All of Minnesota’s Electricity Generation Needs Can Be Met by Wind and Solar

Renewable Project

From 2012 – All of Minnesota’s electricity generation needs can be met by wind and solar sources combined with improvements to the state’s electric grid system and energy efficiency policies, according to a report released. “Renewable Minnesota: A technical and economic analysis of a 100% renewable-energy based electricity system for Minnesota” was researched and written by Dr. Arjun Makhijani and Christina Mills of the Institute for Energy and Environmental Research (IEER) in Takoma Park, Maryland and Dr. M.V. Ramana of Princeton University.

Researchers reviewed the energy production demands and compared to production potential from Wind and Solar methods and found that Minnesota can meet 100% of its energy needs from renewables. In a study published March 2012 the Institute for Energy and Environmental Research based it model on Minnesota energy usage from 2007.

Major components of their analysis are the use of renewable energy storage technology and smart grid technology. The storage technology that they assumed is compressed air energy storage (CAES), which has been used commercially for decades with coal-fired power plants in two locations: Germany and Alabama. Compressed natural gas storage in caverns and aquifers is also a standard technology. CAES is only one option for commercial scale storage technology, and because it has a proven track record, they used it as the placeholder technology for the storage capacity needed.

Renewables Feasible to Replace Fossil Fuels

A renewable energy-based electricity sector is technically feasible, using available and proven technologies. If this is supplemented with an intelligent grid with two-way communication and more efficient use and integration of distributed generation and storage resources, this can help reduce the costs of implementing a renewable energy-based electricity sector.

There are ample renewable resources in Minnesota. There is more than enough wind and solar energy potential to meet the entire 2007 demand of Xcel Energy’s customers every hour and to accommodate growth in the foreseeable future. These technologies are already commercially available. While we have not examined the subject in detail here, there is evidence that the requisite amount of utility-scale storage technology can also be installed within the state.

An efficient, renewable electricity system can be achieved at an overall cost comparable to the present total cost. The added costs of renewable energy generation, as compared to the current generation from mature and fully-depreciated fossil fuel and nuclear generation facilities, can be offset by increasing the energy efficiency of household and building appliances. The net costs of electricity services – lighting, cooling, running appliances, etc., would be the same as today, but partitioned between generation, storage, efficiency, transmission and distribution.

Energy efficiency lowers the effective cost of electricity services and electricity bills.

Climate Change in the Great Lakes

Climate Change

It was December 1st, 2012 and I was listening to no less than three lawnmowers running in my neighborhood in the suburbs north of Detroit. I refused to participate. I’ll admit it was tempting to neaten things up a bit but somehow the idea of running a lawnmower in the same month as Christmas at this latitude strikes me as wrong. What is going on? 

Fast forward to December 2019, here we are again. Temps in the upper 50s in late December and I hear leaf blowers in the neighboorhood, not snow blowers. NOAA’s National Centers for Environmental Information (NCEI) reported that November 2019 was the planet’s second warmest November since record-keeping began in 1880. NASA also considered November 2019 as the second hottest November on record, a scant 0.04°C behind the record-setting November 2015.


Climate Change and Great Lakes Water Levels

Channel Buoy Aground at Caseville Harbor 2012

Back in 2012, it was feared that up to 30 small harbors in Michigan would not open the following year due to low water levels on the Great Lakes. The Caseville harbor was about 18 inches away from being worthless. When we were up for Thanksgiving I noticed a large crane at the Huron Yacht Club (HYC) staged for dredging. The water was below the break wall at the HYC and some portions of the wall at Hoys Marina are in danger of being undermined because the water is no longer holding up the wall. I seriously wondered if we could be able to get Trillium (A 27’ Catalina Sailboat with a 4’ keel) out in the spring.


Climate Change Forces Action Many Will Not Like

Caseville Harbor during low water in 2012 

In 2012 the Detroit Army Corps of Engineers released a report that confirmed my worst fears.  Back then, we have matched the low water point in Lakes Huron-Michigan that was the last set in 1964, 48 years ago. What are worse were the projections.  If they held true, we were guaranteed to fall below the low water mark record through April 2013. (We didn’t) However, if there is a period of too little rain and snow then the situation could easily get to the point where no boat drafting more than 3 feet will be able to use a slip in Caseville. I’m sure that the same situation existed in Port Austin and Harbor Beach.

Now seven years later in 2019, we have the effect in reverse. Due to high rainfall over the entire Great Lakes region, we have near-record water levels in all of the lakes.


What is the Definition of Climate Change

Beach Erosion due to High Water Levels in 2019

Simply put it’s a change in global or regional climate patterns. Particularly a change apparent from the mid to late 1900s onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by human use of fossil fuels. Climate change also refers to notable changes in global temperature, rainfall, wind patterns and other measures of climate that occur over several decades.


Climate Change and Relationships

Are Snow Days Gone?

It was the 1st of December 2012 and a balmy 52F. Fast forward to December 26th, 2019 and the high was 58F. When I was 10 years old in 1974 we had almost 2 feet of snowfall in Detroit in December. That was the second-highest snowfall ever recorded. The dads in the neighborhood all piled into a Pontiac Bonneville to make a beer run and the moms made chili and toddy’s and gathered at the house at the end of the street to sled on their huge hilly driveway and otherwise goof off. Nowadays the weather would never deliver such a break and I would still be expected to log in remotely and do a day’s work via the Internet and cell phone. Have we lost some of the civility with climate change and technology?
