How much useful electricity does rooftop solar produce in southern Western Australia

The ABC have this article claiming – Rooftop solar producing more energy than WA’s biggest turbine – Curtin University sustainability professor Peter Newman said – “It’s nearly 500 megawatts and it’s growing rapidly,..” Yet when I check NemWatch for WA I can only ever find a little over ~250MW for WA small solar. Is this because about half the output is used in the homes of the owners of these rooftop solar systems?
And of course the article seems to forget that these solar systems only work in the sunny hours – they make no electricity at night while the coal fired generators chug away 24/7. I wonder to what extent the WA grid can keep on accommodating increasing solar and wind power yet remain stable. I also wonder what is the cumulative cost of all the small scale solar subsidies paid out by the various Australian Governments.

Green electricity prices increase – how does the GreenLeft media publish such rubbish with a strait face

They are instrumental in inflicting this disaster on us all – utterly no shame. New year rings in 41 per cent rise in GreenPower prices
Has anybody got any other increases to quote. How about us that If anything, which disrupts get free viagra miamistonecrabs.com brain being stimulated and getting ON can be responsible for the erection breakdown. The skilled, well- trained and hospitable staff offer the support needed. If you are drugs buy tadalafil 20mg affected then you can also take help of herbal pills that can prove to be more beneficial than it costs. When adopted, these pills ensure that people are now turning to their phones and their computers to get things done. do not buy the fraud of so called Green Power? Do we really think charges for normal electricity are not also going up? We have to stop voting for the disaster of steadily wrecking our electricity grid.

GreenLeft Australian ABC repeats anti-coal story five times on news front page

It must cruelly piss them off that global wind plus solar electricity generation in 2014 tallied only 3.8%

This is the yarn repeated five times – Are we witnessing a turning point in the future of coal?
Here is a chart of global electricity generation –

Media claims that peak oil is postponed because of renewables are the wildest fantasy

We all know that the world crude oil price crashed starting mid 2014 – from levels around $100 per barrel it is now ~$35. Obviously fracking in the USA has boosted oil production but an additional reason for the price crash is the Saudis economic warfare to minimise the power of Iran post sanctions. I posted on that subject about a year ago. Saudis oil pumping crashes oil price kneecapping the Iranian economy – how do the Teheran Mullahs pay to build those nukes now? Anyway – back to the subject today. The ABC reports – Peak oil losing credibility as renewables shift accelerates and Fairfax chimes in – The price drop that’s really worrying big oil
To put renewables on scale with global oil consumption I have made this chart using data from the BP Statistical Review of World Energy – get the XLS file and explore for yourself. Oil consumption has been converted to Terrawatt Hours to compare with solar and wind global electricity generation. It is crystal clear that the microscopic quotas of heavily subsidised renewables in the bottom right corner of my chart could not possibly be having any serious influence on the massive global consumption of oil.

If you want to add global coal consumption on for 2014 that is another 17,000TWh equivalent and global electricity consumption all sources in 2014 totals 23,536TWh. I wonder where this Green/Renewables fantasia originated.

Brilliant Agora Energiewende online graphic display of German electricity generation

Look at the pathetic contribution of wind and solar recently – Agora Energiewende

In July solar was better of course but wind was a lot worse – you can check any period.
No wonder many western economies are near moribund after wasting squillions on dud technologies thinking they would produce “low carbon” electricity in a way acceptable to the population. Amazing that people still vote Green or Left. Deluded. I read where members of Merkel’s cabinet have the common sense to see the train-wreck coming. Germany abandons their climate target, as their Chancellor sings to the crowd

Green renewable energy enthusiasts hoping to buy back the Berlin electricity grid

Yes that’s Berlin, Germany – what about Berliners who actually want reliable electricity – do they get any say.
The Australian ABC reports – Berlin citizens looking to buy back electricity grid in aim of using more renewable energy
Without fossil fuels, hydro or nuclear it could easy be a case of – Ich bin ein Berliner in der kalten und dunklen. Thanks Google for translating.

Australian fuel cell company attracted by the German Energiewende

The ABC reports that ASX listed fuel cell company Ceramic Fuel Cells Limited (ASX – CFU) with origins as a CSIRO spinoff is headed to find its place in the sun as a part of Energiewende. – Germany’s renewable energy incentives and regulations attracting Australian companies
One of their products is BlueGen a gas fired fuel cell, they say –
BlueGen can be installed on-site in your home or business. It contains standard connections and operates with virtually no noise. Key benefits include:
Up to 36 kilowatt-hours of electricity per day
200 litres of ‘free’ hot water per day
Carbon dioxide savings of up to 14.5 tonnes per year
Unconstrained by seasons or weather
Simple installation with standard connections
Integrates easily with renewable technologies such as solar PV or solar thermal hot water
Constantly monitored by advanced fault detection technology

All sounds good. Here is the CFU share price history – a great thing about the ASX is that all regulatory filings and company announcements are easily searched and downloaded as pdf’s.
