Solar Power: Advantages and Disadvantages

There are many advantages of solar energy. Just consider the advantages of solar energy over that of oil:

Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days, etc., we can count on the sun being there the next day, ready to give us more energy and light. As long as we have the sun, we can have solar energy (and on the day that we no longer have the sun, you can believe that we will no longer have ourselves, either).

Oil, on the other hand, is not renewable. Once it is gone, it is gone. Yes, we may find another source to tap, but that source may run out, as well.

Solar cells are totally silent. They can extract energy from the sun without making a peep. Now imagine the noise that the giant machines used to drill for and pump oil make!

Solar energy is non-polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air.

Solar cells require very little maintenance (they have no moving parts that will need to be fixed), and they last a long time.

Although solar panels or solar lights, etc., may be expensive to buy at the onset, you can save money in the long run. After all, you do not have to pay for energy from the sun. On the other hand, all of us are aware of the rising cost of oil.

Solar powered lights and other solar powered products are also very easy to install. You do not even need to worry about wires.

As you can see, there are many advantages of solar energy. The advantages of solar energy range from benefiting your pocketbook to benefiting the environment. There are actually only a few features of solar energy that can be considered disadvantages.

Here are the disadvantages of solar energy:

Solar cells/panels, etc. can be very expensive.

Solar power cannot be created at night.

As you can see the advantages of solar energy create a much longer list that the disadvantages, and the disadvantages are things that can be improved as technology improves.

Star Trek - A History of the Game

Of all hit comic books, television shows and movies there is none more suited for adaptation as a video game than the Star Trek series. With its well developed characters, a very realistic sci-fi setting and millions and billions of starry eyed fans it's no wonder that copies just seem to disappear of the shelves the second any Start Trek games hits the market. The first Star Trek Episode was aired in the year 1966 and stayed right on top of the charts for more than three years. By the time the last episode of the original Star Trek was aired in 1969, this futuristic concept screamed of being developed for a more interactive medium - namely video games, where fans could participate directly in the revolution.

The first Star Trek Game was created by an unknown team of coders in 1975. For those who were fond of combat aspect of Star Trek, the game proved to be really addictive and was surprisingly quite advanced for the time it was made. The basic plot of game was short and to the point. For reasons not mention the peace treaty between the Klingon Empire and the Federation has collapsed, and you as the commander of the USS Enterprise, have to use all your resources, to destroy the Klingon Armada, which they have sent to into the Federation territory. It hardly needs to be mentioned that the interface was wholly text based you had to type in your instructions and the results of your decisions were typed back to you.

Once personal computers became commonplace, a number of games were Star Trek based games were created. But gamers got their first real dose of the Star Trek Series with the release of Star Trek: 25th Anniversary. Developed by Interplay the game was a graphical adventure that set really high standards for all future Star Trek games. Like each Star Trek Episode is a self contained drama, the game too had a number of mini-missions, which the player was supposed to complete. After the end of each mission the player got an evaluation report that analyzed his overall performance.

Another great game was Star Trek: Klingon, which was hailed by the critics as the "ultimate interactive adventure". In the game the player takes up the Persona of Pok, a young Klingonian who has to avenge the death of his father. Its one of the most interesting Star Trek games you will ever come across.

Another Star Trek Game which followed a similar plot structure was Star Trek: Borg. In this game you play the role of a Starfleet recruit, who is sent back in time by Q, to save the life of his father who was killed by Borg. A fast passed adventure game, Star Trek: Borg is all about making split second decisions.

The other interesting Star Trek titles that you should definitely play are Star Trek: Armada and Star Trek: Voyager - Elite Force. Both of them have been created by Raven Software, so you can be sure that you won't be disappointed.
