Green or not? Environmental challenges from photovoltaic technology

Area of Science:

• Environmental Science
• Renewable Energy Technology
• Sustainability Studies

Background:

• Increasing global energy demands and the need for low-carbon sources are driving the expansion of photovoltaic (PV) solar energy facilities worldwide.
• PV solar energy presents a cleaner alternative to fossil fuels, offering significantly reduced pollutants and greenhouse gas (GHG) emissions.

Purpose of the Study:

• To review the environmental benefits of implementing PV technologies.
• To highlight the potential adverse environmental impacts associated with PV solar technology.
• To propose recommendations for enhancing the sustainability of PV technologies.

Main Methods:

• Comprehensive literature review of existing studies on photovoltaic solar energy.
• Analysis of environmental impacts, including biodiversity, habitat, climate, resource consumption, and end-of-life panel disposal.
• Synthesis of findings to identify areas for sustainability improvement.

Main Results:

• PV solar energy significantly reduces greenhouse gas emissions compared to traditional fossil-based power systems.
• Key environmental concerns include biodiversity and habitat loss, climatic effects, resource depletion, and the disposal of end-of-life PV panels.

Conclusions:

• While PV solar energy is crucial for a low-carbon future, its environmental footprint must be carefully managed.
• Implementing proposed strategies can improve the overall sustainability of PV technologies.
• Further research and policy development are needed to address the environmental challenges of widespread PV adoption.
