Science : No single or combination of alternative energy resources can replace fossil fuels
Preface. Even though this research was from 2002, it is still true today. There simply are no replacements for the fossil fuels that power our civilization. If only scientists could violate the laws of thermodynamics and physics.
Even if there were Something Else, we’re running out of time, energy, and mineral resources to replace fossil fuels despite having had all of human history and the last few centuries to find alternatives. Energy transitions take decades. It took 50 years for oil to capture 10% of global energy after it was first drilled in the 1860s, and 30 more years to provide 25% of all energy. It took 70 years for natural gas to go from 1% to 20% of global energy (Smil 2010).
The larger the scale of existing infrastructure, the longer fossil substitution will take. In 2019, wind and solar contributed just 1.3% of total world energy consumption (BP 2020).

None of the known alternate energy sources are technically ready to take the place of fossil fuels experts say in a new study.
The study by 18 scientists and engineers in university, government and private labs evaluated technologies that would make energy without burning oil, coal or natural gas and found that no single system or combination of systems could replace these fossil fuels.
Hoffert said a combination of renewable energy sources — such as wind and solar power generation, or electrical power beamed from orbiting solar satellites, and nuclear fusion power plants — “are theoretically capable of keeping our civilization going into the future, but the problem is that we haven’t taken the challenge seriously enough to do research in it. We are putting practically nothing into really, seriously studying the problem.”
