Solar Energy – The Oldest Power On Earth

Years of Power In Just One Day

There is more solar energy striking the earth’s surface in one and a half hours (480 EJ) than worldwide energy consumption in the year from all sources combined (430 EJ).solar-power-cut

“The question I ask myself is: what do I want to achieve? and what are all my options to get the task done? For example: when I buy a drill I am really wanting something to make a hole. Essentially, we need to

Wide Spectrum of Solar Opportunities

Solar power is abundant, free and the oldest power source known to humanity. The Sun beams a broad variety of energy waves to us.  For thousands of years humanity has used the heat, light and UV for our daily tasks.  We are enjoying an explosion of research and development as we near peak pollution and warming targets.  Along with the rise in Solar technology a number of female engineers are leading research and many mature women are able to contribute to installation and maintenance.

What is the Environmental Cost of Solar Panels?

To calculate the full cost of any gadget we can do a whole of life analysis. This works out the energy cost from the time we dig the materials up to the time we dispose or recycle the materials. Research shows that a solar panels generate more energy that it took to create and many panels are lasting much longer than originally expected.

With recent developments including organic solar cells, the environmental cost is coming down. Durability and effeciency is constantly rising.

Can I Use Solar Energy Without Buying More Stuff?

Some great passive solar options include:

sustainability workshop
  • attach a conservatory or Greenhouse (made with recycled windows) to the sun-side of your home to create warm air. the trick is to keep it small to reduce the cooling air movement.
  • place mirrors in the garden to reflect light into the home. You can make sculptures out of recycled stainless steel instead of glass.
  • create a solar oven made out of reclaimed picture frames and a thickwalled box.
  • make your own light-shelves, install a waterbottle light in a dark shed
  • experiment with drying food
  • incorporate simple heat banks [like Trombe walls] into your home and office
  • hang herbs to dry in your kitchen or a simple solar dryer
  • hang your clothes to dry
  • if you live in a cold climate – build a cozy outdoor nook in the sunny corner of a tiny greenhouse. Incorporate lots of thermal mass (ie. mud-brick benches and pillars) and you can sunbathe in it on sunny days in winter.  Install a shower with a rocketstove water heater in another corner and you could spend most of your winters daytime happily in there as do many on Carraig Dulra permaculture farm in Ireland!

Here is a great list of DIY projects – Enjoy!

Is Chicken Threatened by Climate Change?

The Chicken Companion

chick_eggThe Chicken is one of the most successful species on the planet.  The chicken has traveled the world, exhibited in shows and been pampered affectionately.  For centuries they have enjoyed the best seats, fully catered free rides on ships, planes, trains, buses, canoes and rafts. Contrary to recent reports, Chickens are likely to adapt faster to climate change than humans. They have adapted twice already during their companionship with humanity. They are set to stay.

Chickens Process Waste and Provide Perfect Protein

Over Ten Thousand years ago, the chicken became the first domesticated animal.  What attracted the chicken to people was the abundance of waste. Chickens don’t mind eating slightly off-meat and love maggots and other distasteful horrors. Chickens rarely compete with humans for food. They eat a wide range of food and grit. People probably decided to keep the persistent chickens because they are relatively easy to catch at night and have highly nutritious eggs. They would have seen how quick and efficient chickens are to clean the waste.

What do Chickens have that we don’t?

Chickens often have carers. Chickens are also opportunistic eaters and learn to adapt to dietary changes. They are persistent parents. In good conditions they will breed every year. The chicks learn quickly and are independent within a few short months. Quite often, if things go poorly in the mothering house, a chicken will simply take a short break, fraternise with her favourite rooster then start laying and sitting again. Each generation provides a chance to genetically adapt. Even old hens [ie. our 9-year-old chicken, ‘Ginger’] suddenly started laying again if the conditions are right.

Chickens wake up with purpose and sleep well.

Chickens have been bred to be docile. Many domestic animals can die from stupidity. Chickens are highly unlikely to cause themselves harm.  Chickens have been known to accidentally drown or get trapped. Nor are Chickens so gallant that they choose to die. However, Roosters have been known to nobly defend the flock.

Fast Movers

Chickens come originally from the dense forests of the Tropics. Scientific evidence has demonstrated that they have already adapted twice before to enable them to grow obese anchickens-weedingd to breed all year round. They can adapt again, if they are given the r. Dr Carl-Johan Rubin of Uppsala University. 

When we provide chickens with the chance to shelter in the cool sections of a food forest, they help to control the weeds, fertilise the trees and clean up fallen fruit. Their tendency to get fat makes it easy for us to catch them when we need to.

Creative Chickens Train Their Keepers

It is us, the keepers that need to adapt if we wish to continue enjoying the company of Chickens. We can devise solar passive chicken houses, give the chickens some self-determination about where to lay or hang out during the day and take time out to observe them.

Anxiety and Permaculture? What’s the link?

Anxiety – Not A Merry Culture

sad-elephant-in-the-roomPermaculture (the design for a permanent culture) has the core ethics of care of people and care of the earth.  These two ethics seek to redress social and environmental ills.

Dr Terry Leahy sees clearly the link between anxiety and permaculture. Terry is presenting at our upcoming mini-conference about Permaculture in Society and Development.

Terry Leahy writes: How can it be good that one in four Australians experiences serious attacks of anxiety at one time or another in their lives? In any twelve month period 14 per cent will get anxiety attacks.

What is there to be Anxious about?

