Fossil fuel-based electricity consumption is an environmental hotspot in M1 and M2 fabrication. India depends mainly on coal and other fossil-fuel-based thermal power plants for electricity generation. A sensitivity analysis was performed by comparing the electricity used in India (Western Grid), the UK, Canada (Alberta), and the Indian state of Gujarat (solar photovoltaic energy). The electricity of the UK is mainly derived from natural gas, nuclear energy, and several renewable energy sources, with very little dependence on coal .
