Create Space-Based Energy Systems

Discover how space-based solar energy systems could solve global energy challenges by harvesting unlimited solar power from orbit. Join the journey to a sustainable, carbon-free future driven by advanced technology.

SUMMARY

Problem: Growing energy demand, climate change, and reliance on fossil fuels threaten global stability.
Solution: Space-based solar energy systems (SBES) harvest sunlight in orbit, providing a continuous, clean, and renewable energy supply to Earth.
Impact: This innovation can provide a stable, scalable, and sustainable energy source while reducing greenhouse gas emissions.
Stakeholders: Governments, space agencies, private sector innovators, energy companies, and global citizens.

CONTEXT

Earth’s increasing energy needs, coupled with climate change, require transformative energy solutions. Solar power, though abundant, faces challenges such as weather variability and night-time interruptions. Placing solar collectors in space, where sunlight is constant, could eliminate these issues, offering an unparalleled opportunity to meet global energy demands sustainably.

Urgency: With a projected 50% increase in energy demand by 2050 and worsening climate impacts, immediate action is critical.
