What is Alternative Energy
By Dave Kettner
There is a lot of that we can harness if we only seek to research and develop the technologies needed to do so. We can get away from the fossil fuels and the old electrical grids by turning to alternatives to these sources.
One of these alternative resources is wind power. Wind turbines continue to be developed that are progressively more efficient and less costly. “Wind farms” have been springing up in many nations, and they have even become more strategically placed over time so that they are not jeopardizing birds as former wind turbines did.
Another alternative resource is the one that is most well known: solar energy. This involves the manufacturing of solar cells which gather and focus the given off directly by the sun, and translate it into electricity or, in some cases, hot water. As with wind energy, solar creates absolutely zero pollution.
Ocean wave is seen by governments and investors as having enormous generating potential. A generator in France has been in operation for many years now and is considered to be a great success, and the Irish and Scots are running experimental facilities.
Hydroelectric power has been with us for a while and where it is set up, it is a powerful generator of electricity and cleaner than a grid. However, there are certain limitations to the availability of the right places to set up a large dam. Many run-of-the-river, or small and localized, hydroelectric generators have been set up in recent times due to this limitation.
Geothermal is extremely abundant, since it lies directly beneath our feet, just a few miles below the earth's surface. This is produced by the
WattBusters Slashes Prices
<img border="0" src="http://www.wattbusters.com/images/announce.jpg" align="left" width="96" height="125" hspace="10" vspace="20">Good news people. We've cut the price of many products on our website. Due to volume purchasing, <a href="http://www.wattbusters.com"> WattBusters</a> can now offer the same great products at lower prices and pass the savings on to you. <br><br>
As products come to market, we are able to work with manufacturers to acquire
larger lots of new and current items. With an eye toward cutting energy usage and the resulting reduction of pollutants in the air and water, we're excited by the positive impact each item brings to the environment. Changing a light bulb seems like such a small thing but when you add up all the energy-saving light bulbs being installed all over the country, we're making BIG changes.
New Cold Cathode Dimmable and LED Bulbs

all of the people who have searched for an energy-saving replacement bulb to use in
dimmable chandelier fixtures, WattBusters finally has the ticket. We just acquired the <a href="http://www.wattbusters.com/store/customer/search.php?substring=cathode"> TCP cold cathode</a> line of light bulbs. The bulbs are excellent for dimming and rapid
on/off cycling applications and they use either 3 or 5 Watts. Light output is roughly equivalent to 15 - 30 Watt incandescent bulbs. <br><br>The FlameTip series is a sharp looking bulb that comes in medium or candelabra base and has clear, frosted or white coatings. The bulbs dim very smoothly and are a great energy-saver for any multi-light chandelier. The rated life is 25,000 hours so you pretty much install them and forget them.
heating of water through the actions of earth's fantastically hot molten core. The water turns to steam, which can be harnessed and used to drive turbine engines which in turn generate electricity. Great amounts of research and development should be put into geothermal tapping.
Waste gas energies, which are essentially methane, reverse the usual energy-pollution relationship by creating from waste that lies in the dumps and from some air pollutants. This gas is used in fuel cells and can be used in standard gasoline generators.
Ethanol is a gasoline substitute and is created from such things as wheat, sugarcane, grapes, strawberries, corn, and even wood chips and wood cellulose. There is controversy over this fuel with regards to its ever becoming truly economical or practical except in very localized areas, but technologies for its extraction and admixturing are continuously being refined.
Biodiesel is created out of the oils contained in plants. So far, the commercial stores of biodiesel have been created using soybean, rapeseed, and sunflower oils. At the time of this writing, biodiesel is typically produced by entrepreneurial minded individuals or those who want to experiment with alternative energy, but commercial interest from companies is on the rise. It burns much cleaner than oil-based diesel.
Atomic is created in atomic plants using the process of nuclear fission. This is extremely efficient and can generate huge amounts of power. There is concern from some people about what to do with the relatively small amount of waste product atomic gives off, since it is radioactive and takes hundreds of years to decay into harmlessness.
