From Guest Blogger Jim Stack: Hawaii — Land of Oil or Renewables
| December 1, 2011 | Posted by jstack6 under Renewables - Science |
Hawaii has been known as a land of paradise. They have a great climate and can grow anything anyplace. But did you know Hawaii runs most of paradise on oil-generated electricity? Of course, all of the oil is imported too.
Recently becuase of fast growing prices they started looking at renewable energy in Hawaii. They found they have great solar, wind, hydro wave and currents and even geothermal energy. They are now just starting to develop these great renewable energy sources.
In Hawaii they have have many small islands and micro grids that are not connected. This makes it difficult to combine all the great renewable energy sources they have into an efficient grid. Read More

Infographic – History of Renewable Energy InfoGraphic
| October 28, 2011 | Posted by Craig Shields under Renewables - Science |
We at 2GreenEnergy are on a quest to introduce the basic concepts of renewable energy to newcomers to the field, and, to that end, we’ve begun to create a series of “infographics,” providing a few essential concepts at a glance. Here’s a one-pager we did, depicting a brief history of each of five main types of clean energy. We’re hoping that this puts a few central concepts into perspective for folks.

EV World Editor Bill Moore Speaks with Craig Shields on Renewable Energy
| October 21, 2011 | Posted by Craig Shields under Renewables - Science |
Here’s a grainy but clearly audible video in which EVWorld editor Bill Moore interviews me over a Skype session on my book, Renewable Energy — Facts and Fantasies. He’s a good guy, and asked some terrific questions.

Energy Videos for Newcomers
| October 13, 2011 | Posted by Craig Shields under Renewables - Science |
I’ve been preparing to make a few videos for newcomers to the subject of clean energy that answer basic questions on renewable energy, fossil fuels, nuclear energy, and the energy-related challenges we face. I’ll be recording a series of short talks, aided by graphics, that point out that all our energy sources go back to the Big Bang, and come forward through time to us as follows:
Solar power is nuclear, of course, as all that hydrogen that became our sun billions of years ago undergoes fusion and emits enormous amounts of energy. That which we accumulated over hundreds of millions of years as fossil fuels (ancient biomass) we extract and burn as oil, coal, and natural gas. That which we receive right now, or in the very recent past, we have the potential to harvest as renewables: photovoltaics, concentrated solar power, wind, new biomass, run-of-river hydro, ocean current, and wave.

Talking Renewable Energy on “Getting Your Money’s Worth”
| October 12, 2011 | Posted by Craig Shields under Renewables - Science |
Many years ago I donated 90% or so of my neckties to charity as I almost never wear one anymore. But I’m glad I didn’t get rid of them all, as here I had a rare opportunity a couple of weeks ago when I was in New York City and taped an episode of “Getting Your Money’s Worth,” in which I discuss renewable energy with show host Judith West. (The video displays better on Internet Explorer than other browsers.)
It was actually quite a rocket ride, where Judith asked about solar, wind, fossil fuels, electric transportation, and a range of other subjects concerning the politics of clean energy.

What College Students Interested in Renewable Energy Should Study
| October 4, 2011 | Posted by Craig Shields under Renewables - Science |
A fine young man, Rudy Chavarilla, called me this morning from American Amp and interviewed me for about half an hour. We recorded a show on the subject: What college should students do vis-à-vis sustainability that will be distributed to over 300 college radio stations.
This whole process makes me feel good all over. I honestly love to speak with college students, though when I do, I have a habit of throwing in the kind of cliches that embarrass the bejeepers out of my kids. “Enjoy these brief moments. These are the best years of your life. Read great books. Learn to live an examined life. Kiss a few good-looking members of the opposite sex.” Seriously, my kids want to barf when they hear me I carry on like this. So I thought the better of going down that road, and answered the interviewer’s questions without any of this sort of editorializing. Read More

How “Green” Is Your Electricity?
| October 3, 2011 | Posted by Craig Shields under Renewables - Science |
Here’s last month’s webinar, in which I interview Jim Holbery, Ph.D., CEO and founder of GridMobility. It’s a 60-minute discussion on how electricity is generated, and how consumers can stipulate their preference for renewable energy.
This, of course, is a non-trivial task, as “green” and “brown” electrons move around our grid with no discrimination at all. So how did Jim’s team pull this off? I hope you’ll check it out. Read More

Global Climate Change Basics
| September 28, 2011 | Posted by Craig Shields under Renewables - Science |
Don’t we all feel our hearts warmed when we realize that a friend “has our back?” Frankly, I don’t particularly feel that my back needs protecting, but I did write recently:
A radio talk-show host reviewed my book the other day with an eye toward having me on his show. He wrote back just now: … I found it to be interesting, though I should tell you I’m one of the people who don’t believe in global warming….I also believe we have enough fossil fuels to last for hundreds of years if we were allowed to get it … I think it (having you on the show) would make for an interesting segment.
A friend wrote back:
Sounds like a potential ambush to me. I strongly suggest you spend some time memorizing these talking points about Global Climate Change before going on the show.
I’m grateful; I feel very well taken care of. I urge everyone who happens to be interested in the subject of global climate change to check out the link my buddy provided above; it is, IMO the most up-to-the-minute treatment on the subject.
