Australia’s Energy Markets Are Broken Because They Ignore Externalities

You would think the middle of a horrendous bushfire season — at a time when large areas of New South Wales were ablaze and air quality in Sydney was worse than Shanghai thanks to smoke hanging in the air like the ghost of gums before drifting out to sea — would be a bad time for the Australia Energy Market Operator (AEMO) to announce they are okay with people dying from fossil fuel use as long as someone is making money from it.

It’s not about safety – it’s about cost. Nuclear power is just too damn expensive for Australia.

Last Friday the House Of Representatives released a report on nuclear energy in Australia.  They said it’s a good idea — provided everyone is cool with it. [Read more…]

The “solar rebate” does not end this year. In fact rooftop solar power may be cheaper early next year.

DON’T PANIC!  Despite attempts by dodgy advertisers¹ to convince you otherwise, the “solar rebate” isn’t ending any time soon.  Renewable energy certificates (called STCs) will still be lowering the cost of rooftop solar for years to come.  To be precise, for another 11 years, 1 month, and 2 days.

If you asked me how much solar you should put on your roof I would say, “As much as you can without doing something stupid like borrowing from the mafia or doubling up on solar panels by stacking them on top of each other.”  In other words, install as much as you can without making problems for yourself.

Low Cost Renewables Will Soon Drive Coal Power Out Of The Market

Last month the entire country sweltered under an oppressive heatwave — except the half known as Western Australia.  As air conditioner power consumption soared on the 25th, 40% of Victoria’s coal generators failed followed by rolling blackouts. When faced with this incontrovertible evidence of coal’s unreliability, the government dedicated itself to the rapid phaseout of coal under its “affordable, reliable 24/7 power” program.

Sorry, only kidding.  What they actually did was offer to pay the debts of new coal power stations that go bust. [Read more…]

Why Australia Is Unlikely To Ever Export Large Quantities Of Hydrogen

As Michael reported this week, Labor has announced in a media release that, if elected, they will spend $3 million building a “National Hydrogen Innovation Hub” in Gladstone and make over $1 billion available in loans for to develop hydrogen production.  Labor also say they will remove regulatory barriers and make research into hydrogen production, storage, and transport a priority .

Do batteries save money with time-of-use tariffs?

Home battery systems continue to fall in price — with an exception or two — and we are getting closer to the day when they will save a typical household money without subsidy or being part of a Virtual Power Plant.

But there is one thing that almost gets batteries to pay for themselves right now: the ridiculously expensive peak rates some time-of-use electricity tariffs charge.  But, without a subsidy, time-of-use tariffs and batteries will only save money for a few exceptional households.  [Read more…]

Suntenants offers simple solar for renters.

Update August 25th 2021:  Sun Tenants is no longer in operation.

Almost one-third of Australians live in rental properties.  This is a problem because tenants don’t like paying their own money to put solar panels on their landlord’s roof and few landlords see solar power as a good investment.  Because of this, lots of the population are missing out on the savings solar slathers all over electricity bills.  It also prevents the world benefiting from the extra clean energy that would be generated. [Read more…]

The cost of rooftop solar continues to fall despite the fact that the Australian dollar has been falling too.  It has been a while since I’ve harped on about how cost effective rooftop solar is, so I stayed up all night to make beautiful graphs of the simple solar payback time in every capital city.  In other words I will show you how many years it will take the savings on your electricity bills to cover the cost of your solar power system.
