Introduction

Traditionally, the United States has relied on fossil fuels with minimal use of alternatives to provide power. The resources appeared to be unlimited and they were found within our borders. As our population has grown and our reliance on power increased, our resources are decreasing. As discussed in Module Environmental Challenges in Energy, Carbon Dioxide, Air and Water , this is particularly true of petroleum oil, which primarily powers transportation. Our electrical grid and transportation infrastructure of roads and highways support these fossil fuel dependent technologies. Fossil fuels store energy well, are available upon demand (not weather dependent), and are inexpensive. However, as we saw in Module Environmental Challenges in Energy, Carbon Dioxide, Air and Water there are many environmental, social, and even economic impacts of using these nonrenewable fuel sources that are not accounted for in the traditional methods of cost accounting. Further, the oil industry has been provided with many subsidies or tax incentives not available to other energy industries.

How do we move to a more sustainable energy economy? We need to pay more attention to the environment, humans, biodiversity, and respecting our ecosystems. It means finding ways to share our resources equitably both now and in the future so all people can have an equal opportunity to derive benefits from electricity, motorized transportation systems, industry, and conditioned indoor environments. At the same time, we must preserve human health and protect the natural world.

Energy use is one big piece of the sustainability puzzle, but it is not the only one. Changing the way we use energy is not easy because of infrastructure, the vision of the American Dream (own a house with a big yard, a big car, independence), changing government policy, lack of economic incentives, etc. Goals need to be set, plans made, and policy set to change the way we use energy. This chapter will discuss some of the commonly held views of where we can start and how we can change.

Climate action planning as a model

Since one of the major sustainability issues is that of climate change and the major cause of climate change is energy use, climate action planning is a valuable framework for examining sustainable energy practices. Greenhouse gas emissions result primarily from our building and transportation energy uses, and they are a measure of the amount of fossil fuels used to provide that energy. They do not directly represent other environmental emissions, although they mostly parallel other air pollutants. Greenhouse gas emissions do not express other ecosystem effects such as land use and water, but this planning allows for economical solutions. A climate action plan provides a roadmap for achieving greenhouse gas reduction targets within a specific timeline and uses a number of strategies.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
