So we come to the question of how the West can eliminate its reliance on Russian oil and gas in the quickest and most advantageous manner. And in this regard, my mind was provoked recently by hearing of a few design and construction projects in the northern U.S. which are replacing natural gas-fired space conditioning equipment with all-electric, variable refrigerant flow heat pump HVAC systems at a number of government facilities. Many of the facilities in question already have existing rooftop solar photovoltaic (PV) systems, which can be used to offset the energy cost of the new HVAC systems.
These projects are an example of a larger trend in the architecture/construction industry and among facility managers to shift from buildings which use fossil fuels for space conditioning to buildings which use electricity only. There are encouraging reports and studies which indicate that, given the current trends in the development of renewable energy sources and advances in HVAC systems, a shift to all-electric buildings can be significantly cheaper in the long run than maintaining buildings that continue to use fossil fuels. I don't have time today for a detailed analysis of the literature on this subject, but I do intend to write a few posts that go into this subject in more detail as soon as I have time for more intense research. However, for those who want to beat me to the punch (please do!), the following sources are a good place to start:
- A Case for Electrifying Heat In End-Use Residential Sector Towards Carbon-Free Buildings, Tolu O. Sodeinde, Massachusetts Institute of Technology, 2019
- "Efficient Electrification Newsletter," Electric Power Research Institute, January/February 2020
- "Edison International Sustainability Report 2019", Edison International
- "NBI BETR Webinar, 2-22-2021", New Buildings Institute
- And, for something slightly more cautionary, "Increased Electrification of Heating and Weather Risk In the Nordic Power System," Trotter, et al, Norwegian University of Life Sciences, December 2021.
Of course, any large-scale transition to an all-electric society must rest on a foundation of cheap, widely available electricity from renewable resources. Here we have research that shows a very optimistic picture, as stated in an April 2019 report from the German Energy Watch Group in partnership with the Lappeenranta-Lahti University of Technology (aka LUT University) in Finland. The title of the report is Global Energy System Based on 100% Renewable Energy: Power, Heat, Transport and Desalination Sectors. A key paragraph from that study is the following:
"A transition to a global 100% renewable energy system is no longer a matter of technical feasibility or economic viability, but one of political will. Not only do we need ambitioustargets, but also stable, long-term, and reliable policy frameworks, adapted to regional conditions and environments. We call on the global community to urgently pursue a forward-looking pathway towards net zero GHG emissions by launching a rapid change of the way we use natural resources and provide electricity, heat and transport." - Hans-Josef Fell.
One of the findings of the study is that regional energy independence can be achieved by the development of regional renewable energy resources, as described in the paragraph titled, "Electrification and Decentralisation Lead To More Efficiency." This would eliminate or at least drastically reduce the need for import of energy by one region from other regions.
Clearly these topics deserve deep and urgent consideration!
