Question

1. how do Environmental Pollution, Limited Energy Resources, Uneven Geographical Distribution of Energy, and CO2 Emissions and Climate Change compare in the severity of their impact and cost of their mitigation strategies?

2. Rate the following electricity sources for their contribution to climate change from most to least: biomass, coal, solar, wind, nuclear, natural gas, oil, geothermal, hydroelectric, MSW. Is there any compelling reason not to use any of the carbon neutral (no net carbon emissions) sources?

3. The United States' electricity supply is provided primarily by coal, natural gas, nuclear, and hydropower. How safe are these fuel supplies from interruption by international disasters, weather events or geopolitical tension?

4. How do cultural social norms and values come into play with these types of systems?

Explanation / Answer

1. CO2 emissions, climatic change and the environmental pollution has the most severe impact as compared to the limited energy resources and the uneven geographical distribution of energy because the carbon dioxide emissions greatly affect the climatic change by adding to the green house affect thus causing the environmental pollution by increasing the global temperature. The cost of mitigation strategy of carbon dioxide emissions is through the reduction of green house gas through reducing energy waste and switching to low carbon power source of energy. Out of the other mitigation policies given some are stringent or modest than the 2° C limit

While climatic change including the global warming should be limited to below 2.0 °C relative to the pre industrial level. In case of environmental pollution trees are the most cost effective strategy with a small reduction in NO2 concentrations.

2. Nuclear, Coal, oil, natural gas, geothermal, hydroelectric, solar, wind, biomass, MSW.. No there is any compelling reason not to use any of the carbon neutral sources.

3. Energy security has become a top priority for the United states, approach to energy security the geopolitical tension, energy interdependence and climatic change is been reduced and it is marked safe.

4. Human values play in shaping individuals engagement with environmental issues. The social sciences have been applied to the diverse environmental conservation. Cultural social norms convince populations to support the policies adopted by the government for creating an effective economic stable environment.
