Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

UAE, Australia, USA and Canada top list of polluters

Most Unethical Countries Worst Polluters

UAE, Australia, USA, Canada, Netherlands and Saudi Arabia are the worst CO2 polluters: Report

The United Arab Emirates, Australia, the United States and Canada have the worst overall records for emitting carbon, based on their  current and historic emissions, says a report.


A new study, which rates 183 countries on their CO2 emissions from energy use, has identified United Arab Emirates (UAE), Australia, USA, Canada, Netherlands and Saudi Arabia as the world’s six worst polluters in relation to CO2 pollution.

UAE (1), Australia (2), USA (3), Canada (4), Netherlands (5) and Saudi Arabia (6) are the only countries rated by the report as ‘extreme risk’ because of their high CO2 emissions from energy consumption.

“The poor performance of UAE and Saudi Arabia is reflective of a near 100% reliance on fossil fuels and their use of energy intensive desalination plants to produce drinking water. Saudi Arabia was the 11th highest global emitter in 2008 with 466 MtCO2. However, the desalination process that produces 70% of the country’s drinking water accounts for 50% of CO2 emissions. UAE dropped 15 places from last year to take the bottom spot due to a huge 25% jump in its overall carbon output between 2006 and 2008 and a 20% rise in per capita emissions.  Maplecroft recognises that desalination is a positive way to address water security but high emissions underline the need to find more energy efficient innovations.” The report said.

EU Energy Strategy Beats US Energy Tragedy

Posted by feww on July 15, 2008

As the 27-nation EU bloc declare their support for eco-friendly products and technology, and propose to cut energy consumption, the US opts for offshore drilling.

France’s Ecology Minister told EU energy ministers in Paris last week that energy efficiency has become the “keystone” in EU energy strategy.

The EU Commission’s “action plan on sustainable industrial policy and on sustainable consumption and production” is part of that startegy.

“There will be proposals on green public procurement, as well as widening the scope of the existing directive on eco-design to help improve the energy efficiency of buildings, and the scope of rules on eco-labeling will be widened,” a Commission spokesperson said.

The EU bloc is 63 percent more populated than the US, but uses less than a half of the per capita energy and produces 46 percent less CO2. [Sources: EIA, US Census Bureau, BP]

So, which one of the two “super states” has a smarter energy strategy, EU or the US?

Hint: You don’t need a Ouija board to work that out!

NO More Coal-fired Power Plants Here!

Too Little, Too Late?

Longleaf Energy Resources Leaves Court with a Red-Coal Face

A Georgia state court invalidated a permit to build a 1,200-megawatt coal-fired power plant in Early county, citing the developers’ failure to limit emissions of carbon dioxide. A Fulton County Superior Court Judge, Thelma Wyatt Cummings Moore [kudos to judge Moore], reversed a right to pollute permit [aka, air permit] issued earlier this year by the Georgia Department of Natural Resources to Longleaf Energy Resources.

Southern Company’s Plant Bowen in Cartersville, Georgia is seen in this aerial photograph in Cartersville in this file photo taken September 4, 2007. One of the biggest coal-fired plants in the country, it generates about 3,300 megawatts of electricity from four coal-fired boilers. (Chris Baltimore/Reuters; caption: abc News.

The judge citied a 2007 U.S. Thelma Wyatt Cummings Moore decision in which carbon dioxide was ruled to be a pollutant under the existing Clean Air Act and that the U.S. Environmental Protection Agency has the authority to regulate carbon dioxide emissions.

How much coal would it take to light a 100W light bulb for one year?

A 100-Watt light bulb consumes about 876 kWh of electricity in one year (100 W × 24 h/day × 365 days = 876,000 Wh = 876 kWh).

Energy density

The energy density of coal, expressed in kilowatt-hours per kilogram, is about 6.67 kWh/kg. The typical thermodynamic efficiency of coal power plants is about 30%. That means only 30% of the coal burned up turns into electricity, with the rest is normally wasted as heat. Coal power plants generate approximately 2.0 kWh per kg of burned coal.

876 kWh ÷ 2kWh/kg = 438 kg of coal

However, the above amount does not take into account a further 5–10% transmission and distribution losses caused by resistance and heating in the power lines AND the initial energy used to mine the coal and ship it to the power plant, which could be equivalent to 10-15% of the total coal consumed.

438 kg ÷ 80% = 547.5 kg of coal {Total amount of coal consumed to light a 100W bulb for one full year!}

How Much Carbon Dioxide?

Carbon dioxide (CO2) forms during coal combustion when one atom of carbon (C) combines with two atoms of oxygen (O2). Carbon has an atomic weight of is 12, and oxygen 16, making the atomic weight of carbon dioxide 44. A kg of coal with a carbon content of 78 percent and a heating value of 32 MJ/kg emits about 2.86 of carbon dioxide. (Source: Carbon Dioxide Emission Factors for Coal)

547.5 kg of coal x 2.86 = 1,566 kg of CO2 {The total amount of CO2 produced.}

[Note: other nasty byproducts include sulfur, which reacts with oxygen to produce SO2, which then combines with moisture in the air to produce acid rain, nitrogen oxides, NOx, and mercury, all of which are extremely harmful to air, water, soil, trees, marine animals and humans.]

Meanwhile, back in Crawford ranch …

White House officials, congressional staff revealed, refused to open e-mail from the U.S. Environmental Protection Agency, EPA, that said climate-warming greenhouse emissions threaten public health and welfare!

The EPA has also told members of Congress that the Defense Department is defying orders over cleaning up toxic pollution at three military bases at Fort Meade in Maryland, McGuire Air Force Base in New Jersey and Tyndall Air Force Base in Florida.
