Energy Consumption Growth

By Garry Baverstock AM, Director of Wise Earth P/L

Introduction: Energy Consumption Growth

In 2005 World President of ISES Professor Yogi Goswami of USF in Florida, made a keynote speech at the ISES Solar World Congress in Beijing. There he predicted that most of the world’s uranium, gas, oil and much of the world’s coal depleted.

At many of my talks in Australia and overseas since and in private discussion with fossil fuel, and uranium experts I noticed that I have either been looked at as have ‘two heads’, or the ‘specialists’ simply disagree, but offer absolutely no factual back up for their opinions. I have had the impression that it is yet another instance of an ‘inconvenient truth’ as exposed by Al Gore, or just plain ignorance that gets no response of any worth to anyone except their feelings of security.

This article squarely presents the latest information from the USA that clearly states Goswami and I, by my re-quoting his 2007 facts, have been perfectly correct. Having experts around the world that there is not an issue with population growth, energy consumption and supplies, and worse still denying the climate change effects that are so evident all around the world, with record breaking extreme weather events on the increase. The reasons why are governments moving so slowly and so divisively are complex ad are more to do with human psyche, primordial subconscious desires, rather than facts and data.

Who should we blame for such collective insanity? Surely this places the climate skeptics and ‘anti-sustainability types’ as anti-humanity forces not just an annoying or inconvenient impediment of change, as currently and often portrayed in the media.

It is a simple question but a very complicated answer that will take more resources that I can offer as part of this article.

Suffice is to say that in my opinion, all us thinking citizens of the world need to have a good look at ourselves and our integrity and start to take more affirmative action to move to sustainable energy world as soon as possible and solve ‘Climate Change’ once and for all and save humanity as we know it at present.

Defense and Security Issues

The following information has been researched and supplied by Peter Kasprzak and indicates dire consequences for the world beyond 2050. So indeed Yogi Goswami was correct after all as well as my placing this issue in context of what we should be doing with the built environment.

U.S. defense and intelligence communities are increasingly focusing resources on the operational and national security implications of climate change and energy. With the most recent quadrennial report identifying climate change as a global destabilizing force for the first time, an executive order from President Obama on sustainability across the Federal agencies, and an uncertain and unstable energy market, the challenges before American defense and national security communities to mitigate climate impacts and energy risks, as well as establish a leaner, more effective operational force in a down economy are clear.

According to the U.S. Energy Information Administration world energy demand will grow by half in less than 25 years.

The world consumes 500 quadrillion BTU today, but it will need 750 quadrillion BTU by 2035. (BTU or British Thermal Unit is the heat that will raise the temperature of one pound of water by one degree Fahrenheit. One BTU = 1054 joules = 0.000 293 kWh and 1000 BTU per hour = 0.293 kW)

This would seem on the face of it to be a bonanza. When I have brought up the consequences on world population levels I have been accused by some ‘sustainability’ experts as being somehow racist. In fact I am being very reasonable. Instead of short term cashing in on demand for energy and encouraging population growth in the world, I believe we should restricting growth, and if anything working out humane methods of gradually reducing it.

Why? Well have at look at the following predictions for population growth towards the end of the century based on energy supplies. Do you think we have a crisis looming? The predictions are alarming and the security and stability of the world will be in tatters.

Population Growth

Also take a look at the World Energy and Population – Trends to 2100 study, which asserts that world population, and therefore energy usage will dramatically decrease in the second half of the 21st century.

This time instead of BTU the energy is expressed in Mtoe (Millions Tons of Oil Equivalent), 1 Mtoe = 39652608749183 BTU

Here is the alarming prediction for world population that we need to take into account very seriously indeed.

Why are we continuing to encourage population growth to ”grow” our economy? It is nonsensical. I have heard predictions that the world population will reach 9 billion. How is that going to happen? Is it the wish of the ‘business as usual’ pundits who make millions out of increased consumption of raw materials, carving up land for housing estates built by large project building companies.

What sort of a world are we leaving for our children and grand children?

It is clear to me that business as usual is leading this world clearly to a hellish existence. Is it too late to wake up? A rational thinker would have to say the odds of creating a peaceful sustainable and ecological stable world for our children and grandchildren is not looking good!

If I ever doubted myself for over the last 40 years of pushing ecologically sustainable development and maximum use of solar energy in the built environment to help create a solar economy, then those doubts are now completely evaporated.

