The Tesla Model S And The Powerwall (Image: Tesla)

This Little Known Tesla Innovation Is A Game Changer

No the game changer is not the 2015 Tesla Model S in the picture above. It’s the white device shaped like a medieval-shield that is blending into the wall behind it. It is a wall-mounted lithium-ion home battery system designed to store energy from rooftop solar panels. It can hold up to 10 kilowatt-hours of energy, enough to power a typical home for about 10 hours. It would enable homes to be powered by solar energy during the day and by battery during the night time.

It’s called Powerwall, and in 5 years it could be a major cash cow for Tesla

When Powerwall was released in April this year, it received largely negative press. The press assessed that Powerwall at the current price point was uneconomic for the average user, who gets fairly cheap electricity from the grid. Tesla took the negative feedback to heart and came back in June with double the specs with no change in the price. In doing this, Tesla raised the bar on price competitiveness in battery storage marketplace to a whole another level.

Correct as the original assessment by the press may have been, it was incomplete. The economics associated with Powerwall may look entirely different in 5 years time than it does today, making it a game changer for Tesla. 3 mega-trends are shaking up how we consume energy today –

Fracking changes the economics of oil production

The ‘fracking revolution’ has transformed the economics of oil production globally, with the US becoming a bigger producer than Saudi Arabia and – after decades of dependency on oil imports – even being able to export some of its surplus production.

US shale oil is unusual, too, in being privately owned: most of the world’s oil reserves (over 70 percent) are in state hands. Like the North Sea 30 years ago, in a world dominated by state-owned companies and publicly owned reserves, US shale could look like a new frontier for private operators on the search for fat profits.

New technology, high oil prices, and plentiful cheap credit have encouraged the boom. Some $200bn has been borrowed to invest in fracking in the last few years, accounting for 15 percent of the entire $1.3tr US junk bond market. Investors were, in effect, betting on continuing high oil prices making their investments profitable for years to come.

Price Slump

Last year’s slump in prices trashed that calculation. From a mid-year high of $115 per barrel, by the end of 2014 the price per barrel had fallen by more than 40 percent. More than half of US shale rigs have been laid up since October.

The driver, last year, was the behaviour of OPEC – the Organization of Petroleum Exporting Countries. OPEC is a cartel agreement among major oil producers that seeks to manage the international market for oil. With oil prices already plunging over the summer, OPEC could be expected to ease off on production. Restricting supplies should, thanks to the magic of the market, produce a decent increase in the sale price of oil. Instead, with Saudi Arabia taking the lead, OPEC decided to continue production levels. No agreement on restricting output could be reached. Prices slumped.

The economics of oil production are simple – crude, even. The upfront investment needed to sink a new well is significant. After that point, however, the variable costs – including pay – are a minimal part of the expenditure. That’s the case even when, as in Norway, oil workers’ average annual wages are $179,000.

These high initial costs, relative to lower running costs, mean that once a well is drilled the owner has a huge incentive to keep on drilling – even at very low prices. If they can cover their immediate costs, which are low relative to the initial outlay, they can make a profit in the short run.

But that creates a ratchet effect: once a well is drilled, only a spectacular fall in the price of oil will stop oil from being pumped. The more oil is pumped, however, the lower the price is likely to fall. Each producer, in this scenario, is trapped into producing more and more, driving down the price further and further. This effect has meant the slowdown in US shale output has been far slower than might have been expected, given the dramatic decline in price.

Electric car boost for Scots

Why not in England too?

Scottish motorists are set to benefit from a £2.5 million electric car fund where they can apply for an interest-free loan of up to £50,000 for electric of plug-in hybrid vehicles.

The Electric Vehicle Loan is open to anyone buying a new electric or plug-in hybrid car or van, and is offered on top of the UK Government’s Plug-in Vehicle Grant.

Open for applications now, the loan will come from Energy Saving Trust coffers and funded by Transport Scotland, the Scottish Government’s transport agency. Intended to cover 100 per cent of the purchase price of a new electric vehicle, the loan can be repaid over a period of up to six years. Business are eligible for the scheme too, with grants of up to £100,000 available for electric vehicles.

Scottish Transport Minister Derek Mackay says:

“Encouraging mass changeover to electric vehicles, from more polluting ones running on petrol or diesel, is a key to cleaner road transport in Scotland and a fundamental factor in achieving our ambitious climate change targets while also improving local air quality.

