The Emergency Email & Wireless Network,

Scientists, climatologists and energy experts share a growing concern: the need for water in the production of energy, especially in regions that are experiencing serious drought. Generating power – whether it be from fossil fuels or renewable energy sources – requires large amounts of water. How are the nation’s energy producers are facing this challenge?

Water is also used to cool fuel rods at nuclear plants and to generate steam to power turbines. The biofuel industry needs water for irrigation, fermentation and the production of ethanol and biodiesel fuels.

Alexander Ochs, director of climate and energy at the Worldwatch Institute, says that adds up to a lot of water. “Per megawatt hour, coal uses 500 to 1000 gallons of water for the production of just one megawatt hour of electricity,” said Ochs. “If we look at all the plants combined in the U.S., all the thermo-electric plants [powered by steam] in the US in 2008 alone, they drew 60 billion to 170 billion gallons of water, per year.”

Without water, most types of energy could not be produced. Even renewable energy, like geothermal and solar, use water to cool equipment and to clean the collector panels. Those requirements have led California, Massachusetts and several Midwestern states to halt the operations of some power plants.

“Places like the Midwest where water is a very scarce resource already today, a number of power plants have actually been halted, and this is actually true for across the United States,” said Ochs. (…)

The USA on its way to Copenhagen – Perspectives for international climate policy

 online report, presentation  Comments Off on The USA on its way to Copenhagen – Perspectives for international climate policy
Jun 222009

More than 80 participants followed the invitation of the NABU and the Heinrich Böll Foundation on 15 June 2009 in Berlin to discuss with American and German experts key contributions on both sides of the Atlantic to tackle the global climate crisis. Another key point of interest was an assessment of the current state of negotiations of a new global climate pact on which the international community wants to agree at the UN climate conference in the end of this year in Copenhagen.

In the discussion, I emphasized the central Importance of new U.S. energy and climate legislation, the so-called Waxman-Markey Bill, which has already passed important hurdles in the House of Representatives and will be discussed in the Senate later this year – hopefully to be be adopted. Since 1990, U.S. greenhouse gas emissions have risen by about 16 percent. For the US to reduce its emissions by 20 percent compared to 2005 in 2020, as W-M envisions, will be a very remarkable challenge and an effort compatible to the cuurent evrsion of the EU climate and energy package. Critics often suggest that the absolute reductions in WM amount to only 4% compared to 1990. I pointed out, however, that these 4% only include the emission reductions in the  sectors covered by a future emissions trading scheme. Some estimates believe that the entire reduction effort in the US (including non-ETS-covered sectors and offsets) could amount to about -17% in 2020 compared to 1990. Accordingly, the U.S. would reduce its emissions by more than one third compared to total emissions expected in a business as-usual-scenario. Europe aims at reducing emissions by 20% compared to 1990 and has offered a -30% target if other parties commit to a similar level of ambition.

I also pointed to the fact that the American climate debate much more than the one in Europe is fixated on China, because of competitiveness concerns for the U.S. economy. In many cases, these concerns are distorting important facts and are therefore exaggerated. Only recently it has been noted that China already has very ambitious policies inplace to increase energy efficiency and the expansion of renewable energies despite no binding reduction targets under the Kyoto Protocol. I also discussed sectoral approaches as a way to provide additional incentives to abate emissions in energy-intensive industries. Panel guests: Prof. Dr. Miranda Schreurs, Research Center for Comparative Environmental Policy, Free University Berlin; Alexander Ochs, director of international climate policy, Center for Clean Air Policy, Washington DC; Dr. Karsten Sach, Deputy Director General for International Cooperation, Federal Ministry of Environment; Duncan Marsh, director of international climate policy, The Nature Conservancy; Carsten Wachholz, secretary for energy policy and climate protection, NABU.
