Sustainable Geothermal Energy in Evanston

Introduction

This report highlights the use of geothermal heating and cooling systems in Evanston, Illinois, as a sustainable solution to reduce carbon footprints. It explores the installation process, benefits, challenges, and success stories of geothermal energy in the city.

The Sustainable Development Goals (SDGs)

Geothermal energy aligns with several SDGs:

  1. SDG 7: Affordable and Clean Energy
  2. SDG 11: Sustainable Cities and Communities
  3. SDG 13: Climate Action

Underground Heat Source

Geothermal energy in Evanston primarily utilizes ground source heat pumps (GSHPs) due to the absence of high-temperature reservoirs. GSHPs involve drilling holes and installing vertical loops connected to electric heat pumps in buildings.

Installation Process

  • Holes are drilled approximately 20 feet apart and 100 to 400 feet deep.
  • Two pipes, connected with a U-bend, form a loop inserted into each hole.
  • Vertical loops are connected with horizontal pipes placed in trenches.
  • The loops are connected to the electric heat pump in the building.

Geothermal System Installation

Functioning of GSHPs

In winter, the antifreeze fluid in the underground pipes transfers heat to the heat exchanger, warming the building. In summer, the heat pump removes heat from the building air and transfers it underground, cooling the building.

Global Adoption of GSHPs

The International Energy Agency reports an 11% growth in global sales of heat pumps in 2022. Approximately 50,000 geothermal heat pumps are installed in the US each year.

Success Stories in Evanston

House of Sustainability

The Revelles’ lakeside home showcases sustainable features such as solar panels and geothermal heating. The photovoltaic roof shingles produce 85% of the electricity used in the house, supporting the new GSHP.

Garrett-Evangelical Theological Seminary

The seminary installed GSHPs in two buildings but faced challenges due to deficient technology and insufficient geothermal wells. The system did not provide adequate cooling and relied on campus steam for heating.

Evanston History Center

The historic Dawes House successfully implemented geothermal heating in 2013. The seven GSHPs, supplemented by electric heat, have provided efficient heating for nearly a decade.

Conclusion

Geothermal energy in Evanston offers a sustainable solution to reduce carbon footprints. While challenges exist, successful installations demonstrate the potential of geothermal heating and cooling systems in creating a greener future.
