Much ado and attention has been paid to the pollutants emmitted from the tail pipes of cars and trucks in recent years, both here in the U.S. and across the pond in Europe. With an estimated 250 million passenger vehicles in the U.S. alone, it would seem that cars would be a major contributor to pollution and air quality issues here and abroad. But newly released data from Europe suggests that a single container ship may cause as much pollution as 50 million cars and release as much as 5,000 tons of sulfur oxide into the air annually. And there are 90,000 such ships of varying sizes across the world at any one time.

The Environmental Protection Agency seems on the brink of issuing a new regulation that would make it easier for power plants to operate longer hours - and emit more pollution. Under the proposed rule, power plants would be able to measure their rate of emissions on an hourly basis instead of their annual total output. As long as the hourly emissions stay at or below the plant's established maximum, the plant would be treated as if it were operating cleanly - even if its total annual emissions increased as plant managers stepped up output. Under the current policy, power plants that seek to operate longer must install pollution-control equipment. The proposed rule, expected to be finalized in the next two weeks, would increase the life span of older power plants without owners having to install costly new pollution-control equipment.

Light pollution in the broad sense refers to any nighttime artificial light that shines where it's not needed. This nocturnal brightness can disorient humans and a host of other animals, confounding eyes and biological rhythms that evolved in a world without such light. One way stray rays pollute is sky glow, the scattering of light by clouds and atmospheric particles that makes it difficult to see stars and other features of the night sky-an increasing problem. These maps show the global extent of sky glow. More than just snapshots of the Earth at night, they account for the light-scattering effects of clouds and dust, and show how bright the sky is above a given point on the ground-revealing that most of the world's population lives under night skies fuzzy with the haze of reflected light.

Six weeks before leaving office, the Bush administration is giving up on an effort to ease restrictions on pollution from coal-burning power plants, a key plank of its original energy agenda and one that put the president at odds with environmentalists his entire eight years in the White House. President George W. Bush had hoped to make both changes to air pollution regulations final before leaving office on Jan. 20. In the midst of a coal-fired power plant construction boom, the rules would have made it easier for energy companies to expand existing facilities and to erect new power plants in areas of the country that meet air quality standards.

New research from Stanford University ranks wind power as the most promising alternative source of energy. Titled Review of solutions to global warming, air pollution, and energy security, the report from civil and environmental engineering professor Mark Z. Jacobson ranks the world's energy options -- putting wind, concentrated solar and geothermal at the top of the list, and nuclear power and coal with carbon capture and sequestration in a tie for dead last. ... From his findings, Jacobson is able to suggest that the U.S. government invest money and create jobs around the development of wind, solar and geothermal: "There is a lot of talk among politicians that we need a massive jobs program to pull the economy out of the current recession," Jacobson said. "Well, putting people to work building wind turbines, solar plants, geothermal plants, electric vehicles and transmission lines would not only create jobs but would also reduce costs due to health care, crop damage and climate damage from current vehicle and electric power pollution, as well as provide the world with a truly unlimited supply of clean power."

15 states appear to have three or more Tennessee-like unlined "Surface Impoundment" sites For toxic coal-fired power plant waste. (WASHINGTON, D.C.) - Could another major coal disaster happen at one of the many Tennessee-like power plant coal pollution dumping sites across the United States? How much toxic arsenic, lead and other heavy metals that endanger drinking water are being dumped into those unlined "surface impoundment" sites each year? How did federal regulation of coal pollution break down to allow these threats to exist … and what needs to happen if the public and environment are to be protected against future Tennessee-like disasters, as well as the "slow-motion" leaching of toxic metals into drinking water, rivers and streams?

"The future of a US climate law is hanging in the balance in Congress as lawmakers gear up for crucial midterm elections amid a persistent economic slump, experts say. Further reducing the impetus, UN climate talks in Copenhagen ended last month with a non-binding agreement to limit warming to 3.6 degrees Fahrenheit (two Celsius) that did not set binding targets to reduce the emissions of gases scientists say are heating up the world's atmosphere to dangerous levels. Among the thorniest problems facing a possible US law is striking an agreement on creating a "cap-and-trade" market for greenhouse gases that would force heavy polluters to buy credits from companies that pollute less, creating financial incentives to fight global warming."

