  • Annual world-wide investment of $170 billion in energy efficiency through 2020 could: cut global growth in energy demand by ½! save $900 billion a year in avoided energy costs dramatically reduce greenhouse gas emissions Source: The McKinsey Global Institute “ Energy efficiency is the nation’s greatest energy resource—we saved 50 quads in 2007 due to energy efficiency and conservation efforts taken since 1973. This is more energy than we get from any single energy source, including oil.”   “ If we tried to run today’s economy without the energy-efficiency improvements that have taken place since 1973, we would need nearly 50% more energy than we use now. This is more than what we get from any single energy source, including oil, natural gas, coal, and nuclear power.”
  • Global – IEA says 300 EJ potential EE in 2050 - -25 GT Co2 Measures below line are measures that would pay for themselves, even without a carbon price – CCE less than cost of buying energy. Will talk more later about why those negative cost opportunities are there (or might not be there). (Larry may have something to say about this later) But forgetting whether costs are “negative,” the point remains that EE is often less costly than the other abatement options. EE about 1Gt = about one sixth of current emissions CO2 price will likely be higher. Once you move into higher carbon price ranges, it is hard to know what technologies come out of the hole. 2030 EE potential reductions CO2e ( 1208 ) Buildings                                               743 Mt Residential ( 362 )                                                           Commercial ( 381 ) Industrial                                               278 Mt Transportation (cars only)          186 Mt Non-EE potential                             1,792 Mt
  • That “negative cost” measures are not already implemented suggests some non-price barriers exist. But some of these non-price barriers COULD be affected by higher energy prices – underestimated costs, information barrier, lock-in, even split incentives. Requires hundreds of billions of “cost-effective” investment Constrained budgets (time & money) Uncertainty (project performance and energy costs) Flowing information
  • Some info. : A report from 2007 says: Turkey is a net energy importer and of its total primary energy consumption; the largest fuel type is oil.   The industrial sector in Turkey accounted for 40% of total final energy consumption and for 54% of electricity consumption in 2000, and industry has been targeted as a priority area for energy conservation programs owing to the projected rapid expansion of industrial energy demand. industry in Turkey is energy intensive.   ( http://www.planbleu.org/publications/atelier_energie/TR_Summary.pdf )  
  • Slide content borrowed from Richard Kidd, FEMP President Obama has set a goal of an 83% reduction in carbon emissions by 2050. Requires agencies to: Set GHG reduction targets Develop Strategic Sustainability Plans and provide in concert with budget submissions Conduct bottom up Scope 1, 2 and 3 baselines Track performance
  • Challenges in terms of the need for EE also present the biggest opportunities for significant improvement. Two of major challenges the Alliance has identified as we have worked with municipalities around the world are: Water systems: Treatment and supply of drinking water, distribution systems, wastewater treatment Energy often highest cost associated with water supply Whenever water is lost to leaks, also lost are the energy -- and cost of energy -- embodied in that water, from pumping, treating, and moving the water. INFRASTRUCTURE: Same challenges are faced in municipalities around the world: - Buildings: inefficient appliances/equipment, poor insulation and windows, inefficient heating systems. Often there is no incentive to save energy since there is no metering – of water or energy – to show how much energy is being used or track savings. Municipal governments continue to purchase inefficient equipment (efficiency is not taken into account in purchasing decisions) In addition to building infrastructure, other energy-using components of the municipal infrastructure present great opportunities for increasing efficiency: One of the key ones is street lighting. [Incandescent or Mercury Vapor to: High pressure sodium, Metal Halide, Fluorescent (but poor optical control)[
  • In this arid region in Northeast Brazil, saving water is probably more important than saving energy. PROBLEMS:     Many poor households were not connected to clean, running water.     The water utility was highly inefficient with both water and energy … and it needed to reduce its energy costs and water losses in order to continue to provide service. PROJECT:  A multi-disciplinary team was assembled to focus on ways to reduce energy and water waste throughout the distribution system. Approaches included improving data collection and analysis, automating pressure controls, centralizing pump system controls, renegotiating energy supply contracts, installing capacitors and replacing or re-winding motors. The RESULTS really illustrate what water efficiency is capable of producing: the utility saved 88 million kWh over the course of 4 years, in spite of the fact that water service was expanded to a remarkable 88,000 households who formally had no access to piped water. The project saves the utility $2.5 million every year, with a payback of only 7 months.
  • Develop sufficient legal and regulatory framework Create incentives for promoting energy efficiency Opening the energy sector to private participation Promoting metering and DSM measures Eliminate subsidies and bring energy tariffs to cost-recovery levels Modernize energy standards and technical regulations Promoting energy efficiency services market (The photo is of people getting training in a cold room in Russia; note the coats and hats.)
  • Build institutional capacity and raise awareness Strengthen national agencies for setting energy efficiency targets, developing programs and ensuring implementation Prepare energy managers and auditors for all bulk energy consumers Cultivate partnerships among energy consumers, service providers, financiers. Test EE models, document case studies, prepare guidelines, advocate. Develop adequate financing mechanisms Loan funds, credit guarantees, vendor credits, leasing, carbon finance, etc.
