72.8% Of World’s Renewable Energy Is Made By Burning Wood & Dung—20x More Than Wind & Solar Energy, a National Economics Editorial.
Renewable energy advocates have claimed for decades that solar and wind power are the future—and the future is right around the corner. Some boldly state that the world could be powered by renewable energy sources as early as 2030, given the exponential growth of solar and wind electrical capacity. …
Not there yet — watch out for the hype and the subsidies:
Despite thirty years of government subsidies and hundreds of billions in direct investments in green technologies, wind power still meets just 0.46% of the earth’s energy demands. … Wind power is useless, and will remain useless due to limited potential efficiency gains (restricted by the Betz limit), and land space requirements—we’d need to cover an area the size of the British Isles with wind turbines just to meet our annual growth in energy consumption. There’s simply not enough land. Never mind the problem of intermittentcy, and the hidden systemic risks it entails.
According to the International Energy Agency’s 2016 Key Renewables Trends Report, wind, solar, and tidal energy combined met just 0.81% of earth’s aggregated energy demands. And yet we’re constantly told that renewable energy makes up a much larger percentage than that. Why the disconnect?
Because green energy advocates mislead the public by either talking about (i) electrical energy or (ii) implying that “renewable energy” means solar and wind energy. …
Electrical energy only represents one-fifth of global energy consumption. The vast majority is consumed as fuel for transportation, heating, and cooking. …
While 13.6% of world energy comes from renewable sources, the vast majority — 72.8% — is just people in developing countries burning wood, charcoal, and dung for energy. … Feces is a more important energy source than wind power.
Photovoltaic cells require a staggering variety of rare earth minerals to build, one of the most important of which is silver. Given current technology (and assuming 20% efficiency), we’d need to cover an area the size of Spain in solar panels to generate enough electricity to meet our global electricity demands by 2030. … Even if we wanted to build that many solar panels, we couldn’t do it—there’s simply not enough silver in the world.
The only current technology we have that can provide enough electricity without emitting carbon dioxide is nuclear.
