Energy is one of the most important concerns in the world today. For years we have had plenty when it comes to energy but the tables are starting to turn. We've come to realize that fossil fuels are limited and at current consumption rates, will be depleted within 100 years. We've also come to realize that the burning of these fuels causes major environmental problems such as air pollution and acid rain. The gases that are released as a result of the burning of fossil fuels also has a tremendous effect on global warming. Eventually, if nothing is done to improve the situation, global warming will effect life in fragile habitats, average global temperatures, and earth's weather systems. The reason we have used these fuels for so long, and continue to use them, is due to the cheap prices of oil, natural gas, and especially coal. In recent years, however, prices for relatively newly developed renewable energy technologies have dropped to near the levels of fossil fuels.
What can be done to satisfy our energy needs without compromising the world in which we live?
Since the early to late 1960's, we have been using nuclear energy. Tremendous energy can be produced when an atom is split in nuclear fusion and at first glance, this technology appears promising. However, upon further examination, we find many problems with nuclear energy. First of all, the price for nuclear produced electricity is far greater than for fossil fuels, (10-15 cents per kilowatt hr. and 3-5.5 cents/kWh). Probably the greatest con for nuclear energy comes in its impact on the environment. Radioactive wastes are produced as a result of creating electricity. These wastes remain toxic for thousands of years, and create a huge storage problem.
Within the last thirty years, renewable energy technologies have found a small foothold in the energy market. Geothermal, wind, solar, and hydro-electric energy are very promising alternatives to fossil fuels and will be needed in the near future, on a large scale basis, to allow us to live the comfortable lives that we're used to. Unfortunately, governments around the world have not embraced these technologies because of loyalties to oil companies. It is plain to see the benefits of an energy reasource like wind over the burning of fossil fuels. The costs for producing electricity with wind are comparable to those of fossil fules, (3.5-7.5 cents/kWh). Perhaps the greatest advantage to using wind and other renewables is the fact that they have limited to no effects on our environment. Solar is essentially harmless and the only problem with wind is a small amount of bird deaths due to flying into the wind turbines. Compare that with the altering of entire ecosystems, contamination of the air we breathe, and the alteration of average global temperatures and weather patterns and it's a no-brainer.
We need to wake up! If we don't make the switch to renewable energy technologies very soon, we're going to be living in a world that has been altered for the worse and there will be nothing we can do to change it. This all appears to be common sense to evrybody with the exception of politicians and oil companies; Go figure.
