False Energies
Many alternative energy sources to fossil fuels have been proposed along the way.
These include algae, saltwater, landfill gas, cold fusion, biodiesel, ethanol, ocean waves, and hydrogen. All these have failed. Another proposed alternative, synthetic fuels, also failed despite being supported by President Jimmy Carter and Congress with close to $1 billion in funding.
Nuclear energy has shown commercial promise as an alternative but has largely been shut down by governments even though the process emits no CO2. Today the darling of the anti-fossil fuel crowd is wind and solar power, along with the batteries needed to store their intermittent and often unneeded generation of electricity for those times when the electricity is needed but wind and/or solar are not generating.
The hallmark of renewable energy sources in the ancient world—wind-, solar-, and hydro-power—was that they were dependent on the weather. They were all humankind had, along with animal power, for several millennia because the capital and technology needed to build the infrastructure to support fossil fuels were insufficient. It stayed that way until the 1800s, when wealth had expanded throughout the Western world to the point where coal, oil, and natural gas became economically viable.
