MONEY & ENERGY
Energy consumption by the electricity generation industry increased
by 107% between 1977-78 and 1997-98, reflecting rapid growth in
some end use sectors in which electricity is a prime energy source
and it is the dominant source of greenhouse gas emissions, These
consumption are expected to grow by over 28 per cent by 2010.

In United States consumption of 16,782,744 GWh represents
1916 million kilowatts of electric power. At least 50% to
60% of the power is consumed by electric motors.
Taking into account 80% average efficiency of electric motors
and price $0.05/kWh, in 1995/1996 the United States paid $524.5
billion for running these motors [0.5
x 1916 million kW x 365 x 24 hrs x 100/80 x 0.05 $/kWh = $524.5
billion]
Since the AMM motors increase average efficiency to
84%, Annual Energy Saving is 499.4 billion kWh.
[0.5 x 1916 million kW x 365
x 24 hrs x (100/80 - 100/84) = 499.4 billion kWh].
Respectively, Annual Dollars Saving is $24.976 billion
[0.5 x 1916 million kW x 365 x 24 hrs
x (100/80 - 100/84) x 0.05 $/kWh = $24.976 billion].
Energy consumption increases and the Annual Dollars Saving
would be $31.969 billion in 2010.
The savings achievable practically with no costs, represent
4.76% of energy supplied to electric motors and 2.5% of total
electrical energy consumed in the United States.
Annual electricity losses in distribution systems represent
approximately
6 per cent of distributed energy and they are :
- 1,006,964 GWh in US
- 46,118 GWh in Australia,
- 113,283 GWh in United Kingdom.
Because energy losses are in a square with a transmitted
current, the AMM motors save 11% of currently disappeared
energy. This means that after using the AMM motors an additional
Annual Dollars Saving in 2010 would be :
- $US 7.1 billion in United States,
- $AUS 909 million in Australia
The energy distribution savings are automatic and with
no costs.
( The rules and calculations are equally
applicable to each country and currency.)

Below singular example relates to a small factory using motors'
power of 500 kilowatts installed in small motors. By replacing
them with the AMM motors, an average efficiency increases
from 75 to 79.5%, creating a power saving of 37.5 kW. Respective
annual saving results to :
- $ AUS 53,000 in Australia,
- DM 66,000 in Germany,
- $ US 27,000 in United States
Below examples show saving of energy in domestic refrigerators,
washing machines, vacuum cleaners, portable power tools, and
air conditioning systems. The examples relate to Germany,
Australia and US, however, they are equally applicable to
each Country and currency.
Germany
The AMM motor used in an average 560 Watts washing machine
saves 100 Watts. As the machine is working 5 to 6 hours per
week and price
1 kWh is 0.20 German Mark (DM), each machine saves 7 DM per
year.
In the case of 20 million German families the annual saving
is 135 million DM. When the AMM motors are used in refrigerators,
vacuum cleaners, and portable power tools the savings are
:
- refrigerators; 26.25 DM per unit and total of 525 million
DM,
- vacuum cleaners; 10.5 DM per year and total of 210 million
DM,
- portable power tools; 3.6 DM to 4.64 DM and total of 104
million DM.

|
The annual saving of 974 million
German Marks represents
555 Megawatts (MW) of electric power, giving 50 DM less
electricity bill for each family. The saving is equivalent to
2.4 million tones of greenhouse gases entering the environment
and represents power used by a city with a population of 3 million
people e.g. Berlin. |

|
|
Australia
After using the AMM motors in Australian domestic refrigerators;
washing machines; vacuum cleaners and power tools, the saving
is AUS $195 million. Taking into account replacement of standard
4 kilowatt motor that is used in typical air conditioning
domestic systems with the AMM motor and that the
system is used during 60 days by 10 hour, the annual saving
is AUS $50 per unit.
Since, 80% of Australian families are using the air conditioning
systems the saving is $AUS 158 million per year.
|
|
|
|
It means that after using
the AMM motor only in these small domestic applications the
annual saving is AUS $352 million and that each Australian
family annually pays AUS $70 less for its electricity bills.
The annual saving is equivalent to 250 MW power plant
and to
1 million tones of greenhouse gases entering the environment.
It represents electric power that is required by residents living
in South Australia and in Northern Territory. |

United States
In the United States with a population of 250 million the
saving related only to the domestic refrigerators, washing
machines and power tools, is $1.25 billion.
Since 70% of 60 million American families are using the air
conditioning systems, the additional saving is $848 million.
The annual saving of $US 2 billion (1.25 + 0.848) shows
that each American family pay $US 35 less for its electricity
bill.
|
|
|
|
The saving is equivalent to 3 thousand MW power plant,
to 12 million tones of greenhouse gases entering the environment
and it represents electric power that is required by a city
with a population of 19 million e.g. New York.
|
 |
|
|
|
|
|
|
|
|
Because costs of the AMM motors are on the same level as the currently
produced, the savings are with no costs.
