Why is it that scientists generally are quiet and demure, and so seldom even mention the field of politics?  Perhaps it’s the very difference between fact and opinion, and scientists’ preference to the former over the latter.  In any case, Michael Mann is decidedly unafraid to make political statements in the name of climate science.  Here is an interview in which he chops up Virginia gubernatorial candidate Ken Cuccinelli, whom he calls out for the politician’s ties to the fossil fuel industry and the fabulously anti-science position that those ties have engendered.  Enjoy.

Many young people today believe their grandparents are some of the reason to blame for global warming and the resulting climate changes.

While humans have a huge impact on the environment, pointing fingers doesn’t help bring people to the green ‘side’.

Senior citizens aren’t as opposed to green living as some may think. The disposable age came after most of our grandparents were already living a semi-green lifestyle. Don’t think so? (more…)

Most people know what solar power is. But there’s still plenty that we don’t know about the science. Some of the facts and the myths about solar energy get mixed up, which is why we’re going to share 5 definite facts to get excited about…..

1. Solar Panels still work in cold and snowy environments.

They are obviously very effective in sunny parts of the world but you might be surprised to learn they still produce a great amount of energy in the snow. The panels are unaffected by the cold and take in the reflected photons from a reflective, snowy landscape. (more…)

Pictured here is a proof copy of my third book, Renewable Energy – Following the Money.  It’s in the final stages of proofreading, a considerable task.  I really hate to have typos in my stuff, but it’s not easy to find them all — especially for me.  I find errors in books that have been out for 10 years and sold millions of copies, but I have real difficulty in finding them in my own writing.

Obviously, I’ll notify readers when this one’s available on Amazon — should be just a few weeks.

I was on my way to the beach yesterday when I happened to notice that the group environmentalist Bill McKibben runs, 350.Org, had set up a whole bunch of tents at the nearby park and were busy making presentations on fossil fuel divestment and passing out DVDs on climate change. I spoke with one of their representative and was immediately impressed with his knowledge on the subject and level of commitment to changing what I referred to earlier today as our “stupid and selfish energy policy.” Keep up the good work.

Here’s an article that I urge our readers to check out on the apparent slow-down of global warming, a phenomenon predicted by our current climate models but not perfectly understood at this time.  Obviously, the climate change deniers are going to have a field day with this, though, of course, they’ll be missing the point, as they are wont to do.

I find it interesting that the scientists involved are so excited by the challenge. The closing line of the piece expresses a child’s wide-eyed wonder and exuberance about setting forth to find the answers.  “This is really exciting. We have got a problem to solve. We have things we don’t understand perfectly, and as a scientist, that’s really why I do what I do. I speak for all of us who are here.” (more…)

A reader asked for my comments on the following:

I have just been reading about the various ways CO2 is captured from power plants and then transported and stored — underground and underwater.  I don’t get it…we applaud companies for reducing their carbon emissions to solve one problem only to create another by having to find a place to store it, which is surely just as bad as emitting CO2 into the atmosphere in the first place.

Your comment? (more…)

Imagine every application that requires lighting in your commercial facility. Can’t wrap your head around it? Needless to say, lighting can be a huge percentage of your annual energy costs. Energy efficient lighting like LED wall packs or LED bollard lights  can make a significant difference in your energy bill.

Surprisingly, 22% of America’s facilities have never undergone any type of lighting upgrade, or it has been more than 10 years since work has been done, according to a survey in the April 2013 issue of Today’s Facility Manager.That means 1.1 million facilities are wasting energy—and wasting money.

What’s the real imperative of the migration to renewable energy and cutting back our consumption of fossil fuels via efficiency and conservation?  Might you say: Climate change?

We’ll, that certainly one good answer.  Of course, there are half a dozen others:  dealing with peak oil, health issues, ocean acidification, the loss of biodiversity, human hostility, etc.  When I’m interviewed on the subject and I encounter climate change deniers, I’m quick to change the subject.  As I often say, “If you don’t believe in climate change, that’s fine, just pick another good reason to curb our addiction to fossil fuels; most of them have nothing to do with this dreaded subject whatsoever.”

But having said all this, the build-up of greenhouse gases, which will eventually culminate in the melting of the arctic and the release of the methane beneath it, carries with it a fairly hefty price tag in terms of climate change per se, (more…)

Here’s a conversation I just had with a reader – one that I have in various forms at the rate of several per month.

Reader: Have you seen this yet? That’s why we need to get EVs in everyone’s hands. No mention of cost. (more…)