No fish can escape mercury pollution. That's the take-home message from a federal study of mercury contamination released Wednesday that tested fish from nearly 300 streams across the country. The toxic substance was found in every fish sampled, a finding that underscores how widespread mercury pollution has become. But while all fish had traces of contamination, only about a quarter had mercury levels exceeding what the Environmental Protection Agency says is safe for people eating average amounts of fish. The study by the U.S. Geological Survey is the most comprehensive look to date at mercury in the nation's streams. From 1998 to 2005, scientists collected and tested more than a thousand fish, including bass, trout and catfish, from 291 streams nationwide.

But even on a clear night, many would-be astronomers are missing out on this rare celestial scowl, instead being treated to a dull haze punctuated by only the nearest or brightest objects, Jupiter not being one of them. So pervasive is this murky veil that the National Park Service estimates that two-thirds of Americans cannot see the Milky Way from their homes. Had Carl Sagan spent his whole life in a contemporary US city, he'd no doubt have marveled at the dozens and dozens of lights dotting the firmament. The cause of this stellar pall? Carelessly designed streetlamp fixtures, signs, and office lighting controls that pointlessly illuminate the sky, blocking our view of the universe.

The Air Car caused a huge stir when we reported last year that Tata Motors would begin producing it in India. Now the little gas-free ride that could is headed Stateside in a big-time way. Zero Pollution Motors (ZPM) confirmed to PopularMechanics.com on Thursday that it expects to produce the world's first air-powered car for the United States by late 2009 or early 2010. As the U.S. licensee for Luxembourg-based MDI, which developed the Air Car as a compression-based alternative to the internal combustion engine, ZPM has attained rights to build the first of several modular plants, which are likely to begin manufacturing in the Northeast and grow for regional production around the country, at a clip of up to 10,000 Air Cars per year.

Big Stone II's demise is not a bad sign for wind, it is the opposite. Now is the opportunity to move ahead to the next economy, not to worry about what we lost with a big polluter. Let's give this gift to our future generations - a better future. Take a deep breath and let's take a look at what the next energy economy will look like. We will move to an entirely non-fossil fuel economy based on solar and wind. We will have 89,000 solar photovoltaic and concentrated solar panels, 1.7 million rooftop PV systems to reduce combustion on most of our houses and perhaps solar water as well. We will have 3.8 million wind turbines worldwide taking up a total area smaller than the size of Manhattan. When the wind doesn't blow in South Dakota, it blows in North Dakota, or Nebraska, or the steppes of Russia. Distributed wind is where we should be headed. And hydro-power can "firm" intermittent wind - we have plenty of dams on the Missouri.

Generating electricity by burning coal is responsible for about half of an estimated $120 billion in yearly costs from early deaths and health damages to thousands of Americans from the use of fossil fuels, a federal advisory group said Monday. A one-year study by the National Research Council looked at many costs of energy production and the use of fossil fuels that aren't reflected in the price of energy. The $120 billion sum was the cost to human health from U.S. electricity production, transportation and heating in 2005, the latest year with full data. The report also looks at other hidden costs from climate change, hazardous air pollutants such as mercury, harm to ecosystems and risks to national security, but it doesn't put a dollar value on them.

With coal being too dirty and wind farms and nuclear power plants arriving late, it seems the world is left with a stark choice: keep on polluting or turn out the lights. Unless, that is, someone comes up with an alternative. Energy executive Rune Bjornson thinks he has the answer. "Natural gas, more than any other fuel, is an option we have here and now," he tells the BBC in an interview. And, he adds, there is plenty of it around - unlike scarcer resources such as oil and coal.

Three environmental groups want the state to throw out a permit it just issued that would allow TVA to dump water tainted with mercury, selenium, arsenic, and other chemicals from the Kingston coal-fired power plant into the Clinch River. The Clinch, which lies below the power plant, has already received ash moving down the Emory River from the massive ash spill last December. Earthjustice, Environmental Integrity Project, and the Sierra Club on Thursday filed an appeal of a water discharge permit that the Tennessee Department of Environment & Conservation issued four weeks ago. They say letting TVA pipe one million gallons of wastewater a day from a pond with gypsum into the river isn't wise. The material will be a byproduct of the plant's new air pollution system.

