There are no easy answers to heating with gas.
The Sparrows Point large-scale liquefied natural gas marine import terminal all by itself could be a disaster. The liquefied natural gas tankers have been called “floating bombs” with the explosive potential of a Hiroshima sized atomic bomb sans-radiation. A large scale leak could also “fast freeze” a large area at −260 °F.
Drilling in Pennsylvania’s forests for natural gas is both an environmental problem and could endanger water supplies.
Gas pipelines themselves have exploded with deadly results.
If we are going to use natural gas there are no easy answers.
In order to minimize the risk, very strict regulations with strong teeth are a must. But right now we have soft regulations and an extremely sparse regulatory staff.