In summary, please expect a lot more from me, my allies, ‘converts’ colleagues and www.solar-e.com and my company Wise Earth P/L. I hope you can do the same or join us as we push forward and try to adapt and change, as we will need to within one generation! This includes being solid mentors for the next generation so they can be far more effective in their lifetime.

Passive Solar Homes Design Creates 300,000 New Jobs

Designs of passive solar homes, incorporating advances in recycling building materials from demolition, water and waste water design should be the focus of progress in our search for answers to reduce our domestic energy consumption.  New advances in solar water heating, grid connected photovoltaic systems and the integration of other renewable energy systems should be incorporated  into the built environment.

Passive Solar Homes to Create Opportunities

Passive Solar Homes with Solar Umbrella

Passive solar homes, adapted to become energy and water efficient such as this house shown with a solar umbrella, could create 300,000 new jobs in the building industry – this growth would take place over 20 years and be in key industry areas.

The growth in new jobs will only take place if we are serious about reducing greenhouse gas emissions and introducing policies and practices to ensure we only construct and reconstruct energy and water efficient homes.

Australia’s built environment constitutes 33 per cent of greenhouse gas emissions and this figure increases to 40 per cent when infrastructure and embodied energy are taken into account.

These amounts could  be reduced if energy consumed in existing homes is reduced by between 30 and 50 per cent and by 80 per cent in all new homes. This is why passive solar homes are the only realistic solution to our residential built environment energy problems.  However not all designers and architects specialise in energy efficient design and a ‘near enough is good enough’ attitude will not bring the best results in reducing energy consumption. Contact passive solar homes specialists for the best advice and outcome and ask them for proof of their expertise before you enter any contracts.

Retro-Fitting Existing Homes

Of the 7.5 million houses in Australia we know most need to be retrofitted to become more  energy and water efficient. Many of these will eventually need to be replaced with new state-of-the-art passive solar homes because it will be too costly to retrofit them.

Homes to be demolished will have to be carefully recycled and this will entail the introduction of procedures and policies to ensure wastage is kept to a minimum.

Building Codes Needed For Recycling Existing Homes

National building codes and other relevant legislation in Australia do not require home owners and builders to comply with energy and water efficiency principles when demolishing, retrofitting or renovating homes.
Legislation is lagging and up until now lay people and industry groups have led the way in the instigation of innovative and necessary change.

The idea of adapting a home to become more energy and water efficient is normally decided by home owners, who place pressure on designers and builders to trial new methods.

Once these techniques have been found to be effective, builders adopt them into mainstream practice and political parties follow by introducing them into legislation.

This means the general public and industry professionals will continue to lead the way in the push for important change, but this may not be enough if we are to significantly reduce greenhouse gas emissions to mitigate the impact of climate change.

Demand For Passive Solar Homes

Many people in Australia want to live in passive solar homes and work in buildings that have been designed and built to comply with energy efficient and climate sensible principles.

While it’s good news people that people  want to live in energy efficient homes, there are barriers to these lifestyle changes which include money, industry know-how and legislative amendments. This is because the cost to retrofit a property may initially be outside a home owner’s budget despite the investment eventually being offset in energy savings while also reducing each of the occupants’ carbon footprints.

Legislation Lags Consumer Demands

Industry know-how and current legislation are also not at the level desired by consumers.   In the interim, young people, tradespeople, homes designers and architects could extend their skills’ levels by enrolling in sustainability courses  and placing pressure on landlords and employers to implement climate sensible and energy efficient principles in the rental market and the workplace.

However retrofitting and building new passive solar homes by home owners is probably the most likely and definitely the most effective response to our domestic over-consumption of energy.

Climate Change Solutions need adaptive management

Climate change solutions desperately need bipartisan political will and the input from the right collaborative experts, led by highly competent project managers – in order to deliver the outcomes needed in a specific time frame.

A multi disciplinary  systems thinking approach is needed

This will require an adaptive management method and a multi-disciplinary approach, just as  that applied by Gene Krantz from NASA when his astronauts’ lives were threatened by mishaps, during the Apollo missions –  Apollo 13 being the most dramatic.
Space ship earth’ needs people who are going to apply systems thinking to a total system overview.

Sustainable energy re-building Queensland.

The floods in Queensland have brought tragedy for some, and heartache and disruption for many, but can also bring opportunity for renewal for all, says the Sustainable Energy Association of Australia (SEA).

‘While towns and communities will have lost much, they will also have the opportunity to rebuild,’ says Prof. Ray Wills, SEA Chief Executive, and Adjunct Professor with The University of Western Australia.
