                                                       EFFICIENCIES IN ELECTRICITY DRIVEN ECONOMY

We have lived on this planet for nearly a century with the concept that electricity is the ultimate solution and it was .
It is convenient to use and easy to distribute .Electric wires can carry energy for very long distances and at the lowest possible cost

but since then we have added some other sources of energy supply through piping and cabling  .
Gas pipes - telephone lines - fresh water pipes  - flushing sea water - sewage pipes .

0) POWER PLANT (burning gas or coal ) ===>   electricity  =  approx 35  (normal plants)  to 50 (with co generation)  % efficiency ..
Efficiency is the difference between the energetic power of the primary source (gas) and the potential energy available produced after transformation  .

00) If we calculate from the extraction site (gas or coal ) adding the cost of treatment ,conditioning ,transportation ,storage .
The efficiency drops from 35-50 % to approx
10 % .( Just to liquefy natural gas it takes 30% of the energy that the gas contains) .                                                                    
                                                                                                                                                       

1)  Any electrical Motor ( drilling machine - fan - electric car -compressor ): approx
40 to 50 % efficiency .
2)  Device using electrical resistor to produce heat : oven ,water heater , rice cooker : approx
50 to 70 % efficiency .
3)  Device using electrical resistor to produce light (lamp ,light bulb )    : approx  
 10 % efficiency .
4)  Device using compressed gas to produce positive or negative calories (heat exchanger  inside an air conditioner or fridge )  about
30 to 50 % efficiency .     

We have therefore an average of efficiency
starting from a power plant
:

0 + 1       =   
19 %    for a motor
0 + 2       =   
25 %    for a heater
0 + 3       =     
4 %    for a light
0 + 1 + 4 =     
8 %    for an air con


PARALLEL :   price of energy from extraction to consumer  goes from 0.3 US$ for 1MMBTU   to 13 US$ of equivalent electric .(45 times )
                      in the same times we have lost on the way  95 to 99 % of the needed energy
Renewable energies             Wave energy                              Wind energy                                              Solar energy
and an average of efficiency
starting from the extraction source

00 + 0 + 1            =   5 %    for a motor
00 + 0 + 2            =   
6 %    for a heater
00 + 0 + 3              =   1 %    for a light
00 + 0 + 1 + 4        =   2 %    for an air con

Natural gas  CH4  has a 100 times more green house gas effect than CO2
