Suppose there are 5 types of renewable energy sources and the analyst wants to select 3 for a pilot project. In how many ways can the analyst choose these sources if the order of selection does not matter?

In an era of rapid climate transition, the selection of renewable energy pilot projects shapes the future of clean power deployment across the United States. When policymakers and analysts evaluate combinations of renewable energy sources, the question of how many viable groupings exist becomes both technical and practical. With five distinct energy types available—such as solar, wind, geothermal, biomass, and hydro—the pursuit of optimal pilot configurations hinges on thoughtful
