Too Much Wind a Bad Thing?

Trying to find a compromise when it comes to wind power has proven difficult. Few can argue with the fact that wind turbines and the power they generate are a good thing, diversifying our energy mix. The point of contention has been between those who believe wind and other renewable can replace coal (and other traditional sources) and those who are not "blown away" by the wind or "overheated" by solar’s potential.

Now there is a new argument, courtesy of a recent study, that the unpredictable nature of wind is causing an actual increase in carbon dioxide emissions. I’ll let the expert, James Taylor of the Heartland Institute, explain. The bottom line, as Taylor points out, is that Washington just might need to slow down on the emission regulations and the renewable mandates.

Government policies designed to fight global warming by encouraging, subsidizing, or mandating renewable power may be making global warming worse.

In a published paper, electrical engineer Kent Hawkins shows when wind power surpasses 5 percent of power generated, the frequent ramping up and ramping down of other power sources to compensate for wind’s unpredictable variability causes such inefficiency in power generation that overall carbon dioxide emissions rise.

For a good analogy, consider this: A driver who keeps his or her speed at a consistent 60 miles per hour will get better gas mileage than one who frequently accelerates and decelerates between 45 and 75 miles per hour. The inefficiency of frequently ramping up and ramping down vehicle speed is substantial enough that the vehicle driving at variable speeds will burn up more gasoline than many vehicles with a lower fuel economy rating.

The same appears to hold true for power generation. Power plants in the Netherlands, Colorado, and Texas switched some of their generation from coal and natural gas to wind power. Because wind speeds are variable and unpredictable, plant operators were forced frequently to vary the ordinarily steady, constant generation of baseload power to back up variable wind power. Whereas a small amount of wind power generation helped reduce carbon dioxide emissions, those emissions began surpassing prior levels once wind power exceeded 3 percent of the power mix.

If the proponents of federal legislation to force reduction of carbon dioxide emissions are sincerely concerned more about alleged global warming than the accumulation of government power to hand out money and favors to preferred industries and contractors, these real-world carbon dioxide facts should put an immediate freeze on renewable power subsidies, renewable power mandates, and cap-and-tax global warming plans. How Congress responds to these new findings will tell us much about the true motivation behind proposed global warming legislation.

In the lawmaking process, as in life itself, rushing to enact "solutions" to speculative problems before the facts are known usually produces more harm than good. Keeping this axiom in mind, Congress need not rush to enact carbon dioxide restrictions on the American economy. After all, total U.S. carbon dioxide emissions are falling, not rising, and they have been declining for the past decade. To the extent global emissions are rising, the fault does not lie with the United States. 

Kharbanda: Manufacturing Opportunities Lie at Intersection of Economy and Environment

Jesse Kharbanda is the Executive Director of the Hoosier Environmental Council, Indiana’s leading environmental educator and advocate.

In this world of intense global competition, where does Indiana’s industrial future lie? Logistics, biosciences, and clean car technologies have been some of the areas that we’ve seen Indiana industry focus on. Indiana, in our view, has yet to tap into another sector – clean electricity component manufacturing, which produces the goods that make wind turbines briskly spin, solar panels soak in the sun, and air conditioning systems be energy hogs no longer. Indiana is surprisingly well positioned to lead in this sector: According to the Renewable Energy Policy Project, a DC-based think tank, Indiana has the second highest potential in the country to produce such goods.There’s no doubt some such companies, like Brevini Wind near Muncie, are locating to Indiana due to our business-friendly environment as it is.

But how might Indiana fully realize this potential, and actually become the second highest job generator of clean electricity jobs? Ask venture capitalists and commercial clean electricity developers, and they’ll tell you pointedly that Indiana needs a dedicated renewable energy policy: a Renewable Electricity Standard (RES), and a robust net metering program. Unfortunately, we’re the only state in the Midwest without the former, and we have the weakest net metering policy in our region. Policies like an RES and strong net metering have a triple dividend: they make Indiana a more hospitable climate for clean electricity manufacturing jobs, they move our electricity sector towards energy sources that are better for our health and environment, and they hedge against regulatory or economic-induced fossil fuel price shocks.

An organization like HEC and a trade group like the Indiana Chamber may not be in complete alignment on the right policy solution, but for the sake of jobs and improved environmental quality, let’s a find a way to work together to make sure that Indiana is a leader in this sector, a sector that will mushroom in the decades to come. HEC’s hand is extended.
