Paul Cutting, Energy Planner Most of us probably understand the general concept and benefits of home electrification. Electrify all aspects of our daily lives–from space heating, water heating, home cooking, to transportation–while at the same time increasing the share of renewables on the power grid. After all, in 2021 about 57% of Iowa’s power mix came from renewables. Grid power aside, electrification presents many challenges and expenses beyond just the
By Paul Cutting, Energy Planner Ductless heat pumps are exciting for their potential to serve as low-cost, straightforward and simple solutions to home heating electrification. As the name implies, ductless heat pumps use interior units that have incorporated evaporator coils and blowers to deliver heating and cooling to interior spaces. You’ve likely seen interior mini split style wall units that hang close to a ceiling. Along with wall units, there
By Andy Johnson and Warren McKenna Click here to read the pdf version with footnoted sources Here we go again. Grid operators and utilities are issuing dire warnings about looming blackouts this winter, and often linking the threat to the closure of coal plants. The narrative serves utilities like MidAmerican Energy well, whose parent company Berkshire Hathaway Energy is one of the dirtiest utilities in the nation. MidAmerican would love
Andy Johnson, Executive Director We wrote back in June about how the clean grid of the future can indeed be an increasingly reliable and resilient grid. It was an effort to counter the narrative that reliability will only come through continued reliance on aging (and in fact, increasingly unreliable) coal plants. That narrative continues to be promoted by MidAmerican Energy, whose parent company Berkshire Hathaway Energy ranks nationally in the bottom five of the
Andy Johnson, Executive Director It is abundantly clear that we need more large-scale solar (and storage) to complement the high penetration of large-scale wind in Iowa and promote a cleaner and more reliable grid. Yet the siting of utility solar projects has become increasingly difficult, thanks to a vocal minority of anti-renewable advocates that appear to be increasingly politically motivated and often funded by fossil fuel interests. The University of Iowa’s Hubbell Environmental
Andy Johnson, Executive Director The Clean Energy Districts of Iowa was invited to join USDA Rural Development leaders in presenting at the Organization for Economic Cooperation and Development’s Rural Development Conference in Ireland. The theme of the September OECD gathering was “Building Sustainable, Resilient, and Thriving Rural Places”. CEDI Executive Director Andy Johnson discussed the universal-local Energy District model, and the Energy District’s partnership in implementing USDA’s Rural Energy for America Program,
Paul Cutting, Energy Planner Prolonged power outages in the wake of natural disasters show the value of solar with backup battery capabilities. Following Hurricane Ian back in September, many areas were left without power for weeks, and as Decorah residents witnessed last December following a freak early winter storm, the power can go out for extended periods of time. Utilizing a stationary backup battery like the 13kW Tesla Powerwall, while
Air source heat pumps powered by electricity (from here on out referred to as heat pumps) and used in conjunction with propane furnaces or as standalone units have significant operational and carbon savings benefits compared to only using propane. Compared to electric resistance heating, air source heat pumps are significantly cheaper to run. And compared to natural gas, heat pumps have comparable operating costs but significant carbon savings benefits.
by Paul Cutting, Energy Planner High energy bills are expected this year. (Read this article for an analysis of why.) What can you do to get ready? First of all, go after all the low hanging fruit like air sealing and making sure your furnace is in good working order. Generally speaking, the biggest sources of air intrusion/extrusion through a house are the basement and attic. In the basement, make
