In 2016, almost every country in the world signed and ratified the Paris Agreement, the most significant concerted action toward mitigating climate change to date. While noteworthy and ambitious, the Paris Agreement’s goal of keeping global warming below the scientific consensus threshold of two degrees Celsius continues to become less realistic absent more substantial actions to achieve a low-carbon energy infrastructure. One strategy debated in recent years involves using natural gas as a “bridge fuel” to a low-carbon energy economy. The main argument in its favor is that it is a cleaner, conventional, and cost-effective substitute to coal. However, recent studies have concluded that this strategy might actually “exacerbate the climate change problem” because of methane leakage associated with natural gas and by “delaying deployment of renewable energy technologies.” Still, proponents of the “bridge fuel” strategy argue that natural gas is needed until we solve the two major problems of renewables: intermittency and cost. These “bridge fuel” proponents claim that dispatchable sources like natural gas, coal, nuclear, and hydro are necessary to ensure grid reliability because they can be stored and switched on at a moment’s notice whenever required. The inherent intermittent quality of renewables arguably makes those sources less reliable and not as dispatchable compared to supposed “baseload” sources. The traditional concept of baseload sources is that they “operate continuously to meet the minimum level of power demand 24/7,” with nuclear and coal power used as prime examples. . . .
