    Those of us who were around in 1975 would have felt a sense of deja vu when they heard the Opposition Senators say that they intended to reject the Rudd government’s budget. Not that Fraser’s Opposition rejected supply; they merely refused to consider the Bills which meant that no vote was ever taken.

    The wording of the Australian Constitution on their actions is interesting. The Chief Justice, Sir Garfield Barwick, thought that the Senate had the power to do what it did; but as a former Liberal Minister, he was unlikely to criticise the very tool chosen by the Liberal Opposition to bring about the crisis that would move Kerr to dismiss Whitlam when, at the same time, he was also advising Kerr.

    But the wording of the Constitution on this point is very interesting. Section 53 which deals with this supposed power does say, expressly, that the Senate may not amend any proposed taxation or appropriation bills. As was his way, Barwick read this to mean that the Senate could do everything else but it could not amend the legislation.

    Barwick’s reading of the Constitution is therefore at odds with what the Constitution actually says. Why would a Constitution remove a particular power from the Senate but, according to Barwick, provide it with as many practical alternatives of achieving the same end as malicious minds can invent? Who needs the power to amend if an Opposition controlled Senate can hold an elected government penniless until they agree to its amendments?

    Barwick may not be around to answer these questions, but his legacy of reading the Constitution is at home in the hands of Opposition members who have a vested interest in finding obscure powers that might never have been intended by the founding fathers.

    If we look at what the founding fathers intended, we find that section 53 incorporates, quite succinctly, the traditional understanding of the relationship between the House of Commons and the House of Lords in respect of appropriations and taxation bills. The following passage from Wikipedia states the practice accurately:

    Even before the passage of the Parliament Acts, the Commons possessed pre-eminence in cases of financial matters. By ancient custom, the House of Lords may not introduce a bill relating to taxation or supply, nor amend a bill so as to insert a provision relating to taxation or Supply, nor amend a Supply Bill in any way.

    This convention, which vests the power of the purse in the popularly elected chamber, was, like the convention that the monarch only acts on the advice of the Prime Minister, incorporated implicitly into the Australian Constitution by our Founding Fathers. Both conventions had been long recognised and adhered to in the United Kingdom at the time of our Constitution’s drafting. We may suppose that the conventions were so well known at the time, that it was not considered necessary by those men, that anything more than a general statement of principle was needed. It was, after all, such a reasonable and practical way of acknowledging the source of the government’s power in the people. Barwick and the Liberal Opposition thought differently.

    However, as one learned commentator said, once it is accepted that a Senate can block or reject supply, everything after the first sentence of section 53 is redundant.

    We are experiencing again the vision of a party, defeated at the polls, its government unceremoniously dumped from office by the people, unable to accept its proper role as an Opposition. Instead it has imagined a power into existence that it can use to bend a government to its will: government by Opposition. This is the power to reject supply that it has appropriated to itself.

    It is not too late for our newly appointed Governor General to put the situation right. She should advise the Senate that it does not possess the power that it claims to have and that she has the power to sign taxation and appropriation bills into law without the consent of the Senate.

  • A battle is looming over renewable energy, and fossil fuel interests are losing

    A battle is looming over renewable energy, and fossil fuel interests are losing

    Charlie Riedel/AP – Wind turbines are silhouetted by the setting sun near Beaumont, Kan. Kansas ranks sixth in the country in wind output, which jumped by a third last year and equalled 19 percent of the state’s electricity.

    By and , Published: April 26 E-mail the writers

    In state capitals across the country, legislators are debating proposals to roll back environmental rules, prodded by industry and advocacy groups eager to curtail regulations aimed at curbing greenhouse gases.

    The measures, which have been introduced in about 18 states, lie at the heart of an effort to expand to the state level the battle over fossil fuel and renewable energy. The new rules would trim or abolish climate mandates — including those that require utilities to use solar and wind energy, as well as proposed Environmental Protection Agency rules that would reduce carbon emissions from power plants.

     

     

     

    But the campaign — despite its backing from powerful groups such as Americans for Prosperity — has run into a surprising roadblock: the growing political clout of renewable-energy interests, even in rock-ribbed Republican states such as Kansas.

    The stage has been set for what one lobbyist called “trench warfare” as moneyed interests on both sides wrestle over some of the strongest regulations for promoting renewable energy. And the issues are likely to surface this fall in the midterm elections, as well, with California billionaire Tom Steyer pouring money into various gubernatorial and state and federal legislative races to back candidates who support tough rules curbing pollution.

