Today, the world as we know it depends on non-renewable energy sources such as oil, natural gas, fossil fuels and coal. Fossil fuels currently provide more than 85% of all the energy consumed in the United States, which is nearly two-thirds of our electricity, and virtually all of our transportation fuels. Oil may be an easy way for us to get energy, but the oil supplies will not last forever and our addiction to oil is the cause of global warming. By switching to alternative energy it will cut back on greenhouse gas emissions and it will provide an clean energy that will always be dependable.
