Expensive Energy

Do “green” energy subsidies work?  Pretty much by definition, they do not.  Without the subsidies, “green” energy is unsustainably expensive.  Even—especially—when the subsidy is a government mandate to use/buy the “green” energy, the only thing green about it is the money necessary to buy it.  The cost of the ethanol subsidy/mandate in our gasoline has been well documented as appearing not only in the cost of our gasoline, but in the cost our food, as well.

Wind energy provides another example of an expensive, and failed, “green” energy subsidy.  The Wall Street Journal writes

Twenty-nine states have these rules requiring local utilities to purchase between 20% and 33% of their electric power from renewable sources.

Minnesota, in particular, the WSJ reports, required as recently as 2007 that utilities in the state push their use of renewable energy  to 25% by 2025, to 12% by this year.  That means wind energy because in that Midwestern and northern state, the sun doesn’t shine as much as it does in New Mexico or Arizona.

The Minnesota Rural Electric Association says its members lost $70 million last year because these utilities are forced to buy wind power they “can’t use and can’t sell.”  Even so, residential utility bills for MREA’s customers run $50 to $100 per year higher than they would absent the mandate.  That’s not chump change for Mr Everyman.

What are Minnesotans getting for their extra $100 of energy expenditures?  Nada.  Not more energy.  The wind does not blow all the time, so the wind mills stand idle while still costing money.  When the wind blows too hard, the wind mills must be shut down, so they stand idle while still costing money.

Not more jobs.  Minnesota’s wind-generated electricity doesn’t come from wind mills built in Minnesota.  They import it from North Dakota.  When the wind is blowing just right.

The WSJ also described a study published this year by the Manhattan Institute, a New York City-based market-oriented think tank, that compared states with renewable energy mandates with those that allow utilities to purchase the cheapest electricity available.

The states with mandates paid 31.9% more for electricity than states without them.  Residents of North Dakota, a state without a mandate, pay $7.63 per kilowatt hour for electricity.  Neighboring Minnesota pays $10.76.

Hmm….

Thoughts on Defense Spending

Mark Gunzinger and Andre Krepinevich (with the Center for Strategic and Budgetary Assessments, a non-profit defense-oriented think tank), writing in The Wall Street Journal, warn of a reversal of events that contributed to the collapse of the Soviet Union—an arms race that they couldn’t afford and so couldn’t win.  This time, it’s Russia and the People’s Republic of China that are pursuing an arms race, this time of powerful, fast, accurate weapons that will bankrupt us countering, if we don’t change our weapons philosophy.

Russia and the PRC are actively developing high-energy lasers designed to shoot down incoming weapons, while we continue to rely on expensive—$10 million per shot—missiles and fighters—$150+ million—per to do the same mission.

Gunzinger and Krepinevich report on two types of lasers that we could field in six years, were the will extant to make the switch: solid state and chemical lasers.

Experts in the US Navy state that within six years, using technologies already developed and demonstrated in test firings, they could field solid-state lasers on warships with sufficient power to counter anti-ship cruise missiles, unmanned aircraft, and fast-attack “swarm” craft like those of Iran.  These lasers could reduce the need for warships to carry bulky—and expensive—defensive munitions, while freeing space for other weaponry.

On the matter of chemical lasers, they write

…new chemical lasers can generate much greater power outputs than their predecessors, enabling them to engage a wide range of air and missile threats, including long-range ballistic missiles. Also within six years…the Air Force and the Army could field ground-based, megawatt-class chemical lasers to help protect key bases in the Persian Gulf and Western Pacific.

And in the homeland.

But that’s just one set of game changing weapons.  Another weapon is the rail gun on which the Navy also is working.  Rail guns use electromagnetic energy rather than explosives—gun powder—to accelerate a projectile down their barrels.  As a result, such weapons can fire accurately a projectile much farther—out to 100 miles vs a current 13 miles—and the ships carrying them don’t need to commit limited shipboard space to that gunpowder, and so they don’t have to worry about all that explosive going off if the ship is hit in combat.
