Of this amount, oil is king, providing about 41 percent of the world’s total energy supplies, or about 164 quadrillion BTUs.Coal provides 24 percent of the world’s energy, or 96 quadrillion BTUs, and natural gas provides the remaining 22 percent, or 88 quadrillion BTUs.Certainly, if there were a way that fossil fuels can be mined and used in ways that do not harm our ecology, then everything will be okay… What makes our world perfect is that, it really isn’t perfect according to definition.
Solar energy, wind power and moving water are all traditional sources of alternative energy that are making progress.The enthusiasm everyone shares for these developments has in many ways created a sense of complacency that our future energy demands will easily be met.Coal, oil and natural gas are the three kinds of fossil fuels that we have mostly depended on for our energy needs, from home heating and electricity to fuel for our automobiles and mass transportation. They are limited in supply and will one day be depleted. Fossil fuels formed from plants and animals that lived hundreds of millions of years ago and became buried way underneath the Earth’s surface where their remains collectively transformed into the combustible materials we use for fuel.In fact, the earliest known fossil fuel deposits are from the Cambrian Period about 500 million years ago, way before the dinosaurs emerged onto the scene.In the Arctic and Antarctica, warmer temperatures are causing the ice to melt which will increase sea level and change the composition of the surrounding sea water.
Rising sea levels alone can impede processes ranging from settlement, agriculture and fishing both commercially and recreationally.This means that fossil fuels, along with nuclear energy — a controversial, non-renewable energy source — are supplying 93 percent of the world’s energy resources.Dams are a major source of hydroelectric energy, such as the Hoover Dam on the Colorado River (pictured).It’s not so much that we use fossil fuels for energy that is problematic, but it’s the side effects of using them that causes all of the problems.Burning fossil fuels creates carbon dioxide, the number one greenhouse gas contributing to global warming.Harnessing its energy holds great promise for the world’s energy needs, and it will be heavily called upon as fossil fuels are depleted.