“Electric vehicles already offer large savings to drivers through reduced fuel and taxation costs and this fund will further encourage new buyers by addressing the current cost premium often cited as a barrier to making the switch. I am pleased we are adding this incentive to the growing package of support measures for EVs outlined in the ‘Switched on Scotland’ policy roadmap.”

Deflationary Collapse Ahead?

Both the stock market and oil prices have been plunging. Is this “just another cycle,” or is it something much worse? I think it is something much worse.

Back in January, I wrote a post called Oil and the Economy: Where are We Headed in 2015-16? In it, I said that persistent very low prices could be a sign that we are reaching limits of a finite world. In fact, the scenario that is playing out matches up with what I expected to happen in my January post. In that post, I said

Needless to say, stagnating wages together with rapidly rising costs of oil production leads to a mismatch between:

  • The amount consumers can afford for oil

  • The cost of oil, if oil price matches the cost of production

This mismatch between rising costs of oil production and stagnating wages is what has been happening. The unaffordability problem can be hidden by a rising amount of debt for a while (since adding cheap debt helps make unaffordable big items seem affordable), but this scheme cannot go on forever.

Eventually, even at near zero interest rates, the amount of debt becomes too high, relative to income. Governments become afraid of adding more debt. Young people find student loans so burdensome that they put off buying homes and cars. The economic “pump” that used to result from rising wages and rising debt slows, slowing the growth of the world economy. With slow economic growth comes low demand for commodities that are used to make homes, cars, factories, and other goods. This slow economic growth is what brings the persistent trend toward low commodity prices experienced in recent years.

Anxiety turns to fear

The characteristic feeling of the post-2008 world has been one of anxiety. Occasionally, that anxiety breaks out into fear as it did in the last two weeks when stock markets around the world swooned and middle class and wealthy investors had a sudden visitation from Pan, the god from whose name we get the word “panic.” Pan’s appearance is yet another reminder that the relative stability of the globe from the end of World War II right up until 2008 is over. We are in uncharted waters.

Here is the crux of the matter as expressed in a piece which I wrote last year:

The relentless, if zigzag, rise in financial markets for the past 150 years has been sustained by cheap fossil fuels and a benign climate. We cannot count on either from here on out….

Another thing we cannot necessarily count on is the remarkable geopolitical stability that the world experienced for two long stretches during the fossil fuel age. The first one lasted from the end of the Napoleonic Wars in 1815 to the beginning of World War I in 1914 (interrupted only by the brief Franco-Prussian War). The second lasted from the end of World War II in 1945 until now.

Following the withdrawal of U.S. military forces from Iraq, the Middle East has experienced increasing chaos devolving into a civil war in Syria; the rapid success of forces calling themselves the Islamic State of Iraq and Syria which are busily reshaping the borders of those two countries; and now the renewed chaos in Libya. We must add to this the Russian-Ukranian conflict. It is no accident that all of these conflicts are related to oil and natural gas.

As I view the current world landscape, I am reminded of two movies (which I’ve written about before) that I think capture the zeitgeist: Melancholia and Take Shelter. In both the protagonists increasingly sense that something is terribly wrong, but can’t quite put their finger on it. Everyone around them thinks they are ill or crazy. But for both protagonists, their anxiety comes from an inner vision that stems not from mere psychic disturbances, but rather from alarming real-world circumstances that are about to break into the open.

In a sense, these two characters represent those of us who cannot repress the pervasive anxiety of our times and who seek not merely to alleviate it, but rather to face it–to find out its origins and address its causes.

If Paris succeeds Citigroup sees $100 trillion of stranded assets

The business world is finally waking up

If you hear a lot of noise about climate policies and climate action over the next few months in the lead up to the Paris climate conference, it is because there is a lot at stake. According to Citigroup analysts: $US100 trillion of potential stranded assets in the fossil fuel industry.

A new Citigroup report values the fossil fuel reserves that need to be left in the ground if the world is to meet its targets of trying to limit global warming to 2°C – a target that, according to a new Climate Council report, is actually a lot less “safe” for humankind than the science thought it was just 10 years ago.

Nevertheless, that is the stated target of all governments – including Australia’s – and Paris will endeavour to put in place a mechanism that will allow the world to meet that goal.

But if the world is serious about meeting this target, it needs to respect its “carbon budget” – and that calls for one-third of global oil reserves, one half of global gas reserves, and 80 per cent of global coal reserves to remain in the ground.

