heygrady··on Tesla Model 3 Ramp Up Aims to Compete with BMW 3 and Mercedes C
Renewable power generation may already be cost competitive with fossil fuels [1]. It's gaining popularity in developing nations for this reason [6].

Natural gas, which is leaked heavily during fracking [2], is an order of magnitude more harmful than CO2 in the short term [3]. But it breaks down far faster in the atmosphere [4] and is comparatively better than coal when it's burned [5]. Thankfully, fossil fuels are losing to cleaner technologies [6].

Cheap renewables, like solar, allow EV owners to opt-out of centralized power generation and charge their cars with clean power [7]. One could argue that this is the entire business model of Tesla [8].

> Driving electric cars where the electricity is from unclean sources is not better than hybrids for the environment

Some of the widely reported research about the power generation and electric cars is flawed [1]. Electric vehicles and hybrids come out about even in the worst markets, like Missouri [2]. But nearly everywhere else, an electric vehicle is better for the environment. People don't always consider that the electric grid is moving away from coal [3], which means your electric car will get greener during the time you own it without you having to upgrade it.

Hydrogen is unlikely to win, it's fair to say that it has already lost [1]. The hydrogen economy was mostly a myth [2]. 95% of hydrogen is made from natural gas [3].

Coal isn't the cheapest [1]. Natural gas is cheaper because of fracking. Renewables have been reported to be cheaper than fossil fuels for the first time in 2016 [2]. Electric vehicles are cleaner than gasoline cars almost regardless of where the electricity comes from [3]. I think in Missouri EV are on-par with gas because Missouri has the dirtiest power plants.

heygrady··on Solar Now Provides Twice as Many Jobs as the Coal Industry
According to the article, they are not highly skilled workers.

> Many of the jobs are also accessible to people who might otherwise struggle to find well-paying jobs. An entry-level worker without a degree can conceivably double their salary within a year, from $10-$12 an hour for simple manual labor to $20-$23 an hour. The median wage posted for solar installer jobs in 2016 was $26 an hour.

"States rights" is widely viewed as a racist dog-whistle [1]. States rights doesn't have to be racist, although it is very often linked that way [2].

The war on drugs was instituted as a racist policy [3]. It's quite likely that the main motivation here is using drug laws to punish people of color.

heygrady··on It May Not Cost You More to Drive Home in a Climate-Friendly Car
Sorry for mentioning Tesla. I realize it's an annoyingly expensive luxury car. The larger point is that getting a "usable" firstgen EV required getting a luxury car. A nextgen EV with 200+ miles of range will be available for "affordable" prices by the end of this year (from Chevy).

EV incentives weren't meant to be unsustainable. That's why they're limited to 200k cars per manufacturer. Tesla will be the first EV maker to become ineligible for tax credits because they will have hit the limit. They're also the first EV maker to deliver a car that keeps its value. Others will follow this year and next.

Get a used EV! The Nissan Leaf is highly recommended as a used car. We have to build new ones -- and sell them -- before there are used ones available.

Your argument is pretty thin. I would imagine the best way to alleviate your concerns would be to require aggressive recycling programs for an EV.

Long-term, the sale of these cars is allowing the EV market to mature. Already the price of the batteries has gone way down. The nextgen EVs coming out this year and next with 200+ miles of range were only made possible by this "unsustainable" consumer good. Maybe my 2012 EV with 75 miles of range is already in a land-fill somewhere. But a car like a Tesla S keeps its value surprisingly well and should last for quite a while.

The Chevy Bolt is a compelling car that someone could own for a decade. Your main complaint is that the cars are evolving so fast that there are better options available every time your lease is up. Big deal!

I think the battery is the most hazardous component. It's also the most valuable from a recycling perspective.

Firstgen EVs are not popular in the aftermarket: http://blog.caranddriver.com/tesla-aside-resale-values-for-e...

Battery recycling is an emerging market as well: http://www.greencarreports.com/news/1093810_electric-car-bat...

heygrady··on The price of solar power just fell 50% in 16 months
http://cleantechnica.com/2015/08/10/adding-energy-storage-to...

