"Buried in a little-noticed rule on microwave ovens is a change in the U.S. government's accounting for carbon emissions that could have wide-ranging implications for everything from power plants to the Keystone XL pipeline. The increase of the so-called social cost of carbon, to $US38 ($A40) a metric ton in 2015 from $US23.80, adjusts the calculation the government uses to weigh costs and benefits of proposed regulations. The figure is meant to approximate losses from global warming such as flood damage and diminished crops. (That figure also compares with the $A23 per tonne carbon tax in Australia.)"

"A national survey on energy affordability carried out by CHOICE, the Brotherhood of St Laurence and Energy Efficiency Council revealed 84 per cent of Australian households are concerned or very concerned about energy costs. The same percentage felt it was important or very important for their State Government to help rein in these costs.     However, instead of screaming for renewable energy support to be hit to cut the cost of power - a default choice it seems for many politicians - this was the least popular action in the survey. In fact, knee-capping renewables had a negative net approval rating in every state. "

"The plunging cost of solar PV means that it may now be half the cost of grid-based electricity, according to some industry estimates."

Tired of hearing that sustainable construction has to cost more, Josh and his colleagues want to prove that resource efficient homes can be built at comparable cost and timeframes to regular houses. The homes will be thermally comfortable year round, without the need for air conditioning or additional heating. They will generate more electricity than they use, and will harvest and recycle water. In addition to private garden areas, a common productive garden will supply both houses with fresh food. What sets this project apart from many others is that the building designs have achieved a 10 Star energy efficiency rating*, whilst intentionally using conventional building materials and construction methods so they can easily be replicated by industry and the wider community. The project also demonstrates a more sensitive approach to residential subdivision that has considered maximising effective garden area around the homes to allow for natural shading, children's play spaces and local food production - important health and lifestyle benefits that are rapidly disappearing from our suburbs. Construction started in November 2012 and is scheduled for completion by May 2013.

America's first new nuclear plants in more than a decade are costing billions more to build and sometimes taking longer to deliver than planned, problems that could chill the industry's hopes for a jumpstart to the nation's new nuclear age.

"By the end of this decade, it estimates that onshore wind will be the cheapest source of energy we have. At an average cost of $90 per megawatt-hour (MWh) and in some cases as cheap as $60/MWh it will be cheaper than coal and cheaper than gas. By 2030, the cheapest option will be solar PV, which could cost as little as $50/MWh, followed closely by wind and landfill gas."

"It's been a long, hot summer for most of us and with the run of high temperatures set to continue, air conditioners will keep getting a good workout. But many of us are wasting money through lazy energy consumption and bad habits. Australians have taken to air conditioning in a big way with an estimated 9.2 million units working to keep the summer heat away. Air conditioning is particularly energy hungry with many people wasting money on unnecessarily high electricity bills because they are ignoring a few simple ways to reduce their cooling costs."

"Contrary to many claims, the costs of renewable energy are minor. In 2015, probably the earliest any major changes to the policy could be made, the RET would cost the average household around $1 a week."

"The cost of solar photovoltaic (PV) cells has declined an incredible 99% since 1977. Consequently, a growing number of solar markets are very close to hitting grid parity, Think Progress has reported."

"Climate change isn't an issue for any one government or any one region. Carbon pollution has taken a devastating toll across the planet, from floods in Manila to droughts in Australia. To learn about the global reach of the environmental changes caused by human behavior, take a world tour with the six videos that premiered during Climate Reality Project's 24 Hours of Reality: The Cost of Carbon."

"Many Australian consumers and businesses are working on ways to reduce their greenhouse gas emissions. For some, the carbon tax meets their needs: it's designed to specifically motivate changes in behaviour by raising the costs associated with the production of pollution. But others are looking for more direct measures. Do offsets fit the bill?"

"The fundamental transformation of energy markets brought about by the growing incursions of renewables such as wind and solar has been underlined in a new report by the European energy analysts at Macquarie Group, who have concluded that the plunge in costs for rooftop solar PV has fallen to such an extent that its continued rapid deployment may be unstoppable."

The Wellington Mayor says a compensation deal between council and the developers of a proposed windfarm at Bodgangora has come at a "considerable cost". Rod Buhr says the $2 million Voluntary Planning Agreement with Infigen Energy will be used to upgrade and maintain local roads and to develop a community benefit fund.

"In the US, utilities are now seeking to protect their business models by pushing hard against net metering and seeking to influence the pace and manner of deployment of other technologies and new energy market concept that don't fit the decades old model. In Australia, much the same has been happening. RenewEconomy reported on the concerns of utilities in this article last month. Feed-in-tariffs have been wound back, as they were supposed to have been as technology costs fell, but now the pendulum is swinging the other way, and utilities - with the apparent complicity of state-based pricing regulators - are now trying to extract as much revenue from solar customers as they can."

"On 9 May 2013 The National Sustainability Council presented Sustainable Australia Report 2013 to Minister Burke. The report provides a picture of Australia - what we look like and who we are. It tells the story of how we have changed as a nation over the last 30 years. We have made great progress in many areas. Australians are living longer, our health and levels of educational attainment have improved. We have benefited from a strong economy, with low unemployment and increasing incomes. However, inequality has increased and the health of our natural environment has continued to decline in some key areas. The report provides an evidence base for decision-making and planning about the future. It highlights a number of trends in Australia and the world that are set to have a significant impact on the next generation of Australians. We need to plan for an ageing population, rising health costs, growing cities and changes in traditional work and family roles. The National Sustainability Council intends to use the report, the first of its kind in Australia, as a starting point for a national conversation about our future."

".... behind the scenes a growing number of economists and energy analysts are challenging the assumptions and methods behind these studies. None of them argues against seizing truly cost-effective energy efficiency opportunities. Rather, they caution against overestimating their energy and carbon savings potential. As such, it is time to rethink the privileged place efficiency has taken in the climate and energy strategies of national governments and international agencies. "

Green has become the common term for people who care about the environment or for practices promoted as better for the environment than some other practices. When used for marketing, "green" can become downright misleading. In fact, there's a term "greenwashing" to describe advertising that makes something look greener than it really is. Sustainable, on the other hand, refers to practices designed to have the least impact on the environment, create the least waste, and capable of being carried out indefinitely. That is, something sustainable can't waste resources, can't pollute, can't be dangerous over the long term to life, can't cost so much that it causes social or financial disruption, etc.

"The Coalition will impose new noise monitoring rules on windfarms that the multibillion dollar industry says will inflict crippling costs, provide no useful information and represent another victory for an anti-noise campaign by concerned citizens backed in part by the climate sceptic lobby."

"To explain the latest 20% rise of electricity cost in Queensland, look no further than the free market reforms kickstarted in the 1990s"