This graph sums up the findings of a new analysis published this year in Nature by McGlade and Ekins. The green represents the percentage of the various fossil fuel types that could be extracted under a 2C scenario.


Translating that into dollar terms, and using metrics of $US70 per barrel of oil, $US6.50/MMBTU of gas (an average weighted price of US, European and Asian prices) and $US70 per tonne of coal, that amounts to a lot of money.

“We estimate that the total value of stranded assets could be over $US100 trillion based on current market prices,” Citigroup notes in the report. And coal bears the brunt, accounting for more than half the value of stranded assets, even in the unlikely event that carbon capture and storage becomes a viable technology.

You might as well have fun as you change

A thought-provoking view (from 2012)

I spend much of my life making the case for changing one’s life (and not just one’s life – for supporting political and social change that is associated with it) in fairly radical ways, very quickly. I spend a lot of my time writing about this, and periodically I get on a train or a bus or something and go stand up in front of people and make the same case. I know this is a diffcult thing for many people, whose infrastructure envelopes them and pushes them powerfully towards a particular way of life, so I try to make good arguments for doing it now. I make moral arguments, about the use of a fair share. I make political arguments about not giving our money to causes we abhore. I make economic arguments. I make the argument that it will probably be a lot easier to adapt later if we have some practice.

But in the last year or two, I’ve been debating with myself how necessary I think these arguments actually are. Don’t get me wrong – I think there are still compelling moral arguments to choose to live in a certain way, and to support certain responses to climate change and depletion. For me personally, these are the most compelling possible reasons for doing this – even if climate change and depletion weren’t a reality, the truth is that Americans can only consume as they do if they tell themselves that other people in the world really won’t mind if they take more than their share, and of course, we all know that’s complete nonsense.

But I also think that the days of being able to choose to live with less are probably over. My prediction for the coming decade is pretty simple – we’re headed fairly rapidly into a time past all choosing. If the “aughts” were about the growing recognition that things are going to change, the teens, I think are now about the growing reality of that change – the recognition that none of us have the resources, or the wealth, or the immunity from changing circumstances to resist change for very long. The question is how we will change, not whether we will.

What do I mean by this? I mean that whether it comes from a worldwide economic crisis (begun already, not nearly as resolved as people say, and likely to be ongoing), from the gradual end of growth, from carbon finally being priced appropriately at the mine/well/etc…, from the costs of dealing with a rapidly increasing number of natural disaster linked to our lack of ecological awareness, from actual energy shortages or simply extremely volatile energy prices, from rising poverty and unemployment that absorb more and more of us or from failing infrastructure as we face the costs of not maintaining our sewers, electric greed, soil, water systems…. it is going to be increasingly impossible for most of us to go on as we have been.

It is no accident that the bills come due pretty much all at once in this decade. This is the decade, for example in which we can probably expect to firmly establish our oil peak, and if the promise of shale fails, as it may, our gas peak as well. This is the decade in which we run out of money to pay the Medicare bill (2017) and in which we have really begun to see the growing consequences of climate change – an ice free summer arctic, the first one in which we expect really big waves of climate refugees, etc…  This is the decade in which our deferred maintenence will begin to come due as more and more of the things we’ve left undone come back and bite us in the ass. This is the decade when we begin paying for all the things we were borrowing for in the last few years. How do we know this is true? Well, the most obvious reason is that these things are already happening.

Domestic batteries help the grid

Let’s hope one day schemes like this get to the UK

Energy provider Ergon Retail is running a trial, with support from the Australian Renewable Energy Agency (ARENA), in 33 Queensland homes in Toowoomba in the south of the state and Townsville and Cannonvale in the north.

In recent months, about 30 country householders have joined a pilot project that provides a glimpse of the future of our energy grid.

For no up-front cost, these homes will get a state-of-the-art rooftop solar and battery system installed in their homes.

Participants will pay a monthly fee to use the battery system, with their electricity bills expected to be significantly reduced because about 75 per cent of their power will be generated by the sun. Their shiny new cabinet-sized battery will allow them to store some of the energy from their solar panels that they then use during peak times – usually in the early evening.

For its part, Ergon will be able to remotely control and monitor these home batteries, and feed power back into the grid when the network is being stretched. The company talks about these in-home batteries as “virtual power plants” that will act to smooth out demand and strengthen the network.