How the world is fed and fueled will in large part define development in the 21st century as one that is increasingly sustainable or a dead end for billions of people. A new and hard-hitting report concludes that dramatically reforming, re-thinking and redesigning two sectors -- energy and agriculture -- could generate significant environmental, social and economic returns. Current patterns of production and consumption of both fossil fuels and food are draining freshwater supplies; triggering losses of economically-important ecosystems such as forests; intensifying disease and death rates and raising levels of pollution to unsustainable levels."

George Bush is behaving like a furious defaulter whose home is about to be repossessed. Smashing the porcelain, ripping the doors off their hinges, he is determined that there will be nothing worth owning by the time the bastards kick him out. His midnight regulations, opening the United States's wilderness to logging and mining, trashing pollution controls, tearing up conservation laws, will do almost as much damage in the last 60 days of his presidency as he achieved in the foregoing 3 000.

Fellow Americans we must stop investing in roads, highways and parking lots. The automobile must go the way of the horse as an antiquated way of getting around. Find a better way now, before desperation forces us to do so. Let's lead the world to a better future, not follow the status quo into pollution and sprawl. I worked in the oil and gas exploration and production industry for 25 years. Few citizens fully understand the scope of the current oil and gas production infrastructure in this country. There are tens, if not hundreds of thousands of oil and gas wells across this country all pumping oil and gas continuously around the clock. Pipelines criss-cross the sea bottom and the landscape carrying millions of gallons of fuel, yet the domestic production meets only a fraction of the current demand for the products. No amount of domestic drilling can meet the country's demand. This world must change its energy infrastructure and transportation systems, and America should lead the way.

Here is a list of energy news items that the WattzOn team found most interesting in 2008: * CO2 is officially a pollutant (maybe) - In a ruling by the Environmental Appeals Board (a panel within the EPA), it was decided that the EPA has no valid reason to not limit CO2 emissions from coal plants. Confusingly, the EPA has recently overruled itself by stating that officials cannot consider greenhouse gas outputs in judging applications to build new coal-fired power plants. So, it's back up in the "air." * We need to be at 350 PPM of CO2 - James Hansen of Columbia University, and NASA's head of the Goddard Institute for Space Studies, published a landmark paper: "Target Atmospheric CO2: Where Should Humanity Aim?" in which he argues for an atmospheric CO2 concentration of 350 parts per million (PPM) for humanity to be safe on this planet. As some background, pre-industrial Earth had a CO2 concentration of around 275 PPM, and for years policy makers have set a target regulatory goal of 550 PM - twice that number. More recently, 450 PPM has been proposed as a better goal by the EU and a few others. Unfortunately, recent evidence has shown that the Arctic sea is melting at an alarming rate and a giant ice sheet in Greenland is starting to slide into the ocean. This is the reality with the world today at 383 PPM. Hansen points out that this means we set overly lax targets and proposes the 350 PPM goal with tons of paleo-climatic data to back him up. We need to bring the CO2 in our atmosphere back down to this concentration. * Energy scientists primed to enter government - US President-Elect Obama has nominated Steven Chu to be the Secretary of Energy, and named John Holdren as the Assistant to the President for Science and Technology / Director of the White House Office of Science and Technology Policy / Co-Chair of the President's Council of Advisors on Science and Technology. As the President-Elect puts it, "Today, more than

The California Air Resources Board (CARB) is today expected to adopt the most radical global warming plan in the U.S., and possibly the world. If passed, it will force individuals, as well as the state's utilities, refineries and large factories to fundamentally change the way they do business, and slash greenhouse gas emissions. The plan will outline for the first time how people and businesses will be required to meet the state's 2006 'Global Warming Solutions Act' and transform California into a global leader in the fight against climate change. The board will be in session all day to consider approval of the AB 32 Scoping Plan to Reduce GHG Emissions in California. Key aspects of the plan include: * The creation of a carbon-credit 'cap and trade' market designed to give the state's major polluters cheaper ways to cut emissions; * A Low Carbon Fuel standard; * Stringent transport related greenhouse gas targets; * A target of generating 33% of the states's electricity from renewable energy by 2020; * Ambitious vehicle efficiency measures; * Implementation of a high speed rail system; * A radical green building strategy.