You can add a battery backup system to cover night-time usage on your own home. The $10k battery system basically doubles the price. But since the solar panel's price just dropped by 50%... Cloudy days you might still be in a deficit.

What is so wrong with a mixed system that uses renewables where it makes sense and relies on other sources to fill in whatever gaps appear?

Looking at the rapidly flickering LED image I imagined an engineer showing the data to his manager, "well, a real candle looks like this: kind of sedate and boring." Followed by the manager insisting that it gets a little livelier, saying something like, "if people can't see it flickering they'll thing it's broken. Make it very obvious that it flickers. I don't care if it looks real. I care that people can tell it's flickering"

heygrady··on VW emissions scandal hits 11m vehicles
I liked this article from 1989: http://www.straightdope.com/columns/read/832/do-cow-and-term...

> Methane breaks down in the atmosphere to form carbon dioxide, ozone, and water, all of which absorb heat.

Almost every current article about cow burps cites a 2006 U.N. study saying that livestock accounted for 18% of methane pollution. That study was later called into question as being slightly exaggerated because it included pollution from farming infrastructure itself, not just the animals.

http://www.telegraph.co.uk/news/earth/environment/climatecha...

> The meat figure had been reached by adding all greenhouse-gas emissions associated with meat production, including fertiliser production, land clearance, methane emissions and vehicle use on farms, whereas the transport figure had only included the burning of fossil fuels.

heygrady··on VW emissions scandal hits 11m vehicles
... like the gas used for farm equipment? Or the fossil fuels used in some fertilizers? Sure. It's a common talking point to mention "cow farts" and "cow burps" because they emit greenhouse gasses. But generally the greenhouse gasses emitted by cows are from the organic matter that they were fed.

Excluding the farm equipment and fossil-fuel-based fertilizer, cow burps form a natural closed loop. Meaning, grow corn or grass and it takes in greenhouse gasses from the soil and the air. Feed it to a cow and it releases those same greenhouse gasses.

Cows and plants by themselves are not actually contributing greenhouse gasses into the atmosphere in a manner that contributes to global warming. Meaning, if you're worried about cow burps or humans breathing... stop worrying about it. And if you're pointing out that animals emit greenhouse gasses... cool, but that is irrelevant to a rational discussion of emissions that lead to climate change.

For agriculture, the system becomes imbalanced when you add in the emissions of the industrial farm equipment and the shipping infrastructure to getting food from the farm to the the table. But that imbalance is what we're trying to address when we talk about transitioning to more fuel efficient vehicles or more sustainable farming practices (like not using fossil fuels in fertilizer).

So, mentioning agriculture as a polluter is typically a red herring. At first blush it seems reasonable because there are a lot of farm animals that emit greenhouse gasses. However, including agriculture in a discussion of emissions is usually disingenuous or misinformed.

Cows eat grass, not fossil fuels. Measuring the impact of agriculture vs. transportation should take the source of the pollutants into account.

heygrady··on Examining the Black Family in the Age of Mass Incarceration
> It's just wrong? That's it?

I would presume the author is rejecting a handful of stereotypes in the quoted statement. I think the author was rejecting the sexist undertones of men being preferable to "women telling [kids] what to do". And the sexist undertones of introducing young men to "a girl who looks like Diahann Carroll." And the tone-deafness of "meet them with a real estate agent." Maybe the author thought showing Vietnam Veterans "a list of jobs" was also tone-deaf.

1) In the earlier article about reparations, there was a large section about real estate red-lining. Importantly, minorities were not allowed to buy houses outside of designated areas. http://www.theatlantic.com/magazine/archive/2014/06/the-case...

2) There are any number of reasons that a military veteran may have difficulty finding a job (PTSD?). Suggesting that they simply haven't looked is a little bit insulting. http://www.washingtonpost.com/news/wonkblog/wp/2013/11/11/re...

3) While there are numerous claims of the importance of male role models, these arguments are dubious. http://www.amazon.com/Raising-Boys-Without-Men-Exceptional/d...

4) I presume the bit about Diahann Carroll is suggesting that black men would get married and stay married if they met a sufficiently sexy woman. I think most people would consider that to be insulting.
