Alternative energy is an interesting concept when you think about it.
In our global society, it simply means energy that is produced from sources other than our primary energy supply: fossil fuels.
The total world energy demand is for about 400 quadrillion British Thermal Units — or BTUs — each year (Source: US Department of Energy). A BTU is roughly equal to the energy and heat generated by a match.
Oil, coal and natural gas supply nearly 88 percent of the world’s energy needs, or about 350 quadrillion BTUs.
Love-hungry teenagers and archaeologists agree: dating is hard.
Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.This is when most of the major groups of animals first appeared on Earth.The later fossil fuels — which provide more substandard fuels like peat or lignite coal (soft coal) — began forming as late as five million years ago in the Pliocene Period.Still, nuclear energy is not likely to be a major source of world energy consumption because of public pressure and the relative dangers associated with unleashing the power of the atom.Yet, governments such as the United States see its vast potential and are placing pressure on the further exploitation of nuclear energy.
It’s not so much that we mine fossil fuels for our consumption any more than it is to mine salt or tap water supplies way underground.
