Highlights: A study this summer found that using a single gas stove burner on high can raise levels of cancer-causing benzene above what’s been observed from secondhand smoke.
A new investigation by NPR and the Climate Investigations Center found that the gas industry tried to downplay the health risks of gas stoves for decades, turning to many of the same public-relations tactics the tobacco industry used to cover up the risks of smoking. Gas utilities even hired some of the same PR firms and scientists that Big Tobacco did.
Earlier this year, an investigation from DeSmog showed that the industry understood the hazards of gas appliances as far back as the 1970s and concealed what they knew from the public.
It’s a strategy that goes back as far back as 1972, according to the most recent investigation. That year, the gas industry got advice from Richard Darrow, who helped manufacture controversy around the health effects of smoking as the lead for tobacco accounts at the public relations firm Hill + Knowlton. At an American Gas Association conference, Darrow told utilities they needed to respond to claims that gas appliances were polluting homes and shape the narrative around the issue before critics got the chance. Scientists were starting to discover that exposure to nitrogen dioxide—a pollutant emitted by gas stoves—was linked to respiratory illnesses. So Darrow advised utilities to “mount the massive, consistent, long-range public relations programs necessary to cope with the problems.”
These studies didn’t just confuse the public, but also the federal government. When the Environmental Protection Agency assessed the health effects of nitrogen dioxide pollution in 1982, its review included five studies finding no evidence of problems—four of which were funded by the gas industry, the Climate Investigations Center recently uncovered.
Karen Harbert, the American Gas Association’s CEO, acknowledged that the gas industry has “collaborated” with researchers to “inform and educate regulators about the safety of gas cooking appliances.” Harbert claimed that the available science “does not provide sufficient or consistent evidence demonstrating chronic health hazards from natural gas ranges”—a line that should sound familiar by now.
I hear a lot that gas is cheaper for heating and I took that as the truth for a long time. A while ago I did the math though, and for my house is would have been nearly the same annual power bill if I replaced my 90% gas furnace and water heater with electric units. Although the price of gas is far more economical for heating, there's a monthly gas usage fee that's a flat rate. If you go all electric, you don't pay that, and over the course of a year, I didn't heat enough for the lower gas price to offset the flat fees. If instead of a regular electric furnace and water heater, they were heat pumps, electric would have been much cheaper than gas.
This certainly would depend on your local prices and weather and how well your house is insulated, but if you need a new furnace, I'd do the math over a year to see if gas is still the most financially attractive option, especially if you can install an air or ground source heat pump.
Heat pumps are so stupidly efficient that my coworker didn't believe it, even when I showed him how it worked, lol. They are the SSDs of heating and cooling, particularly ground source ones. I had an apartment with one and loved the $60 summer power bills. God, it was fantastic. $60 for the AC, hot water, gaming PC, washer/dryer/dishwasher, oven, and lights.
...And no worries of a gas line leaking or carbon monoxide poisoning.
I heard that geo heat pump installation cost is very high. Did you do the math to see how many summers of $60 energy bills it will take to recuperate initial investment?
Geo heat pump install is indeed very high. But air source heat pumps (both heat pump water heaters and heat pumps for heating/cooling) don't have that issue and have similar performance, except in extreme climates where geo outperforms.
They perform similarly in terms of heating a cooling ability, but ground source heat pumps are much more efficient. It's still a tough sell though since the installation costs are huge.
Modern air source pumps work down to -17 degrees Farenheit even without resistive heaters. It's something to consider, but it's not a concern for most people.
Even in extreme climates, air source can have resistive heaters built in for emergency heat. Doesn't save you nearly as much money, but it will keep your house warm when the temperature drops to -38f for a week or so. :)
It worked quite well when I was living in Montana.
