• Renewable Energy Closes "The Gap"

    The Renewables Energy Policy Network for the 21st Century - shows that renewables are now firmly established as competitive, mainstream sources of energy in many countries around the world, closing the gap between the energy haves- and have-nots

  • Better combustion for power generation

    In the United States, the use of natural gas for electricity generation continues to grow. The driving forces behind this development? A boom in domestic natural gas production, historically low prices, and increased scrutiny over fossil fuels' carbon emissions.

  • A Different Look at Energy Harvesting Roadways

    Over fifty percent of the United States energy comes from coal and petroleum based fuels. Powering a nation in which the average person uses the amount of energy in 15,370 lbs of coal or 165,033 sticks of dynamite in a year is not sustainable. When thinking of a solution, the well-known renewable energy source that most likely comes to mind is solar power.

    Solar panels are an impervious surface. Impervious surfaces already take up 32,868.61 square miles of roads, parking lots, driveways, and more. These surfaces displace rainwater to surrounding areas and have great impacts on the water table and soil quality. Utilizing already cleared land rather than clearing more would be beneficial to the environment, as solar fields require large amounts of cleared land.

  • The Great Green Wall of Africa

    Though a border wall with Mexico is currently a matter of serious discussion in the United States, the aim of which is to prevent the physical movement of people (with few other apparent “benefits”), some walls can actually bring together and preserve communities, rather than divide them.

    In only five years, the UN says, around 60 million Africans may be displaced as their land ceases to be arable, a potential humanitarian disaster the scale of which would be unprecedented. This would be devastating to a huge portion of the African continent not only ecologically and economically but socially as well.

    That’s where Africa’s ingenious Great Green Wall comes in.

    Experts at the United Nations say without action, desertification may claim two-thirds of Africa’s farmlands in under a decade. The Great Green Wall, however, was conceived as a wide-reaching strategy to halt Northern Africa’s rapidly advancing Sahara Desert.

    The Great Green Wall, once complete, will stretch an incredible 4,400 miles from Senegal in West Africa to the East African nation of Djibouti. Instead of bricks and mortar, the wall will be made of trees and other vegetation, including plants that can be eaten or used to create medicine.

  • Why aren't hybrid car owners showing more loyalty to hybrids?

    Hybrid cars have come a long way since the first frumpy Toyota Prius debuted in Japan almost 20 years ago. The same can be said for electric cars since GM rolled out its EV1 in the late 1990s, only to backtrack, repossess and destroy all of them, infuriating its fans in the process. There are now dozens of hybrid models, and they enjoyed a surge in saleswhen gasoline prices spiked in 2007 and again in 2012. But more recently, their sales overall have been on the decline. Meanwhile electric vehicles are becoming more sophisticated, are improving their range and have seen sales on the uptick while the automakers have become more competitive in their advertising.

    As expected, hybrid cars’ sluggish sales numbers have much to do with the fact that oil prices have been in a two-year slump while conventional gasoline engines keep getting cleaner and more fuel efficient. When hybrids started becoming more popular a decade ago, it was often assumed that when it came time for a new upgrade, owners would stay loyal and trade in one hybrid car for another.

  • Australian river on fire with fracked coal seam gas

    So much methane is bubbling into a river surrounded by hundreds of fracking wells that it's a fire hazard! Local campaigners blame the coal seam gas industry for the gas releases which are spreading along Queensland's river Condamine and gaining in intensity.

    So much methane gas is now bubbling up through the Condamine River in Queensland, Australia that it exploded with fire and held a large flame.

    Gas seeping into the river began shortly after coal seam gas operations started nearby and is growing in volume and the stretch of river affected is expanding in length.

  • Study shows most US roofs can support a solar system

    Most U.S. rooftops in good repair can take the weight of solar photovoltaic (PV) systems. That’s the conclusion of a three-year study by a research team led by Sandia National Laboratories.

    “There is a misperception in the building industry that existing residential rooftops lack the strength to carry the weight load of rooftop solar photovoltaic installations,” said Sandia structural engineer Steve Dwyer. “Most existing well-built wooden rooftops can support PV system loads.”

    Sandia took on the job of analyzing rooftop structural strength to address concerns raised in the U.S. Department of Energy’s (DOE) Solar America Cities program. The agency named 25 cities to promote adoption of solar technology at a comprehensive, local level through photovoltaics.

  • Scotland shuts down its last coal-fired electric power plant

    After nearly 50 years of service, Scotland’s last coal-fired power plant — Longannet Power Station — has finally gone offline, putting an end to over 100 years of burning coal for electricity.

    It’s an important moment for Scottish Power, which looks ahead to clean power initiatives with the goal of going all-renewable by 2020,

    But it’s also a very symbolic action for the world. Hopefully other nations will follow suit, creating a domino effect as country by country eliminates its coal plants — like the one above — in favor of renewable alternatives.

  • Severe water stress likely in Asia by 2050

    Economic and population growth on top of climate change could lead to serious water shortages across a broad swath of Asia by the year 2050, a newly published study by MIT scientists has found.

    The study deploys detailed modeling to produce what the researchers believe is a full range of scenarios involving water availability and use in the future. In the paper, the scientists conclude there is a “high risk of severe water stress” in much of an area that is home to roughly half the world’s population.

  • Human impact on Earth's global energy

    The impact humans have made on Earth in terms of how we produce and consume resources has formed a 'striking new pattern' in the planet's global energy flow, according to researchers from the University of Leicester.

    The research suggests that Earth is now characterised by a geologically unprecedented pattern of global energy flow that is pervasively influenced by humans -- and which is necessary for maintaining the complexity of modern human societies.

    The new study, published in the journal Earth's Future, is led by Professors Mark Williams and Jan Zalasiewicz of the University of Leicester's Department of Geology working with an international team of scholars.
