The arrowhead, which was previously buried in the soil popped to the surface.

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.
