We know that the Earth is experiencing record high temperatures, and that these data points are not isolated, but are part of long-term warming trends that derive from the buildup of greenhouse gasses in our atmosphere, largely due to our …
What Should We Be Doing as Temperatures Rise and Earth Becomes Less Inhabitable? Read More »
If you can be convinced that anything about these people’s claims is true, by all means, jump in with both feet. One such claim is that they generate some energy at wind speeds that are lower than those that activate …
After a second catastrophic failure, Agile Wind Power is removing its giant VAWT from the Grevenbroich test site. From this: The dismantlement follows the second failure of the test turbine (see photo). The Swiss company has been developing the mammoth giromill …
Massive Vertical Axis Wind Turbine (“VAWT”) Coming Down Read More »
Something about the picture here looks amiss, though it may be hard to put your finger on. Here’s the problem: the microscopically small amount of power that comes from small wind. Let’s say that the turbines shown here are 10′ …
A Wind Turbine on the Roof of Your House: What’s Wrong with this Picture? Read More »
Here’s another appeal to potential investors in this wind energy concept. The problem: The economics of small wind and small solar are completely different. Depending on where you live, putting solar on your roof makes sense. Putting this on your …
Here’s a short video describing how wind farms are built. Its producer says that renewable energy is required because “we’re running out of fossil fuels.” Completely wrong. There is so much coal in Wyoming, for instance, that hikers have to …
Here’s a good example of what I’ve been writing about since the launch of 2GreenEnergy.com in 2009: the rich economic value that lies in the transition to renewable energy. I hope readers will check out this report from the Pew …
Wind Energy Boosts Rural Economies in Central U.S. Read More »
Here’s an interesting video that compares small wind (<50 KW) with solar for the typical homeowner. The fellow concludes that small wind “isn’t there yet,” though there are some promising potential solutions coming onto the market soon; he actually predicts …
Here’s a concept for a new design in wind turbines. Contrary to what readers may have come to expect when they read that first sentence, this appears to make sense. The idea is based on the fact that, although today’s …
These people claim to have a workable solution in small wind, on the basis that its unique design gets around the problems that the industry has traditionally encountered. The main challenge in small wind, and the reason that the entire …
