Renewable energy sources are significantly impacting architectural design by encouraging more sustainable and self-sufficient buildings. Architects are increasingly integrating solar panels, wind turbines, and other renewable technologies into their designs. 

This shift is leading to buildings that can generate their own energy, reducing reliance on fossil fuels and lowering carbon footprints. The use of renewable energy also influences the building's design and orientation; for example, buildings might be designed to maximize solar gain or positioned to take advantage of prevailing winds. Beyond individual buildings, renewable energy is influencing urban planning, with cities looking to create more sustainable, energy-efficient communities. 

This move towards renewables is not just about technology but a broader shift in how we think about and design our built environment.
