Introduction To Renewable Energy Sources
Author: Link Canon
As the worlds energy crisis becomes more and more obvious, the importance of reducing society's dependence on non-renewable energy sources like fossil fuels is more and more urgent. Non-renewable energy sources are on the way out. Renewable energy sources, such as a home wind turbine, can put out energy cleanly and without using up rapidly depleting sources. There are three types of renewable sources to look out for: solar, hydro, and the most promising, wind.
Hydro energy is currently the most popular renewable energy source. In the future however, this is likely to change. Although hydro energy is clean and efficient, it is extremely detrimental to local environment and ecosystems. Although hydro energy is being developed to operate cars and appliances.
By far the best and most promising solution is wind energy. For around 0 dollars, anyone can set up a small home wind turbine and begin harnessing the wind to power their home. wind is completely clean and efficient. Before wind was too expensive to employ at the consumer level but with recent technological advancements, virtually anyone can begin using it. There is a low start up cost and very little maintenance. The future is here when it comes to wind power.

I'm currently an environmental science student and after studying the state of the world's resources, I'm doing my best to get people excited about alternate energy. If you're interested in more information about wind power or how to build your own home wind turbine, visit my home wind turbine website.
good question, and I appreciate your concerns, here are some possible things to consider. Most water generating is done by building a dam on a river, diverting the flow of the river into a lake, and then using the water of the lake to turn a generator. It is a very efficient means of producing electricity. However, when was the last time you heard of a large dam being built on a river? That’s right, the enviro-greenies have stopped every proposed dam project in the last 20 years, and the liberal courts have supported that situation, so go talk to the Sierra Club if you want more hydro-electric power produced.
You mention the sun, and of course it is the primary provider of energy on this planet, however, the technology to produce electricity directly from the sun while real, is not particularly efficient. consider this, for a medium sized airport in Nevada, where the ratio of sunny skies is the best in the world for solar production, they would need almost 700 acres of photo-voltaic cells to power their needs, with the associated lead-acid batteries to store the power for the night time operations.
Wind energy conversion to electricity is real, and is well documented, however, most people do not want them in their neighborhood-why? They are an eyesore, and they are noisy. And, what a surprise, the liberal greenie’s don’t like their possible adverse effects on plants and animals….
By biomass, I assume, you are considering either converting the biomass to alcohol, or burning the biomass to produce heat to produce electricity…I am not too clear on this one, so please explain your intent more…
Here is the problem: the world has plenty of fossil fuel, in oil stocks, shale oil, coal and natural gas. The problem is that it is not distributed fairly within the world as a whole. In the US and Canada, we are blessed with a large supply of coal… It can and should be utilized to the full capability of the material. In addition, nuclear power generation is safe, cheap and virtually endless in availability…The Enviro-greenie-liberals do not want it used because they want to stop all human development, they believe there are too many people and we need to do away with large numbers of them in order to preserve the earth. That is their religion, and that is their agenda, to oppose any use of natural resources that will aid the human race in survival…just my opinion, read and study the problems yourself, do not take my word for it, continue to ask questions and seek the truth yourself-good luck.
Renewable energy vs non renewable energy…
How can we start using renewable energy resources (water, sun, wind, biomass, etc…) for energy instead of fossil fuels and other nonrenewable energy resources? How can we avoid to continue using these resources that are bad for the earth???
The difference between renewable and inexhaustible is the time scale that you’re operating on. Ex: As far as humans are concerned the sun is an inexhaustible energy source. But the sun will eventually burn out. So if you’re willing to wait long enough NO energy sources are renewable or inexhaustible. Granted that’s an extreme example. But it demonstrates how the presumed time scale is important. Here’s another example: “biodegradable”. Fine… on what time scale? Nuclear reactor sludge is biodegradable if you wait long enough.
Renewable vs innexaustable?
whats the difference ik what non renewable is but wats the difference between renewable and innexaustable and if u can what kind is electrical energy
I’m in a lesson help me with my work please?!?!?
1) Find out if these energy resources are renewable or non renewable and make a table in your book:
Coal, Wave Power, Hydroelectric, Solar Power, Crude Oil, Biomass, Wave Power, Natural Gas.
2) Find out how energy gets into coal and oil. Draw a cartoon (in your book or in a suitable program) to show how this happens.
3) Find out what energy changes happen in a coal power station- turn this into an energy transfer diagram.
Task 2 – Fossil fuels vs renewable energy resources.
Create a table showing the advantages and disadvantages of renewable energy resources and non renewable energy resources.
Think about living near a power station or wind farm- how would you feel.
There should be loads of suitable sites online – or try the library. I’d say try online first – type these subjects into the Search Bar – you’ll find loads of helpful info there. Besides, if we helped you with your schoolwork, you’d never learn to do these things for yourself.
There is a table from the Dept. of Energy that compares various vendors and their costs. See:
http://www.eere.energy.gov/greenpower/markets/certificates.shtml?page=1
In effect, you are donating money to fund alternative energy sources (wind, solar, hydro, biogas) that subsequently feed into the nat’l power grid.
Since you are donating money, you might as well get a charitable deducation on your income taxes. The nativeenergy.com site won’t give a definitive answer on this question, but suggests you can do it.
So go with a group which is a charitable non-profit organization that clearly states donations are tax deductible. Look at your yearly electricity bills, multiply kilowatt hours by 2 cents and donate that much.
Unlike the carbon offset credits that are often nebulous and sometimes outright fraudulent, renewable energy credits (RECs) trace back to definite generating capacity that can be (and usually are) audited to make sure they are above board. (The US gov’t buys RECs, so any egregious fraud tends to get uncovered quickly.)
I think you are taking the right approach to renewable energy, and these projects will stand the test of time regardless of how the global warming issue pans out.
Despite all the bashing of the US, the graph at:
http://www.eea.europa.eu/pressroom/newsreleases/GHG2006-en
shows how the EU-25 don’t come close to meeting their Kyoto promises.
The non-Kyoto country, the US, in 2006 DECREASED CO2 emissions in by 1.4%.
I guess that signing Kyoto and then reneging somehow makes countries feel noble and good about themselves. But buying RECs that actually do something doesn’t count.
What Are Some Pros and Cons of Different Organizations that Assist With Purchasing Renewable Energy Credits?
There are two organizations that I have been considering: 1) LiveNeutral (www.liveneutral.org); and 2) Native Energy (www.nativeenergy.com).
Some issues that I am considering are: 1) non-profit vs. for-profit; 2) credits purchased from the Chicago Climate Exchange (CCX) vs. credits created from renewable energy sources; 3) “imaginary” market vs. real-world projects; and 4) managed by educational institution vs. managed by Native American organization. Please feel free to suggest additional criteria.
Also, if there is another organization that you think I should consider, please let me know, and please provide your reasoning for the suggestion.
Thanks!
Is it immoral to eat more than you need?
In the spirit of our (Americans’) new found realization that constant overconsumption of resources is, um, ruining the earth, how to do you feel about our shameless overconsumption of food?
The debate over renewable vs. non-renewable resources notwithstanding, should the argument against overconsumption extend to food?
Fun question, huh?
GLUTTONY!!! (I’m such a bad fall-away Christian) I totally forgot about the seven sins. So I guess that says it all, huh -
Yeah, fun question
Yes, I think it’s immoral. We know it’s bad for our bodies, and we know that there are a LOT of people in the world that don’t have nearly enough to eat…yet we still overeat. I think you could sum it up by saying overeating is giving into temptations and also a failure to do something that would help other people (and yourself) … and with anything else that would be classified as immoral.
