Energy In Brief

What is a cap-and-trade program and how does it work?

A cap-and-trade program is designed to reduce emissions of a pollutant by placing a limit (or cap) on the total amount of emissions. The cap is implemented through a system of allowances that can be traded to minimize costs to affected sources. Cap-and-trade programs for greenhouse gas emissions would increase the costs of using fossil fuels.


What are renewable portfolio standards (RPS) and how do they affect generation of electricity from renewable sources?

Renewable portfolio standards are policies designed to increase electricity generation from renewable resources, including wind, solar, geothermal, and biomass. Many States have their own renewable portfolio standards, although currently there is no program at the National level. States with renewable portfolio programs have seen an increase in the amount of electricity generated from renewable fuels.
