In an article written for Huffington Post, Andrew Steer discusses how shale energy depends on water supply.

The shale gas revolution, which began nearly 10 years ago in the United States, is poised to spread across the globe. For many countries, shale gas could strengthen energy security while cutting emissions.
But unlocking this massive resource comes with a significant environmental risk: access to freshwater for drinking, agriculture, and industrial use.
Dozens of countries are deciding whether or not to develop their shale gas and tight oil resources in order to reduce emissions, create new jobs, and increase national energy supplies. However, extracting natural gas and tight oil from shale poses water risk.
We analyzed water stress levels in the 20 countries with the largest shale gas and tight oil resources, and found that 40 percent face high water stress.
As China pursues shale gas exploration and development, it could draw some lessons—both positive and negative—from the experience in the United States. Indeed, it is in both countries’ interest that their businesses and governments collaborate to ensure that when and where shale gas is developed, it is done responsibly.
In order to pursue shale gas development responsibly, three issues are emerging as potential hotspots for U.S.-China collaboration—environmentally smart development, energy security, and economy.
When President Obama addresses the nation later today, climate change is expected to be featured. The president recently said that one of his personal passions is “leaving a planet that is as spectacular as the one we inherited from our parents and our grandparents.” The next two years will determine if his administration can meet this standard.
Energy and consulting firm Wood Mackenzie, supported by data and analysis from WRI’s Aqueduct Water Risk Atlas, surveyed water risks among the world’s top energy-producing regions. They found that three energy sectors face particularly high water risks: shale gas in the United States, coal production and coal-fired power in China, and crude oil in the Middle East.

The U.S. Department of Energy made a big announcement late last week, green lighting the country’s second liquefied natural gas (LNG) export project. Many argue that natural gas exports will bring economic and geopolitical benefits for the United States--with Japanese and French companies coming on board as key partners in the proposed export station.
Indeed, natural gas can contribute to a lower-emissions trajectory--but only if it’s done right. With effective policies and standards in place, natural gas can help displace coal while complementing lower-carbon, renewable energy sources. But without these protections, U.S. LNG exports will likely lead to an increase in domestic greenhouse gas (GHG) emissions and, as discussed below, may have a negative effect on global climate change.
U.S. natural gas production is booming. According to the Energy Information Administration (EIA), production grew by 23 percent from 2007 to 2012. Now—with production projected to continue growing in the decades ahead—U.S. lawmakers and companies are considering exporting this resource internationally. But what are the climate implications of doing so?
This is a topic I sought to address in my testimony yesterday before the U.S. House of Representatives Energy and Commerce Subcommittee on Energy and Power. The hearing, “U.S. Energy Abundance: Exports and the Changing Global Energy Landscape,” examined both the opportunities and risks presented by exporting liquefied natural gas (LNG). I sought to emphasize a number of points that are often overlooked in this discussion; in particular, fugitive methane emissions and cost-effective options for reducing them.
Environmental Impacts of Natural Gas Production
While burning natural gas releases half the amount of carbon dioxide as coal, producing the fuel comes with considerable environmental risks (see: here, here, and here). We’re already seeing these risks play out domestically. In addition to habitat disruption and impacts on local air and water quality, one of the most significant implications of natural gas production is fugitive methane emissions.
The U.S. Environmental Protection Agency (EPA) recently released its annual greenhouse gas (GHG) inventory report. Using new data and information, the EPA lowered its estimate of fugitive methane emissions from natural gas development by 33 percent, from 10.3 million metric tons (MMT) in 2010 to 6.9 MMT in 2011. While such a reduction, if confirmed by measurement data, would undeniably be a welcome development, it doesn’t mean that the problem is solved.
Here are five big reasons we should care about fugitive methane emissions:
1) Emissions Are Still Too High.
Methane is a potent greenhouse gas and a key driver of global warming. Methane is 25 times stronger than carbon dioxide over a 100-year time period and 72 times stronger over a 20-year period. In fact, 6.9 MMt of methane is equivalent in impact to 172 MMt of CO2 over a 100-year time horizon. That’s greater than all the direct and indirect GHG emissions from iron and steel, cement, and aluminum manufacturing combined. Reducing methane emissions is an essential step toward reducing U.S. greenhouse gas emissions and slowing the rate of global warming.
