The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

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;
  • wind;
  • solid waste;
  • the decomposition of organic wastes;
  • 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

3. A small system that uses water power by means of an impoundment that is not over 20 acres in surface area.
