Energy and Public Lands

The United States boasts substantial energy resources?Federal lands provide。good deal of US energy
production,the US Department of the Interior manages federal energy leasing(租赁),both on land and on
the offshore Outer Continental Shelf. Production from these sources amounts to nearly 30 percent of total
annual US energy production.
In 2000,32 percent of US oil,35 percent of natural ga9,and 37 percent Of coal were produced from
federal lands,representing 20,000 producing oil and gas leases and 135 producing coal leases.Federal lands
are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74 percent of
undiscovered natural gas.
Revenues from federal oil,gas,and coal leasing provide significant returns to US taxpayers as well as
State government,In 1999,for example,$553 million in oil and gas revenues were paid to the US Treasury,
and non-Indian coal leases accounted for over $304 million in revenues, of which 50 percent were paid to
State governments,Public lands also play a critical role in energy delivery.Each year,federal land managers
authorize rights of way for transmission lines,rail systems,pipelines,and other facilities related to energy
production and use.
Alternative energy production from federal lands falls behind conventional energy production,though the
amount is still significant. For example , federal geothermal (地热)resources produce about 7. 5 billion
kilowatt-hours(千瓦时)of electricity per year , 47 percent of all electricity generated from US geothermal
energy.There are 2,960 wind turbines on public lands in California alone,producing electricity for about
300 ,000 people. Federal hydropower(水电)facilities produce about 17 percent of all hydropower produced
in the United States.
Because of the growing US thirst for energy and increasing public unease with dependence on foreign oil
sources,pressure on public lands to meet US energy demnand is becoming more intense.Public lands are
available for energy development oniy after they have been evaivated through the land use planning process.
If development of energy resources conflicts with management or use of other resources,development restric-
lions or impact moderation measures may be enforced,or mineral production may he banned altogether.

Ceothermal resources,wind turbines,and hydropower facilities in Paragraph 4 are cited as examples to illustrate that______.
A:alternative energy production is no less than conventional energy production
B:the amount of alternative energy production from public lands is huge
C:they are the most typical conventional energy resources from public lands
D:geothermal reoourceg are more important than the other two

共用题干第一篇Renewable Energy SourcesToday petroleum(石油)provides around 40% of the world's energy needs, mostly fuelling automobiles.Coal is still used,mostly in power stations,to cover one-quarter of our energy needs,but it is the least efficient,unhealthiest and most environmentally damaging fossil fuel(矿物燃料).Natural gas reserves could fill some of the gap from oil,but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years.Less-polluting renewable energy sources offer a more practical long-term energy solution."Renewable"refers to the fact that these resources are not used faster than they can be replaced.Hydroelectric(水力发电的)power is now the most common form of renewable energy,suDDIvina around 20%of world electricity.China's Three Gorges Dam is the largest ever. At five times the size of the US's Hoover Dam, its 26 turbines(涡轮机)will generate the equivalent energy of 18 coal-fired power stations.It will satisfy 3% of China's entireelectricity demand.In 2003. the first commercial power station to use tidal(潮汐的)currents in the open sea opened in Norway. It is designed like windmill(风车),but others take the torm ofturbines.As prices fall,wind power has become the fastest growing type of electricity generation一quadrupling(翻两番)worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity.Though it will be more expensive,there is more than enoucih wind to provide the world's entire energy needs.Wind farms come in onshore and offshore forms.They can often end up at spots of natural beauty,and are often unpopular with residents.And turbines are not totally harmless一they can interfere with radar, alter climate and kill sea birds.Scotland is building Europe's largest wind tarm,wnicn will power 200.000 homes.The UK's goal is to generate one-fifth of power from renewable sources,mainly wind,by 2020.But this may cause problems,because wind is unreiiable.According to the passage,which of the following is the most polluting energy resource?A:Petroleum. B:Coal.C:Natural gas. D:Water.

