It has been interesting to read recent opinion pieces regarding our electric grid and the role of solar and wind power. I doubt that many of the writers truly understand the benefits of solar and the downside.
I have a second home at the end of the Arrowhead Trail in northern Minnesota. The closest electric pole is 16 miles away, forcing each home to either run a generator or use solar, wind or both to get electricity. I started my solar journey 16 years ago. The initial investment was substantial ($21,000), as you literally become your own utility company. I'm on my third generation of batteries for storage of energy, upgrading to three 48-volt lithium batteries at a cost of $5,000 each and increasing the number of solar panels from eight to 16. Why? Around half of Minnesota days are cloudy. With all this solar power, I still need my generator for backup if the cloudy days exceed two in a row.
This solar journey has made me aware of how we use electricity, which appliances are energy pigs (hair dryer, toaster, coffeemaker) and taught me to wait for sunny days to do laundry. My point: Solar has made great strides, but has a long way to go.
Our future electric sources should be diverse, and our appliances and buildings more efficient.

POLLUTION
As air quality declines, need for clean cars increases
The Minnesota Pollution Control Agency (MPCA) issued an air quality alert last month that air pollution from fine particles would be at dangerous levels for a few days. These are the particles that easily lodge in the lungs, leading to health concerns for children, the elderly and people with pre-existing asthma, emphysema and heart disease.
The air quality alert tells us that everyone should take precautions by limiting physical activity, staying away from local sources of air pollution such as busy roadways and making sure you carry an inhaler if you have breathing conditions. Fine-particle pollution comes from any activity that uses fuel.
Minnesota is having many more of these air-quality-alert days. The alarms are going off for Minnesotans to support the Clean Cars Minnesota rule. The state is behind on its goals for greenhouse gas emissions set in a bipartisan legislature in 2007. Additional emission reductions are needed to achieve these goals. Transportation is now the largest emitter of greenhouse gases in Minnesota.
With fewer gas-powered cars on the road, the air could get a lot cleaner. During the pandemic shutdown last spring, we all got to observe that there was very little traffic, resulting in blue skies and clean air. The Clean Cars Minnesota rule will improve our air quality with stricter fuel efficiency standards. Minnesotans will have access to more choices in hybrid and electric vehicles. Cleaner cars will help us meet the urgent goal of 55% clean energy by 2035.
