1. Our First E-book is on the way!!

We are very excited to announce that our first e-book will be available this month! It provides in-depth information on a specific renewable energy topic. We will keep you in suspense about the e-book's title and topic for now, but I can tell you that it will definitely be worth waiting for!

You will be sent another Power Report soon with a date the e-book will be available.


2. A new wind turbine at Power-Talk.net – The Iskra AT5-1

Iskra Wind Turbines is a small wind turbine company located in the U.K. This engineer-owned company has previous experience in wind power generation, such as developing the industrial sized Carter Mk II 300 kW turbine.

They now offer the Iskra AT5-1 to the U.S market. Currently this is their only turbine available.


3. Question of the month.

Q: Why is aluminum not a suitable material for wind turbine blades?

A: The main problem with using aluminum for wind turbine blades is fatigue. The force of the wind, if strong enough, will bend the blades back, then they'll return to their normal position. Aluminum, when repeatedly bent back and forth will weaken and eventually crack and lead to failure. Aluminum does not posses the elastic properties that polypropylene or wood do.

It does have one positive trait however. It's lightweight has less inertia to overcome which means it can more easily capture energy in gusty winds. But this fact alone does not outweigh the fatigue issue.


Do you have a question about renewable energy or off-grid living? Comments or feedback? We would love to hear from you. You can use our contact form to easily send us your inquiry.


Until next time,
