This chapter examines the link between energy and the environment, presenting depth to the obvious environmental benefits of renewable energy, in addition to other externalities such as energy security. While always fraught with assumptions, using literature and his own calculations, he gives ranges for the externality costs of coal-based power, which then allows a more sustainable view of the price of renewable power. For coal based power, the mainstay of power in India today, these costs can be in the same order as the nominal costs of today. This is not to say there are no externalities to renewables, not only land use but also even carbon (especially during construction of solar panels), but these need to be in perspective. One of the takeaways to try and internalize the externalities (e.g., through pollution taxes) is the need for better numbers on the lifecycle costs, which start with fuel extraction (mining), and extend to power plant chimney stack emissions, as well as water usage.
