In the future natural resources such as coal and oil will be used or we save on resources? What alternative forms of energy are available In our modern era, many countries are trying to develop and consume natural resources in their factories to manufacture build new goods. Some of those consume oil, coal, and some others use alternative sources such as wind and sun power. A question which is a/the matter of concern is whether oil and coal are more reliable than other new sources. I am, to a great extent of the opinion that the energy crisis is a serious problem and we must replace oil with new energy sources. To begin with, standing at the turn of the new century, we observe that air pollution is one of the most important problems in every big city. Broadly speaking, we must find new energy sources for our community. Some alternative energy sources such as the sun help ? us to charge our cars batteries and cause earth to breathe. To be more specific, these sources of energy do not have combustion., they are cleanr and we can generate electric power more and more. If we develop this new industryial, with the help of technology we can have a beautiful nature with much less no air pollution. As an illustration, many new wind and sun powerhouses in different countries are being built building every year. Of equal importance is the fact that some natural resources such as oil help (helps?) us to generate other chemical materials. Simply stated, if we utilize all of oils for cars we will not be able to produce other chemical products. Another problem, which we are facing with (it?), is energy crisis. The Next generation will need energy sources and we must not use all of them. To be more specific, the amount of these natural resources is are limited and we must replace them with new sources. Energy crisis leads to increasinge prices and it damages to our country's economy. From my perspective, governments must replace fossil fuels with other new energy sources. To recapitulate the reasons, not only does oil combustion cause air pollution, but also if we use them uputilize all of them, the new generation will have no any petroleum to produce new chemical substances and use in cars.
