"Batteries are so ubiquitous today that they're almost invisible to us. Yet they are a remarkable invention with a long and storied history, and an equally exciting future. A battery is essentially a device that stores chemical energy that is converted into electricity. Basically, batteries are small chemical reactors, with the reaction producing energetic electrons, ready to flow through the external device. Batteries have been with us for a long time. In 1938 the Director of the Baghdad Museum found what is now referred to as the "Baghdad Battery" in the basement of the museum. Analysis dated it at around 250BC and of Mesopotamian origin."

"More than 1,500 barrels of crude oil per day gushed from the "Jake" oil well when EOG Resources drilled and fracked the well into the Niobrara shale in northern Colorado in the fall of 2009. That gusher marked the beginning of one of the biggest oil booms in the state's history, part of a larger shale oil rush playing out in Colorado, Texas, North Dakota and elsewhere today making the U.S. the world's leader in oil production this year. Those booming shale oil and gas plays are all successful because of advances in fracking and horizontal drilling technology and the speed with which companies are drilling new wells. In some regions, the booms are playing out near homes and schools in suburban areas, particularly in Colorado, where they contribute to widespread concern about climate change-driving methane leaks, air pollution, groundwater contamination and the industrialization of residential areas."

"When we talk about greenhouse gases we usually talk about carbon dioxide. When media reports depict climate change, we invariably see the cooling towers of a coal power station. Which is fair, because carbon dioxide, or CO2, is the big one: nearly 75% of Australia's total greenhouse gas emissions are carbon dioxide. Most of those come from the energy sector and the combustion of fossil fuels. But there are other gases involved in the greenhouse story. Methane and nitrous oxide are also contributors to Australia's greenhouse gas account. And both have a much greater impact on the atmosphere in terms of global warming than carbon dioxide."

"Renewable energy sources such as wind and solar power appear to be the impetus behind a South Australian proposal to substantially drop electricity prices, just as other states are hiking theirs. The Essential Service Commission of South Australian (ESCOSA), which regulates retail electricity prices, has released a draft price determination that proposes an 8.1% reduction in the electricity standing offer, (that is, the default retail price that must be offered to South Australians, at a minimum)."

"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 Endeavour Centre is excited to begin the Canada's Greenest Home project, a residential build in Peterborough, Ontario that we are undertaking with the students in our five-month, Sustainable New Construction certificate program. Throughout the design and construction of Canada's Greenest Home, we will make every effort to publicly detail the entire process on this blog, so please follow along. We are sure to have a steep learning curve, and we want this learning to be a legacy of the project."

"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."

Today the possibilities with pallets are endless, and the materials are often free. If you've got access to pallet wood and basic power tools (and the skills to use them), this project shouldn't take longer than an afternoon."

Australian politicians are displaying a discernible lack of courage in dealing with the threats of climate change, University of Melbourne researchers are warning. 

The effects of global warming will persist for hundreds of years. What are our responsibilities and duties today to help safeguard the distant future? That is the question ethicists are now asking.

"Many Australians are happy to declare their interest in sustainability, to reducing their environmental impact. But how many of them are prepared to reduce the amount they actually consume?"

"Creek Watch enables you to help monitor your watershed. Creeks and streams are a vital part of watersheds; they provide water to drink and sustain plant and animal life. However, they can also be a pathway for pollution to spread, and they are often too numerous for water boards to monitor without help."

"Materials scientists and electrochemists the world over are joining forces to create new types of batteries that perform better and last longer, are more reliable and demand less of the environment. The latest in a line of promising developments plugs into the properties of certain plants, crops and biological wastes."

Permacities came from the idea of creating social media games like FarmVille that instead of just wasting your money, actually taught you how to farm or kept you up to date with the movement.  A coworker of mine once commented on eco-utopian schemes and said, "Well, but what are they going to do about Los Angeles?" Permacities showcases things people are doing right now to upcycle existing environments into ecocities and ecovillages. The game was formerly known as Ecocity Now. We've changed the name to avoid confusion with other games and also to bring attention to permaculture principles of small scale interventions, working with nature, and focusing on both human and ecological needs. 

"Financial services firm Morgan Stanley predicts that up to a million Australian households could adopt home battery storage in the next four years. And, according to the Alternative Technology Association's (ATA) 2015 Household Battery Analysis, grid-connected solar and battery storage systems are likely to become economically attractive for most households by 2020. But there are some situations which may make it a good option before then. We've talked to the experts and combed the research to help you navigate your way into the energy revolution."

Investment in renewable energy infrastructure is outstripping that for fossil fuels. Investment was equal in 2008, but the balance has swung since. During 2011, globally, $40 billion was invested in fossil fuels. $260 billion was invested in renewables.  In the past year the price of photo voltaic cells has dropped by 50%. Peter Newman describes the growth of investment in renewable as exponential. He says we are living through one of the most dramatic periods in history as fossil fuels are being phased out.

Solar subsidies cost German consumers billions of dollars a year and are widely regarded as inefficient. Even environmentalists are concerned that Berlin's focus on solar comes at the detriment of other renewables. But the solar industry has a powerful lobby, and politicians have proven powerless to resist.

Climate change has altered the behaviour and interactions of many plants and animals, including when fish migrate and plants flower. But evidence has been lacking that such shifts have a genetic basis. Organisms often deal with environmental pressures by altering traits through a process known as phenotypic plasticity, which does not require genetic changes. But many organisms will need to evolve genetic adaptations to climate change to survive, and seasonal traits such as the timing of migration are those most likely to evolve as they are genetically heritable.

"The greening of American energy is both real and profound. But there's a flip side to this American success story. Even as our nation is pivoting toward a more sustainable energy future, America's oil and coal corporations are racing to position the country as the planet's dirty-energy dealer - supplying the developing world with cut-rate, high-polluting, climate-damaging fuels. Much like tobacco companies did in the 1990s - when new taxes, regulations and rising consumer awareness undercut domestic demand - Big Carbon is turning to lucrative new markets in booming Asian economies where regulations are looser. Worse, the White House has quietly championed this dirty-energy trade."

"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."
