Writing Articles - but want to avoid duplicate penalty

[staffjam]

I've been writing a batch of alternative energy articles and using online sources to obtain the data.
The articles are different in "almost" every way, as there are a few groupings of words that couldn't really be substituted.
I would say a maximum of 5% could be similar to the source articles.
Is this something that would be punished by google, or is there a certain amount of leeway given? as hardly any article or piece of work out there can be considered truly original.

Thanks for any advice

I will suggest to write 100% content in your own words. You may get info online but when it comes to writing the article, you should then write everything from yourself. Google hate duplicate content and I will say to not take the risk of having any percentage of duplicate content in your articles.

And you will face the happiness with unique content

i would not worry about a few strings of borrowed identical text especially if it is only 5% sprinkled around your own original content

No problem at all.... Writing a 100% unqiue article is next to impossible, unless its one random sentance.

20%, maybe 30% is okay.

Anyway, this is all a mute point.
As much as we all struggle to write a nice content article and keep it fresh, as soon as we make a few copies of it, the article becomes less valuable and even worse, if the article is any good, you just know that a thousand other people are going to copy n paste it into their own blogs and sites.

You can only monitor this by using a copywriting tool check and ask them to remove it.