    The multi-pronged conservative effort to roll back regulations, begun more than a year ago, is supported by a loose, well-funded confederation that includes the U.S. Chamber of Commerce, the National Association of Manufacturers and conservative activist groups such as Americans for Prosperity, a politically active nonprofit organization founded in part by brothers David and Charles Koch. These groups argue that existing government rules violate free-market principles and will ultimately drive up costs for consumers.

    The proposed measures are similar from state to state. In some cases, the legislative language matches or closely resembles model bills and resolutions offered by the American Legislative Exchange Council (ALEC), a free-market-oriented group of state lawmakers underwritten in part by Exxon Mobil, Koch Industries, Duke Energy and Peabody Energy.

    “Now more than ever is the time for states to lead the way,” ALEC’s top officials told its members at a meeting in December.

    The coalition campaigns have achieved only symbolic victories in a few states. Nonbinding resolutions critical of the EPA power plant proposals have been approved in Alabama, Georgia, Nebraska, West Virginia and Wyoming. Three other states — Louisiana, Missouri and Ohio — are weighing legislation similar to the ALEC model.

    Only one of the 18state legislatures has approved a more substantive measure that would preempt the EPA’s power plant rules. And even that bill, in Kentucky, could backfire by giving up a chance for the state to design its own program and forcing it to accept a federal compliance program.

    “Clean energy is beginning to become mainstream,” said Gabe Elsner, executive director of the Energy and Policy Institute, a clean-energy think tank in Washington. “Renewable energy is popular and has increased political power now,” but, he added, “that power is still eclipsed by the resources of the fossil fuel industry.”

    A surprisingly tough fight

    Kansas might be the best place to see how these dynamics are unfolding.

    The state was a promising choice for a foray against rules known as renewable-energy standards, which set minimum levels of renewable-energy use by electric utilities. Variations of these rules have been adopted in about 30 states, even though Congress did not pass a federal version of the requirement. In Kansas, a law passed in 2009 requires utilities to use wind and solar power to generate at least 15 percent of their electricity by 2016 and 20 percent by 2020.

    The coalition seeking the repeal of the renewable mandate had all the ingredients for success.

    Financial muscle came from the Kansas Chamber of Commerce, which lobbied heavily for repeal. In addition, the state is home to Koch Industries, the Koch brothers’ Wichita-based energy conglomerate. The state representative for Wichita, Republican Dennis Hedke, has called the company “one of the greatest success stories in the world” and said “they are making very positive contributions.” Hedke chairs the state House’s Energy and Environment Committee.

    Koch Industries, along with the utility industry’s Edison Electric Institute and the nation’s biggest coal company, Peabody Energy, have supported ALEC, which advised state lawmakers on repeal strategy.

    “Koch has consistently opposed all subsidies and mandates across the board, especially as it relates to energy policy,” Philip Ellender, president and chief operating officer of Koch Companies Public Sector, said in a statement, citing the company’s opposition to the renewable fuel standard, wind production tax credit and ethanol mandate. “Government should not mandate the allocation or use of natural resources and raw materials in the production of goods.”

    The ideological case was buttressed by conservative think tanks. Kansans for Liberty supported repeal, and the state branch of Americans for Prosperity told supporters that “green energy mandates replace the free-market with bureaucratic government oversight, driving up costs for hard-working Kansas families.” The national group has spent $300,000 in the state pushing for the rollback of renewable standards.

    Connections to key Kansas politicians also were strong. Both the Kansas state Senate’s president, Susan Wagle (R), and the speaker of the state House, Ray Merrick (R), are members of the ALEC board and backed repeal.

    “The repeal of the RPS [renewable portfolio standards] fits in line with the goals of the organization,” said Wagle, who said she joined ALEC in the 1990s in connection with her opposition to health-care reform led by Hillary Rodham Clinton, then the first lady.

    Moreover, the Kansas economy relies heavily on fossil fuels. The state is the nation’s 10th-largest producer of crude oil and 12th-largest of natural gas, according to the federal Energy Information Administration. In 2013, coal-fired power plants provided 61 percent of the state’s electricity, well above the national average.

    But the strong winds that blow across Kansas have carried new interest groups into the state. Kansas ranks sixth in the country in wind output, which jumped by a third last year and equaled 19 percent of the state’s electricity, the EIA says.

