Energy prices on the rise

 Its no secret that lately, the cost of energy has been on the rise. Regardless of where you are its gone up, and guess what; its going to go up alot more in the next few years.
 So, to help, I figured a good first post would be how to determine what any energy costs will be 'before' you purchase gear, or make changes to you existing setup. Ive included the formula as well as some costs for
common watt systems in both LED, CFL and HID watt ranges.
Before we get started I need to make it very clear, not to buy LED setups without doing some research, the
technology is not the same as CFL or HID; nor is it setup and calculated in the same way.

  First, the formula.
Find and add up all the wattages for everything you have running, not just the lights.
Lights, Fans, AC, heating mats, vents, radios "for the true hippie" etc.
Add them together, and place them in the formula as W.
kWh = your cost per kWh

( W / 1000 ) * kWh = Cost to run per hour

From this you can do         Result * Hours = Cost per day
and then of course take that result and multiply it by the number of days in a given month to find the cost
for that month.
SOOOO lets do an example, why not ha!

Fan = 25w
Light will be a 600 watt HID "type does not matter, it uses 600 watts"
625watt grow room

Lets say for this example, its 9 cents for kWh  " $ 0.09 "

(625 / 1000) * 0.09
.625 * .09
.05625  "Round this to cents .06"
$0.06 / Hour

Not bad right :) 9 cents is a dream though, most people play 15 cents, and ive heard of people paying 40!

Moving on
at 6 cents per hour thats $1.08 for an 18 hour day, costing you $32.40 for the month "30 day month of course".


Here are some "flat line" results based on numbers from hydro costs in my area.


Wattage                      || KWH      || Hourly      ||    Daily     ||  Monthly
--------------------------------------------------------------------------------------------
90 Watt                      ||  .10          || .01           ||  .17          ||   4.86
90 Watt                      ||  .12          || .01           ||  .19          ||   5.85
180 Watt                    ||  .10          || .02           ||  .33          ||   9.72
180 Watt                    ||  .12          || .02           ||  .39          || 11.65
250 Watt                    ||  .10          || .03           || .45           || 13.50
250 Watt                    ||  .12          || .03           || .54           || 16.20
400 Watt                    ||  .10          || .04           || .72           || 21.60
400 Watt                    ||  .12          || .05           || .87           || 25.92
600 Watt                    ||  .10          || .06           || 1.08         || 32.40
600 Watt                    ||  .12          || .07           || 1.30         || 38.88

Based on 18 hour days, 30 day months.



I was going to do fans etc, but i cant do all your homework :D
