Residential taxpayers who install an energy system using a recognized non-fossil form of energy on their home after December 31, 2001 are eligible for a tax credit equal to the amount of the cost of the system and installation of the system, not to exceed $500. This cap is for individual taxpayers, so married taxpayers filing jointly can get a tax credit of up to $1,000 per household. The tax credit may be carried over for the following four taxable years.

Recognized non-fossil forms of energy generation means:

1. A system that captures energy or converts energy sources into usable sources, including electricity, by using:

  • solar energy, including passive solar systems;

  • geothermal;
  • fuel cells that do not require hydrocarbon fuel; or
  • an alternative energy system;
2. A system that produces electric power from biomass or solid wood wastes; or
