Renewable Energy and Energy Conservation Tax Act

Renewable Energy and Energy Conservation Tax Act - Allows an income tax credit for 30 percent of the expenditures not exceeding $750 which the taxpayer paid or incurred during the taxable year for the installation of insulation or energy-conserving components which improve heating plant efficiency in his principal residence. Limits the application of this credit to expenditures paid or incurred for installations made between 1976 and 1982 in pre-existing dwellings. Reduces the allowable credit, on a graduated scale, for individuals with adjusted gross incomes greater than $10,000.
