When it comes to energy resources, there aren't many places on Earth that can rival Australia in either abundance or variety ... coal, wind, waves, solar, nuclear, hydro, natural gas or biomass

Some critics describe Australia as the engine room of climate change, as we stoke the fires of global warming with coal exports and our own reliance on 'dirty' electricity production. Others more optimistically point to the ingenuity of Australian research in developing viable new technologies for harnessing cleaner, green alternatives, and even see us as having the potential to be leaders in the battle to contain climate change.

  Power to the People
Dr Barry Manor, Sustainability Consultant, looks at the state of play of renewable electricity generation in Australia and at the contribution that a fearless visionary like Elon Musk brings to the future of electricity. There is an enormous amount of activity in the renewable energy space in Australia at the moment. The biggest battery ever is now patched into the South Australian electricity grid to help stabilise it during an unforeseen event with the main saving is avoiding building another gas-peaking power station. There are still significant challenges in the development of renewable energy in Australia. We are stuck with the transmission grid because it cost a huge amount of money to put up that infrastructure, the big iron towers with all the struts and beams that support high voltage cables. This grid was designed to move energy from big centralised coal-burning power stations around the countryside. It was not designed to have a large number of smallish renewable generators connected into it at various points along the transmission lines, a two-way transfer of energy. A solar farm, for instance, has to find land that is close to the grid where it has the capacity to accept the energy created. In many cases solar farm owners must build their own grid connections at a cost of $1.2 million per kilometre of cable. The cost of electricity from a solar farm over its 25 year service life is 3-5 cents per kilowatt hour whereas we are paying 25-30c per kilowatt hour for fossil fuel-based energy. Investment certainty in renewable development is sorely lacking at a federal government level and there is concern is that after the early 2020s there will be no further incentives to develop renewable energy. We hear about loss of jobs in the coal industry but not the gain of jobs in the renewables energy sector. In another field, the global electric vehicle revolution has begun. Elon Musk from Tesla Motors has launched the Tesla truck, a full-sized heavy haulage truck with a range of 800 km on one charge. The truck can maintain 100 kilometres per hour up a pretty decent hill and when empty can accelerate from 0-11 kph in under 5 seconds. The total cost of ownership of this truck over its service life is 20% lower than a diesel one. Tesla vehicles (models S and X) are on the road right now. They are high performance vehicles which give petrol cars a run for their money but they do cost over $150,000 in Australia. The Model 3 is intended to cost around US$30,000 which is comparable to family-oriented cars. This model has had 400,000 pre-orders before it went into production, an amazing level of consumer confidence. Tesla has also showcased the Roadster 2 an incredible piece of engineering rumoured to cost around $250,000. It can accelerate from 0-100 kph in 1.9 seconds, faster than anything else on this planet! In the future renewable electricity generation really will bring power to the people.

  Powering up battery energy storage
Australia is in the process of a complete energy market transformation and people are thinking big to solve problems. It seems we are well on the way to forming a new power base in this country. A whole suite of technology is emerging to support that shift and economics is supporting that transformation too. Batteries have evolved enormously in the last few years, having changed their chemistry. Lithium battery will be the predominate battery for the next decade and it is predicted they will drop by 40% from their present price of $10-12,000. There are huge investments in building factories that make lithium batteries.Tesla Corporation has reached an agreement with South Australia to build the world`s largest storage battery in conjunction with a French company (Neoen) that builds wind farms (the Tesla battery will be sited at a wind farm connected to the grid). Elon Musk has promised that if the battery is not built in 100 days then it will be free. The battery will have a supply capacity of 100 megawatts (more than double the present largest battery installation) and be able to store 129 megawatt-hours of energy. It will provide load balancing for renewable energy generation in SA and allow emergency back-up power if a shortfall in energy production is predicted. A Brisbane company, the Lyon Group, already has proposals to build even bigger batteries in South Australia. Commercial-scale batteries use a modular approach and are often housed in shipping containers that are readily available all around the world (since they are uneconomical to ship back to China).

  Power politics and the SA Black System in 2016
Dr Barry Manor, Sustainability Consultant, explains how the black system occurred in South Australia, creating a loss of electricity for the whole state. On the 28th September 2016, amid a period of high winds, lashing rain and thousands of lightning strikes right across the state, the South Australian electricity grid suffered what is known as a black system. This happens when an entire grid goes down to zero volts, completely losing all electricity. 

  Practical power policies not politics please
Who determines the cost to the community of power? What are the reasons for the major costs? How often are these assessed? Who are the regulators? Who regulates the regulators?  What is their expertise? What is spot pricing of our electricity on the eastern grid? Why does it operate more like the stock exchange than an integral part of an essential service heavily subsidised by Australian taxpayers? Questions like these and MORE for all our political parties that need answers and not finger pointing. Practical power policies not politics please .... perhaps please explain ... What price power and why?

  Switched on solar research
Australian research and development has achieved such outstanding improvements in photovoltaics that now hold the world record of 40% efficiency for converting sunlight to electricity. The next step is already underway towards demonstrating viable, economically competitive local and international solar power plants.

  Some good news for renewables
Some good news for renewables
New Energy Levels: Mark Bretherton, from the Clean Energy Council, explains the role of this peak renewable energy organisation and the role of other organisations and factors in Australia’s renewable energy sector. The last few years have been challenging for the renewable energy sector when the federal government decided to review the Renewal Energy Target (RET) at the beginning of 2014. The RET is the most important policy for the renewable energy industry, encouraging the lowest cost types of renewables to be built. The uncertainty created by that review meant that financiers were reluctant to lend the money required, investments dropping by 90% for large scale renewables like wind farms and solar farms. The 13 projects that were underway in 2013 slowed to a trickle, with only a couple of projects still underway. The 18 months of chronic uncertainty were ended when bipartisan support for a lower target was achieved.
