Or getting mad at oil & gas companies? They’re only supplying the fossil drugs we demand. And using their billions in profits to lobby at every level of government and society to ensure they can continue despite the scientific evidence of harm that they’ve known since the 70s? Not at all like that.

Quite a few countries (France, Spain, Italy for starters) require seat reservations in advance for any long-distance/high-speed trains now. And worse, they have a quota for passes, so even if the train has space, you might not be able to reserve a seat and therefore get on the train. A real shame as it makes it far less flexible than before.

The EFI partition is unencrypted.

“you don't even need to plug an external storage device, you can just pull out the disk, copy the files in the EFI partition, put it back and it will still work. That's how bad it is.”

Estimates suggest they could save U.S. consumers billions of dollars a year in electricity costs, while potentially offsetting thousands of megawatts of demand (https://www.sciencedirect.com/science/article/abs/pii/S09601...)

Plus it increases equity because this primarily opens up solar for those in rented accommodation and apartments/flats who otherwise couldn't access it. Personally that feels well worth pursuing if it's deemed safe.

Until recently, the geographical locations where geothermal is feasible and economic was very limited. Ironically it is tech from fracking/shale gas that is starting to open up a far wider range of possible sites at lower cost.

Baseload is traditionally about generation, not consumption. And baseload generation only makes sense when it is the cheapest option.

When solar and wind produce at near-zero marginal cost, running inflexible baseload beside them just forces cheaper generation to switch off, driving up system costs.

What the grid needs is dispatchable capacity - batteries, hydro, gas peakers (if we must) and demand shifting - that can plug the gaps when cheaper forms of generation cannot.

Most solar arrays that are built still feed into the general electricity grid, as I understand it. So while the PPA has likely enabled the construction of the solar, you'd still need to consider the overall carbon intensity of the grid at the time of energy consumption - and hence the SCI incentivising direct reductions by making software carbon aware, and encouraging higher efficiency.

If the data centre entirely off-grid, the SCI permits using your own grid intensity factors.

I'm not clear on the scenario where the solar is directly connected to the data centre 'behind the meter', or if there are other forms of peak shaving, while still drawing on the grid when needed - does anyone else care to comment/clarify the standards intentions there in terms of incentives?

Why do we need such a thing?

For starters, growing numbers of companies are required to report on their own emissions, which includes software - and therefore having agreed standards on how to measure this would seem a good way forward to me?

carbon emissions are also proportional to energy

Reducing energy usage reduces carbon emissions, but they are not proportional. Highly dependent on the grid composition, time of day you draw the energy, and any behind-the-meter infrastructure.

and all large operators do catalog and reduce GHG emissions.

To take AWS as an example, they still do not report scope 3 emissions for customers (due 'early 2024') - without which, these 'catalogued' numbers are essentially meaningless given how understated they are.
