Your Name Section or Time/Day Date ENVS 1140 Energy Past and Present Assignment Purpose: The purpose of this assignment is to work along with the lecture material to familiarize you with some of the current sources of energy and allow you to think about the options and various environmental impacts associated with those sources. Energy is a human need, and sustainability in energy will require smart choices about where we get energy from and how we do that. Tasks: Respond to the following with a sufficient number of separate well-organized paragraphs. should be able to tell which paragraph(s) are answering which questions Based on the readings from your textbook, the slides, and your class notes, which of the three non-renewable fossil fuels do you see as currently being the most environmentally damaging? Why? Quote and cite any words from an external source. 1. Based on the information from the course or outside sources, do you think it is possible to reduce the impact of this energy source enough for us to continue to use it? If so, how? If not, why? 2. If we discontinue our use of fossil fuels as a source of energy, will their extraction decrease? Consider the history of forest resources and coal as you answer then respond with 1-2 paragraphs. 3. 4. Read the article "Digging into the practice of fracking and respond to the following questions 1) What are the benefits of hydraulic fracturing to provide natural gas? 2) What are the potential hazards? 3) Should we proceed with this technology? 4) why or why not? Criteria: This assignment will be evaluated on the following scale Exceeds Expectations- 35pts Each element of the prompt is clearly addressed and exemplified . Response indicates integrating elements of the course with outside sources and personal perspective Readability and grammar are excellent o

Explanation / Answer

1- Most non-renewable energy sources are fossil fuels:coal, petroleum, and natural gas. Carbon is the main element in fossil fuels.All energy sources have some impact on ourenvironment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.According to the U.S. Energy Information Administration, non-renewable energy sources cannot be replenished in a short period.

Greenhouse gas emissions

Perhaps the most well-known impact of using non-renewable energy sources is the emission of greenhouse gases, in particular CO2 and methane, which contribute to climate change

Air pollution

Non-renewable energy sources are not just altering our Earth’s atmosphere by increasing the amount of greenhouse gas emissions. They also emit a variety of pollutants that are impact people’s health and the environment.  

Acid rain and water pollution

But it is not just the air that we breathe that gets polluted. Dangerous pollutants that are emitted into the air can often follow the water cycle. This is the case of acid rain which is created due to the emission of sulphur and other chemicals into the atmosphere. Because of this cocktail of chemicals, the rain becomes mildly acidic.

2-The main advantages of non-renewable energies is that they are abundant and affordable.

Non-renewable resources include coal, natural gas and oil.

Managing Water. Water is the most abundant natural resource in the world. ...

Reduce, Recycle and Re-use. Recycling and reusing are better alternatives to disposing of some items. ...

Laws and Regulations. ...

Mass Transport and Hybrid Vehicles.

3-yes,extraction will be decrease.at current rates of production, oil will run out in 53 years, natural gas in 54, and coal in 110. We have managed to deplete these fossil fuels – which have their origins somewhere between 541 and 66 million years ago – in less than 200 years since we started using them.

The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Steam coal - also known as thermal coal- is mainly used in power generation.

4-

It is the most efficient way of extracting oil and natural gas from shale rock underneath the surface.
