As temperatures drop, solar energy heats up
February 25, 2014
From wisconsinrapidstribune.com: “As temperatures drop, solar energy heats up” — GRAND RAPIDS — Reports of recent propane shortages have made front page headlines across North America, especially in the Midwest, central Canada and California.
For much of January and early February, propane suppliers had difficulty finding the product, and residential customers were paying significantly higher prices. Propane rates are beginning to fall in some places, but this winter’s shortage has been an eye opener for many who depend on propane.
Propane, a byproduct of natural gas processing and petroleum refining, is commonly used for residential heating. Pipeline outages, depleted inventories and a winter with below-average temperatures have increased demand for the fossil fuel. This three-legged onslaught on the supply of propane became a recipe for skyrocketing energy bills; prices doubled or even tripled in many areas.
This sharp increase in utility bills has forced some to pursue other energy options. Mid-State Technical College instructor Ben Nusz points to renewable energy options as a reasonable solution.
“Solar heating is one effective alternative to propane and natural gas,” Nusz said. “A one-time investment in solar brings a lifetime of free energy.”
Nusz teaches for the Renewable Thermal Energy Technician program at MSTC, where he has had the opportunity to use cutting edge energy technology and teach its features and benefits to his students. Equipment in the industry is becoming smaller, more efficient, and, best of all, increasingly affordable by small businesses and homeowners.
Students in these MSTC career programs acquire the knowledge and skills they need to be successful in a burgeoning industry from faculty who have real-world experience. Through this hands-on education, students often have opportunities to leave campus to work with local companies and organizations on real, renewable energy projects. In fact, MSTC even has offered some of its own facilities as hands-on laboratories. Nusz says that arrangement has been a win for all involved.
“MSTC renewable energy program students are receiving a comprehensive education without having to travel far from the classroom,” Nusz said.
Nusz spoke of several student projects that are already up and running. For example, a solar water heating system was installed by students in the Center for Sustainable Energy Technology, a state-of-the-art facility where many MSTC renewable energy classes and labs are held.
Students also have installed a solar air heating system in the Automotive Technician program lab to counteract the high costs of heating a space with numerous doors and bays. This spring students will install a solar heating system that will help heat the greenhouse used in the Urban Forestry Technician program, and plans already are in place for a solar water heating system to heat the cosmetology program’s salon and to provide space heating on the newly remodeled Stevens Point Campus.
“Each of these projects is the result of what the students learned in the classroom and labs,” Nusz said. “Future students will benefit from the effort these students are putting in today.”
While students do not currently log data for the new systems, it is safe to say that these student projects are also saving the college money.
“The icing on the cake is that MSTC facilities are receiving important long-term money-saving and eco-friendly upgrades at a fraction of the normal installation cost,” Nusz said.
Nusz also has good news for people looking to get into an exciting, up-and-coming field. A trend toward increased adoption of renewable energy technology raises the need for skilled people to install and service that equipment.
“There are not enough skilled workers in renewable energy to handle the anticipated growth of the field in coming years,” Nusz said.
MSTC offers four career programs in the field of renewable energy, none of which are available anywhere else in the 16-college Wisconsin Technical College System: Process & Biorefinery Technology, Renewable Energy Specialist, Renewable Electricity Technician, and Renewable Thermal Energy Technician. The latter two programs are undergoing some changes to accommodate local workforce needs and will have new names later this year. All four programs are available at MSTC’s Wisconsin Rapids Campus in Grand Rapids.
