At first, some environmentalists saw the natural gas boom as a way to promote a relatively carbon-light “bridge fuel” that would take us from dirty coal to clean renewables. Then concerns surfaced that natural gas extraction was contaminating water and soil. And natural gas, it turns out, has its own greenhouse gas issues. Is increasing domestic natural gas production a smart way to transition from coal to renewables? Richard Ward of the UN Foundation’s Energy program says, Yes – with the proper oversight. Jennifer Krill, executive director of Earthworks, disagrees.

The scientific consensus is stark: Earth systems are dangerously close to tipping points which, once crossed, could ignite negative feedback loops and catastrophic climate change beyond human capacity to remedy. Because burning hydrocarbons is the cause, many environmentalists advocate a complete ban on carbon fuel sources in favor of renewables. This is compelling until we consider the numbers. The US uses about 100 quadrillion BTUs of energy a year and emits 6 billion tons of the world’s 30 billion tons of CO2. We use nearly 40 quads of oil for transportation and about 40 quads of energy for electric power. By contrast, our production from wind and solar is only 0.5 quads. To replace the 67 quads of oil, coal, and natural gas with wind and solar would take decades. In this time, the emissions from coal and oil would drive the planet over the brink.…more…

“Natural gas: the bridge to a clean energy future!” Nice sound bite. But the reality is that natural gas is nothing but a bridge to more natural gas – and with it more water contamination, air pollution, global warming, and fractured communities.
The natural gas industry, joined in good faith by some environmentalists, touts natural gas as a “bridge fuel,” cleaner burning than coal and less destructive to extract, a way to transition to a renewable energy economy. But communities across America – from the Rocky Mountains to Texas, Pennsylvania, and New York – know this is a false choice. Just like coal, the drilling, processing, and transport of natural gas is dirty and dangerous. And new research calls into question natural gas’s advantage over coal in terms of global warming pollution when the full life cycle (from extraction to transport to use) is considered.…more…
What do you think? Is natural gas a bridge to the future or a dead end?
