Design Principles

"Maximize renewable energy integration by storing surplus electrical energy as thermal energy for later use."

This approach directly addresses the challenge of integrating intermittent renewable energy sources like solar and wind. By storing excess electricity as heat, designers can create more resilient and environmentally friendly energy infrastructures, reducing reliance on fossil fuels and minimizing the carbon footprint of built environments.

What This Means for Your Design

Using special heaters (Power-to-Heat) and big underground storage tanks (Seasonal Thermal Energy Storage) can help us use more solar and wind power by storing the extra energy as heat for later, which is better for the environment.
