The International Energy Agency (IEA) is the global authority on worldwide fuel supplies, trends, and outlooks. They have the ear of the world’s governments and business, and they help set policy by conducting the research necessary to define global fuel inventories and costs. So when they release a first-of-its-kind report that pinpoints theworld’s most important fuel, it’s kind of a big deal.
Here’s a list of the fuels that will not wear the crown of “Most Important Fuel in the World”: oil, biodiesel, nuclear, wind, hydro, geothermal, solar, wave energy, biomass, hydrogen, ethanol, coal.
Wait, it’s not a renewable like wind or solar? And it’s not ‘clean coal’? Okay. The US is sitting on enough natural gas to power the world for a hundred years so that’s gotta be it, right? Nope. It’s not even natural gas, the USA’s game-changing energy trump card. In fact, the IEA says the most important fuel in the world isn’t a fuel at all.
The most important fuel in the world…is energy efficiency.
Here are the guts of the IEA’s report:
