發(fā)布:2024/5/23 20:38:36組卷:12引用:6難度:0.72375.Clean energy may also be called renewable energy or green energy,and it specifically refers to energy produced from renewable resources without creating environmental debt.There are several other ways that this term can be explained,however.It may refer to energy processes that pollute less or,alternately,to energy that doesn't pollute at all and doesn't use resources that can't be easily renewed.The basic forms of clean energy are often referred to as those that come from water,wind,or sun.
It's hoped that by using this type of energy,especially as a total substitute for use of things like oil,might help to reduce global warming and greenhouse gas emission,creating a safer planet for all people.In reality,clean energy has its problems too,which have not been fully realized because it is not a complete replacement for energy created by non-renewable resources.For instance,wind farms that can provide power may have significant effect on local bird populations,and birds of some types can face serious reduction of numbers when they live near wind farms.
Nevertheless,these negative consequences tend to be relatively small in comparison to the use of oil or non-clean coal.Many environmentalists reason that,though no power source is completely without risk,green energy could have a wide-reaching effect on healing the planet and perhaps stopping the tide of global warming.An additional reason why it can be so desirable is because it tends to come from sources that are free.While controlling this energy costs money,wind and sun aren't owned by anybody in particular.Otherwise,political problems may be created and wars may be fought for a certain resource.For example,most
of the oil in the world is gathered in a few places,and the majority is located in the Middle East.So they believe that wind or solar energy could lead not only to a cleaner planet,but also a more peaceful world.
Much remains to be done to figure out how to best control renewable energy sources and how to use them to their best advantage.One issue is how to transport collected energy from one place to another,since many places that produce this energy are located in remote locations.Changing the power net to adapt to
different sources of energy can help this problem,but this has yet to occur on a wide scale.
