Wind Energy Giant Vestas Has Grand Vision for the Future
Here’s the president of Vestas Americas, Chris Brown, speaking to a large audience at WINDPOWER 2016. An excerpt: Sustainability is the next chapter in human progress, and the key is making renewable technology economic.
Breakthrough in Wind Energy?
It’s a shame when total BS is represented as some sort of technology breakthrough. Here’s a development in wind power that couldn’t possibly work as advertised.
Wind and Solar Are Variable Resources, But What Does That Imply About the Need for Back-up Power?
Let me reiterate what I just wrote in a comment: The notion that incremental solar and wind plants require significant amounts of additional backup from fossil fuel plants is a myth. This is explained very nicely in the article linked above. …
News Flash: New Concepts in Renewable Energy Need To Offer Improvements Over What We Have Today
Part of my career involves looking at new ideas in clean energy, which enables (forces?) me to look at some really wild stuff that couldn’t possibly work. The inventor of this concept in wind energy called the other day to explain …
The PTC (Production Tax Credit) for Wind Energy
A reader comments on my post on the alarming report predicting the future of fossil fuels and renewable energy, “Regarding your comment about the cost of wind (which is as low $0.02 per kWh in some rare circumstances), sounds like time …
Breakthrough in Wind Energy?
A colleague in England, Gary Tulie, sent me this concept for extracting the energy from wind without a turbine. Here’s our conversation: Craig: Thanks for this, but aren’t you extremely skeptical? The wind blows charged particles apart from one another? …
Wind Power at Enormous Scale
2GreenEnergy Supporter Gary Tulie writes from his home in scenic Buckinghamshire, England (pictured): Hi Craig, I have wondered for a long time how big wind turbines might eventually get. This article indicates a possibility of reaching 50 MW per turbine. With …
Cheap Wind and its Value To Humankind
In the United States, there are now 50,000 wind turbines, generating 70 gigawatts (GW) of electricity, enough to power 19 million homes. The cost of wind-generated electricity is down 66% since 2009. It is now nearly 5% of American electricity, …
