United Airlines just became the first airline in history to operate a passenger flight using 100% sustainable aviation fuel
United Airlines has become a global leader in reducing the aviation industry's carbon footprint. In 2016, the carrier became the world's first airline to continuously use sustainable aviation fuel in its regular operation, mixing it with conventional jet fuel in the same engine.

Currently SAF is "up to 8 times the cost of conventional Jet-A".
But it "feels good to say you use it"!
Corn ethanol has been criticized for years as environmentally unfriendly to the environment. Using foodstuffs as alternative fuels has always been problematic.
From Pepperdine University: "Unfortunately, environmentalists contend that corn-based ethanol is the least environmentally friendly of the main alternative fuels. Corn is an energy intense crop and requires a great deal of either natural gas or fossil fuels to break it down into ethanol."
This may be just as doubtful as "clean" electric cars - just don't ask about power plant emissions or the impacts on the electric grid.

Yep, this is the one subject that both my liberal uncle and I can find agreement on, but for different reasons. He hates it for the environmental side of things, and I hate it because I see how much it costs consumers in repair work due to ethanol's propensity for grabbing humidity from anywhere and everywhere, then settling out to the bottom of the tank and carburetor to corrode metal to oblivion, & plug up both fuel and air passageways. Not to mention how it leans out the fuel mixture, and hardens hoses to a brick in short order. ANYTHING would be a welcome substitute.
It does make me a PILE of money every year, so I can't really complain ... but when something ain't right, it ain't right!

A pilot friend of mine flew for a biofuel company. When I asked why they were looking at a plant near a coal mine and not near farmland, he said “they use so much energy to process corn it’s just as easy to put it there”.
It's well known that new renewable plants are being put near existing coal plants sometimes because those places already have a lot of the required infrastructure, including grid capacity to send the power out. The idea is to eventually shut down the coal plants and "switch over" effectively to the new power source. Assuming that you meant coal power plant and not just coal mine. That being said, I'm a big fan of coal, I think we should use what we have and focus efforts on smoke stack carbon and pollutant capturing tech.
Oh, throw in the BS subsidies of OTHER PEOPLES' MONEY to pay farmers to grow corn for that bullshit.
The Democraps constantly claim ordinary business expenses are a subsidy. The corn crap IS a subsidy. And congress critters on both sides are pushing it for the sake of votes.
Ted Cruz is the ONLY one I've heard preach against tax subsidies for farmers. "Let the free market work." And, when government keeps out of it, the free market does indeed work.