Federal hydropower (水电)facilities produce about 17 percent of all hydropower produced in the United States.Because of the growing US thirst for energy and increasing public unease with depend-ence on foreign off sources,pressure on public lands to meet US energy demand is becoming more intense. Public lands are available for energy development only after they have been evaluated through the land use planning process.If development of energy resources conflicts with management or use of other resources,development restrictions or impact moderation measures may be enforced,or mineral be banned altogether.Geothermal resources,wind turbines,and hydropower facilities in Paragraph 4 are ci-ted as examples to illustrate that______.A: alternative energy production is no less than conventional energy productionB: they are the most typical conventional energy resources from public landsC: geothermal resources are more important than the other twoD: the amount of alternative energy production from public lands is huge

Passage FourHow can we get rid of garbage?Do we have enough energy sources to meet our future energy needs?These are two important questions that many people are asking today.Some people think that man might be able to solve both problems at the same time,They suggest using garbage as an energy source,and at the same time it can save the land to hold garbage.For a long time,people buried garbage or dumped it on empty land.Now,empty land is scarce.But more and more garbage is produced each year.However,garbage can be a good fuel to use.The things in garbage do not look like coal,petroleum,or natural gas;but they are chemically similar to these fossil fuels.As we use up our fossil-fuel supplies,we might be able to use garbage as an energy source.Burning garbage is not a new idea.Some cities in Europe and the United States have been burning garbage for years.The heat that is produced by burning garbage is used to boil water.The steam that is produced is used to make electricity or to heat nearby,buildings.In Paris,France,some power plants burn almost 2 million metric tons of the cities garbage each year.The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited.Burning garbage might be one kind of energy source that we can use to help meet our energy needs.This method could also reduce the amount if garbage piling up on the earth.The best title for the passage may be______A.Garbage and the EarthB.Fossil Fuel and GarbageC.Land and GarbageD.Garbage?Energy Source

Text 2 While fossil fuels—coal,oil,gas—still generate roughly 85 percent of the world’s energy supply,it's clearer than ever that the future belongs to renewable sources such as wind and solar.The move to renewables is picking up momentum around the world:They now account for more than half of new power sources going on line.Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources.But increasingly the story is about the plummeting prices of renewables,especially wind and solar.The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.In many parts of the world renewable energy is already a principal energy source.In Scotland,for example,wind turbines provide enough electricity to power 95 percent of homes.While the rest of the world takes the lead,notably China and Europe,the United States is also seeing a remarkable shift.In March,for the first time,wind and solar power accounted for more than 10 percent of the power generated in the US,reported the US Energy Information Administration.President Trump has underlined fossil fuels—especially coal—as the path to economic growth.In a recent speech in Iowa,he dismissed wind power as an unreliable energy source.But that message did not play well with many in Iowa,where wind turbines dot the fields and provide 36 percent of the state’s electricity generation—and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.The question“what happens when the wind doesn’t blow or the sun doesn’t shine?”has provided a quick put-down for skeptics.But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.The advance is driven in part by vehicle manufacturers,who are placing big bets on battery-powered electric vehicles.Although electric cars are still a rarity on roads now,this massive investment could change the picture rapidly in coming years.While there’s a long way to go,the trend lines for renewables are spiking.The pace of change in energy sources appears to be speeding up—perhaps just in time to have a meaningful effect in slowing climate change.What Washington does—or doesn’t do—to promote alternative energy may mean less and less at a time of a global shift in thought.It can be inferred from the last paragraph that renewable energy____A.will bring the US closer to other countriesB.will accelerate global environmental changeC.is not really encouraged by the US governmentD.is not competitive enough with regard to its cost

Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system. The conservation of energy through architectural(建筑学的)design becomes, itself, a green energy source. Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source.4.One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology,where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects.The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient,but by being cost efficient as well.Paragraph 3______A:Why Do We Develop Green Energy?B:What Is the Goal of Green Energy?C:What Is the Weakness of Green Energy?D:What Is a Green Energy?E:How Much Does the Green Energy Cost Every Year?F: How Many Kinds of Green Energy We Can Take Use of?
