B. The world could 21 fossil fuels within a decade, according to a new study. Writing in the journal Energy
Research & Social Science, Benjamin Sovacool, Director of the Sussex Energy Group at the University of Sussex, says the
world could wean itself off the polluting fuels quickly, 22 a “collaborative, interdisciplinary, multi-scalar effort.”
“Moving to a new, cleaner energy system would require significant shifts in technology, political regulations, tariffs
and pricing regimes, and the behavior of users and adopters,” he said. “Left to evolve by itself—as it has largely been in the
past—this can indeed take many decades. A lot of stars have to align all at once.” He added that the past may offer some
clues about 23 to transition from fossil fuels to cleaner, sustainable forms of energy. For example, for Europe to move from wood to coal took between 96 and 160 years, but electricity only took 47 to
69 years to be mainstream. Transitioning to cleaner energies could 24 by several factors, he said, citing “the
scarcity of resources, the threat of climate change and vastly improved technological learning and innovation.”
In the study, some of the quicker transitions are listed as potential road maps. For example, in Ontario, Canada, coal
was replaced from 2003 to 2014. In Indonesia, two-thirds of the population shifted from kerosene stoves to LPG stoves in
just three years. All of these, Sovacool says, were done with “strong government intervention 25 shifts in
consumer behavior.”
“The mainstream view of energy transitions as long, protracted affairs, often taking decades or centuries to occur, is
not always supported by the evidence,” he said.
