I have a responsive template. I have read that HTML5 supports & encourages SVG (scalable vector graphic) for logo use.
Is that correct? I can insert my SVG of the logo into my images folder and be good to go?
No, that's not how it works.
HTML5 supports SVG and does encourage its use. But, it is for 'shapes' in your webpage, not the usage of SVG files directly!
Like, you can draw shapes in SVG format in HTML5 webpages. Take a look at this link: http://blog.romanliutikov.com/coding/svg-in-html5-introduction/
So, you can use SVG snippets in HTML5 to re-create your logo (depends on how complex it is) and render it as SVG.
Read up about it on W3: http://www.w3schools.com/html/html5_svg.asp
To give you an example, the following SVG code produces a background-gradient in some browsers.

Sorry to disagree with the previous replys, but -
In all browsers that are html5 aware, you can use an svg img, (yoursvg.svg) directly in the html5 img tag, or as a css background-image, or even place the svg code directly on the page, (in-line).
And if you are targeting only Safari or Firefox, you can include svg animations in your svg, and have the animation work even when inserted as a css background-image.
Use an IECC targeted at IE8 and below for the fallback image.
A lot depends on what you are planning to do with the svg, if you are targeting mobile and desktop devices then an svg with a IECC falback is the x-browser and future proof method. Also if you are planning on animating the svg or using css transform/transitions or animations then svg is also resolution independent, (no loss of quality on retina displays, such as iPod/Pad/phone the new Mac books, or Samsung's hi-def displays).
A lot depends on what devices you or your client wishes to target, or on any additional features for the site.
No one should think that using svg/html5/css3 are simply better than older methods just because they are newer, the use of these must be part of an overall site strategy, and currently that also means one must know how to provide fallbacks.
