What is the primary benefit of renewable portfolio standards (RPS)?

The primary benefit of renewable portfolio standards (RPS) lies in their ability to mandate a specific percentage of renewable energy sources that must be included in the energy supply mix. This regulation is designed to encourage the production and consumption of renewable energy, thus promoting cleaner energy sources such as wind, solar, and hydroelectric power.

By establishing these requirements, RPS create a market demand for renewable energy, which can drive innovation, reduce greenhouse gas emissions, and diversify energy sources. This contributes to a more sustainable and resilient energy grid, as integrating a higher percentage of renewables can lead to a reduction in reliance on fossil fuels. Over time, this shift can significantly influence overall energy policy and help in the transition to a low-carbon economy.

The other options do not address the main focus of RPS. While nuclear energy is a viable energy source and can play a role in reducing carbon emissions, it is not the primary intention of RPS to promote it. Reducing energy consumption is a broader goal that may indirectly relate to RPS goals, but it is not the direct purpose of these standards. Finally, RPS do not limit consumer choices; instead, they encourage the integration of more renewable options into the energy market, thereby enhancing consumer choices regarding energy sources
