Energy Calculator
This calculator allows people to find out how RE can provide their electricity needs.
(1) How much electrical energy do you use?
Method 1: How much is your electricity bill each month?
(in $)
OR
Method 2: How much electrical power do you use?
(in kW)
(Use only
one
method at a time!)
(2) How much does electricity cost you yearly?
How much electrical energy do you use?
(in kWh a year)
How much do you pay for such electricity? (energy+taxes+delivery+demand)
($ per kWh)
(Note that an average American household uses 10,399 kWh of electricity each year.)
(Fill out both cells!)
(3) How many solar panels
or
wind turbines does your home (or city) need?
How many people live in your home/city?
(4) How much electricity should you expect to get from
solar panels
or
wind turbines?
SOLAR PV PANELS
Here are the 3 pieces of info, you must enter into the table:
(*) How
many
panels are going to be put up?
(*) What is the
wattage (in W)
of each panel?
(*) How many
hours of "full sun"
(average) are received at the location daily?
Note: One "full sun" hour is equal to 1 kWh/m
^{2}
per day.

(Make sure all cells have a number in them!)
WIND TURBINES
Here are the 3 pieces of info, you must enter into the table:
(*) How
many
turbines are going to be put up?
(*) What is the
wattage (in kW)
of the turbine(s)?
(*) What is the
capacity factor (CF)
of the turbine(s) given the wind profiles at the location?
