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

A bit outdated In 2024, India has 57% from fossil fuels and 43% from renewable sources.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

Thanks for that info Sarbajit. The Hall effect meters were found to be quite accurate in the work in Europe. It's the Rogowski coil models that can be way off. It's also possible to manipulate them into thinking your bill is zero or negative (without solar panels!) if you find or make a load with

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.

Hi Bruno Smart meters were mandated in New Delhi India in 2008 onwards and we had the same sort of consumer experience with bills shooting up due to these then "made in China" meters and there was tremendous consumer anger. 2 important changes were made for domestic consumers - a) Billing would

I'm hoping some Friam member who knows a little about how an electric meter works will be interested enough to get this addressed BEFORE PNM spends $ 300+ million giving us all new meters. If interested I can send the full paper abstracted here: https://ieeexplore.ieee.org/document/8077940 There