    The growing number of wind farms not only generate power but royalties for landowners. Dorothy Barnett, executive director of the Climate and Energy Project, said that Kansas landowners receive more than $13 million a year. “This issue is an issue that touches rural Kansans, and we have a lot of rural Kansas legislators,” she said.

    Wind proponents cite manufacturing jobs, too. At a plant in the state, Siemens is making nacelles, the automobile-size units that contain wind-turbine gearboxes and electronic control equipment, for the biggest turbine order ever for wind farms in Iowa.

    Supporters of repeal had trouble making the argument that the renewable-energy mandate had raised electricity rates by 40 percent, as ALEC asserted. The Kansas Corporation Commission reported that the rate impact of renewable-energy standards was about 0.16 cents of the 9.2-cent retail cost of electricity per kilowatt hour. It said that meeting the requirement “requires less than 2 percent of the revenue requirement of the utilities while supplying more than 10 percent of the generation capacity in the state.”

    Hedke said the commission overlooked certain costs, such as repair and retirement. He wants the commission to “drill down deeper.”

    Conspicuously silent during the entire debate has been Gov. Sam Brownback (R), a leading conservative politician who as a U.S. senator vigorously supported federal production tax credits for wind developers. The state legislature’s Republican leaders met with him.

    “I do not believe he will veto a bill, but he also is not likely to come out in support of the bill,” Hedke said when the repeal debates were intense. “He’s stayed on a particular path, and people in leadership disagree with him.”

    Eventually, the Kansas Senate passed two bills, one postponing the renewable targets and one repealing them. Both failed in the state House, although the bill’s backers have vowed to bring them back.

    The campaign continues

    Meanwhile, similar coalitions are trying to thwart regulations in other states.

    In Ohio, which relied on coal for 69 percent of electricity generation in 2013, the push to reverse the renewable-energy standards is very much alive, with the Akron-based utility company FirstEnergy leading the charge.

    Environmental groups who are fighting to protect Ohio’s renewable-energy standards fear that the heavily Republican legislature will vote in favor of the reversal, so they are placing their faith in Gov. John Kasich (R). He has given qualified support to renewables in the past, saying in his 2012 State of the State address that, although the state should avoid anything that drives up costs for residents, “we need to embrace renewables.”

    This year, he hasn’t taken a position on the reversal bill. Opinion polls in Ohio show widespread support for expanding renewable-energy use, and Kasich is running for reelection this year. But the governor, who won by a slim margin in 2010, is thought to harbor ambitions for national office, and it isn’t clear how the issue cuts for him politically.

    The battle also has stretched to West Virginia, where a bill designed to preempt EPA regulations was amended with language that basically “defanged” it and made it symbolic, said Aliya Haq, who monitors state efforts for the Natural Resources Defense Council.

    Months ago, ALEC had distributed a report called “The EPA’s Assault on State Sovereignty,” suggesting constitutional and economic arguments against the new power-plant and other environmental rules.

    “I’m not going to let the EPA have an unabated run at the American economy,” said Hedke, the Kansas legislator

    A NASA scientist is launching a one-to-two-year pilot project this summer that takes advantage of U.S. high-voltage power transmission lines to measure a phenomenon that has caused widespread power outages in the past.

    Heliophysicist Antti Pulkkinen of NASA’s Goddard Space Flight Center in Greenbelt, Md. and his team are installing scientific substations beneath high-voltage power transmission lines operated by Virginia’s Dominion Virginia Power this summer to measure in real-time a phenomenon known as geomagnetically induced currents (GICs). “This is the first time we have used the U.S. high-voltage power transmission system as a science tool to map large-scale GICs,” Pulkkinen said. “This application will allow unprecedented, game-changing data gathering over a wide range of spatial and temporal scales.”

    In addition to gathering data important to the power industry — especially if it’s expanded nationwide as currently planned — the project will allow heliophysicists to “reverse engineer” the data to learn more about the conditions in Earth’s upper atmosphere that lead to the generation of GICs during severe space weather events, Pulkkinen said, adding he is now developing computer algorithms to extract that data for scientific research. “Not only will this benefit the utility industry, it also benefits science,” he said.

    Solar Storms the Culprit

    GICs typically occur one-to-three days after the sun unleashes a coronal mass ejection, or CME, a gigantic bubble of charged particles that can carry up to 10 billion tons of matter. CMEs can accelerate to several million miles per hour as they race across space. If a CME slams into Earth’s magnetosphere, the impact causes electromagnetic fluctuations, which result in geomagnetic storms at Earth. These storms increase electric currents that in turn, drive the fluctuations in Earth’s magnetic field near the ground. These surface currents can flow through any large-scale conductive structure, including power lines, oil and gas pipelines, undersea communications cables, telephone and telegraph networks, and railways.

