Financial Sense and Climate Sensibility: Renewable Energy at Louisianas Universities ALFS Meeting, Alexendria, LA Dec. 14, 2013 Professor Brian A. Salvatore (LSUS, Dept. of Chemistry and Physics)
Energy Consumption on our Campuses Electricity in Louisiana is cheap! (Commercial rates are $0.05-$0.07 per kWh, among the lowest in the nation). Coal, lignite natural gas, and two nuclear-powered generators are all used here. There is relatively little renewable energy in Louisiana. LSU-BR currently uses 225 million kWh of electricity per year. LSUS uses 12 million KWh per year. Our university campuses are very energy inefficient.
Humidity and Temperature Over 3,000 gallons of water per year were removed from the air in just one room. 15 minutes after the air conditioning is turned off, temperature jumps by ca 10 °F on 3 rd floor of LSUS Science Bldg. (Typical daily temperature range in our Science Bldg. is 69°-95°F in the summer). The fume hoods leak water when it rains. Look up into the ceilings of the top floor of any of our campus buildings, and you can see daylight coming in through cracks.
Lack of Climate Control in Our Buildings (Detrimental to Chemicals and Equipment)
Campus Buildings (Temperature Stress and Structural Integrity)
LA Nat. Guard Training Facility (Camp Minden) Silver LEED Certified Building
LEED Certification Program (GBCI) (Leadership in Energy and Environmental Design) Sustainability (site-selection) Energy Efficiency Building Materials (e.g., recycled) Renewable Energy (wind, solar) Indoor Environmental Quality Design Innovations Four levels of Certification: Certified, Silver, Gold, and Platinum GBCI: Green Building Certification Institute

Solar Cell Production Costs (Example from China)
Despite unprecedented cost reductions for solar hardware over recent years, ca. 50% of the total price paid to plug in residential or small commercial photovoltaic (PV) systems is related to non- hardware (i.e., interconnections, permitting, and inspection). Enabling dramatic reductions in non-hardware costsor "soft cost"of solar is now the greatest challenge to achieving cost- competitive solar by 2020. Federal (and most state) solar tax credits for residential and business customers expire at the end of 2016. Achieving Further Cost Reductions
SunShot Prize ($10 million) Sponsored by the U.S. Department of Energy, the SunShot Prize offers a total of $10 million in cash awards to the first three teams that repeatedly demonstrate an average of $1 per watt for the plug-in price. (i.e. for non-hardware related costs, such as permitting, interconnection, and inspection). Cash awards for the winners of SunShot Prize: First place – $7 million Second place – $2 million Third place – $1 million
Highlights of Conversation with ASUs Professor Harvey Bryan Arizona State University has installed 23.5 MW of its planned 25 MW solar energy system. Ameresco and NRG are the chief developers (ASU uses PPA with its electricity vendors). ASU is ready to install a microgrid on its campuses to facilitate expansion of its solar energy systems beyond 25 MW. The Campus Metabolism website shows the status of the ASU green energy system in real time.
Solar Energy on Louisianas College Campuses LSU-BR will soon announce plans to install a 1-MW of PV solar energy system on the Baton Rouge Campus. This will produce about $90,000 of electricity per year. A 3 MW PV system on each campuses (< 8,000 students) would save $270,000 of electricity expenses per year, which could be reinvested back into academic programs. A 10 MW PV system on campuses (> 8,000 students) would save $900,000 of electricity expenses per year which could be reinvested back into academic programs.
What would it Take to go completely Green? LSU-Baton Rouge 180 MW PV system LSU-Shreveport 9 MW PV system Achieving just 1/3 of total campus consumption by 2025 would be superb, and it is a realistic goal! Is this achievable with todays technology and pricing? Yes it is. (e.g., Palo Alto, CA is currently constructing an 85 MW PV system which will produce power for $0.07 per kWh)
Different Mechanisms for Accomplishment Power Purchase Agreements (PPAs)vendors/developers bear all of the upfront material and installation costs, then sell the power back to the universities guaranteed rate over 20 years (after that the universities own the panels and reap the remaining benefits for the life of systems)---PV panel lifetimes currently >35 years. Statewide Renewable Energy/Efficiency Endowment (goal: raise a $1.5 billion endowment by 2025) raise this endowment through new taxes and fees on public utilities, oil and gas refineries, and/or LNG exports. Be ready for the day (likely within a decade) when these large-scale PV solar installations cost < $1 per W.
