The United States has achieved a 25Megawatt of wind generated power...but what does that mean?
Is that a day...an hour...a week or month...even a year? Well when we talk about power generation we are talking about an hourly output, So when we say that we generate 25-Megawatts we mean that we have an average hourly output of that level ... averaged over the year...which accounts for high and low speed revolutions on the wind generators.
Now with that aside...what is a Watt? Simply stated in basic electrical terms a Watt is the energy needed to do work...and it is the result of Volts generated multiplied by the current flow reported in Amphere hours (or amps). If we are generating 25-Megawatts we have 113636.36 Amps at 220 average volts.
Well, we are getting closer...but is there a visual we can create? Yes...lets talk light bulbs...say 100 Watt incandescent light bulbs... if you have 25,000,000 watts and we devide it by 100 we would find out just howmany bulbs we could illuminate with this power source...
So 25000000/100 equals 250000 light bulbs glowing brightly...
Electricity consumption by 107 million U.S. households in 2001 totaled 1,140 billion kWh so you can see that 25Megawatts is not that powerful a source...
