Renewable energy met all new demand for electricity in 2025, according to a new review of global power generation, halting the growth of fossil fuel-powered generation and highlighting the promise of clean sources like wind and solar.
The authoritative Global Electricity Review released annually by Ember, an international energy research organization, says clean sources — especially solar — are growing fast enough and are cheap enough that they are stopping new fossil fuel-powered electricity generation. Electricity from solar and wind increased while there was no change to the amount of electricity produced from burning fossil fuels.
“We’re really talking about a large-scale change in how the energy system works. And solar is among the most scalable technologies that can deliver fast change,” said Nicolas Fulghum, senior data analyst at Ember.
Micro hydro this is feasible. Many tall buildings already have water tanks near the top.
Sorry i wasn’t speaking micro, I’m talking like lake and river scaled hydro. Some places even build reservoirs specifically for pumped solar storage.
I’m just thinking they should install micro hydro on buildings that have raised water storage. Recapture some of the energy it took to get it up there.
A 4” pipe with 400’ of head altitude feeds a 3/4” nozzle pelton wheel with around 7000w @ 120v in a basic bush install. I am sure a well engineered system could provide double that or more, but a rooftop tank might run out at night unless it was quite big, and that is definitely micro hydro.
calculations based on living with such a system
That is not sensible, hydro storage needs to scale, so be very large, to be feasible. And that without having to build the supporting structure.
You’re replying to the wrong person.
how do you think that water gets up there?
Not solar panels. jfc what a weak ass reddit dunk. You should be ashamed.
