Are you an owner of an electric vehicle, biodiesel-powered or Natural Gas-powered car? Or are you in the market for one and are on the fence about where you'll be able to fill up or plug in?

Thanks to the company, Iconosys.com, there are apps on your mobile device that can help you out. They're releasing four new "Alternative Fuels" directory apps --  "Where to get NGV" "Where to get Biodiesel" "Alternative Energy Fueling Directory" and "My Plug-in Directory (for electric cars)." The apps can be accessed throughout the United States.

They're first being released on Android-powered mobile devices and are coming soon to other systems like Apple's i devices.
