As each University of California campus prepares to publish its long-term plan for eliminating carbon emissions and transitioning to renewable energy, a new shares how sustainability experts on three campuses 鈥 Davis, Berkeley and Santa Cruz 鈥攁re phasing out fossil fuels ahead of schedule.
Each of these campuses has different challenges and considerations as they transition to renewable energy, but they have a few important things in common: committed leaders building teams who embrace the challenge, staff and faculty with deep expertise in engineering, climate science, sustainability and social transformation, and an energized community of activists pushing for urgent change.
新澳门六合彩内幕信息 Davis makes a Big Shift
At 新澳门六合彩内幕信息 Davis, the transition to green energy is already well underway. A year ago, crews finished the first phase of what鈥檚 known around Davis as the , replacing the campus鈥檚 natural gas-fired steam apparatus with a system that can use electricity to generate hot water instead. During two years of construction, crews dug great big trenches through the heart of campus, laying four miles of new pipe and swapping out steam heating systems with those that run on hot water in 31 buildings.
For the time being, Davis is burning fossil fuels to heat the water that鈥檚 running through the new pipes. But once all the buildings that are connected to this centralized heating and cooling system have been retrofitted, they鈥檒l be able to shut down the natural gas-powered boilers and run the whole system on electric heat pumps. Altogether, the project will shrink Davis鈥 carbon footprint by 80 percent.
Altogether, the project will shrink Davis鈥 carbon footprint by 80 percent.
Davis leads 新澳门六合彩内幕信息 campuses in decarbonization today in part because this transition has been in the works for 15 years, said Joshua Morejohn, Davis鈥檚 executive director of utilities and engineering.
Back in the aughts, 鈥渙ur steam system was 50 years old and going to need to be renewed,鈥 Morejohn explained. In studying alternatives, they found that sticking with steam, which is volatile, expensive and inefficient, was actually going to cost the campus way more money in the long run.
鈥淲e cobbled together all the near-term steam projects in the budget, which got us about $50 million. So we said, 鈥楲et's spend that $50 million on the first phase of a hot-water system that could eventually run on zero-carbon energy,鈥欌 Morejohn said.
Decarbonizing 新澳门六合彩内幕信息 鈥 not to mention the rest of our economy 鈥 in time to avoid complete climate catastrophe is going to take a lot of these kind of 鈥渂ig cultural shifts,鈥 says Ellen Vaughan, assistant director of sustainability for operational and strategic initiatives at 新澳门六合彩内幕信息 Santa Cruz.
鈥淵ou might be able to find 90 percent of the cost of an electrification project in the budget that鈥檚 already been allocated for fossil fuel infrastructure replacement. You just need to realize and be excited about the fact there is an opportunity to electrify, and that you don鈥檛 have to replace a natural gas boiler with another natural gas boiler.鈥
How decarbonization supports teaching, research and public service
The three 新澳门六合彩内幕信息 campuses leading the green transition have drawn on the collective brainpower of thousands of students and faculty to generate the most efficient, effective and equitable solutions for each campus. Along the way, they鈥檝e generated valuable new scientific insights while providing hands-on educational opportunities for the next generation of climate leaders.
鈥淐limate change is totally an interdisciplinary problem, so it makes sense that we鈥檇 go after it with multidisciplinary groups,鈥 said Kurt Kornbluth, assistant professor of biological and agricultural engineering at 新澳门六合彩内幕信息 Davis.
For the past dozen years, he and Morejohn have co-taught a project-based class called . Students with backgrounds in everything from engineering to classics have worked together to audit campus building energy use, generate new algorithms for managing water use on campus and even develop the business case that Davis is using to fund the transition from steam to hot water and climate-warming fossil fuels to renewably generated electricity.
Kornbluth and Morejohn also co-lead a campus-backed initiative called Sustainable Campus Sustainable Cities, which casts 新澳门六合彩内幕信息 Davis as a living lab for research and education focused on eliminating 新澳门六合彩内幕信息 Davis鈥檚 carbon emissions. Each year, the initiative hosts a workshop connecting sustainability leaders at colleges and universities around the world.
鈥淥n a lot of these issues, our students are the ones doing the consulting for the campus, instead of us having to hire someone from outside. I can use these projects as a springboard for my own research as a professor. And students are getting amazing experience, and they all get great jobs after graduation,鈥 Kornbluth said. 鈥淭he faculty benefits, the students benefit, and the campus benefits.鈥
