Be super productive and your energy use rises also.

A single sector as an example.

It is harvest time in the upper half of the united states, the average farmer burns about 5.2KG of fossils fuels to produce 50KG of corn from opening the field to the local sale point. Another 2.5KG of fossil fuels is burnt to deliver it to the ports, and another half KG to deliver to international markets, before similar amounts of energy are used on transport to get it to foreign end users.

For that effort the farmer is rewarded the cash ebullient of 9KG of fuel, with that they have to upgrade and maintain their land, pay taxes, machines and pay themselves for the effort. 83% of farming is direct or indirect fuel costs (fertilizer is just another fuel), add another 10 for source materials and seed IP that is also largely past fuel consumption. Some of the most productive food growing in the united states is counted as per capita fuel consumption by Americans when 15% is shipped away as grain and another 5% to 10% is shipped away as manufactured products. If there were a more efficient way to produce food, the corporate farmers would have already adopted it.

Think as you grow up and learn how the world works, you will find when people are paying the energy bill vs paying themselves they do typically make their efforts as efficient as they can. You will also figure out the marketing, logistics and local packaging has more to do with end user cost than what is immediately visible.

If one uses multiple time servers, detectability of one set being skewed is 100%. There is no reason a device cannot use 127 time servers at the same time from around the world to confirm the time they are getting is accurate, only problem is a nation blocking access to the rest of IPv6 space via a firewall. Skewing time of either the server or the client more than 1 hour stops HTTPS/TLS cold.

The Youtubers with their own app for rating charge experiences say 80% for every vendor except tesla, 90% for Tesla. Match's the number of pumps that work in southern California at your average neighborhood retailer, or perhaps the 3 days a year everything is frozen in Western Michigan and the pump is taken out by the ice sheet in front of it.

The real problem is when the entire station with 10+ EV chargers is tripped, on the road between LA and Vegas and the service attendant is 150 miles away with the linecard that is needed to restore service. There are 30+ other EV chargers in the same zipcode, but those are filled with Walmart Shoppers.

People need public chargers when the impact of oversubscription is most notable. Wait I have been here for something before, ISP, AIRPORT, Dinner in Vegas. The public will pay out the nose for priority in this situation so this will be solved by private industry, but the internet will bitch. So here is the impact, the lowest income people with a EV will toil with their cars in a line. The middle class will overpay to use priority over the "piss on them" to use use the infrastructure with capacity to spare, and the Upper Class have already bought the Rapid Charger for home use, because who can bother to plug in for more than twenty minutes.

The math is quite easy. I spend about 10 minutes a week at a gas pump to pump 500 miles of range into my box on wheels.

My neighbor spends 12 hours (720 minutes) per week to put 500 miles of range into his box on wheels.

My other neighbor spends 90 minutes at a high rate charger to put 500 mile of range into his box on wheels.

My last neighbor spends 10 minutes per week at the gas pump to pump 500 miles of range into his box on wheels.

Its really easy to calculate the ratios...... Its 9 to 1 faster at gas pump than a EV quickcharger. It is 72 times faster at gas pump than EV home charger. You will need at least 4.5 more quick chargers and 50 time more home chargers. Not going to get done by 2035 if the remainder of the US stays in the hunt for EV charging equipment. If all the resouces go to california for 2035 and the state issues 10k tax credits for home chargers and 100k tax credits for public EV, they just might be able to support 100% electric miles in 2035.

California only has 25 million cars to replace with EVs.... So 15 million home chargers and one hundred thosand EV quick chargers.... A cool 150 Billion for home chargers and 10 Billion for public chargers...so about 8 grand per tax payer. Compaired to the train, many more use it, and many more benefit. So the family of 2 owning a households vote will be to take 10k in tax credits offset in 8k of a special tax. So the RENTERS, will not get the tax credit, their landlord will be able to see if they can get a rapid charger installed in their space for 100k per, to be used by their tannates only. Like the Laundry of old, figure out what you are doing at 3am, your up for 90 minutes to let your dog....er your car out. Perhaps the homeless will not recycle the cord.

