• Does the public trust what scientists say?

    If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm. >> Read the Full Article
  • Renewable energy capacity increases, nuclear declines

    Advocates of nuclear energy have long been predicting its renaissance, yet this mode of producing electricity has been stalled for years. Renewable energy, by contrast, continues to expand rapidly, even if it still has a long way to go to catch up with fossil fuel power plants, writes Worldwatch Institute Senior Researcher Michael Renner in the Institute’s latest Vital Signs Online analysis (bit.ly/NuclearRE). Nuclear energy’s share of global power production has declined steadily from a peak of 17.6 percent in 1996 to 10.8 percent in 2013. Renewables increased their share from 18.7 percent in 2000 to 22.7 percent in 2012. >> Read the Full Article
  • It's important to ventilate if you are cooking with gas!

    Cooking with gas is preferred by many cooks to alternatives. The popularity of "professional" stoves and cooktops with high-output burners makes cooking more fun perhaps, but those high-output burners also put out more contaminants. It is important to recognize this and to properly ventilate the cooking area with a hood that vents to the outside, or even a fan through the kitchen wall, or even a window. A new study by Oregon State University recommends that parents with children at home should use ventilation when cooking with a gas stove, after a new study showed an association between gas kitchen stove ventilation and asthma, asthma symptoms and chronic bronchitis. "In homes where a gas stove was used without venting, the prevalence of asthma and wheezing is higher than in homes where a gas stove was used with ventilation," said Ellen Smit, an associate professor in the College of Public Health and Human Sciences at OSU and one of the study’s authors. “Parents of all children should use ventilation while using a gas stove." >> Read the Full Article
  • Carbon Capture Technology and Climate Action

    Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels. For more than 40 years, companies have been drilling for carbon dioxide in southwestern Colorado. Time and geology had conspired to trap an enormous bubble of CO2 that drillers tapped, and a pipeline was built to carry the greenhouse gas all the way to the oil fields of west Texas. When scoured with the CO2, these aged wells gush forth more oil, and much of the CO2 stays permanently trapped in its new home underneath Texas. >> Read the Full Article
  • Burlington, Vermont - Now 100% Powered by Renewable Energy

    Burlington, Vermont, already considered to be one of the United States's most environmentally progressive cities, has added another line to its impressive green resume. Just recently, the city finalized its transition to relying 100% on renewable resources for its energy. Burlington is Vermont's large city, though that in itself is no big feat – the city has a population of just 42,000. Then again, very few communities of even this size have managed to disassociate themselves from fossil fuels. In order to adequately tackle climate change, cities – big and small – need to prioritize finding and utilizing alternative energy solutions. Burlington had expressed a desire to commit to 100% renewable energy for more than a decade, but it became a real possibility when analysts discovered that it was not only a smart environmental choice, but financially viable, too. In the long run, both the city and residents will not be paying more for clean energy than they were when buying fossil fuels. >> Read the Full Article
  • Electric vehicles getting even "Greener"

    Sixty percent of Americans now live in regions where electric vehicles (EVs) produce fewer heat-trapping global warming emissions per mile than the most efficient hybrids, according to an updated analysis from the Union of Concerned Scientists (UCS). In 2012, that number was just 45 percent. "Electric vehicles are doing more and more to fulfill their technological promise," said Don Anair, research director for UCS's Clean Vehicles Program. "If we want to reduce transportation pollution and oil use, a big part of the answer is to be like Bob Dylan and go electric." >> Read the Full Article
  • Japan: 'solar islands' replace nuclear power

    As Japan seeks to end reliance on nuclear power, one of the answers is floating 'solar islands', writes Jon Major. A 70MW solar island opened last year, and two additional plants have just been announced. Two companies in Japan recently announced they are to begin building two large solar power islands that will float on reservoirs. >> Read the Full Article
  • Disc or Download: A Virtual Energy-Savings Debate

    One of the best ways to spark an energy revolution is through the younger generation – and nothing quite speaks their language like video games. But this issue has less to do with the content of these addictive games and more with how the younger generation consumes them. Fantasy and adventure, sci-fi and first-person shooters, strategy and racing – video games today comes in all types of genres with thousands of add-ons and customizable features to make each story a virtual reality. And with all of these choices comes two more: buy a copy of the video game on a disc or download the video game straight from the console? >> Read the Full Article
  • Petrol vs. Diesel

    Climate change has made us question the things that we do, from buying food and using energy to riding planes and driving cars. One of the top questions surrounding climate change is this: Which fuel type is more environmentally friendly, petrol or diesel? Common knowledge would make us reply "diesel" right away, as engines running on diesel emit less carbon dioxide or CO2, and less CO2 is better to decrease the amount of greenhouse gases in the atmosphere. However, being eco-friendly isn't as simple as emitting less CO2. Diesel-powered vehicles may emit 20% less CO2 per kilometre travelled, but they may be more harmful for local pollution due to the tiny particles that are released by diesel engines into the atmosphere. The question really isn't which fuel or engine type is more environmentally friendly, as no form of engine that uses fossil fuels will ever become good for the environment. Rather, we should look at which has the capacity to inflict the least amount of damage to the environment. >> Read the Full Article
  • Hot and Cold Freezers

    The freezers being tested in Central Park operate free of electricity — vendors can even charge their own mobile devices by plugging them into outlets attached to the freezer units. It seems fitting that Unilever, the world's largest producer of ice cream, is rolling out the world's first solar freezers in Central Park to keep those Popsicles, Good Humor or Magnum-brand bars cold while at the same time putting no strain on the environment. >> Read the Full Article
