The document is an op-ed arguing against a proposed renewable portfolio standard (RPS) that would require a certain percentage of electricity to come from renewable sources like wind and solar. It summarizes that an RPS would functionally operate like carbon emissions caps by restricting access to more economical fossil fuels and inflating electricity costs. It also argues that an RPS would strengthen lobbying from the renewable industry and likely grow over time into higher requirements. The op-ed urges Republicans in the Senate to reject compromises like the proposed RPS in order to avoid distorting energy markets and increasing costs for consumers.
