Why 100% renewables? Biofuel is renewable but also emits lots of carbon and air pollution. Nuclear is not considered renewable but is low carbon and clean air.

Why 100% renewables? Biofuel is renewable but also emits lots of carbon and air pollution. Nuclear is not considered renewable but is low carbon and clean air. Seems like the the term allows undue wiggle room. Might want to require that it be generated with energy that emits less than 50 gCO2-eq/kWh on a lifecycle basis or something more specific.
