Future Energy and Environment M Tamim PMRE Dept, BUET mdtamim@yahoo.com
The Need of the Time(Before the next major break through) • Improve efficiency • Conserve energy • Increase use of renewable • Increase use of Nuclear • Innovate • Manage carbon
The efficiency game • USA Data • Buildings use 73% electricity (40% of total energy) • 25% to 30% improvement possible • Industries can reduce by 14% to 20% • Transport • Present light vehicle millage 25m/gal • By 2030, conventional vehicle will increase to 35m/gal • 20% of US energy comes through efficiency
Conservation • Attitudinal issue • UK group encouraging men urinating in compost dump! • Major awareness campaign • Need! Not Greed • Gain must not be replaced by larger machines or more luxury • No realistic estimate of saving
Renewable (all about land) Year around day night average electricity production Present world average requirement is 0.1w/m2
Innovation? All focused on carbon neutral power production and improved efficiency! • Solar devices with trapped sunlight • Small low speed wind turbines • Nano-technology • Carbon capturing in limestone • Trap power in high wind by kite type turbine • Solar flower tower • Power from bridge, road and moving cars • Solar satellite power • Splitting water w/o chemicals • Nuclear Fusion • Waste, low tidal/current turbines • Improved battery • Carbon to cement
