Our Primes don't seem to be helping

Cows are adept at kicking forward, so it doesn't matter.

 

My dad's cows generally kick forward mainly to prevent being milked (they are not dairy cows). They don't slash with front hooves as deer do, but can perform serous head-butts. As for methane emissions, the front is no more offensive than ordinary bad breath. The rear has other more immediately noxious emissions.

 

Yes, it is the Northern Hemisphere's growing season cycle.

Not just cars, but an approximately 80% reduction in all our carbon emissions.

Most of us use more energy in our houses than in our cars. Food and consumer goods represent a lot more carbon to produce and transport. Airplane travel is also carbon-intensive and growing much faster than cars are reducing their carbon use.

Personally, I have driven my home's net carbon use all the way down to zero, first by being an all-electric house serviced by a net-zero-carbon utility, then compounded by also producing enough solar energy to become net-zero-energy as well. But that success applies to only a single sector. My Prius represents only a 50% carbon cut for a single vehicle in a multi-vehicle household. A second vehicle is only about 20% better than its predecessor. Then all our other carbon-emitting sectors -- food, commercial goods, air travel -- need a lot more work.

 

Industrial and office energy usage is also pretty substantial.

 

Then some cows can still have horns.
Since they are doing the cellulose breakdown fermenting on the front end, there is likely a fair amount of methane coming out that way with all the cud chewing.

 

It's not farting, but belching that releases 90 to 95% of the methane. I'm surrounded by conservation land which is frequented by deer, which are also ruminants (cud chewing methane machines!) and, as an amateur astronomer spending many hours under the nighttime sky am no stranger to their belching, which occurs mostly when they lay down to re-digest the cud (they are so tame here that they have no compunction coming right up to you).

 

Especially if they've been eating a lot of spring alfalfa.

Dad would usually raise a cow every year or two for beef. We had one calf that cut its foot so it was my job to give it a preventative injection. I had him in a neck hold device but as I jabbed the needle in the tough hide, he decided it was time to leave town. The syringe and needle were still stuck in his butt. I had a rope on his neck and held on for dear life. That "little" 300 lb calf drug me all over the "back forty" like I wasn't there for a good 20 minutes. They have pretty low center of gravity compared to me. I just wanted to get the needle out. I finally was able to get him by the neck and get the needle out without injury to hm or me. This all happened pre-Internet or it would have been a YouTube sensation.

 

I always found this map to be interesting. Not sure how accurate it is, but it gives you some insight into where CO2 (edit: CO) emissions come from: Windy: Wind map & weather forecast

 

That's carbon monoxide, not dioxide. Still worth tracking. I love windy for lots of other stuff, didn't know about that layer. Thanks!

 

Ahh I knew something seemed odd about it. Thanks.

 

Wow, glad I’m not living in the NE.

 

Fill me in if I'm wrong but just how does driving a Prime/Leaf/Tesla help if your not 100% sure it's being charged from Solar/Wind etc, generated electricity? Otherwise your just rolling on coal/natural gas aren't you?

 

Electric drive is typically 4-5 times more efficient than ICE. The grid gets cleaner every year which makes it better over time.

SM-T380 ?

 

Our region is heavily relying on nuclear which has it's own problem, but at least low CO2 emitter. I pay an extra fee to buy renewable energy from my choice of supplier.

 

In short, it’s still more efficient in most states. Check out

.

Power plants are *a lot* more efficient than a space- and weight-constrained car engine. Also, in many cases, what they burn is less pollutive (a lot of US power plants these days burn natural gas, for example).

Another big piece of that is that power plants can, almost always, operate continuously at peak efficiency, whereas gasoline engines are required to spin up to high RPMs for acceleration, or sit idling, etc.

It’s pretty amazing just how inefficient pure-gasoline cars are. Hybrids improve that, of course, but power plants are considerably better still.

 

You sure about that? PNPS shut down permanently a few weeks ago. That was MA's last nuclear plant, and it supplied about 1/8 of the commonwealth's power. You've still got Seabrook & Millstone in NH & CT.

 

Efficient by what measure?

 

I personally didn’t post those numbers, however, charging a BEV at home and then delivering that power to the road, all told, works out to about 75% efficient (

).

Meanwhile, a pure-gasoline drive train only occasionally gets to better than 25% efficiency. Remember that the current Prius’ “40%” efficiency is *peak* efficiency; gasoline engines, especially in pure-gasoline drive trains, are very rarely able to operate under ideal conditions. Hybridization helps considerably, but still doesn’t close that gap.

Even modern ICEs are amazingly inefficient.