The home user.... as opposed to $8 gas, will just pay for the install right off their breaker panel and run the cord across their property, or pull the car onto the lawn, not like they can use the sprinkler system. CA could also force the utility to install the outlet right at the house shutoff and the homeowner can run 90 feet of 100 dollar per foot cord and be better off than paying the tab on a EV charge install.

Comment If Wind and Solar is better, write the contract (Score 2, Interesting) 131

If I have half a billion burning a hole in my pocket, and in progress on a contract to build a data center, I would want the power agreement tied down before the land clearing took place, because I would be spending another half billion in operations over the next 7 years. Getting the local utility company to extend the grid to my selected location is a matter of 6 weeks of communications and the construction to lead off with the building of substation to the utility companies requirements. The solar company or wind company that wants to sell my data center power and be backed up by the utility when the sun does not shine and the wind does not blow. The utility has a rate to provide this highly variable service, it is far in excess of the fixed rate that I expect to pay for my datacenter, as my customers in the data center are fine with 20cents/KWH and I am fine with 18cents/KWH daytime rates. My customers expect 10/KWH at night, Ill live with 9/KWH to pay for the power part of a data center. The solar and wind companies can offer me 16c/KWH daytime and perhaps just pass through 25c/KWH night time from the utility. Not one of these people have told me of the 10032c/KWH they are going to need to invest in storage.

This is exactly opposite the demand curve. The only thing I can offer as the DC operator is that 80-160 hours a year I would be willing to fire up both my A and B side generators and use a bit of my UPS lifetime to cut my load off the grid. The utility at least has to guarantee me that they will pay for the NG cost for the generators.

If I were building 10 data centers that could be turned on and off in 10 minutes, cheap unreliable power would be attractive, attractive enoght to hire weather forcasters 24/7/365 to tell me top up my 10 minutes of backup power at prime rates because it certain that the automation will flip the switch. But I am building 2 data centers to finance the other 8 over the next 20 years, it is right there in my business plan. With a pair of small power plants within my grid operator footprint, I do not have to invest a ton in storage and THE COSTS ARE FIXED UP FRONT. My investors only risks are returns on AI vs inflation and interest rates. If someone is willing to produce a must deliver contract at anything under 15c/KWH and pro rate that with inflation as a data center, they have a customer of the datacenter and their tenates. The data center clients are free to have a contract with the utility and the solar wind to shut down compute for a fee/hr, those clients can offload to my competitor, I really cannot write a contract telling them they must.

I have to figure when I am contracting power for the 9th and 10th data center, the power provider has figured out how to make this deal profitable. The weathermen are already on payroll, so that is a fraction cheaper per region. Most importantly I have a standard contract to take to solar/wind provider, the nuclear competitor has figured out the downsides, the utility has gotten over dreams of windfall profits and the customer of the data center has figured a strait forward load shed agreement with both the DC operator, the utility and the provider.

Or a Power Plant operator can sign a fix rate contract with a data center to maintain 92% utilitzation of a stated max for 10 years with the rate specified at the time of signing. Any growth is on another contract, directly related to the cost of construction. Nuclear or NG, 10 year contract with a 10 year option for 99.99% power uptime is 3 pages of tables on a contract. Solar, Wind has to be able to offer the same known cost and that same 99.99 uptime.

Comment Only a few significant cables south of Eq. (Score 1) 6

This is south of the equator Africa, much different than the Med and North Africa. The other repair ships are in the Persian gulf, red sea and med as the base of operation. The primary place this ship will service is the Madagascar and Tanzania. Many of the closer islands it is cheaper to put up a microwave link and back it up with multiple sat vendors. There are not a lot of underseas cables that are solely critical, perhaps handling the contract after a break will be expensive, but not be critical.

The overland routes are becoming many as most of the African Nations have power systems with interconnects that are supported by fiber optic networks and are accessible and leased as either managed solutions and perhaps dark fiber to qualified vendors. Once someone maintained the roads along the power system, these links were financed by the cell phone providers nearly 15 years ago. The whole earth motherboard of wired mag describes 25+ years ago was a snapshot of a buildout wild west that was gone just two years later. I would say rural africa is better connected by fiber service footprints that the united states in 1992 by T1s, OC3s. It might be much more of hassle to get into the connection point in a few of the nations, but at least its not putting up and keeping the power on a series of microwave links of the early 1990s.
