If local citizens want to assuage their guilt about energy use and carbon footprints they must first prepare themselves for a few simple inconvenient truths. That's because some wind and solar true believers conveniently dispense with rational discussion concerning what's possible to achieve in meeting future electric energy needs along with what it will cost to make significant gains. Were it not for the huge taxpayer subsidies the "green" revolution promised for wind and solar would not be possible. ... Our Department of Energy wants to achieve that 20 percent goal by the year 2030 and some States even want a more ambitious goal. Fortunately there are people who recognize that in order to achieve these goals we will need to build twice as much capacity because it isn't always windy where it needs to be.

These days we read and hear more and more about the exponential increases in renewable energy, particularly large wind farms such as those sprouting up on Colorado's front range and eastern plains. Colorado's Amendment 37 requires the state's largest utility companies to produce 10 percent of their energy from renewable sources by 2015. A subsequent legislative action doubled that to 20 percent by 2020. ...This is all great news, right? Not if you are an independent grid system operator, and not if you're expecting all of this large scale wind power to help reduce global warming carbon emissions. Wind power is by nature a notoriously intermittent source of power. Wind simply doesn't blow steadily all of the time. Therefore, the power output of all large scale wind farms goes up and down dramatically throughout the day, regardless of the demand for power on the grid. ...Without energy diversity, the more renewable power we mandate, the more unreliable the grid will become. The laws of physics simply can't be amended.

Colorado is vulnerable due to its current low prices is in its efforts to implement renewable energy solutions. While other states, including California and Massachusetts, take on large scale efforts for wind, solar and other renewable and clean energy production opportunities, the low cost of energy in Colorado makes these energy investments by utilities, private companies, and Colorado residents, not economically viable when compared to the current low cost of traditional fossil fuel based energy in Colorado. This means that, in spite of our Governor's strong emphasis on making Colorado the renewable energy state, current low prices for traditional energy hinder Coloradans, our venture capital sector, and our companies from jumping on this clean energy bandwagon with significant investment.

Reserve generating capacity, normally 10 percent to 15 percent, could be down to 1 percent or zero percent in some places, and Yale professor Charles Perrow, who follows power-supply shortfalls, says "I'm prepared to see many more blackouts occurring. . . . it's really going to be a freight train running into disaster." This is not an encouraging scenario, to say the least. ...Here is one decisive piece of realism: Coal supplies more than 50 percent of U.S. electricity and more than 80 percent of Colorado's electricity. Due to its abundance and price stability, coal will - and must - continue to be a major source in meeting U.S. and world electricity demand for decades to come. While proponents of alternative energy are often adamant in their rejection of coal as a continued long-term energy resource, reality dictates otherwise. To dismiss this reality is simply dangerous - dangerous to long-term energy supply and price stability.

Wind power has all the ingredients of a good brain-buster. The energy that windmills produce helps to preserve the environment, but the giant wind generators themselves have to be added to the environment. Wind power is making us redefine what we consider pollution. Windmills may not billow black smoke that requires scrubbing or leak hazardous radiation, but they make a lot of noise and can change a scenic horizon or ridgeline into a jumble of tinker-toy technology. Like dams in rivers, they interrupt the free flow of natural settings.

So why is this higher mandate likely to hike your bills? Because when government creates an artificial market by fiat, shortages almost always follow (of turbines for wind power, for example), thus boosting the mandate’s cost. For that matter, if all forms of renewable energy could compete on their own, they wouldn’t need a mandate in the first place.

When the country thinks about its energy problems, it often focuses on our dependence on foreign oil and the recent high prices of gasoline. Petroleum provides 40 percent of our energy and is particularly vulnerable to geopolitical swings in unstable regions of the world. But utility executives worry that Americans are failing to appreciate another aspect of the energy picture, namely that the power plants using coal, natural gas and nuclear power to produce electricity may soon not meet our growing needs. "My biggest fear is that we are running out of generation," said Michael G. Morris, chairman and chief executive of American Electric Power, with 5 million customers in 11 states. "That is an issue that the average person doesn't know a thing about. When we tell corporate America, they say, 'What do you mean you're running out of power?"' The executives' concern is echoed by the North American Electric Reliability Council, which last week said in its annual report that in two to three years, the margin between power supply and demand will drop below levels necessary for reliability in Texas, the Northeast and the Midwest. Other parts of the country could reach that point in the next decade.

For years Vail Resorts has claimed it would actually build wind turbines on its mountains. It appears that was all marketing hyperbole, or as environmentalists like to call it, "greenwash." I can only imagine that the recent wind power purchases of renewable energy certificates by Vail Resorts is their attempt to buy their way out of past environmental marketing claims.

DENVER - The House passed and sent to the Senate a bill that attempts to lure more wind farms to northeastern Colorado. The vote was 54-9 earlier this week.

To be sure, we are at a crossroads in energy and need all kinds of ideas to supply the enormous demand that is now filled by fossil fuels; however, I’m not ready to surrender the last open prairies to this version of energy independence.

Xcel says wind power will mostly supply intermittent and peak power - energy demands that fluctuate day to day or even hour to hour. Unfortunately, that means it still must rely on coal, the most polluting fossil fuel, supplemented by natural gas, the most expensive fossil fuel, for its base load (the kind of electricity that's always on).

Wind energy is environmentally harmful and costly to taxpayers. Furthermore, its expansion could adversely affect the nation's electricity transmission system.
