🧩 How These Challenges Are Connected
It’s important to understand that these challenges don’t exist in isolation — they’re interconnected. For example:
- Grid constraints drive up costs and slow deployment
- High costs make it harder to invest in reliability improvements
- Workforce shortages increase installation costs and reduce quality
- Poor reliability reduces public trust and slows EV adoption
- Slow EV adoption reduces the business case for charging infrastructure investment
This is why a holistic approach is so important. Solving one challenge in isolation often doesn’t work — you need to address multiple challenges simultaneously.
