Using this data, “the team showed that about 17 teragrams per year of the increase is due to fossil fuels, another 12 is from wetlands or rice farming, while fires are decreasing by about 4 teragrams per year,” NASA said in a January 2 press release. “The three numbers combine to 25 teragrams a year — the same as the observed increase.”
Quote:
To conduct their research, the scientists examined the methane molecules linked to different sources, focusing on carbon isotopes in the molecules, which helped them match the methane to different sources. Methane molecules rising from wetlands and farms have a relatively small concentration of heavy carbon isotopes, oil and gas-linked methane higher amounts, and methane from fires the most heavy carbon. The scientists also cross-checked their findings by looking at other associated gases, like ethane and carbon monoxide — and the numbers all fell into place.
The part I put in bold is using the same technique I have shared on here before when in 1955 scientist Hans Suess proves fossil fuels (carbon 12) were diminishing natural carbon (carbon 14) in the atmosphere making this the first time it was made possible to measure with accuracy the accumulation of fossil fuels in the atmosphere.

So don't be fooled by our politicans when/if they say things like "climate change is still up for debate" and "the science isn't settled yet".

Nearly two-thirds of India’s coal power generation is no longer price competitive with new solar and wind projects.
Quote:
65% of India’s coal power generation in financial year 2016 – representing 94GW of installed capacity – was being sold to distribution companies at a higher cost than power from new renewable energy projects.
Quote:
The analysis showed that replacing the most expensive coal power plants in India with electricity generated by solar photovoltaics (PV) and wind can save consumers up to 54,000 crores ($8.3bn) annually.

Nice to see more and more of those in the oil industry understand and write about what is coming....

Quote:
But the exact date the world will hit peak demand kind of misses the whole point, argues a new report, which is notable since it is coauthored by BP’s chief economist Spencer Dale, along with Bassam Fattouh, the director of The Oxford Institute for Energy Studies.
Quote:
They argue that the focus shouldn’t be on the date at which oil demand peaks, but rather the fact that the peak is coming at all. “The significance of peak oil is that it signals a shift from an age of perceived scarcity to an age of abundance,” they wrote

Another real-life example of the grid changing for the better using battery storage.

[Only registered users can see links.]

Quote:
"When we ran the economics in this Punkin center case it came out pretty clearly in favor of the battery," he said.
Quote:
The project will provide local generation to Punkin on 20 to 30 peak demand days a year. "The rest of the time the conductor is fine," Ellis said.

On other days, the batteries will provide other grid services for APS, such as shifting renewable generation to peak hours. "In the spring and the fall the battery will be available to soak up low cost, negatively priced solar on the system at those times and then discharge it when the value of the power is much higher," Ellis said. "All those savings accrue to our customers."

Inga Beale, Lloyd’s of London chief executive, said: “That means that in the areas of our portfolio where we can directly influence investment decisions we will avoid investing in companies that are involved mainly in coal.

“Is there more the insurance sector could be doing to help the world transition to a low-carbon economy by choosing sustainable or low-carbon stocks?”

For those that want a nice summary of what's going on in the solar world, here ya go. It's a balanced article that gives slight possibilities of this working, but in the end:

Quote:
It takes months to build and set up a module assembly facility in the U.S. and up to two years to set up a cell manufacturing plant. Given that the tariff will only be in place for four years, and that it declines each year, there simply may not be enough time to open a U.S. facility in a way that makes economic sense. And the possibility that Trump’s tariffs could be challenged and overturned at the World Trade Organization doesn’t help matters.

This is a great 16 minute presentation from BNEF on the future of EVs. At the end, Colin shows a slide that gives this data point:

For 2016:

20.5 GWh - Battery demand of Global EV autos

BUT

16 GWh - Battery demand of just commercial EVs in China

This shows that while most of the media/analysts focus on car demand displacement, the kicker is commercial fleets.

Another real life example of businesses switching over to battery storage:

[Only registered users can see links.]

