Bitter Cold Shows Reliable Energy Sources Are Critical

The Star Tribune has published an opinion piece I wrote on how Minnesota's bitter cold should be a wake-up call for energy policy in our state. Instead of mandating the use of wind and solar, which generated just 24 percent of its installed capacity, and provided just four percent of MISO's electricity, we must maintain and keep reliable electricity sources like coal, nuclear, and natural gas plants running. You can read the article by clicking here....

Wind Power Engineering and Development: Why Wind-Turbine Gearboxes Fail to Hit the 20-year Mark

The short, 20-year lifespan of wind turbines is one of the most important, but least talked about facets, aspects of energy policy. American Experiment has written about this topic several times, but as I was researching further I found this interesting article from Wind Power Engineering and Development which states wind turbine gearboxes fail to reach even this milestone. As utility-scale wind turbines have developed from the kilowatt-class to the multi-megawatt machines installed today, the components inside a nacelle have also evolved to keep up with new power demands. Drivetrains, in particular, have had to change significantly to meet stronger, more variable wind loads...

It’s Negative 24 Degrees and the Wind Isn’t Blowing. This is Why We Need Fossil Fuels and Nuclear Power, Not Renewables

Good morning, everyone! I hope you're staying warm. If you are, it's because of natural gas, oil, coal, nuclear power, or even wood, because the wind isn't blowing right now. The screenshot below is from Electricity Map. It's a fun app that tells you how your electricity is being generated at any given moment in time.  Turns out wind is  producing only four percent of electricity in the MISO region, of which Minnesota is a part. While that's not good, what's worse is wind is only utilizing 24 percent of it's installed capacity, and who knows how this will fluctuate throughout the course of the...

EIA Data: Wind Replaced Natural Gas, Not Coal in 2017

The U.S. Energy Information Administration recently released its electricity data for Minnesota in 2017, and boy, were there some interesting findings. One of those interesting findings is that contrary to the popular narrative that by building wind turbines, we will make Minnesota less dependent upon coal-burning power plants. The graph below shows the annualized capacity factor for each generation source in 2017. I've used this graph in recent blog posts but this merits its own 15 minutes of fame in this post. The capacity factor for coal was 61 percent, much larger than the capacity factor for wind at 35.9 percent,...

Minnesota Utilities Spur Wind Turbine Building Boom…In North and South Dakota

Renewable energy advocates in Minnesota claimed that mandating the use of wind for electricity generation would produce a boom in jobs and generate local tax revenue for rural Minnesota, but many of the large industrial wind facilities planned by the state's major utility companies are in North and South Dakota, sending these jobs and revenues out of state....

Peter Foster: Another Report Reluctantly Admits that ‘Green’ Energy is a Disastrous Flop

Despite being the beneficiaries of billions of dollars in subsidies, wind and solar compose just a tiny fraction of overall energy use in the United States. The pie chart below is from the U.S. Energy Information Administration, and it shows that oil, natural gas, coal, and nuclear power provide far more of our energy than wind and solar, which together account for about 3 percent of our total energy consumption....

Want “Carbon Free” Electricity? Promote Hydroelectric Power

Did you know that the Next Generation Energy Act (NGEA), Minnesota's law that requires the state to obtain 25 percent of its electricity from renewable energy sources by 2030, explicitly prohibits counting electricity generated from large hydroelectric sources to measure compliance with the law? However, hydroelectric power is more desirable than wind and solar because it is more affordable, more reliable and more permanent....

Xcel Energy Property Taxes Soar 131.6 Percent Since Minnesota Began Mandating Renewable Energy – Ratepayers are Stuck with the Bill

We at American Experiment often write about how wind and solar energy cause nearly every aspect of the energy grid to be more expensive, but one aspect of this story we have not yet covered is the role wind and solar play on increasing property taxes. Property taxes constitute approximately 6 percent of your electric bill, as utility companies are allowed to pass these expenses directly on to their consumers. As property taxes rise, so does the amount you pay for electricity each month. As renewable energy sources increase on the grid, so do the property tax expenses that ratepayers are stuck...
