It came as no surprise when the promoter of this small wind turbine was upset by my post the other day “Video on Small Wind,” in which I pointed out that his claims were preposterous. I began, “Will the wind …

Video on Small Wind
Will the wind turbine here generate electricity? Yes. Will it do so cost-effectively? Not in a million years. • Vertical axis machines are intrinsically left efficient than their horizontal axis counterparts. • This device invokes drag rather than lift mechanics.
Airborne Wind
The developments in renewable energy over the last decade can be summed up as follows: the winners have won and the losers have lost. The plummeting costs of energy from solar and wind have put extreme pressure on things like …
Details Released on 14-MW Offshore Wind Turbine
The cost-benefit analyses of offshore wind projects differ from those of their on-shore cousins, in that the installation of each turbine is a far bigger component of the total cost. For that reason, bigger is always better, and this is …
Notes of Healthy Living and Wind Power
I’m trying to lead a healthier life, getting more exercise, eliminating dairy, and cutting back on drinking. I put a shot of Lysol in my coffee just now as a replacement for milk, and this evening it will be a …

Sketchy Idea in Renewable Energy
Think about this. You’re driving along an unlit road, and your car passes one of these lamps, creating the gentlest of breezes that creates a tiny, almost imperceptible bit of light, shining on the road–behind you. Does that seem practical?

Renewable Energy in Scotland
The meme here is a reminder that the bagpipe is one of the best tools for social distancing. Kidding aside, as a result of its heavy commitment to renewable energy, wind in particular, Scotland is generating twice as much power …
The Iberian Renewables Boom: A Tale of Two Continents
As reported by GreenTech Media, Spain and Portugal are on a tear to build wind farms, in a concerted effort to meet their 2050 objective of carbon-neutrality. Spanish oil giant Repsol is using the metric of carbon intensity to gauge …

Harmony Vertical Axis Wind Turbine
Like so many presentations on cleantech products and services, this video on the Harmony VAWT starts with some important points about environmental stewardship. No one doubts that supplying energy for use in residential, commercial, and industrial settings is one hell …
Wind Energy Concept
A reader asks, “What do you think of this idea?” Let’s do some math, and call the length of the blades x. the swept area of this device is 4πx2. The radius of one big turbine, assuming the blade tips …
