- Does it make sense to use MWh h as unit of measure?
As people are generally billed in kWh or (MWh for big business?) it is simpler to indicate the a unit of power per time period * kWh and MWh are alternatives to joules for representing an amount of energy, * kWh h and MWh h are alternatives to kW and MW for representing power (or energy production consumption)

I have various datasets of energy production in MW I need to present everything in MWh I need to know if my data is already by the hour (logging a value for each hour of each day of an entire yea
- MW versus MWh is one total capacity and the other maximum output?
So 7 MWH is how much energy (also termed "capacity") the battery contains MWH another unit of energy and can be directly converted back to joules In summary, two batteries with the same MWH rating will go the same distance up the hill before running out of juice One with a higher MW rating will get you there faster

- Why is power specified in watts rather than amperes?
Laptop batteries tend to come with a bunch of different voltages even for the same laptop and will get converted to the operating voltages using largely power-preserving buck converters So there is little point in specifying them in terms other than Wh (or mWh) Not every specification is done in the most sensible manner, of course
- What is the valid capacity ranges of Lithium Ion 18650 batteries?
I'm seeing wildly varying capacities that are seemingly fake on 18650 cells, such as these "9,800 mAh" ones on eBay, but are ~$1 cell However, 'genuine' cells from Panasonic and similar name br
- What does a 10MW wind turbine mean? - Electrical Engineering Stack Exchange
0 So if a wind turbine has a capacity of 10MW, what does that exactly mean? does it produce 10MW every hour, or is it the peak power it can generate at any time? the following question is how to know how much MWh does it produce in a certain time-frame (lets say 24hrs)?
- Relation between C-rate and power of a battery
5MW (power) 5 MWh (capacity) 5MW 10 MWh So the definition of the c-rate is: A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity A 1C rate means that the discharge current will discharge the entire battery in 1 hour So for the second storage, a 1C shouldn't be possible?
