Renewable Energy

Here is where I start showing my age back in the 70s we call it alternate energy or AR.

Now days I have to get use to calling it RE.

Now extracting power from natural sources solar, wind, micro hydro, and biomass. Can offer many interesting engineering challenges.

But you have to remember that there is no such thing as a free lunch.

But if you do your homework you can find ways to cut your energy bills with a reasonable pay back time.
