SCENARIOS AND RESULTS
Our new results are drawn from a revised set of scenarios involving both key supply and demand-side drivers. The four scenarios we examine are:
• Phase III Reference. A new Reference case, with updated forecasted power sales and base case gas prices, as well as added CHP potential and a refined and expanded portfolio of
DR programs;
• Enhanced Energy Efficiency. The Phase III Reference case with an added portfolio of cost-effective energy efficiency programs;
• Moderate Federal Carbon Policy. The Enhanced Energy Efficiency case with an added requirement that all coal-fired facilities capture and sequester 50% of their CO2 by 2025; and • Strong Federal Carbon Policy. The Enhanced Energy Efficiency Case, but with (a) a rule that all coal-fired plants sequester 90% of their CO2 by 2025; (b) higher natural gas prices due to increased gas demand to replace coal units that cannot cost-effectively sequester
90%; and (c) lower renewable energy costs from more rapid deployment.
Table I-1 summarizes the differences of these four scenarios.

Flower Mound Case Study
736 Words | 3 PagesIn Flower Mound, Texas, residents called upon the state to investigate an alarming spike in the number of children with leukemia, a form of cancer which affects white blood cell production in the body and compromises one’s immune system. In half a dozen Texas counties in the Dallas-Fort Worth area, there were higher rates of invasive breast cancer than anywhere else in the state (Rawlins). Some residents and researchers alike attribute this startling health trend to the natural gas industry and its overwhelming presence in the Lone Star state. In fact, Texas ranks number one in natural gas production nationally, and accounted for nearly thirty percent of all of the US’ natural gas production in 2011 (Davis). Natural gas fracturing or “fracking”

If energy efficiency becomes a more popular trend, people will start lowering their energy usage, and power plants for example, will see differences in the statistics they receive. The statistics should show that less energy is

Husky Energy Case Study
79 Words | 1 PagesAnalyzed Husky Energy financial position and performance using its financial statements for a 10 period and benchmarked Husky Energy to the top 5 oil production companies in Canada, while comparing them to the entire Industry averages. We also researched Husky Energy new ventures and whether the current drop in oil price has increased or decreased oil production. And we concluded by evaluating how the innovative technology of the automobile industry may cause future decline in fuel and diesel consumption.
A Brief Note On Texas Update Production And Consumption
1443 Words | 6 PagesSince Texas is one of the largest producers of wind and solar power, it should encourage the use of renewable energy. If some Texas coal mines and oil drilling were to swap to wind and solar power the overall renewable energy will increase. For instance, “the increase in wind power and the retirement of almost 6,000 megawatts of coal-fired generating capacity, coal-fired power plants supplied 18 percent of state generation in 2021, down from a 36 percent share in 2011.” (U.S. Energy Information Administration, Page 4).5 Due to coal power becoming an outdated energy source, wind power can make a large contribution to the modern world all while being cheaper
The Pros And Cons Of The Keystone Pipeline
1039 Words | 5 PagesIntroduction The Keystone Pipeline was a proposed idea of a pipeline that would run from the oil sands of Canada to Steele City, Nebraska. It would then connect to an existing pipeline that would administer it elsewhere. Since it is an oil pipeline that would cross international borders, it needed the President’s approval. The idea became such a controversial topic when President Obama stated that six days to decide the fate of this project was not a sufficient amount of time to make a decision.

Jfk Assassination Persuasive Speech
1042 Words | 5 PagesFor sheer audacity, nothing beats Kennedy's speech to “...land a man on the moon and bring him safely back to the earth.” He could have said, “We will make the biggest pizza pie the world has ever seen and have every American eat a slice with the Soviet Union watching on live TV,” but that wouldn't have fired up quite the same fires of passion and imagination, or unleashed the tremendous wave of innovation the moonshot did. Looking back, the amazing thing is not accomplishing the safe return a moon landing, but that the nation allowed President Kennedy to make such a commitment. Today a U.S. President must fight with everything he's got, to do much less ambitious things than a moon shot —gun laws and health care. When he gave the “We choose to go to The moon” speech Kennedy said this, “We choose to go to the Moon! ...
Keystone XL Pipeline Research Paper
628 Words | 3 PagesThe US is going to use some source of energy and that will always have some negative effects on the environment. The alternative sources for the energy we need have negative effects on the environment as well. “In 2011 U.S. coal-fired power plants emitted nearly two billion metric tons of greenhouse gases -- roughly eight times the amount produced by mining, refining and burning tar sands”(Biello). Canada is going to develop a pipeline system to export oil whether it’s to the US or other countries, like China, that are trying to get access to this resource.
Arizona Public Services Essay
840 Words | 4 PagesBackground: More than 1.2 million residents in the state of Arizona get their power from Arizona Public Service (APS), a public utility provider (Arizona Public Service, 2023). The corporation manages an extensive portfolio of power plants, some of which are powered by fossil fuels (coal, nuclear, and natural gas), others by renewable resources (solar and wind power), and still others by a combination of these and other energy sources. Nevertheless, APS has been confronting issues connected to costs in recent years. These challenges include increased costs associated with maintaining and operating its old power infrastructure and demand from regulatory authorities to move to greener energy sources (Arizona Public Service, 2023). Challenges:

The Pros And Cons Of Duke Energy
1313 Words | 6 PagesThrough urbanization, modernization, and global energy demands, people abuse the natural environment for the advancement of the human race. Most humans utilize the environment for their benefit only and lack the decency to show respect or concern for their surroundings. Duke Energy, one of the largest energy suppliers in the United States, serves as the major energy source, substantial employer, and economic contributor for North Carolina. Headquartered in Charlotte, North Carolina, Duke Energy provides power to approximately 7.5 million customers throughout the Southeast and Midwest (“Duke Energy”). However, Duke Energy’s coal ash waste ponds are creating disastrous environmental effects (“Coal Ash Contaminates”).
Essay On Nonrenewable Resources
1427 Words | 6 PagesThere is a quote by President Barack Obama saying, “To truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy,” (“151 Inspiring Environmental Quotes”). He believes as many due that nonrenewable resources are harmful to all aspects of life. The energy we use now is harmful to our planet, to humans, and to animals. Scientists are taking steps to making the world a better place. They found sources that replenished naturally in a short amount of time and are less destructive in all aspects.
Electric Vehicles Essay
835 Words | 4 PagesThis evidence helps show that electric vehicles can be more cost effective by three times compared to regular cars. The author also stated that the average electric vehicle can make it forty-three miles from one-dollar worth of electricity. This is about one fourth of the cost of a gallon of regular gas. In IEEE’s article the authors said, “In the next 10 to 20 years, changes in vehicular transportation will be driven by escalating fossil fuel prices,” (Austin Micheal and Russ Lefevre). The writer predicts major changes in the car industry because of the huge surge in gas prices.
