a) management of renewable resources (water, air, soil, plant life, animal life);
b) management of nonrenewable resources (coal, oil, natural gas, nuclear power, mineral resources);
c) the mitigation of land-use and environmental hazards through preventive measures; and
d) cost/benefit tradeoffs in conservation policies.
6.6 The student will investigate and understand the properties of air and the structure and dynamics of the Earth’s atmosphere. Key concepts include:
d) natural and human-caused changes to the atmosphere;
g) the importance of protecting and maintaining air quality.
6.2 The student will investigate and understand basic sources of energy, their origins, transformations, and uses. Key concepts include
b) the role of the sun in the formation of most energy sources on Earth;
c) nonrenewable energy sources (fossil fuels including petroleum, natural gas, and coal);
d) renewable energy sources (wood, wind, hydro, geothermal, tidal, and solar)
Resources
: something that a country has and can use to increase its wealth : a supply of something (such as money) that someone has and can use when it is needed : a place or thing that provides something useful http://www.merriam-webster.com/
http://www.energy.vt.edu/vept/index.asp sources of VA datahttp://www.thegwpf.com/ interesting site about energy issues
Some of the most easily thought of resources in our lives might be: safe, available water; same of soil/land; same food; safe/clean air; energy such as oil, natural gas, coal, wind, geothermal, nuclear, tidal, solar.
Vintage ad for garbage disposal
1872New York City stops dumping its garbage from a platform built out over the East River.
New York City and garbageExecutive Summary New York City generates approximately 13,000 tons of residential garbage daily. Current disposal methods present economic, environmental, political, and social difficulties. This report presents a new Solid Waste Alternative Technologies Program for New York City that will address these problems.
Current policies discourage landfills and incinerators within New York City boundaries. Since 2001, the City has exported its garbage to locations as far away as Virginia and Ohio. Exportation leaves the City vulnerable to increasing costs because both transportation companies and disposal facilities are privately
owned. The system is politically dangerous because other states are increasingly unwilling to accept the City’s garbage and are seeking legal means of excluding outside garbage. Additionally, both landfilling and incineration pollute the air and groundwater. Finally, emissions from trucks used in transportation are detrimental to human health and the environment.http://www.columbia.edu/cu/mpaenvironment/pages/projects/Final%20SWAT%20Report.pdf
The cost of dumping garbage in the Northeast has increased from $12.66 per ton in 1985 to $69.07 in 2002; the highest tipping fees in the U.S. In 2002, the Mid-Atlantic Region, including Pennsylvania and Virginia, had the nation’s second highest tipping fees at $45.26 per ton, more than doubling since 1985.

California has an extreme drought as of Spring 2015. Lack of rain and Winter snows in the mountains means water usage regulations have begun. Large fines or water cut-offs will be applied to all violaters. Darker colors indicate worse drought problem.
Note: the water reference in the above illustration does not show tidal power and hydropower separately.
Tidal Powerhttp://technologystudent.com/images5/tidal1.gifTides occur every day and are generally observed at the ocean. Water comes in (or rises) as tide change every 12 hours approximately. We experience the opposite low tide just as often, half way between high tides. This flow of water is endless and dependable. Some locations experience massive changes or movements of water while other locations see much less change.
Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity. Tidal power has great potential for future power and electricity generation because of the massive size of the oceans. These articles explore the potential energy of tidal power technologies.
Nonrenewable resources are natural resources that cannot be replaced soon after they are used.
About 92% of the energy consumed in the United States comes from non-renewable energy sources, which include uranium ore and the fossil fuels — coal, natural gas, and petroleum.
Oil (petroleum) Natural Gas Coal Uranium (nuclear)
