter months w/ cooling during summer
Hot water for the shower and sinks

Thank you
