Natural gas versus coal

You and I use a lot of energy. Every second of each day and night we devour 100 times more energy than we need to live.  If I were to eat that much energy as food, I would be a 50-foot long bull sperm whale, weighing 40 tons.  There are 300,000 sperm whales worldwide, half of them bulls (females are much smaller), and 300,000,000 Americans (females are about the same in size).  Our Earth cannot feed and protect 300,000,000 male sperm whales.  She is simply too small. Our voracious appetite for energy must be either extinguished or quenched with local sources of energy (and, no, wind turbines and PV cells are too small to provide even single ample energy meal per day). So here are some of the choices we have:  We can drill and hydrofracture deep gas wells, and produce natural gas closer to where we live, or we can go after coal leftovers. We can also opt not to use fossil fuels and live differently, more Amish-like. For example, we can opt to live in the well-i...

Radioactivity in water and natural gas fracing

In this post I attempt to provide a context for an article in NYT, Drilling Down: Regulation Lax as Gas Wells’ Tainted Water Hits Rivers by IAN URBINA, published on February 26, 2011.  The article seems to imply that much of the potentially deadly radioactive contamination of drinking water supply in Pennsylvania comes from "frac water" produced after hydrofracturing the deep natural gas wells there.  Such an assertion is not supported by facts, and here is why. The raw data from the NYT spreadsheet, emailed to me by Mr. Urbina, are plotted here .  In the spreadsheet, there are up to five different measurements of radioactivity in the water produced from each of 212 natural gas wells in Pennsylvania.  Total alpha radiation refers to all alpha-particle-emitting radioisotopes present in the produced water.  In some wells there were additional measurements of alpha-radioactivity from two isotopes of radium and two isotopes of uranium.  By subtraction, the d...
