Energy Options
1760’s Start of Industrial RevolutionJames Wattperfected the steam enginewood and coal first fuel for the steam engine
Mechanical energy was made available to humans in great amounts. With the introduction of fossil fuels, and advent of nuclear energy and modern technology.Advanced rapidly in developing countries.
Conservation of Energy shift from using traditional
renewable sources (human and animal power) to coal, oil, natural gas.
Invention of new mechanical devices and the development of industrial processes with much improved energy efficiency allowed this trend to happen much more easily.
Thomas Edison1879
-made by carbonized cotton filament but burn too quickly
Compact fluorescent lamp provide more light but consume less energy.
In recent times, global demand for energy increase because of the pressures of industrial development.
Primary Energy SourcesFuel Advantages Disadvantages
Biomass
Fuel woodEasily available in less develop countries
Gathering contributes to deforestation and erosion
Ethanol Renewable, cleanerFuel requirement competes with food
Methanol Sources material is waste
Less economical production; cannot be mixed with gasoline
Methane Obtained from waste Not transportable
Pyrolysis gasObtained from waste
Technology is not yet well developed.
Primary Energy Sources
Fuel Advantages Disadvantages
Fossil fuels Oil products
Technology is well developed; Cheaper, transportable, can be stored
Great environment risk during production, refining, transporting, and utilization
Coal Large amount of reserves; can be stored and transported
Mining and usage produce adverse environmental effects; less convenient to use
Natural gas Cleanest of all fossil fuels; can be transported by pipelines; can be transported liquefied
Localized source; risky when transported
Primary Energy Sources
Fuel Advantages Disadvantages
Peat Less expensive gasification produces more gas.
Not available in the Philippines
Oil shales Oil reserves several times larger than conventional oil
Huge disposal problem during production; less economical production
Tar sands Large reserves Poor extraction (5-10% only); high investment cost
Thank you for listening..
