Greenpeace Hot Air Balloon Delivers Message - NO FUTURE IN COAL


Click here to read full article


Hunter Valley, Australia — Prime Minister Rudd wants to stop dangerous climate change and we want to give him the chance to show that all his talk is not just hot air. So, at dawn today, the Greenpeace hot air balloon delivered a message to Kevin in spectacular fashion: "Save the climate - No future in coal".

The balloon flew over two coal-fired power stations in the New South Wales Hunter Valley, launched by a team of Greenpeace staff and volunteers camped in the Hunter Valley. As the eyecatching aircraft flew above coal stacks, it attracted plenty of attention on the ground.


CCS enables COAL to have a future AND burn even MORE coal! OPPOSE CCS - too expensive, too risky, unproven!

Carbon sequestration frustration Burying carbon dioxide from coal-fired plants could increase other pollutants

Another reason why CCS does not make sense.......... it exists to keep Big Coal burning.

As pollution bad guys go, carbon dioxide may be the media darling, but trying to capture it and lock it away could allow other repeat offenders to go free.

Power plant emissions that cause acid rain, water pollution and destruction of the ozone layer may actually be made worse by capturing the CO2 and pumping it deep underground, a new study reported online and in an upcoming International Journal of Greenhouse Gas Control suggests.

This increase of other emissions is largely because collecting and burying CO2 — a process called carbon sequestration — requires additional energy, new equipment and new chemical reactions at the plants. And using current technology, meeting all of these requirements releases extra pollutants.

“Other studies mostly just look at one aspect, the carbon capture,” says study coauthor Joris Koornneef, an environmental scientist at Utrecht University in the Netherlands. “This is a first step in trying to quantify the [environmental] trade-offs.”

Captured CO2 must be compressed to about 100 times atmospheric pressure (which takes energy), transported to a suitable underground reservoir (which takes energy) and pumped into the ground (which takes energy). A coal-fired power plant that sequesters its CO2 must burn about 30 percent more coal than conventional plants to cover these energy needs. And that extra coal must first be mined (which has environmental effects) and transported to the plant (which takes fuel) — the list goes on and on.

Even with this extra burden, a CO2-burying plant emits between 71 and 78 percent less CO2 than a normal coal-fired plant for each unit of usable electricity produced, Koornneef and his colleagues report. But when the researchers factored in all the “cradle to grave” pollution of a CO2-burying plant, emissions of acid rain-causing gases like nitrogen oxides and sulfur oxides were up to 40 percent greater than the total cradle-to-grave emissions of a modern plant that doesn’t capture its CO2.

In response to passage of the "American Clean Energy and Security Act" by the House Energy and Commerce Committee


Joint statement by:

Greenpeace USA * Friends of the Earth * Public Citizen * Citizens Action Coalition of Indiana *Citizen Power * Center for Biological Diversity * TURN-The Utility Reform Network * Sustainable Energy & Economy Network * Green Delaware * Massachusetts Environmental Energy Alliance * Massachusetts Forest Watch * Coal Moratorium Now!

Washington-In response to passage of the "American Clean Energy and Security

Act" by the House Energy and Commerce Committee, a coalition of environmental, legal, consumer, and community advocacy groups released the following joint statement:

"While a week of debate failed to adequately strengthen protections for consumers, communities, and the climate in this bill, it erased all doubt of who will benefit most from it: Big Business. Despite the best efforts of Chairman Waxman, the decision-making process was co-opted by oil and coal lobbyists determined to sustain our addiction to dirty fossil fuels, even as the country stands ready to rebuild our economy and clean up the environment with real clean energy. The resulting bill reflects the triumph of politics over science, and the triumph of industry influence over the public interest.

"Regrettably, we cannot support this legislation unless and until it is substantially strengthened. The lives and livelihoods of 7 billion people worldwide will be affected by America 's response to the climate crisis. The response embodied in today's bill is not only inadequate it is counterproductive.

"As passed through the Energy & Commerce Committee, the American Clean

Energy and Security Act sets targets for reducing pollution that are far weaker than science says is necessary to avoid catastrophic climate change. The targets are far less ambitious than what is achievable with already existing technology. They are further undermined by massive loopholes that could allow the most polluting industries to avoid real emission reductions until 2027. Rather than provide relief and support to consumers, the bill showers polluting industries with hundreds of billions of dollars in free allowances and direct subsidies that will slow renewable energy development and lock in a new generation of dirty coal-fired power plants. At the same time, the bill would remove the President's authority to address global warming pollution using laws already on the books.

"The international community cannot solve global warming without real leadership from the United States . We urge the President to demonstrate that leadership by working with Congressional leaders to craft a real, science-based response to the challenge of global warming and by immediately exercising his substantial authority to regulate global warming emissions under existing laws."