    An extreme example of a GIC occurrence was the great magnetic storm of March 1989 — one of the largest disturbances of the 20th century. Rapid variations in the geomagnetic field led to intensely induced electric fields at the Earth’s surface. This electric field caused electrical currents to flow through conducting structures — in this case, the Canadian Hydro-Quebec power grid. The excess current collapsed the transmission system, causing the loss of electric power to more than six million people.

    According to the U.S. Geological Survey, had the blackout occurred in the Northeastern U.S., the economic impact could have exceeded $10 billion, to say nothing of the deleterious impact on emergency services and reduction in public safety.

    Space weather events can have a range of effects including disrupting communications and navigation systems, damaging satellite instrumentation, and even potentially corroding pipeline steel. The impact on the nation’s electric grid is perhaps the highest concern at the moment, Pulkkinen said. “It’s the hottest topic out there right now,” he said, adding that the Federal Energy Regulatory Commission is now developing standards to mitigate the GIC threat. “We need to better understand how these events affect the U.S. power grid,” he added.

    His pilot program is designed to help find out, Pulkkinen said.

    Funded by R&D Programs

    Funded by NASA’s Center Innovation Fund and Goddard’s Internal Research and Development (IRAD) program, the team is creating three substations, all equipped with commercially available magnetometers capable of precisely measuring the variable magnetic fields associated with GICs. Once inserted inside a protective, watertight housing unit, designed by Goddard engineer Todd Bonalsky, the team will bury the gear four feet into the ground — two directly below Dominion Virginia Power’s high-voltage lines and the third one-to-two miles away. The latter will provide reference measurements.

    “In essence, we’re tapping into a very large antenna, Pulkkinen said. “The high-voltage lines are the antennae. During solar storms, violent changes in the electric current occur in near space, which then are sensed by the transmission lines.”

    Ubiquitous iPad Finds Scientific Application

    To command and control the magnetometers, Pulkkinen’s team is using another IRAD-developed technology, LabNotes. This iPad application, developed by Goddard engineers Carl Hostetter and Troy Adams, will time tag and geo-locate the magnetometers’ data, and then deliver the information to a server via a cellular data network, Hostetter explained. In addition to sending one sample per second, the LabNotes-equipped iPad-Mini also could monitor the data and send a text message should an event warrant attention.

    “Now that everyone is walking around with this type of computer, which is more powerful than some supercomputers of 15 years ago, we thought we may as well use it for scientific purposes,” Hostetter said, adding that its relatively small size and low-power consumption make it ideal for science gathering. Although Pulkkinen’s team is the first to actually use the application, Hostetter said the technology has interested a number of other projects, including one involving agricultural needs in Africa.

    The Goal: Nationwide Coverage

    The project’s objective, Pulkkinen added, is making the equipment as inexpensive and versatile as possible. Although the pilot project begins with only three substations, Pulkkinen wants to ultimately deploy hundreds across the nation. “We envision that after a one-to-two-year pilot phase, long-term funding from a multi-agency collaboration and public-private partnerships will make this happen.”

    “Impacts to the nation’s power grid are currently the highest space-weather concern in the U.S.,” he added. With federal regulations on the horizon, Pulkkinen said the measurements would help define the most effective techniques for mitigating GIC threats.

    Climate change: Don’t wait until you can feel it

    Summary:
    Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New research shows that even as extreme weather events influence those who experience them to support policy to address climate change, waiting for the majority of people to live through such conditions firsthand could delay meaningful action by decades.

    Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New work from Carnegie’s Katharine Ricke and Ken Caldeira focuses on the intersection between personal and global impacts. They find that even as extreme weather events influence those who experience them to support policy to address climate change, waiting for the majority of people to live through such conditions firsthand could delay meaningful action by decades. Their findings are published by Nature Climate Change.

    Nearly every year, extreme weather events such as heat waves and hurricanes spur the discussion of climate change in the media and among politicians. This can create a window of opportunity for those seeking to enact policy aimed at reducing greenhouse gas emissions. But this window of opportunity could be delayed by decades due to the vagaries of weather.

    “When support for doing something about climate change is based on personal observations of local weather, policymaking may end up being dictated by the roulette wheel of natural climate variability,” says Ricke.

