This Why We Need Alternative Energy Sources

Posted by admin on April 20, 2013 in Renewable Energy with 3 Comments


The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician’s world-wide are drafting policies and are making agreements to make greater use of these energy sources.

The first problem is that the fossil fuels are depleting in a rapid rate and are harder to retrieve. The consequence is that we can be facing an energy crisis in the future is we are not careful today. The energy prices will sky rocket and not be available for many individuals or countries. To avoid this doom scenario we need to find alternatives and used them to their full potential. Luckily this is already happening.

The second problem is that the fossil fuels that are widely used today are harmful for the environment. In the early seventies and eighties there were people and even scientist who preach otherwise, but today the negative effects are showing. The earth is warming up and climates are changing. There are parts in the world were there be more rain and sunshine and others parts will be come dryer then they already are. Another negative effect is that the ozone layer is getting thinner which also leads to a warming up of the earth. These two effects compliment each other and make it even more crucial to make another step in a different direction. This step will lead us to the use of Renewable Energy.

Another problem lies in the development of small economies. Because the energy prices for crude oil are going through the roof, these countries suffer even more. Many of these countries need crude oil for their electricity and means of transportation. These high oil prices have their effect on almost everything. The monthly electricity costs for households increase among others like transport cost and prices for basic products. Hence, these high oil prices make it harder for these small countries to grow there economies.

The solution for the above problems can be resolved by renewable energy. Our beautiful planet gives us the opportunity to make proper us of sunlight, flowing water, strong winds, and hot springs and convert these into energy. These energy sources are abundant and free to use. We must be sure that we convert the energy the right way, without causing other problems that can again hurt our environment. Luckily the many efforts by individuals and companies show that this can be done.

    How efficient are fossil fuels compared to alternative energy sources?
    By alternative energy sources I mean things like solar, wind, nuclear, geothermal, hydroelectric, etc. I want to see how efficient they are, not really paying attention to how polluting they are.

    I recommend you watch the science channel and look for the TV show hosted by bill Nye

    You can’t make a meaningful comparison that way.
    A coal plant, for example, may have 30% thermal efficiency. The coal it burns, though, comes from plants that had only about a 2% efficiency in turning sunlight into biomass. A nuclear plant using the same steam technology as a coal-fired plant has about the same thermal efficiency, but involves far less fuel – indeed, some nuclear plants make more fuel than they use.
    Thin-film solar panels are only about 1/5 as efficient, area for area, as standard silicon solar panels, but cost about 1/10 as much. Either panel has far higher overall efficiency than a coal-fired plant, but involves manufacturing costs that makes their electricity more expensive if subsidiary costs (like adverse health effects) are neglected.
    Relative availability of energy is also an issue. Solar and wind aren’t always available. A hydroelectric dam becomes useless if the river feeding its reservoir dries up.
    The wiki article referenced discusses relative costs of electricity produced by various methods.
