Solar options

Creating electricity at home: the cleanest and most sensible option under the sun

It may appear counter-intuitive, but getting millions of solar panels onto rooftops saves more money than it costs. Feed-in tariffs enacted by state governments have enabled ordinary Australians using their savings to build a solar power station at home benefiting the community.

When those solar households who had saved to get their panels installed under the solar feed-in tariff programs export their solar production to the grid, which occurs mostly during higher demand daytime periods, they are given a slightly higher than average retail rate for the electricity they are selling. The prices they have been paid are relatively meagre when compared with the ridiculously high rates paid to big coal or gas power plants.

At the same time that little solar households who have invested their money in a rooftop power station are being paid between 44¢ and 60¢ per kilowatt hour, the old power companies with their dirty belching coal and gas plants are receiving as much as $12.50.

In other words, the coal and gas guys are being paid as much as $11.90 more than a home solar generator for just one unit of electricity...

 
Green fuel fails to meet emissions standards


THE NSW government's plan to ban regular unleaded fuel has been thrown into doubt by the revelation that the state's only ethanol producer, Manildra, has failed the government's clean fuel test, with its ethanol producing more greenhouse gas emissions than previously thought.

New modelling by the Productivity Commission has shown the ethanol produced by the Manildra Group is only 42 per cent more efficient than unleaded petrol, falling short of the target set by the government regulator, Office of Biofuels, which says ethanol should have 50 per cent lower greenhouse gas emissions than fossil fuels.

Manildra maintains its ethanol is produced from waste products and therefore virtually emissions-free, a line supported by the previous NSW Labor government which originally legislated to replace unleaded fuel with ethanol blended fuel.

But evidence has emerged to suggest Manildra's production of ethanol has increasingly relied on the use of food products grown by the company, which the Productivity Commission says accounts for the growth in emissions...

The Office of Biofuels said Manildra told it 80 per cent of its ethanol was made from waste last year but admitted that Manildra's ethanol has never been independently audited.

The new figures from the Productivity Commission contradict Manildra's estimates, which were largely relied on in the former government's decision-making process to phase out regular unleaded petrol.

From July, NSW petrol stations will no longer be permitted to sell regular unleaded petrol because the government wants to promote renewable biofuels. The decision has divided experts over its benefits...
 

Cheaper for power company to shut down its generators


...Macquarie Generation is traditionally the most profitable of the NSW government-owned corporations and generates a high level of dividends, but it expects to pay no dividends to the government from June 2014 as profits collapse.
The carbon tax is only one factor in the foreshadowed reversal of fortunes, as steady rises in power prices have reduced electricity demand, while the strong Australian dollar has forced cuts to industrial output, which is also hitting demand...

Resurgent Kia serves it up to local car makers


...Unlike Ford and GM, and not forgetting Toyota, Kia imports its cars and is therefore not a beneficiary of the automotive industry dole that has been handed out by successive governments. The rationales for the payouts to car makers have always ranged from the prosaic: any self-respecting, large economy needs vehicle making in its portfolio of skills, to the cynical: many a seat in Parliament might swing on thousands of direct, and indirect, job losses if the car plants ceased output.
 
Government assistance and rescuing of large-scale vehicle makers is a tried and true exercise, although history suggests that in most cases it has merely delayed the inevitable for ultimately uneconomic businesses...

A simple source


A new website will connect consumers with their food, writes Paul Mitchell.

Wherever you live, food co-ops, swap meets, community gardens, farmers' markets, free-range producers, box systems and organic retailers are likely to be mushrooming around you. But keeping abreast and plugging into such networks can be daunting.

Enter Nick Ray, who has created a free online resource called Local Harvest. Launching next month, it will be a hub for consumers concerned about where their food comes from and how it's produced. By keying in your postcode, the contact details and other information about sustainably produced food in your neighbourhood will appear...
