Policy Issue and Introduction
Renewable energy refers to energy generated from naturally replenished sources like sunlight, wind, water, plants, and geothermal heat. It includes established technologies such as hydropower, bioenergy, and geothermal energy as well as emerging sources like solar photovoltaics (PV), wind turbines, and ocean energy (IRENA, 2019). Renewables offer energy security as they utilize domestic resources, unlike importing fossil fuels. Solar, wind, hydro, and other renewables also produce negligible greenhouse gas emissions during operations, helping address climate change (IPCC, 2022). The Philippines has abundant renewable energy resources such as solar, geothermal, hydro, and biomass that can meet and even exceed domestic demand if fully tapped (Gulagi et al., 2021).