Quote:
Greg Sorensen, president of Liberty Utilities’ West Region, commented:

“Battery energy storage can facilitate use of renewable energy sources. Battery storage can also improve service reliability and help offset purchases from fossil fuel sources during times of high electricity demand, saving money for our customers. The Olympic Valley Microgrid project proposal is just one piece in a larger mosaic of renewable energy and battery energy storage projects that Liberty Utilities is exploring throughout our service territory.”

Our politicians were being called out in public form and could not take it. There is a short video of what happened inside the link:

Lissa Lucas traveled the 100 miles from her home in Cairo, West Virginia to the state capitol in Charleston Friday to testify against an oil and gas industry sponsored bill (HB 4268) that would allow companies to drill on minority mineral owners’ land without their consent.

Lucas took to the podium and began by pointing out that “the people who are going to be speaking in favor of this bill are all going to be paid by the industry.”

Just read the article and watched the video. I'm proud of Lissa Lucas for calling them all out in public. The corruption out there is crazy.

This shit will stop once there are enough EVs in the public hands and the oil industry isn't as profitable as they used to be. But this is why im so adamant about renewable energy and transportation - for too long the public has been brushed aside for profit and thats over soon.

We've been manipulated since the 1400s over our energy needs and the next decade will be the last. 2020-2030 is the start of the downfall of the dirty energy industries.

No wonder Trump wants to take funding away from using satellites to observe our planet....if you can't observe it, it's not happening, right? Therefore it's a non-concern for the public and spending......

Just wanted to post again and bring this back to the band/Dave's lyrics. I've started listening through different shows in different years to get back into this band before I see them again in May and Die Trying from LT 6.28.08 came on.

The lyrics can be applied to a lot of different things, but immediately thought about this subject.

Quote:
To change the world
Start with one step
However small
First step is hardest of all
So if you can't get solar panels and an EV right this second, start with something small - one thing, whether it's solar panels first, or an EV first, switching over to wind energy from your utility, or simply eating plant based burgers from Impossible Burger or Beyond Burger. (My wife and I just tried the Beyond Burger for lunch today and it's great). Not eating meet uses 95% less land, 74% less water, and creates 87% less greenhouse gas emissions.


Quote:
Once you get your gait
You'll be walking tall
That's what I've done.....we've been on wind for years now, getting an EV soon, and then in a few years adding solar and battery storage.

It feels great to know I'm helping the world become less toxic now and for future generations. Anyway....happy Sunday!

A little light Sunday night reading -

[Only registered users can see links.]

Quote:
The largest 200 companies that generate at least 10 percent of their revenues from clean energy have generated a total return of 32.1 percent in the past year-and-a-half, compared to just 15.7 percent for fossil fuel companies in the S&P 1200 Global Energy Index.
Quote:
Part of the dim outlook for oil and gas stocks, the report argues, is that investors are looking over the horizon and are starting to see the long-term decline of the fossil fuel era.
Quote:
“Oil & gas are stuck in a lose-lose situation, if oil prices go up then demand shifts to renewables, if oil prices go down they cannot make a profit, their reserves cannot be sanctioned, so they become stranded assets,” Behar said. “The great transition is inevitable.”

You know, just posting more of the obvious.

[Only registered users can see links.]

Quote:
more coal capacity closed in the first 45 days of 2018 than in the first three years of the Obama administration.
Quote:
In November, Charles Patton, AEP's executive vice president of external affairs, said the future for coal plants “is very limited.”

"You evolve and you learn, and technology causes you to look at the world differently, and that’s what you have to do -- you can’t get stuck in the past or with the status quo,” he told Greentech Media. “We’ve learned that and we’re moving forward.”

For anyone interested in seeing how the Model 3 is put together:





Highlights of some of his comments:

Quote:
Wiring:
"Mostly CAN with a touch of Ethernet (including BroadR-Reach single pair)."

Wiring reduced by having 3 body controllers instead of 1

*No fuses* in Model 3. All solid state virtual fuses. You don't actualy blow anything, you just trigger a software shutoff of the power until you reset the "fuse".

