Slide5 l.jpg

The Engineer’s View

Supply Management

Generate more electricity by increasing production or improving efficiency of conventional technology.


Slide6 l.jpg

The Economist’s View

Demand Management

Reduced Demand

By

Increasing Price


Slide7 l.jpg

Are these the only ways?

Are we forgetting something?


Slide8 l.jpg

What we are forgetting is that all the forms of energy are not equal or alike.

Some forms of energy may be better suited to be directly applied to demands rather than through conversion to and expenditure of electricity.

Matching appropriate energy supply to end use is the answer.


Slide9 l.jpg

Broadening Our Perspective not equal or alike.

Why is it that we only think of electricity when considering Energy?

Energy = Exergy + Anergy

Electricity is the highest form of energy; it is Exergy itself.

Practically, due to imperfect efficiency, electricity usage leads to both Exergy and Anergy.


Slide10 l.jpg

Are we forgetting something again not equal or alike. ?

?

Consumers don't demand energy, they demand goods and services.

Electricity is not an end in itself. It is only ONE of the means of ensuring delivery of these needs.


Slide11 l.jpg

The other ways… not equal or alike.

There are various other forms of energy available to our disposal such as solar, wind, hydel, tidal, diurnal differentials

Conventional wisdom is to use these renewable forms to generate electricity.

Slide14 l.jpg

The 'Energy Crisis' does not stem from a lack of energy… not equal or alike.

…but from a failure to match forms of energy to the real requirements of the consumer

Amory Lovins


Slide15 l.jpg

The Softpath Approach not equal or alike. Proposed by Amory Lovins

A soft energy path is one that is pliable, one that matches the energy source to the energy demand.

There is no demand for electricity, oil or Uranium. The demand is for needs and comforts.

The soft path approach is about supplying the most appropriate energy in the most energy efficient way to meet those needs directly.


Slide16 l.jpg

Features of Soft-energy Paths not equal or alike. Proposed by Amory Lovins

  • - Rely upon natural energy flows

  • - Are diverse, thus not over-dependent upon any one source

  • - Are flexible using local resources and materials

  • - Are matched in scale to end use needs

  • - Are in harmony with environment aligning with nature rather than controlling it

  • - Are matched in energy type and quality to end use needs

  • - Are resilient


Slide17 l.jpg

Practical applications for not equal or alike. building designs in the Middle East

Indoor illumination and water heating using solar insolation.

Natural ventilation using wind energy to ensure healthy indoor air quality.

Temperature control and cooling using diurnal variation of humidity, temperature and wind conditions.


Slide18 l.jpg

To sum it up… not equal or alike.

Think beyond electric/grid power. There’s more to energy than electricity.

High Exergy solutions may be the most convenient but are not the most optimum and sustainable.

Matching appropriate forms of energy directly with needs can yield significant efficiency gains.

The environment is your ally. Work with it rather than against it!


Slide19 l.jpg

We must remember that … not equal or alike.

‘There is no free lunch’

let us try that our future generations do not have to pay for our mistakes.

Elegant and Sustainble Solutions are at the "Bottom Of Exergy Pyramid"

Promising Sustainability with Harmony and Quality of Life

Thank You! not equal or alike. Questions?
