That this House: (1) notes with concern the impact on the Dairy Industry of the Coles milk pricing strategy and that: (a) dairy farmers around the country are today seriously questioning their future having suffered through one of the worst decades in memory including droughts, floods, price cuts and rising cost of
inputs such as
energy and feed; (b) unsustainable retail milk prices will, over time, compel processors to renegotiate contracts with dairy farmers and the prospect that these contracts will be below the cost of production may force many to leave the industry; (c) the fact that supermarkets are now selling milk cheaper
than many varieties of bottled water will be the straw that finally breaks the camel's back for many dairy farmers; and (d) the risk of other potential impacts includes: (i) decreased competition as name brands are forced from the shelves; and (ii) the possible loss of fresh milk supplies to some parts of the country as local fresh milk industries become unviable; and (2) calls on the Government to: (a) ask the ACCC to immediately examine the big supermarkets and milk wholesalers after recent price cuts to ensure they do not have too much market power and are not anti-competitive in their behaviour; and (b) support the new Senate inquiry into the ongoing milk price war between the country's major supermarket chains».
By following carbon emissions in more

than diesel or petrol, because of the
energy intensive refining process, the
energy input to farming, and fertilizer production and use.

And in addition, think about all the wasted
energy the «climate community» spent mitigating the impact of «deniers,» when «skeptics» could have helped out by listening more carefully to the «climate community,» and trying to understand «the climate community's» arguments, and adding to progress on increasing our understanding of the causes of climate variability and change — rather
than apologizing or ignoring the
input from scientists like Fred Singer — who deliberately lifts a conditional clause from a larger sentence, divorces it completely from context, and creates a fraudulent quotation in order to deliberately deceive, or Ross McKitrick who slanders other scientists on purely speculative conclusions about their motivations, or guest - posters at WUWT who call BEST «media whores,» or the long line of denizens at Climate Etc. who falsely claim that the «climate community» ignores all uncertainties towards the goal of serving a socialist, eco-Nazi agenda to destroy capitalism.
Solar PV is reaching that point now (I think it's in Japan), where PV

The real world is, of course, more complicated; instead of a «glass» you have the greenhouse gases in the atmosphere, but the point is that as long as * some * of the

than it would be if they were not there, in order for the next flux into space to match the solar
input Iin.
Agriculture in industrialized countries is generally much more

It's not (necessarily) true that, if
energy input is higher
than energy output, oil extraction is unfeasible.
I am not arguing against what you say, just trying to understand the mechanism... I have always known an object cools more slowly and reaches a higher equilibrium temperature in a warm surroundings
than a cold one, but had considered that an effect of gradient, not as you say a result of
energy input from the colder surroundings.
Using tax incentives for landlords to upgrade
energy efficiency, with a focus on outcomes rather
than inputs or a combination (with an
