• Offshore nuclear power plant safer against terrorists

    Building nuclear power stations underwater could help protect them from terrorist attacks, according to a French company hoping to do just that; the plant would sit on the seafloor at a depth of 60 meters to 100 meters, a few kilometers off shore; the design would make the plant resistant to tsunamis, earthquakes, or floods, and its underwater position makes it less vulnerable to terrorist attacks

  • Marines use solar power in Afghanistan to help fuel the fight

    Marines at Forward Operating Base Jackson in the Sangin valley of Helmand Province are using solar energy generators to stretch fuel supplies and save lives; with over 100 British troops killed there, Sangin valley is one of Afghanistan’s deadliest areas; since the implementation of portable solar energy generators, fuel consumption has decreased from twenty gallons to less than three gallons a day; delivering fuel is incredibly dangerous as fuel convoys are often ambushed or hit by IEDs

  • U.S. lacks infrastructure to increase use of ethanol fuel

    Scientists at Purdue University say the United States lacks the infrastructure to meet the federal Renewable Fuel Standard with ethanol; researchers say the United States has hit the “blending wall” and lacks the ability to consume more ethanol than what is currently produced; less than 3 percent of vehicles on the road are equipped to handle ethanol fuels and there are only 2,000 pumps; the federal Renewable Fuel Standard requires nearly three times as much renewable fuel to be produced per year by 2022

  • Army seeks to go off the grid at Fort Bliss

    At Fort Bliss Army commanders seek to power the base using renewable power sources by 2015; plans include using solar, wind, geothermal, and biomass; military bases around the country are increasingly looking at renewable energy to reduce their carbon footprint and avoid disruption in the event of a terrorist attack

  • Pentagon prohibited from purchasing Chinese solar panels

    Obama signs military appropriations bill that prohibits the Pentagon from purchasing Chinese solar panels; the “Buy American” provision is part of a larger trade dispute with China over subsidies; the Pentagon is investing heavily in solar to reduce its energy consumption and increase fighting effectiveness; the bill is likely to raise costs for the military

  • China says it has mastered the process of reprocessing nuclear fuel

    One way to extend to energy productivity of nuclear fuel is to reprocess it after it has been used; reprocessing nuclear fuel costs significantly more than using it once and storing it as waste; it is also controversial because extracted plutonium can be used in nuclear weapons; China has just announced that it has mastered the technology for reprocessing fuel from nuclear power plants, potentially boosting the supplies of carbon-free electricity to keep the country’s economy booming

  • The best place for a wind turbine: 30,000 feet above ground

    At altitude of 2,000 feet (610 meters), wind velocity is two to three times greater than at ground level; since power production goes up with the cube of that wind velocity, this means that at 2,000 feet above ground, wind produces 8 to 27 times the power produced by wind at ground level; if we send turbines farther aloft, into the 150 mph (240 kph) jet stream at 30,000 feet (9,150 meters), than power production grows from 500 watts per meter for ground-based wind turbines to about 20,000, 40,000 watts per square meter; this is very high energy density — and NASA is examining the project’s feasibility

  • Safety concerns remain about Westinghouse AP1000 reactor design

    The United States and the United Kingdom are yet to approve the latest reactor design from Westinghouse; regulators in both countries are not convinced that the reactor can effectively withstand man-made or natural disasters; these concerns notwithstanding, China is pushing forward with an ambitious nuclear energy program which will see sixty AP1000 reactors built by 2010; the scope and pace of the Chinese program, and the fact that at its core is a reactor with possible design weaknesses, are a cause of more concerns

  • Desalinating water, producing hydrogen, treating wastewater -- simultaneously

    Fresh water and reusable energy: humans are on a constant hunt for a sustainable supply of both; trouble is, water purification requires a lot of energy, while utility companies need large amounts of water for energy production; researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer

  • Fusion power nears

    The long-sought goal of a practical fusion-power reactor has inched closer to reality with new experiments from MIT’s experimental Alcator C-Mod reactor, the highest-performance university-based fusion device in the world; MIT advance helps remove contaminants that slow fusion reactions

  • Declining energy quality root cause of current recession

    A new concept — the Energy Intensity Ratio (EIR) — measures how much profit is obtained by energy consumers relative to energy producers; the higher the EIR, the more economic value consumers (including businesses, governments and people) get from their energy; to get the U.S. economy growing again, Americans will have to increase the U.S. EIR by producing and using energy more efficiently

  • World running out of cheap coal

    Most estimates of coal reserves suggest there is plenty to last at least a couple of hundred years, and a new report does not dispute this; the report says, rather, that using this coal will become progressively more expensive as the world is running out of coal that can be easily and cheaply recovered

  • Militants kidnap 7 from Nigerian Exxon platform

    After the 9/11 attacks, Bin Laden boasted that he used an operation which cost al Qaeda $500,000 to finance to inflict a $500 billion damage on the U.S. economy; this was not a mere boast: experts say it was an indication that econo-jihad was an integral part of al Qaeda’s strategy to weaken and defeat the West; the recent BP disaster offered an example of one tactics terrorists may pursue in order to inflict serious economic and environmental damage on the United States and other countries: attack off-shore oil rigs: these rigs are utterly vulnerable to attack, and the damage such an attack can do is considerable; in Nigeria, a militant organization is already attacking oil rigs — if, for now, only to kidnap rig workers in order to blackmail their employers for money and political concessions; the ease with which such attacks are carried out should give all of us a pause

  • Norway looking to osmotic power generation

    Water-based energy generation conjures up pictures of towering hydro-electric dams, submerged tidal turbines, and bobbing wave-energy converters; the energy embodied in moving water — which all of these technologies exploit — is one way to make electricity from the sea, but it is not the only one; in Scandinavia, a pilot power station is demonstrating that another of the sea’s defining characteristics, saltiness, could also be harnessed to provide electricity

  • Sea-based energy could supply 50% of Europe's needs by 2050

    By 2050 Europe could get up to 50 percent of its electricity needs from renewable marine sources; marine renewable energies include harnessing the power of offshore wind, waves, tides, and ocean currents as well as exploiting salinity and temperature gradients and using algae for biofuel production
