Gas countertop ranges are generally less energy-efficient than electric ones. Gas ranges convert about 30-40% of their energy into cooking heat, while electric ranges convert about 70-80%. This is because gas ranges lose a significant amount of energy through heat dissipation into the surrounding air. Electric ranges, particularly those with induction technology, are more efficient as they directly transfer energy to the cookware through electromagnetic fields, minimizing heat loss.
However, the overall cost-effectiveness and environmental impact depend on several factors. Gas is often cheaper than electricity, which can make gas ranges more cost-effective in terms of operating expenses. Additionally, the source of electricity plays a role; if the electricity is generated from renewable sources, electric ranges have a smaller carbon footprint compared to gas ranges, which rely on fossil fuels.
In terms of cooking performance, gas ranges offer precise temperature control and instant heat, which some cooks prefer. Electric ranges, especially induction, provide faster heating and are easier to clean due to their smooth surfaces.
Ultimately, the choice between gas and electric ranges depends on personal preferences, cooking habits, and local energy costs and sources.
