The energy efficient home improvement credit can only be used to reduce income tax due. If you have any income tax due then the credit will be applied to reduce it. If you don't then the credit will be rolled into future years.
Keep in mind that the credit can't be used to reduce self-employment tax. If you have any self-employment tax on your return then that will be paid as a separate bill from the energy efficient credit.
