Exempts sales of energy-saving products and services from sales and use tax.

This bill exempts the sales tax on specific energy-saving products and services when purchased by consumers or businesses. It covers items like LED light bulbs, insulation, window weather stripping, tankless water heaters, and furnace filters, which are defined as products or services primarily designed to reduce energy use in homes and buildings. The tax exemption applies to retail sales made after the bill takes effect, removing the sales tax burden on these items. This change directly benefits homeowners and businesses looking to install or buy energy-efficient upgrades.
