Imagining a world devoid of fossil fuels reveals the drastic shift needed across all sectors of the global economy. While the U.S. has seen significant declines in coal and increases in renewable energy, the transition will take years. Fossil fuels remain a dominant energy source globally, but the cheaper cost of clean energy is facilitating this change. However, emissions targets set by the Paris Agreement are contingent on more than just reducing fossil fuel usage; the agricultural sector's impact on climate change through land use and food production must also be addressed.
Even as a thought experiment, it's almost unimaginable. Fossil energy is so ubiquitous, so useful, so entrenched. But radical change always seems unimaginable before it happens.
Fossil fuels are only two-thirds of the climate problem. Even if we quit them, we'll never meet emissions targets without addressing the other third: food production.