    Ricke and Calderia’s modeling studies show that within 50 years nearly every country in the world will experience the kind of extreme weather that can be a policy trigger. However, local natural variability in weather means that majority of people in each nation, particularly large countries like China and the United States, could personally experience these extremes for themselves either tomorrow or many years from now. If citizens do not support emissions reductions and other efforts to fight climate change until they experience extreme events firsthand, naturally-driven variations in weather could delay action by decades, Ricke and Caldeira found. They find that sound science should guide policy rather than the vagaries of weather. “Local weather is anecdotal information, but climate change is sound science,” Caldeira said. “Good politics can be based on a good anecdote, but good policy needs to be based on sound science.”

    soil carbonBy modeling the cost of these practices researchers estimate the profit loss for each additional tonne of CO2 stored on the model farm was $80.00 which is far more than the initial buying price of $23.00 per tonne under carbon tax legislation. Image: Jon WhittonNEW UWA research looking at the economic impacts of implementing soil organic carbon (SOC) sequestration methods into farming practices, is showing that these impacts may prove impractical for farmers.

    One of the study’s authors Assistant Professor Marit Kragt says while SOC sequestration has been talked about a lot in public debate, there was little evidence of the impacts it may have on farmers.

    “The government is promising a bunch of money to the farmers if they undertake climate change mitigation action,” she says.

    “That sounds like a great idea but how much would it actually cost farmers to take these measures?”

    All soils contain carbon in organic and inorganic forms and the hope is that by altering practices the amount of carbon held by the soil can be increased.

    The authors found that while altering certain practices can be used to increase carbon sequestration it is costly and farmers would require high levels of compensation to make it a viable option.

    By modeling the cost of these practices researchers estimate the profit loss for each additional tonne of CO2 stored on the model farm was $80.00 which is far more than the initial buying price of $23.00 per tonne under carbon tax legislation.

    A/Prof Kragt says there are also a number of other barriers for the implementation of many practices of carbon sequestration.

    “There are a lot of opportunities to increase soil carbon but pretty much most of those are categorised as conservation practices and those conservation practices won’t be eligible for carbon credits under additionality”, A/Prof Kragt says.

    Additionality is the requirement that any practices implemented create additional sequestration or reductions in emissions than would have occurred under a business as usual scenario.

    She says there is a lot of uncertainty around mitigation efforts and the carbon tax legislation farmers will have to contend with.

    “You have the policy uncertainty where you don’t really know how this policy is going to develop”, she says

    “The other one is all the environmental uncertainty where you could implement all new management practices. [The] hope is to see carbon sequestration or emission reduction […by…] planting trees is all conditional on weather condition, soil condition and bushfires.”

    Ms Kragt says the next part of this research will be based around the real experiences of the farmers who are starting to implement these practices to get a more detailed picture of what impacts they are already having.

    Drought covers 100% of California for first time in 15 years

    A prolonged period of below-average rainfall has put the entire state of California under some level of drought, ranging in severity from moderate to exceptional, for the first time in 15 years.

    The latest drought monitor released by the National Climatic Data Center this week shows that the entire state is under moderate drought conditions, but within that map, 76.6% of the state is experiencing extreme drought conditions, and for 24.7% of the state, the level of dryness is “exceptional.”

    During the same period last year, none of the state was considered to be under extreme or exceptional drought conditions, and just 30% fell under the “severe” category, according to the assessment released Thursday.

    “This is a really serious situation here in California and people need to be cognizant of that and start conserving water as much as they can,” said Jayme Laber, a hydrologist with the National Weather Service who is part of a team of scientists who contribute to the weekly drought monitor.

    The lack of substantial precipitation over the last three rain seasons has affected every part of the state, “some worse than others,” Laber said.

    While many municipalities across the state have instituted voluntary conservation measures, some have gone further. As of May 1, customers in Santa Cruz will have to cut their water use by 25% or face stiff financial penalties. The mandatory restrictions are the first for the city in 25 years, CBS San Francisco reported.

    The statewide situation eased somewhat after soaking rains in Northern California earlier this year allowed the State Water Project, which supplies a majority of the state, to announce that it would make 5% of the system’s allocation — a minor bump from the zero allocation that customers had been expecting.

    Still, NOAA reported last week that half of the Sierra Nevada’s snowpack liquid water equivalent melted in one week, spurred by statewide temperatures that were as much as 12 degrees above average. The melt did little to boost reservoirs.