What is there to be anxious about when we live in the lucky country, surrounded by mod cons and ever-increasing wealth? The environmental catastrophe that everyone knows we are in for but nobody talks about too often. Work and economic survival in the neo-liberal economy.

have a giving spirit

Once upon a time jobs were for life if you wanted that, and there was full employment. House prices were low and government supplemented the housing market by building low-cost rental accommodation. Now a huge proportion of the population in work are doing casual jobs rather than having permanent positions. Those who are in permanent work are scared that it cannot last. House prices are crazy and there is no security in renting. Unemployment seems minor at six per cent but most people who cannot get a job do not register as unemployed, it is so hard to stay on welfare.

Add to all that the sense that the recession of 2008 has never gone away and the realization that the Australian economy still hangs on a knife-edge. People are made constantly aware that their life security depends on constantly jumping through hoops and being ready for anything.

We need an economy where people’s daily well-being does not depend on the vagaries of the global market, where the environment has priority and where you can really expect your grandchildren to live as well as you have.”

Self-Reliance versus Self-Sufficiency

bushwalk

Self-Sufficiency is rare. It has the goal of complete independence from society. In the self-sufficient culture, the sick or elderly are often left to die. Self-Reliance is different. Self reliance is a way of thinking and living that enables others to be part of the responsibility of providing for our needs by trading and sharing. The ‘Self-Reliance’ economy would involve care for the weak. Permaculture promotes self-reliance.

Keeping the Power of Feelingswe-can-do-it

When we are faced with anxieties it is hard to maintain optimism. Yet “optimism has more power than fear” (Bob Brown). Optimism is patient, organised and forgiving. Whereas, Fear is reactive, quick and often unplanned, leading to panic and regret .

The Great Eco-Tech Divide

You can’t always get what you want!

What an amazing era of technology we live in! Super efficient technologies pop up daily. But when the average earth-user reaches out to adopt them, there’s no-one there to guide them.  It’s tough and expensive to yearn for new technologies. The pioneers have to be prepared to take an active role in implementing new technologies and providing constructive feedback.

A key permaculture principles is: Information and observation replaces energy use. The more we learn and observe, the less effort we will need to spend getting it to work.

Retro-fit nightmares

Are your thinking about adopting a new technology? Maybe it is solar air-conditioning. This is a great recent science invention based on adsorption (not absorption). Or perhaps you want to convert your conventional toilets to a compost system. Well, how do you go about it? who can advise you independent of the sales people of a particular brand or particular technology or method?

There are lots of teething problems and pitfalls in the commercialisation of the eco-technologies.  Consumers risk failing with the business that strives to help them. When we recognise the pitfalls for the businesses, we can assess them better and help them and others.

Each Eco-technology manufacturer needs to build their:

  1. supply chain security with distribution methods
  2. support network for parts
  3. expert after-sales service
  4. methods to listen and learn from user feedback
  5. installers – trained installers
  6. demonstration sites where people can touch and feel the gear before committing

Brave Pioneers

Info-replaces-EnergyThe early adopters of new technologies pay a lot of money for products that are usually only just at the adequately functional stage.
These consumers often have to

  1. write their own ‘operations manual’ and
  2. source after sales parts and
  3. make modifications or improvements are at their own risk
  4. be able to service the equipment themselves

At Permaculture Visions we were the first people in our region to set up a solar-hot-water radiator heating system. We took temperature measurements for 12 months to help provide feedback to the supplier and write our own user-guide. With some self-maintenance it is still working well.  Sadly the provider, along with many local manufacturing companies, has closed down.

Speeding up the Eco-technology uptake

Eco-technology uptake can be sped up on three levels: government, business and grass-roots.  Greater government leadership can:

  • provide regulating authorities who provide advise on national and international standards
  • listen to independent forward-thinking councils such as Clean Energy Australia,
  • support regional demonstration institutions such as Future world
  • limited and targeted subsidies can make big impacts.
Clean Energy Council Australia

Business can bridge the gap

There is a gnawing gap between displays of new technology (crowing about it) and honest appraisal and evaluation. The consumer has to know their own needs and be able to assess whether the new technology is appropriate.

If you have a head for technology, are people savvy and don’t have an investment (financial or emotional) in any particular type of technology, here is a good business opportunity for you. You could advise people on which technology would suit their needs best. You could set yourself up as an aggregator. There are some aggregators for individual technologies ie. solar but there are no aggregators for a range of eco-technologies. This can be done as a consultant or in software format.

Business and institutions need to SHOW,  EVALUATE, INFORM, SOURCE improvements and MAKE COMPARISONS.

Choices on the domestic front

Whenever we make a purchase, we are making a technological decision. If we choose an old technology, we might feel we are playing it safe – but are we really safe? When we reach out for an older, proven technology our choice has two impacts.

  1. It supports the current way of life that is not sustainable and governments are already acting to limit this technology.
  2. It fails to support technological advances unless there is a real improvement on the old technology.

The safest option is to adopt a mixture of safe and new technologies to serve our need. This is like wearing ‘a belt and braces’ to be sure the pants stay up.  Consider first the soft technology options. There are a lot of natural and traditional technologies that cost very little to set up (eg. planting deciduous trees on the sun-side to cool the house in summer, using double glazing to hold heat and allow natural light).

Tailor and Blend your technologies

Optimise your soft-technologies like permaculture and dabble intelligently in the cutting-edge eco-technology to build a path to a healthier future.
