石油是非可再生资源，随着各国经济的发展，他们对石油的依赖也在不断增强，

Oil is a non renewable resource, as economies develop, their dependence on oil has also been enhanced to increase the development and utilization of oil, at the same time, we should also see that the countries also increased for other energy sources research and development, such as: solar, wind, tidal, wave and bioenergy. However, these techniques are not very mature, it is the alternative to oil really is no good way, at least in the foreseeable twenty or thirty years time, oil will still be the main source of energy used by the transport industry, but it should be noted with the development of alternative technologies related to the proportion of oil in the transport industry, which will be occupied by lower and lower.

Oil is a non-renewable resource, with the development of the economy, their dependence on oil is also increasing, increased the development and use of oil, at the same time, we should also see that countries have also increased research and development of other energy sources, such as: solar, wind, tidal, wave energy and bioenergy. However, these technologies are not very mature, people currently replace oil is really no good way, at least in the expected twenty or thirty years, oil will still be the main energy used in the transport industry, but it should also be seen that with the development of related alternative technology, the proportion of oil in the transport industry will be less and less.

Oil is a non renewable resource. With the economic development of all countries, their dependence on oil is also increasing, increasing the development and utilization of oil. At the same time, we should also see that all countries have also increased the research and development of other energy sources, such as solar energy, wind energy, tide, wave energy and bioenergy. However, these technologies are not very mature. There is really no good way for people to replace oil at present. At least in the expected 20 to 30 years, oil will still be the main energy used in the transportation industry. However, it should be noted that with the development of relevant alternative technologies, the proportion of oil in the transportation industry will be lower and lower.
