Moreover, PHEVs can significantly reduce greenhouse gas emissions and air pollutants compared to conventional vehicles. Studies show that, when charged regularly and used primarily in electric mode, PHEVs can lower CO2 emissions by up to 50% or more, depending on the source of electricity. This reduction in emissions contributes to improved air quality, particularly in urban areas where traffic congestion is a significant issue. With governments and organizations around the world prioritizing efforts to combat climate change, PHEVs represent an important step toward achieving sustainable transportation goals.

Typically, galvanized iron sheets are available in various thicknesses measured in gauges. The most common standards range from 18 gauge (approximately 1.2 mm) to 26 gauge (approximately 0.5 mm). Thicker sheets, like 18 or 20 gauge, are commonly used in applications requiring structural strength, such as construction and industrial settings. In contrast, thinner sheets are often applied in manufacturing and household fixtures where weight and flexibility are crucial.
