Towards a Just and Sustainable Solar Energy Industry - A Silicon Valley Toxics Coalition White Paper, January 14, 2009.
Every hour, enough solar energy reaches the Earth to meet human energy needs for an entire year. Solar photovoltaic (PV) technology is widely seen as a “win-win” solution that can harness this “free energy” to address global warming, reduce U.S. dependence on energy imports, create “green jobs,” and help revitalize the U.S. economy.
Solar energy will play an essential role in meeting these challenges, but as the solar PV sector expands, little attention is being paid to the potential environmental and health costs of that rapid expansion. The most widely used solar PV panels are based on materials and processes from the microelectronics industry and have the potential to create a huge new wave of electronic waste (e-waste) at the end of their useful lives, which is estimated to be 20 to 25 years. New solar PV technologies are increasing cell efficiency and lowering costs, but many of these use extremely toxic materials or materials with unknown health and environmental risks (including new nanomaterials and processes).
With the solar PV sector still emerging, we have a limited window of opportunity to ensure that this extremely important industry is truly “clean and green,” from its supply chains through product manufacturing, use, and end-of-life disposal. The solar industry has taken a leadership role in addressing the world’s pressing energy and environmental challenges and will serve as a model for how other innovative “green” industries address the lifecycle impacts of their products.
In this white paper, the Silicon Valley Toxics Coalition (SVTC) provides an overview of the health and safety issues faced by the solar PV industry, including the toxic materials used in manufacturing and the potential end-of-life disposal hazards of solar PV products. The report also lays out recommendations to immediately address these problems to build a safe, sustainable, and just solar energy industry. These recommendations include:
- Reduce and eventually eliminate the use of toxic materials and develop environmentally sustainable practices.
- Ensure that solar PV manufacturers are responsible for the lifecycle impacts of their products through Extended Producer Responsibility (EPR).
- Ensure proper testing of new and emerging materials and processes based on a precautionary approach.
- Expand recycling technology and design products for easy recycling.
- Promote high-quality “green jobs” that protect worker health and safety and provide a living wage throughout the global PV industry, including supply chains and end-of-life recycling.
- Protect community health and safety throughout the global PV industry, including supply chains and recycling.
