Present Global Energy use:•, •, •, •, , Energy consumption in developing countries is only one-tenth of that in the developed countries., Coal and natural gas were the most used energy fuels for generating electricity., The world's electricity consumption was 18,608 TWh in 2012., In 2018 the total world energy came from 64% fossil fuels, 10 % nuclear and 10 % renewable (hydro, wind,, solar, geothermal)., , Reff:https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.powermag.com, Page 5, , Maharashtra State Board of Technical Education, , 21 October 2021

Global energy future demands, ►, ►, , 1., , •, •, , World primary energy demand increase by 1.6% per year on an average., The Energy Information Administration (EIA) recently released it latest International Energy, Outlook (IEO), its forecast from 2012 out to 2040 is as follows:, Demand of Oil, is the most important and most highly consumed source of energy in the world., The demand of oil in 2040 will be increase from 85 million barrel to 106 million barrel per day, , 2. Demand of Coal, •, It is the second most abundant source of energy in the world and is highly used in power generation., •, Coal ranks quite low in terms of consumption. Its demand increases to 26 %, https://www.globalenergyinstitute.org/future-global-energy-demand-and-away, , Page 6, , Maharashtra State Board of Technical Education, , 21 October 2021

Global energy future demands, 3. Demand of Natural gas, •, It has been the energy source with highest rates of growth in recent years., •, Consumption of gas has increased to 22%., 4. Demand of Renewables:, •, The demand for renewable energy will more than double by 2040, largely backing out coal., •, Hydroelectric power will remain the largest single source of renewable energy, accounting for about half, of renewable electricity output in 2040., 5. Demand of Nuclear power:, •, Nuclear power is forecast to grow 87%., •, Its overall share of demand, however, is expected to move from a bit more than 4% in 2012 to not quite, 6% in 2040., 6. Demand of other energy sources, •, World electricity demand increase at a rate of 2.5%., •, Transportation energy consumption increases by nearly 40% between 2018 and 2050, https://www.globalenergyinstitute.org/future-global-energy-demand-and-away, , Page 7, , Maharashtra State Board of Technical Education, , 21 October 2021

Energy conservation, ►, •, , •, , •, , WHY TO CONSERVE IT ?, We have limited resources available on earth and our demands are, continuously increasing day by day., It is possible that someday most of the non- renewable resources will be, exhausted hence it is necessary to save non-renewable energy resources., Energy conservation increases national, personal and financial security., , We save our money when we save energy., Page 8, , Maharashtra State Board of Technical Education, , We reduce pollution when we save energy., 21 October 2021

What We Can Do at Global Level?, Energy Strategies For A Sustainable World, ►, , Necessary condition for socio-economic change, , to lead to a sustainable world must include:, • Satisfaction of basic needs of the peoples, • Economic viability, • Self reliant interdependence of nations, • Harmony with the environment, Energy strategies for future can be classified as:, 1. Immediate, 2. Mid-term, 3. Long term, ►, , Page 10, , Maharashtra State Board of Technical Education, , 21 October 2021
Page 11 :
Energy Strategies For A Sustainable World, Immediate term strategy:, • Optimum utilization of existing assets., • Efficiency in production system & reduction in distribution losses., • Promoting R&D, transfer and use of technologies for environmentally sound energy systems., •, Rationalizing Tariff structure of all energy products., ►, , Medium-term strategy:, • Demand management through conservation of energy, structural changes in economy, model mix in, transportation sector, recycling, • A shift to less energy-intensive modes of transport, • Shift to renewable sources of energy., ►, , Page 11, , Maharashtra State Board of Technical Education, , 21 October 2021
Page 12 :
Energy Strategies For A Sustainable World, Long – term strategy, • Efficient generation of energy resources., • Improving energy infrastructure, • Creation of urban gas transmission and distribution network., • Improving energy efficiency in accordance with national, socio-economic & environmental priorities., • Promoting of energy efficiency & emission standards., • Programs for adopting energy efficient technologies in large industries., • Deregulation and privatization of energy sector, • Streamlining approval process for attracting private sector participation in power generation, transmission &, distribution., ►, , Page 12, , Maharashtra State Board of Technical Education, , 21 October 2021
