For , let's uncover: how clean is solar energy in Washington?
Solar energy is both renewable (source is naturally replenished) and clean (the total environmental impact is low). Here's how solar stacks up in the context of Western Washington's energy grid:
💡 Operational emissions: Solar produces zero emissions while actively generating electricity, providing clean energy from your rooftop for decades.
🏭 Lifecycle emissions: Solar does produce carbon emissions during manufacturing, but typically pays back its carbon debt within 1-4 years of installation.
♻️ Solar panel recycling: Solar panels are 90% recyclable. When homeowners are ready to upgrade their system, Solterra Solar will buy back their panels and recycle them, keeping them out of landfills and reducing the need for mining.
🌊 Solar vs. Hydropower: Washington's grid is 60% hydropower, making it one of the cleanest in the nation. However, hydro doesn’t offer homeowners energy savings, harms local river ecosystems, and is vulnerable to drought. We need both to transition confidently to a 100% clean energy future.
