All of us Americans who use Google (pretty much everyone) know that today is the birthday of Frederick Douglass, one of the most influential forces for social reform in U.S. history. He’s probably best known today for his summary of how social change actually takes place:
If there is no struggle, there is no progress.
Power concedes nothing without a demand. It never did and it never will. (more…)
Here’s an article that points to exactly where we’re going as a civilization, or at least, where we need to go. The author’s “Future Earth” program is one that considers Earth science from a holistic perspective. From the article: (more…)
We often forget that CO2 isn’t the only greenhouse gas, and that fossil fuel consumption is not the only contributor to global warming. In fact, even if we’re completely successful in making the migration to renewable energy, we still have serious issues associated with the raising of cows and other ruminants, animals that have contributed 14% of the total GHGs to our atmosphere since (more…)
In this week’s edition of “Green Auto Digest,” my colleague Jon LeSage covers the “nexus” between electric and autonomous vehicles. That such a phenomenon actually exists is certainly good news, as it will accelerate the rate at which we can slowly but steadily diminish the importance of oil as a commodity, while disempowering one of the most malevolent forces on Earth.
Wow. First the “energy-water nexus” and now this. If 2GreenEnergy could experience the same spike in popularity as the word “nexus” has enjoyed recently, I’d be a happy man.
Yesterday I made a flippant and slapdash remark to a reader who questions the role of government support for renewable energy, where he was commenting on my piece about “Big Wind.” In my apology, I wrote:
I should have taken the time to express myself better. Here’s an attempt in that direction, using the following bullet points: (more…)
They say the future of our planet becomes relevant when we choose to invest in the next generation. In theory, decorating a home is easy. The right furniture and a perfect color blend should be enough to satisfy our need for a pretty space. However, when you’re decorating a space for your child, you’re forced to think about more than just design. Safety should also be a priority. When decorating their room, find a way to merge beautiful furniture with practical elements. Create a greener environment that’s appealing and comfortable, but also practical and safe. Here are some guidelines to help you out. (more…)
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 blades 200 metres long for a sweep of around 420 metres diameter and the blade tips traveling 1320 metres or 0.8 miles with every rotation.
Yes, I know you’re interested in this; one of the key contributions you made to “Bullish on Renewable Energy” covered this section. This article is truly amazing.
Gary then cautions: Don’t expect them on the market next week! My guess is modest scale proof of concept by around 2020, commercial applications at 10 to 20 MW by 2030, with larger machines maybe by 2040.
As I wrote yesterday, Obama is not checking out of here without making some extremely important reforms before he goes, and he seems to be picking up the pace as the time for his departure from office nears. Here he’s going after Citizens United, the US Supreme Court decision that grants corporations the right to spend as much money as they like to influence our elections and eviscerate our democracy.

In the modern world, scarcity of resources has made human beings adopt recycling techniques to avoid wastage of what is already scarce. By so doing usage of raw materials is reduced and prevent pollution of the environment hence making planet earth habitable for both living and non-living. There are several ways of managing waste such as: (more…)
Frank from Florida writes: How can a pro-nuke person honestly say that he or she is “concerned for our descendants and all species around us?” Don’t they know that after a nuclear accident it takes generations for living things to come back and thrive? (more…)
