Why We Need Space Energy
We face two interconnected energy crises — clean abundance and global transmission. Space-based solar power addresses both simultaneously.
TerraSpark argues that humanity faces two interconnected energy crises: a clean abundance crisis, where current renewables face limitations in scale, consistency, and land use; and a global transmission crisis, where the infrastructure to move energy to where it is needed most does not exist. Space-based solar power (SBSP) addresses both by collecting solar energy in orbit where the Sun shines 24/7 and transmitting it wirelessly to any point on Earth.
SBSP offers five times the efficiency of terrestrial solar without the need for overbuild or storage, minimal land use with five times more energy per square metre than ground-based solar farms, and built-in global transmission that eliminates the need for costly grid infrastructure. At scale, TerraSpark claims SBSP can deliver reliable power at competitive system-level costs per kilowatt-hour.
Falling launch costs, advances in robotics, RF-based wireless power transmission, and materials science have made SBSP economically viable for the first time. TerraSpark positions SBSP not as a replacement for terrestrial renewables but as a complement that solves problems other renewables cannot address.
