Frequently Asked Questions

gt; If the only long-term solution is to replace fossil fuels, where will our energy come from?

what's up with the weather: frequently asked questions
There are forms of energy which produce little or no carbon. However, currently, there is no known source (with the possible exception of nuclear energy capable of producing the massive amounts of energy the world will need. Hydroelectric power is essentially carbon free, but the available rivers have all been exploited and hydro will never contribute more a few percent of the total.

How much of our energy comes from fossil fuels?

FREQUENTLY ASKED QUESTIONS
More than 85 percent of the energy used by the United States comes from fossil fuels. Oil supplies about 40 percent of our energy; natural gas provides about 25 percent, while coal provides about 20 percent.

Why do we need to use fossil fuels for energy?

FREQUENTLY ASKED QUESTIONS
First, the United States has enough fossil fuels - especially coal and natural gas - to provide energy for decades and possibly, for centuries. At the rate we currently use coal, for example, this country has enough to last for more than 250 years. There is enough natural gas to last until well after the year 2060, possibly enough to last for a hundred years or more. There is even a lot of oil left in the ground, even though the United States produces only half of the oil it uses.

gt; To control greenhouse gas emissions, do we have to phase out fossil fuels?

what's up with the weather: frequently asked questions
Sooner or later, yes. Because CO2 stays in the atmosphere for about a century, simply freezing the annual emissions won't stop the atmospheric concentrations rising. To stabilize the atmospheric levels of CO2, be it at double, triple, quadruple preindustrial levels (or more), will eventually involve phasing out fossil fuels entirely. This is extraordinarily difficult.Fossil fuels are the basis of modern urban civilization.

gt; What are the challenges in cutting our dependence on fossil energy?

what's up with the weather: frequently asked questions
Perhaps the biggest challenge is to cut our dependence at a time when the world's population and energy demands are both rising rapidly. Over the next century, world population will almost double to over 10 billion at least. And the standard of living of billions of people will rise as they seek many of the material benefits of the developed nations.

What do we use fossil fuels for?

FREQUENTLY ASKED QUESTIONS
Fossil fuels touch every moment of our lives - when we wake up or sleep, when we eat, when we use our eyes to see, when we play or work, or when we are ill. For example, oil not only can be refined into fuels, such as gasoline, to power engines, it can also be processed into petrochemicals from which plastics, medicines, paints, etc. can be made.

Are there alternatives to fossil fuels?

Researching Middle School Debate Topics
This is an answer from a scientist to the question of alternatives to fossil fuels. The opposition could use this to support several of their arguments This is an article from Science Daily. It argues that fossil fuels can be replaced by microorganisms. This is a great graph from the Christian Science Monitor that shows all the alternatives to fossil fuels. It will be useful for the proposition team. This comes from the department of energy.

Are Alternative Fuels the Answer to the Problem of Fossil Fuels?

Darren Williger - EzineArticles.com Expert Author
News-and-Society:Environmental] Fossil fuels are the current source of most of the energy that vehicles today are powered by. Unfortunately, fossil fuels are associated with pollution problems and problems of rising costs. This article explores alternative fuels as an answer to the problems posed by fossil fuels. Self-Improvement:Spirituality] According to karma and Hinduism, whatever you do, you find that the universe is with you and is always around for you.

Will there still be a market for hydrocarbon fuels in the New Energy Age?

New Energy FAQ
In the New Energy Age, there will still be a market for hydrocarbon substances (oil, natural gas, even coal), at least for a time. These will be used in the chemical industries to make plastics and in many other industrial processes in which these substances have value as feedstocks.

Why is Practical Action supporting the use of fossil fuels?

Practical Action - Key questions answered
Practical Action recognises that there may be environmental concerns about swapping to cleaner fuels such as liquid petroleum gas, as it is a fossil fuel and therefore emits greenhouse gases. However liquid petroleum gas will generally produce less greenhouse gases than wood being burnt very inefficiently on a three stone fire. However the environmental impact must be balanced with the health impact.

How do grass pellets compare economically to fossil fuels?

GrassBioenergy.org: Frequently Asked Questions
As of now, we do not have any economic comparisons of cool-season grass pellet systems with fossil fuels. REAP-Canada has made some comparisons of switchgrass with fossil fuels and estimated that switchgrass may be economically superior to all but natural gas. As the price of natural gas continues to climb, grass pellets will ultimately be cheaper than natural gas, if that has not already happened.

What is the main advantage of hydrogen compared to fossil fuels?

Answer: No, the operation would be similar to an oil rig where the 24/7 crew handles all maintenance and receives supplies from transport ships or helicopter.

CAN THE WORLD SURVIVE WITHOUT FOSSIL FUELS? WHAT ARE THE ALTERNATIVES?

Climate Crisis FAQ
It is becoming apparent that the world may not be able to survive with fossil fuels. This means that we must develop renewable sources of energy which are environmentally sustainable. Fortunately, we already posses the technology at hand to provide clean and reliable sources of energy for meeting human needs. Renewable systems include solar photo voltaic power systems, solar hot water systems, wind turbines, bio-fuel plantations, hydroelectric systems and so on.

What are the non-climate costs of using fossil fuels?

Carbon Tax Center & FAQs
Fossil fuels impose a multitude of environmental and social costs apart from destabilizing climate. Chief among them are "traditional" air pollution such as car and truck exhaust and smokestack emissions; damage to land and water from extracting and transporting fuels; and the militarism, income inequality and political authoritarianism that is evidently endemic to extractive economies (e.g., Saudi Arabia, Nigeria, Indonesia).

Where does the term "Blimp" come from?

Airship FAQ
The popular story is that during World War II, a military general visited one of the many airship stations operated by the U.S. Navy. Trying to find out what material an airship was made from, he tapped his finger against the fully pressurized envelope of a non-rigid Navy airship. The general described the sound he heard, "blimp," and blimps have been called blimps ever since.

Where did the term cookies come from?

The Unofficial Cookie FAQ
Lou Montulli, currently the protocols manager in Netscape's client product division, wrote the cookies specification for Navigator 1.0, the first browser to use the technology. Montulli says there's nothing particularly amusing about the origin of the name: 'A cookie is a well-known computer science term that is used when describing an opaque piece of data held by an intermediary. The term fits the usage precisely; it's just not a well-known term outside of computer science circles.'"

Go to Rustoboro City and go to the Devon Building (where you got the PokeNav). Take it to the scientist on the far right on the second floor. The Claw Fossil gives you a lv20 Anorith, while the Root Fossil gives you a lv20 Lileep

How responsive is energy demand to the price of fuels?

Carbon Tax Center & FAQ
That varies with the type of fuel, the expected persistence of the price change, and the availability of substitutes. The two forms of energy that economists have studied most intensively are gasoline (which accounts for 22.9% of U.S. emissions of carbon dioxide) and electricity (39.5% of CO2). From our literature review, CTC believes a "price-elasticity" of 40% (or negative 0.4, in the jargon) is an appropriate assumption for gasoline demand, and 70-75% for electricity.
