or does it make more sense to have local solar power fill up some hydro dams we can drain at night?
Hey, any Electrical Engineers or anyone with knowledge on electricity transmission: What are the energy losses per kilometre when distributing electricity? For example if 1kJ of energy is produced at location 'X' & is to be consumed at location 'Y' ('Z' km away) how much is lost? Also is this a demand/time dependent number and if so is there an average? Looking for a captain! Thanks in advance!
Do any of you know what % of North America’s transmission lines, BHE owns?
With mass adoption of EVs on the way, it seems owning the grid will initially be very capital intensive (upgrades)… and then a brilliant investment. Thanks
Please correct me if I’m wrong, but electricity wants to return to the earth, so does that have any “pull,” so to speak, that can be measured?
I know that power stations transmit electricity over long distances at high voltages to reduce power loss as current will be lower. I understand that this is because of these 2 equations:
Power= V x I
Power loss= I ² x R
So I understand how the above works. But when I look this equation:
V= R x I
I get really confused because it seems to suggest that current will increase when voltage increases. Unless resistance isn't constant, in which case resistance will increase when voltage increases?
I can only think of one potential explanation for this, which is:
[V= R x I only applies in a closed circuit]
But aren't power stations transmitting electricity in a closed circuit? That's why there are two pins in an electrical plug isn't it. The current will eventually make it back to the station with 0 voltage. So V= R x I should still apply.
I'm just really lost as to why this seems like a contradiction. I think I'm misunderstanding something. Please help me thanks.
