What is a ‘solar garden’ and why we should want one

I put solar panels on my roof soon after I built this house because I was trying to plan for my retirement. That makes me one of the lucky ones, but what about those who are renting? Or simply can’t afford to put solar panels on their roofs?

Given the soaring cost of energy, this article by Citizen Mum, an Aussie blogger, really hit the nail on the head:

‘The concept of a solar garden is new in Australia, and is being developed by Pingala, a citizen led co-operative focused on developing people-centred and socially just energy solutions. At its core the concept is very simple and based along the lines of a community garden, in that cooperative members have the opportunity to purchase plots (panels) in the solar garden and have the energy that is generated from the plot credited to their power bill. It is ideal for people in rental accommodation, apartments or homes that are not suitable for rooftop solar.’

To give a little context to that quote, Citizen Mum is talking about ‘mid-scale solar arrays’. These are like the solar panels we’re used to seeing when we see photos of solar farms – fields and fields of solar panels almost as far as the eye can see:

Yeah, like those but smaller, much, much smaller. Mid scale solar arrays are big enough to provide a decent amount of solar energy, but small enough to be ‘owned’ by a small town. Or as the quote suggests, owned by the individuals of that town.

If you’re interested in mitigating climate change, and perhaps saving yourselves some money long term, I strongly suggest you read the whole article on Citizen Mum’s blog.

Climate change & Australia’s National Security

Australia’s current Federal government has been flogging the dead horse of ‘national security’ for a long time now, yet when it comes to Climate Change, they’re incapable of seeing the potential for true national security impacts.

What impacts?

Answer: the refugee crisis looming amongst low-lying pacific nations.

As sea levels rise, many of these small, island nations will either cease to exist altogether, or they will lose so much land mass that their populations will be squeezed past tolerable levels. One of the first to go will be Tuvalu:

As the largest, and emptiest land mass in the region, Australia will have to take responsibility for its share of displaced people. These Refugees won’t be from the other side of the world, they’ll be on our doorstep, and we will have a moral obligation to help.

In the Innerscape trilogy, I forecast that Australia would accept its responsibilities in the region, albeit grudgingly. The way things are going, however, I’m no longer sure we will. But what if we don’t?

If Australia’s government continues denying the impacts of Climate Change, we’re going to be caught without a paddle when reality proves the deniers wrong. There will be refugees, and if we refuse to accept them, our poorer neighbours will not be able to cope. That’s when they will look at our large landmass and tiny population and say “this isn’t right”, “they shouldn’t be allowed to shirk their duty”, “they’re letting us suffer while they live selfish, greedy lives”.

Guess what happens then?

Haven’t we, and our Western allies invaded other countries for similar, ‘humanitarian’ reasons?

For a more detailed analysis of the impacts, please read the article by Chris Barrie on the Conversation Room[Chris Barrie is Honorary Professor, Strategic and Defence Studies Centre, Australian National University]

We have to stop thinking of Climate Change as a ‘choice’. It isn’t. We’re going to be hit from all sides in the not-so-distant future, and only a concerted, united effort with our neighbours will save us.

If the military can see that Climate Change is a problem for national security, why can’t the Liberal National Party?

Generating power at night, the flip side to solar

Nuclear energy has been in the news lately, and its proponents have once again cited the intermittent nature of renewables as a compelling reason to embrace nuclear. They say that only nuclear can wean us off fossil fuels fast enough given the imminent climate crisis.

My argument has always been that renewable technology is still in its infancy and that the sector will explode with new tech in the near future. This post is about one such possible ‘new tech’ – thermoelectric generation.

I can’t explain the science, but I can say that this new direction in power generation would work at night, while solar is unavailable. You can read the complete article here:

The amount of power generated was miniscule, but this experiment sought only to prove that the principle was sound. Scaling up the process and making it robust enough for commercial applications will take a while, but then so does setting up a nuclear power plant.

My money’s on the new tech rather than the old.
