The Spacefaring Institute LLC released Analysis of US 2100 Energy Needs and Sustainable Energy Sources. This analysis provides a quantitative assessment of US energy needs and what terrestrial and space-based sustainable energy sources will be able to practically replace fossil fuels and provide for the energy needs of a growing US population.

Abstract

Environmental and energy security threats will bring an end to the general use of fossil fuels in the United States this century. To replace fossil fuels, the United States will need to build an immense sustainable energy capability. Nuclear fission energy, wind energy, and ground solar energy are the three primary terrestrial alternatives while space solar power is the primary space-based sustainable energy alternative. None of the three terrestrial energy alternatives provide a practical replacement for fossil fuels. Space-based sustainable energy, including space solar power, provides a practical alternative. US immigration policy will substantially influence the life of the remaining US fossil fuel endowment and the cost of building the replacement energy sources.

Key words: United States, fossil fuels, 2100, CO2, carbon dioxide, nuclear energy, nuclear power, solar energy, wind energy, space solar power, immigration, energy security threat, environmental security threat, hydrogen, electrolysis, immigration policy, zero net immigration
