Alberta Fracking Regulation

Alberta is looking at updating its regulatory framework for hydraulic fracturing practices. As a farmer and rural land owner, I particularly like the idea of having baseline studies of ground water quality done before development occurs.  This is an essential...

Regulating GMO Seeds

Tom Philpott over at Grist has written a post complaining about the USDA allowing proponents to fund environmental assessment studies required to satisfy Environmental Impact Assessment regulations.

In early April, the USDA made what I’m reading as a second response to Judge White, this one even more craven. To satisfy the legal system’s pesky demand for environmental impact studies of novel GMO crops, the USDA has settled upon a brilliant solution: let the GMO industry conduct its own environmental impact studies, or pay other researchers to.

His complaint makes for a nice sound bite.  However, if he is going to prevent
GMO technology developers from sponsoring environmental impact analysis, is he proposing to prohibit that practice in the pharmaceutical sector?  Should new drugs be held off the market until government researchers get around to conducting their own research on the safety of new medications?

Electricity – Reliability, Availability & Redundancy

Intermittent sources of power production such as wind, solar, and bio-gas are frequently criticized as being too intermittent and unreliable to be of value to the electrical grid.  The argument is often put forward that every megawatt or wind energy capacity has to be backed up with another megawatt of production capacity somewhere else on the grid so power is available 7-24.

On one level, that criticism ignores that the direct variable operating cost of wind and solar energy is nearly zero unlike thermal energy plants like gas, coal or nuclear which must pay for fuel to produce energy.

Thermodynamics Tutorial

Both Grist and Watts up with That have posted the following chart that provide a graphical illustration of energy use in the United States.  The comments after the primary post at the Grist site are worth a read.

While the first impression is that the amount of “rejected energy” suggests there is substantial room for improvements in efficiency, some deeper analysis and commentary is required about the fundamental limits presented by the laws of thermodynamics.  In addition, the assumptions used to produce the charts are quite broad brush and border on being simplistic.
