The world's energy watchdog has sounded the alarm over a"worrying"pause in the shift to clean energy after global investment in renewables fell 7%to$318bn（~240bn）last year.The International Energy Agency said the decline is set to continue int0 2018,threatening energy security,climate change and air pollution goals.Fossil fuels increased their share of energy supply investment for the first time since 2014,to$790bn,and will play a significant role for years on current trends,the IEA said.Investment in coal power dropped sharply but was offset by an uptick in oil and gas spending,the World Energy Investment repoit found..Dr Fatih Birol,the executive director of the IEA,said of the renewables fall:"We are seeing a decrease,which is disappointing.And more disappointing is we see the signs this decline may continue this year-this is a worrying trend."Fossil fuels'share of energy investment needs to drop t0 40%by 2030 to meet climate targets but instead rose fractionally t0 59%in 2017.World leaders'warm words on renewables and energy efficiency needed to be matched with action,Birol said,urging govemments to create less investment uncertainty for green energy.Globally,energy investment fell 2%to$1.8tn in 2017,with electricity taking a bigger share than oil and gas for the second year in a row.The decline in renewable power generation spending was mostly down to falls in wind power and hydro but solar hit record levels despite becoming cheaper to install.While coal investment fell to its lowest level in 10 years,spending on gas-fired power stations rose 40%.Nuclear power fell sharply to the lowest level of investment in five years.In the oil and gas industry,rising prices have helped investment in production rise 4%last year and is expected to grow 5%this year.The US's shale boom will drive much of the groivth,and frackers are on track to achieve positive free cashflow this year,for the first time.The US is not expected to pump enough extra crude to bring down oil prices,though.Birol said"Us shale growth is very welcome growth for badly needed additions but this growth alone will not be enough to balance out the markets.Outside the US,investment in conventional oil and gas projects remains subdued and Birol said the world faced"major difficulties"if investment was not stepped u Motorists spent S 43bn on fully electric cars and plug-in hybrids last year,accounting for half of global growth in car sales.However,the battery-powered cars are not seriously denting oil demand yet the IEA said Governments are increasing investment in energy markets,either directly through state-owned firms or indirectly via investments policies and regulation,which Birol said was a surprising development
The emerging worry about energy is that

A.the current short supply of the clean energy worldwide
B.the failure to transition to renewable energy sources,
C.the decrease of the investment to the energy exploitation
D.people's consciousness of environmental protection

Energy and Public Lands
The United States boasts substantial energy resources. Federal lands provide a 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 gas,and 37 percent of coal were pro-duced 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 undis-covered 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-India 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（许可）rights of way for transmission lines , rail systems , pipe-lines,and other facilities related to energy production and use.
Alternative energy production from federal lands falls behind conventional energy pro-duction , though the amount is still significant. For example , federal geothermal（地热）re-sources 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 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.

Which of the following statements is true of public lands in the U. S.?
A: Half of US energy is produced there.
B: Most of coal was produced from there in 2000.
C: Most energy resources are reserved there.
D: The majority of undiscovered natural gas is stored there.

Passage Four
How 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．

According to the passage,using garbage is______

A.for heating in France each year
B.a new way in a modern society
C.a good way to solve the problem of energy shortage
D.too expensive as an 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 countries
B.will accelerate global environmental change
C.is not really encouraged by the US government
D.is not competitive enough with regard to its cost

Green Energy

1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.
2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. 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?

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.

Greenhouse gases are thought to be causing______.
A:global warming
B:carbon emission
C:lower waste output
D:a green energy source
E:fossil fuels
F: clean fuels

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

Green Energy

1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.
2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. 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.
