Electrical ranges should be required to vent, too. The act of heating food to cooking temperatures already causes indoor air pollution, so ventilation should be required everywhere (not that would ever happen, especially retroactively to homes already built, but I can dream).
I agree that buying fuel at those prices aren’t economically feasible. But, if we end up in a world where we have far more generation capacity than there is normal demand, that excess capacity might prove to be useful for energy-intensive chemical production, including making fuel.
Sustainable aviation fuel doesn’t need to come from biomass feedstocks (even if those are by far the most popular). There are pathways for purely synthetic hydrocarbon production, but most sustainable fuel comes from organic sources (crops, organic waste, or fossil fuel sources). Even some of the synthetic methods tend to still get stuff like syngas from processing coal or natural gas.
Still, developing the processes and the scale to bring prices down is important, and can be built upon with an eye towards replacing the biofuel feedstocks with CO or CO2 feedstocks, and can still spur on demand for more renewable energy (without the risk of the return on investment collapsing).
He said that governments had, through ICAO, targeted a 5% emission reduction by 2030 by using SAF. However, he cautioned: “To be blunt, there is no path to meet that outcome.”
The 2050 goal seems far enough away that success or failure can be hand waved away, from the perspective of the goals being announced in 2021. But they set a goal for 5% by 2030, and it is concerning that we haven’t seen sufficient advancement in scaling up production of sustainable aviation fuel.
I’m most interested in fuel production being an energy sink for excess solar power. If we can set up a system where we overbuild solar electricity capacity far more than what we’d need on any given day, but divert some of it to storage (for use at night) and use some of it to produce chemical fuels with stored chemical energy, a large enough operation might be able to support demand for solar panels without jeopardizing the grid with too much waste electricity (and the economic side effects of producing something fleeting that nobody wants to pay for in that moment).
Isn’t that also true of the word “mathematics” as well?
I like gas for certain types of cooking, especially those that involve actively flipping things in the pan. And even when I switch to induction some day, I’ll still have my outdoor pizza oven, charcoal/wood grill, and, if I’m not gonna have gas indoors, probably a gas wok burner.
For anything involving wet heat (boiling, blanching, braising, steaming), anything involving the oven, and even deep frying, I’m looking to switch eventually. But for now, I do enjoy cooking on gas.
