Legal Definitions - renewable electricity standard

A renewable electricity standard (RES) is a law that mandates a specific percentage of a state or country's electricity to be produced from renewable energy sources. Renewable energy sources include solar, wind, geothermal, hydroelectric, and biomass.

For example, California has set a goal of generating 100% of its electricity from renewable sources by 2045. This means that all the electricity used in California will come from renewable energy sources like solar, wind, and hydroelectric power.

Another example is the Renewable Portfolio Standard (RPS) in the United States, which requires each state to generate a certain percentage of its electricity from renewable sources. The RPS varies by state, with some states having a higher percentage requirement than others.

These examples illustrate how a renewable electricity standard works by setting a target for the amount of electricity that must come from renewable sources. This helps to reduce greenhouse gas emissions and promote the use of clean energy sources.
