根据短文内容,从下框的A---F选项中选出能概括每一段主题的最佳选项.选项中有一项为多余选项.
A.Why to turn to alternative energy?
B.How to use renewable energy?
C.The sources of renewable energy
D.What is renewable energy?
E.Where is the solar energy from?
F.The advantages of renewable energy.
1.( )
When speaking about renewable energy,we are talking about power which gets its energy from resources
which will not be diminished from the use.Renewable energy is a substitute for the non-renewable energy of
fossil fuel.
2.( )
One fundamental advantage of renewable energy,and environmentalists' favorite reason to promote its use,
is that there are no greenhouse gases or other pollutants that give out as there are with the burning of fossil
fuels.Renewable energy,or solar,water and wind power,are certainly not new although they have received
much attention recently because they will not cause pollution.Environmentally friendly power sources such as
wind,solar and water power have been used in both developing and developed countries for a long time
because they are cheap and clean,but they have yet to be used as a primary source of energy for any big
urban area.
3.( )
The generation of power from renewable energy sources has become somewhat more common in recent
times as people have increasingly become aware of issues such as climate change due to fossil fuel byproducts
and the political or social worries about nuclear power.There are numerous countries and non-profit,
environmentally conscious organizations that are supporting the use of renewable energy.
4. ( )
The flow of renewable energy has to do with naturally occurring phenomena.Tides,sunlight,wind and
heat are all created by geothermal events and all are sources of energy.Each of these sources of energy has
unique characteristics related to where and how we can use them.
5.( )
Most technology which transforms renewable energy into power which we can use is solar powered either
directly or indirectly.The atmospheric system of the earth keeps balance so that the heat which spreads out
into space is equal to the amount of radiation received from the sun.The quantity of energy contained in the
atmosphere approximates the earth's climate.The bodies of water of the earth,or its hydrosphere,absorb
much of the radiation which is received from the sun.And much of that absorbed radiation is in the lower
latitudes surrounding the equator.
