Energy Efficiency

  1.  ‘We can create a more sustainable, cleaner and safer world by making wiser energy choices.’ Robert ALAN  Energy efficiency is fastest, most cost effective remedy to satisfy both power needs and environmental quality concerns.  Renewable energy and clean distributed generation provide cleaner energy that reduce stresses on the electricity grid.
  2.  Energy efficiency increases reliability and supply  ‘Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy’* The Twin Pillars of Sustainable Energy: Synergies between Energy Efficiency and Renewable Energy Technology and Policy".  Energy efficiency is a key requirement for poverty reduction and sustainable development •Efficient energy use is essential to slowing the energy demand growth; clean energy supplies can make deep cuts in fossil fuel use ENERGY EFFICIENCY HELPS ECONOMIC DEVELOPMENT
  3. Environmental Kuznets Curve  The composition of economic activity influences environmental quality.  Income grows, the structure of economy tends to change and gradually increases cleaner activities that produce less pollution.  The share of industry in GDP first rises with economic growth and then declines as the country moves from the pre-industrial
  4. • The process of removing carbon from the atmosphere and depositing it in a reservoir and the primary goal was to keep global warming. • Allow the use of fossil energy to continue, while buying time to make the transition to other energy sources. • CO2 The two basic sequestration options examined were pumping CO2 into the deep ocean and injecting it into underground geological formations. Geological and Oceanic Storage; ocean and atmosphere are constantly exchanging

  11. •A sustainable energy economy requires major commitments to both efficiency and renewables.•Including all renewable energy sources; hydroelectricity, solar energy, wind energy, wave power, geothermal energy, bioenergy, and tidal power. •Making the transition to a more sustainable energy future!
  12. Improve Energy Efficiency Increase fuel efficiency standars for vehicles, buildings and appliances. Offer tax credits for investments in efficiency. Encourage independent power producers. Increase efficiency research and development. Renewable Energy Increase renewable energy to % 40 by 2020. Encourage government purchase of renewable energy devices. Increase renewable energy research and development. Use full cost of accounting and least cost analysis for comparing all energy alternatives. Reduce Pollution Cut Coal use %50 by 2020. Levy Taxes on coal and oil use. Phase out nuclear power or put it on hold by 2020. Phase out nuclear power subsidies.
  13.  China will maintain its increasing demand for oil, coal and gas, and faces a number of challenges in improving its energy efficiency levels  67% of the total primary energy consumption is coal*  China is in the middle stage of industrialization  As a developing country, the Chinese Government has attached high importance to the climate change issue  recent developments in US-China clean energy diplomacy  expect future enhancement of EU- China dialogue on climate change U.S. Energy Information Administration
  14. CONCLUDING REMARKS  Large investment in renewable energy is necessary and predictable policy regime is required.  General understanding of the world energy situation needs to be promoted.  Energy efficiency is also cost-effective opportunity to reduce global greenhouse gas emissions.  Carbon capture and storage may have potential, at least for addressing part of the problem BUT it leaves many environmental problems associated with burning coal unaddressed and may not 16
  15. Under the 12th Five Year Plan (2011-2015), China will continue to raise its investment across a number of green energy sectorsSafe utilization of nuclear power; improving plant performance, and construction. Clean coal technologies  Transportation industries; ‘new fuels, fiscal an financial incentives’ ‘ Renewable power
