Gridstatus.io gives a nice picture of how regions of the U.S. differ. California is mostly renewables during the day. The Bay Area is cloudy today, but statewide solar is 52.0% of the grid. Fossil fuels are at 22.7%. Texas (ERCOT) is mostly wind right now. East coast is indeed heavy on natural gas. California and New York both have shocking electricity costs. Part of the cost is from the renewable build-out. We’d be much better off pushing out monopolies in favor of large-scale cooperatives.

A bit outdated In 2024, India has 57% from fossil fuels and 43% from renewable sources. Coal usage is 49% in India compared to 61% for China (as per Statista) FYI: The USA has 60% electricity generation from fossil fuels. https://powermin.gov.in/en/content/power-sector-glance-all-india https://www.eia.gov/tools/faqs/faq.php On Wed, Feb 14, 2024 at 2:23 AM Marcus Daniels <mar...@snoutfarm.com<mailto:mar...@snoutfarm.com>> wrote: Not great!

All households in Delhi get 200 free units per month per meter, and the next 200 units at 50%. We have 2 meters (1 for lighting and 1 for power), so 400 free units and 400 more at half price. This winter was a bit colder than usual so I exceeded the free allowance in December on my power meter. and had to pay $15. It also helps that our Govt was pragmatic and kept buying cheap oil from Russia.

That greatly sorted out the problem. I believe the meter design was also changed to ensure that the Hall sensors were inserted into the phase as well as neutral lines. Here are some links. https://www.derc.gov.in/sites/default/files/Public%20bulletin-5.pdf https://www.derc.gov.in/sites/default/files/TechnicalspecificationforMeters_0.pdf https://www.derc.gov.in/sites/default/files/Draft-Regulations.pdf (for Page 16 of 80) Just for your information, In the past 1 year I have paid a grand total of about US$ 150 in electricity bills for an annual consumption of about 3,600 Kw-Hr (3,600 units).

If interested I can send the full paper abstracted here: https://ieeexplore.ieee.org/document/8077940 There is also a thesis from the same group that gives more info.... The paper makes clear that one of the preferred technologies in electric meters (the Rogowski coil) can go haywire when nonlinear loads are present. The smart meters gave readings up to 500% higher than the actual usage. The meters PNM has proposed for its entire territory is the Itron "Gen5" Riva, which has been deployed in the last 2 years in Denver and parts of Texas. Sure enough, some customers' bill have gone way up (3 or 4-fold in one news report), and they have little recourse: https://www.youtube.com/watch?v=dpOhTXV59pI&t=20s I intervened in this PRC proceeding last year, and may be able to get this info onto the record, and try to get the PRC to require better testing on nonlinear loads. But I need someone with some relevant expertise (can be education or experience) to explain the published findings and their implications to the PRC in an affidavit by March. This person would then answer questions from the PRC and possibly PNM via zoom in a short hearing in late April or May. I have several reasons for not wanting to see PNM make this huge investment (and by law they are entitled to a nice rate of return paid by us, the customers) in a very messed-up technology. Probably most of us in this group don't sweat much about our electric bills (actually maybe if ours quadrupled, we would), but for low-income families, this is potentially very cruel, since the cost of the meters will be charged with interest regardless of usage, and energy-saving appliances typically have nonlinear load usages). I hope to be at the St. John's gathering Friday am, but feel free to reply or contact me directly if interested in this. --William J.
