It argues that dedicated land use for bioenergy—including crop-based biofuels and cellulosic energy crops—exacerbates a projected 70 percent crop calorie gap by 2050. The authors contend that bioenergy is an inefficient use of solar radiation compared to solar photovoltaics (PV), which can produce over 100 times more energy per hectare. Furthermore, the document identifies a systemic 'double counting' error in greenhouse gas accounting that erroneously treats biomass as carbon-free. It recommends phasing out subsidies and mandates for land-dedicated bioenergy while prioritizing 'additional' biomass sources such as municipal waste and specific residues.","ai_generated":true,"unit":"wri-001190#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Phasing out crop-based biofuels could significantly reduce the projected 2050 crop calorie gap from 70 percent to approximately 60 percent.
