Energy Management - Part 1

THE CONSUMPTION OF ENERGY

Most "modern" architecture, transportation, and food production was created upon, and is dependent on, the assumption that using fossil fuels for energy is economical and that their supply is inexhaustible. Few people are aware of the true costs associated with the overuse of fossil fuels. Mining that displaces habitats, forest cover, and farmland; oil spills that foul beaches, marine environments, and groundwater; and air pollution that reduces the chances for species survival are difficult to associate with flipping on a light switch, running an air-conditioner, or driving a car.

In reality, unchecked consumption of the finite fossil fuel reserves drives more and more exploration and extraction at a higher economic cost, and displaces more and more natural resources at a higher environmental cost. A compounding reality is that generating energy by burning coal, oil, and natural gas is a major source of atmospheric contamination responsible for global warming and climate change, acid rain, and smog. The resulting impact damages water bodies and groundwater, soils, crops, wildlife and wildlife habitat, building materials, and mankind's personal health. The combined effect is the inability to sustain life. Thus, the true cost of using fossil fuels for highly consumptive energy needs is not just the price humans pay, it is also the price the environment pays.

ALTERNATIVE ENERGY SOURCES

Just as a site has primary natural and cultural resources, it has primary renewable energy resources, such as sun, wind, and biogas conversion. Solar applications range from hotwater preheat to electric power production with photovoltaic cells. Wind-powered generators can provide electricity and pumping applications in some areas. The biogas conversion process reduces gas or electricity costs and eliminates the release of wastewater effluent into water resources. With known technologies the intelligent use of primary renewable energy resources can benefit any development.

The availability, potential, and feasibility of primary renewable energy resources must be analyzed early in the planning process as part of a comprehensive energy plan. The plan must justify energy demand and supply and assess the actual costs and benefits to the local, regional, and global environments.
