In 2016, the Lawrence Berkeley Laboratory and the National Renewable Energy Laboratory assessed the costs, benefits and impacts of RPSs across all the states that had them (based on 2013 data, the latest then available). They defined costs as those shouldered by electricity suppliers of complying with the RPSs and benefits as net environmental benefits across all of society. The benefits are: - Reductions of greenhouse gas emissions and climate change damage - Human health and environmental benefits of reducing emissions of air pollutants - Water use reduction Download the case study to learn more.