Display:
"Connected by a 2 twisted pair system called FPD link III. There is a 4-pin Fakra HSD connector on the ICE (computer) module behind the glovebox area that can be easily accessed"

Suspension:
Top suspension arm FRP, curiously enough.
Massive front stabilizer

MCU/ECU (computers, incl. autopilot):
Liquid cooled by the main glycol loop

Seat heaters:
"Rear seats do indeed have heaters and they are connected. Just no way in the GUI as yet to enable them."

Drive unit:
"The drive unit contains the Inverter, Switched-Reluctance motor, a gear-reduction, and a differential to split the torque between the 2 wheels."

"The RWD has a higher capacity inverter than the AWD. (800A vs 500A) I don't know if there will be a "P" version yet, but maybe that one would retain the 800A in the rear and add a 500A in front."

Front motor:

There's a giant hollow already just waiting for it. "Cavernous space. You could put a small child in here." Note for if you need a smuggling compartment...

Pack:
" I can tell you the voltage ranges haven't changed too much. BMS considers 100% SoC at 4.2v per cell but the bottom changed slightly; it's now 2.85v/cell for 0% SoC, whereas on S/X it was 2.5v/cell. Note that Tesla advises owners not to charge above 90% daily unless really needed, so that puts the top at around 4.1v/cell. There is also a bottom reserve of 3.5kWh that you can't touch."

4426 2170s, 96S46P arrangement, 4x modules

76kWh actual, 74kWh nominal. Possibly only 72.5 kWh usable due to the 3.5kWh "bottom reserve".

Max charge 192A**, max discharge 1200A (ED: this must be AC charging, as that works out to too low for DC (47-78kW). Max discharge equates to 294-482kW / 392-646 max theoretical HP from the pack)
Min bus voltage 245V, max bus voltage 402V
Max regen 46,9kW, max discharge 370kW

Cooling:
Mounted on sizeable rubber gaskets and with a lot of acoustic foam, to keep it quiet.

Weights added to the cooling fan to ensure that it's properly balanced.

12V battery:
45 Ah. Not sealed.

Heat exchanger:
"It's a plate stack type on top of the drive unit. Looks similar to the one I showed in the 1st video where the glycol is chilled by the A/C refrigerant. "

"Yes, and not only that, but if it is super cold and they actually need to add heat (the motor/inverter is super efficient, so not much waste available), they purposely run the inverter in an inefficient mode to generate excessive waste heat to heat the pack. S/X had a s***ty electric battery heater in the glycol loop and these seem to be very unreliable. So on 3 they basically did it with software!"

Build quality and engineering:
"I've taken apart hundreds of cars so far, and I find the 3 to be well put together and a lot of thoughtful engineering throughout. Particularly impressed by the high levels of integration as compared to S/X. Also going to a electric pump and filter on the DU means they want it to last a long time. Really, the only maintenance most owners will need to perform is adding windshield washer fluid and replacing tires. Maybe a 12v battery every 5 years. Brake pads should do 100k unless you do a lot of aggressive stops."

"I think you must be referring to Sandy Munro. He had a lot to say about the fit/finish and went on and on about how the first responders can't get to the cut loop. First off, none of the fit/finish issues exist on recent the cars I've investigated, and secondly, Sandy's focus on the cut loop is silly. In any accident that would need first responders to cut into the car, the HV system has already been totally disabled by the RCM (Airbag Computer). Anything that matters seems to be really good. I welcome more objective analysis though!"

General safety:
"The RCM (Airbag ECU) blows the HV pyrotechnic disconnect in the HV pack as soon as there is an accident. Easy to safe the HV system by unplugging one low-voltage connector."

"The HV system is totally isolated from the chassis, and if the BMS detects that the isolation has been compromised, (due to a short from chassis to any part of the HV system) it will open the contactors."

"The fire vents relieve any pressure inside the hermetic pack enclosure, and if there are any hot gases, the deflectors redirect them to a safe place. There is a cabin filter, but it's inside, so a post filter, not a pre-filter like the S/X have."

"There is a lot of redundancy in critical systems. I've seen it in the BMS, Brakes, Power steering Rack, CAN buses, and Power distribution (no fuses). I haven't had the drive unit apart yet, but I expect it to have some redundancy, or at least built with fault tolerance in mind."
