Energy Options

1760’s Start of Industrial Revolution James Watt  perfected the steam engine  wood 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 Edison 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 Sources FuelAdvantagesDisadvantages Biomass Fuel wood Easily available in less develop countries Gathering contributes to deforestation and erosion EthanolRenewable, cleaner Fuel requirement competes with food MethanolSources material is waste Less economical production; cannot be mixed with gasoline MethaneObtained from wasteNot transportable Pyrolysis gasObtained from waste Technology is not yet well developed.

Primary Energy Sources FuelAdvantagesDisadvantages Fossil fuels Oil products Technology is well developed; Cheaper, transportable, can be stored Great environment risk during production, refining, transporting, and utilization CoalLarge amount of reserves; can be stored and transported Mining and usage produce adverse environmental effects; less convenient to use Natural gasCleanest of all fossil fuels; can be transported by pipelines; can be transported liquefied Localized source; risky when transported

Primary Energy Sources FuelAdvantagesDisadvantages PeatLess expensive gasification produces more gas. Not available in the Philippines Oil shalesOil reserves several times larger than conventional oil Huge disposal problem during production; less economical production Tar sandsLarge reservesPoor extraction (5-10% only); high investment cost
