@3J9nL+KC.[Recently, I have been very concerned about international news, and then I get information that the price of crude oil is higher than people can accept. Crude oil is an important kind of fossil fuels and it plays important roles in the process of the development of industrialization and urbanization. Thus many scientists from different countries consider solving this problem through using other renewable resource of energy such as sun, wind or water. Whether these types of energy can substitute for fossil fuels soon? In my point of view it is so hard recently to replace fossil fuels with renewable energy. There are a couple of reasons as follow.

One thing is that, sun and wind energy are scattered in different place and produced at different time, it is hard for us to collect them. When it comes to sun, sunlight only can be available in day but night, so the energy we got is interrupted at night. At the same time, wind resource can not be found in all places in the world, we can just accumulate huge energy of wind in part of countries and even merely partial places in a country. Water has the same problems as sun and wind have. It can only be acceptable in a period of time during a year and just abundant in some places. So these kinds of energy are hardly to replace fossil fuels.

According to a recently report about renewable energy which published on the magazine "Science", keeping these transferred energy in some facilities is difficult to perform, there will be much waste of these energy, and the cost of using these facilities is so high. There will be no country can better manipulating these facilities for a very long following time because these challenges.

Finally, people can not afford the high charge of renewable energy now. Take cars which use renewable energy for examples, the cost of these cars is not tolerable to common workers. There scarcely have been civilians in a country can afford the cost on this kind of cars. Many investigations indicated that people prefer to drive renewable energy cars when the price of gas increase to the level that they can not sustain, however they will run gas cars again when is price of oil is as low as they can pay. As we know, the price of oil is rather lower than renewable energy, so a large number of people choose cars which burn oil as their transportation tools nowadays and subsequent many years.bbs.gter.net,^1?sgU~(xXR
ji5~2b%^6e@Based on the proofs which I stated above, it won't be soon to replace fossil fuels with renewable energy. We only can pay much more attention to technological progresses if we want to see this day's coming as soon as possible.bbs.gter.net F)O\!Eqeb
