  1. Energy Use, Renewable Energy and SUNY ESF Climate Action Plan March 30, 2010 Michael Kelleher SUNY College of Environmental Science and Forestry

  2. World Energy Use Exajoules

  3. Global Energy UseEnergy Consumption and Affluence are Linked (J.R. Fisher, 2005)

  4. Population of Industrialized Countries Global Energy Situation 12 1400 1200 10 1000 World Population 8 800 Population (Billions) Energy Consumption (Qbtu / yr) 6 World Energy Consumption 600 4 400 2 200 0 0 1900 1950 2000 2050 2100 Year Energy Projections: “Global Energy Perspectives” ITASA / WEC Population Projections: United Nations “Long-Range World Population Projections: Based on the 1998 Revision” (J.R. Fisher, 2005)

  5. For every 100 BTUs of energy supplied, 44 BTUs are consumed, and 56 BTUs are “lost” due to inefficiencies (primarily combustion)

  6. Renewable Energy Plays a Role in the Nation’s Energy Supply (2007) About Half of States Have Renewable Portfolio Standards (RPS) and Renewables Mandates, 2007

  7. Cost Comparison Lazard: Levelized Cost Of Energy Analysis Version 2.0 June 2008

  8. Sensitivity to Fuel Price Variations (+/- 25%)

  9. Importance of Tax Incentives

  10. Willow Biomass Production Cycle Site Preparation Planting Harvesting Coppice First year growth Early spring after coppicing Three-year old after coppice One-year old after coppice

  11. Willow Biomass Crop Carbon Cycles CO2 Recycled 100 % Carbon Closure (Assumes 0.25 t/ha-yr increase in soil carbon) 1 J 11-16 J 55 J Feedstock Production (62%) Net CO2 Emissions: 0% Transportation (12%) Power Plant Construction (26%) (Mann and Spath 1997, Heller et al. 2003)

  12. ESF Energy Inputs* - 2007 184,395 MMBtu * reflects energy use factors

  13. Five-Fold Path Energy & Emissions Reduction Total: 40 Initiatives • Energy Conservation Measures - energy saving renovations, technologies, & facilities upgrades. • Alternative Energy Projects -onsite clean & renewable energy projects to power existing structures. • Green-Building Energy Systems - design of new construction with integrated renewable energy systems. Ultra efficient building envelopes allow surplus energy to flow to other buildings. • Campus Action Campaigns - efforts by ESF community for increased awareness, voluntary behavioral adjustments, policy changes, reduced waste, etc. • Forest Carbon Sequestration - designation & management of select ESF forest properties for carbon sequestration & storage purposes.

  14. Sustainability Starts with Conservation ESF High Efficiency Chiller Replacement and Energy Audits, and modified behaviors. • $1.2M chiller replacement saves ESF $170,000/yr and reduce annual oil consumption by 2,500 barrels/yr • Thermostat settings, reduced in winter & increased in summer. (very cold over winter break) • Turn off the lights and computers! • NYPA financed energy audits and efficiency improvements. Conservation = efficiency /

  15. ~80% Conversion efficiency 17% of campus electrical requirements Funded by Grants: NYSERDA US DOE EPRI ~$1.5M Fuel Cell, Efficient Power and Heat Generation

  16. Photovoltaics • 40 KW of installed ($400,000) • $200,000 funded by NYSERDA

  17. Gateway building – LEED Platinum New “zero net energy” showcase building for campus. Design includes biomass combined heat and power, PV, green roof, passive solar and rain gardens.

  18. Gateway Building Energy Efficiency

  19. Gateway Energy System • 8,000 MBtu CHP Wood Pellet Steam Boiler • 8,000 MBtu CHP Natural Gas Boiler • 200 kW Back-pressure steam turbine • 30 kW CHP Biodiesel Micro-turbine • Dual 65 kW CHP Natural Gas Micro-turbines • 150-200 kW Solar PV array

  20. Combined Heat and Power System • CHP System is a 25% improvement to overall energy efficiency • Provides 75% of campus thermal needs and 20% of campus electrical needs. • Offset 54,000 MMBTU Fossil Fuels Annually • 18,000 MMBTU from efficiency improvements • 36,000 MMBTU from fuel switching improvement • System is projected to save ESF $450,000 annually, and provides a $1.5 million NPV over 15 years
