Is There Still Time to Avoid ‘Dangerous Anthropogenic Interference’ with Global Climate? Dr. James E. Hansen Director, NASA Goddard Institute for Space Studies December 6, 2005

Dr. James E. Hansen, continued: 

Dr. James E. Hansen, continued “Warming of more than 10C above today’s level will make the Earth warmer than it has been in a million years”. “Business-as-usual, with fossil fuel CO2 emissions continuing to increase will mean an additional warming of 20C to 30C this century and will make the Earth a different planet.” “At 20C to 30C the new equilibrium sea level is approximately 25 meters (80 feet) higher than today. Real world data suggest sea level changes in centuries rather than millennia.” “Action must be prompt, otherwise CO2- producing infrastructure will be built within a decade that will make it impractical to keep further warming under 10C”. “I refer especially to the large number of coal-fired power plants that China, the U.S. and India are planning to build…”

Adopt these Targets: 

Adopt these Targets All new buildings, developments and major renovations meet a fossil fuel energy-consumption performance standard of 50% of the regional (or country) average for that building type. That at a minimum an equal amount of existing building area be renovated annually to use 50% of the fossil fuel energy they currently consume. Increase Fossil Fuel Reduction Standard to: 2010 – 60% 2015 – 70% 2020 – 80% 2025 – 90% Goal is to be Carbon Neutral by 2030 No Fossil Fuel to Operate our Buildings

California’s Energy Efficiency Programs’ Resource Value Compared to a Potential Water Use Efficiency (WUE) Program : 

California’s Energy Efficiency Programs’ Resource Value Compared to a Potential Water Use Efficiency (WUE) Program How do your energy efficiency programs compare to the potential energy savings due to water use efficiency?

Water-Energy Relationship:Synergies : 

Water-Energy Relationship: Synergies End-User Water and Energy Conservation Saving water can save energy Saving energy can save water Improve Price Signals Time of use water rates and meters Time of use electric rates and meters Water and Wastewater Utility Operational Efficiency Increasing water and wastewater system efficiency reduces energy in the water use cycle Water Storage Increased water storage and more flexible water storage shifts peak energy requirements Pumped storage increases peak electric generation and improves electric system efficiency Renewable Generation by Water and Wastewater Utilities Increase generation from in-conduit hydro and biogas. Add generation from solar and wind. Assist in meeting California’s renewable generation goals If we did all this, what would be the combined impact on GHG emissions?
