In our world today the availability of energy largely depends on fossil fuel availability. These fossil fuels include oil, coal, and natural gas, and fossil fuel consumption constitutes about 80 percent of the total energy production across the globe. The biggest consumers in the world are China, U.S.A., and the European Union, with about half of the total world fossil fuel consumption attributed to them. According to other fossil fuel consumption statistics, it is mostly natural gas and oil that can be used far away from their extraction source, as it is difficult to transport coal for long distances. Fossil fuel consumption statistics also state that trade in fuels accounted for a total of US$715 billion worldwide in 2004.
However, in the more recent years there has been much criticism of the widespread world fossil fuel consumption. As we hear the word “green” more and more, people all across the globe are starting to understand how important it is to replace harmful fossil fuels with energy sources that are clean and renewable. Of course, there is still a fair share of people who don’t believe in global warming and the harmful effects of fossil fuel consumption, but obvious environmental changes and scientific evidence are making a lot of governments take it more seriously.
The country that is currently leading the world in using renewable energy sources is Iceland, which is just a small island in the middle of the Atlantic. They have embraced the use of hydropower and geothermal energy fully, with about 82 percent of their energy consumption delivered from sources that are renewable. Iceland has done an amazing job at weaning itself off the dependence on harmful fuel consumption and replacing it with sustainable renewable energy sources. Sweden is another good example, although not nearly as great as Iceland, with about 25 percent of its energy needs coming from renewable sources.
