At present fossil fuels are the most important sources of energy. In many countries most of the energy is still generated by nonrenewable sources, which are represented by a limited reserve coal, oil, and gas. They will become scarce and therefore prohibitively expensive after a few decades. ...
"Today, 27 years later, the share of the world's total energy provided by fossil fuels is 81 percent" as well, he said. The statistics "illustrates our collective failure to address climate change," he said. "Coal use is up 68 percent. Oil use is up 36 percent. Natural gas use is ...

解析 C。中文解析:文中提到“Renewable energy sources such as solar and wind power are becoming more accessible and efficient, offering a sustainable alternative to fossil fuels”,即可再生能源如太阳能和风能正变得更容易获取和高效,为化石燃料提供了一种可持续的替代方案。
fossil fuel is burned, it pollutes the air.以及Another problem is that we're running out of it.这是说明矿物燃料的缺点,而第二段开头A big source of energy for many countries is nuclear power ,可知需要引导处新能源.所以That's why we need new sources of energy.可以放到第一段的后面.故选A....
Renewable energy, also known as alternative energy, can be gained from such non-fossil sources as wind, sun and wave. The overwhelming majority of the world's energy supply is still derived from fossil fuels now, say coal and natural gas, which are scarce resources. But according to a new...
Firstly, fossil fuels - coal, oil, and natural gas - have long been the primary sources of energy for humanity. Extracted from beneath the earths crust over millions of years, they contain high amounts of stored solar energy, transformed into a concentrated and easily accessible form. Despite...
