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
