According to Science Daily, the Costs of Solar and Wind Continue to Plummet, and Renewable Energy Is Rapidly Replacing Fossil Fuels

Peter Buck writes: I found this article interesting–along the lines you propose in “Bullish” (on Renewable Energy) i.e., that solar and wind power will be the cheapest forms of energy in the future.

Thanks very much, Peter. Yes, this really is happening, and for the exact reasons I lay out in the book; it’s gratifying to see them printed in such an august publication. (more…)

Emcycle Likely To Become a Reality

craigshieldsPosted on February 10, 2015 Posted in Electric Vehicles

I’m happy to note that the Emcycle (pictured below), an electric bicycle whose design I think is really cool, will probably be going into production soon in Europe. Longtime 2GreenEnergy readers know that I think the world of Emcycle CEO Michael Scholey, that I featured him in a series of video interviews, and that I’ve suggested to many hundreds of thousands of visitors to our website that I think Emcycle is a potentially attractive cleantech business investment opportunity.

It’s good news that Europe will be the focus of this innovative firm’s activities; I’ve always thought that the big cities in the EU are the very best targets for the product. They’re both frustrating and terrifying to drive through and park in, and they get a lot of rain; if you don’t have precipitation, you’ve lost a great deal of the value of this product. (more…)

Keeping Track of the Earth’s Climate

craigshieldsPosted on February 9, 2015 Posted in Climate Change

Today is the 145^th anniversary of the establishment of the U.S. National Weather Service. Thus, when we say, “2014 was the hottest year on record,” what we really mean is that it was the hottest year in the last century or so.

It’s amazing how many of our human inventions came along fairly recently. (more…)

India: Thinking Big on Solar Energy

craigshieldsPosted on February 9, 2015 Posted in Photovoltaics

Here’s a fellow in India building a 10 GW solar farm. That’s an impressive number, but by my quick calcs, that’s almost 200 square miles at 20% efficiency. That’s a lot of real estate.

Of course, India is comprised of 1.15 million square miles, and 10 GW offsets a ton of fossil fuel. In addition, India loves solar generally. The Ministry of New and Renewable Energy (MNRE) for India has identified solar off-grid as one of the key aspects of rural electrification.

We Need To Make Tough Choices In Some of Life’s Arenas—And Energy Policy Is One of Them

craigshieldsPosted on February 9, 2015 Posted in Renewables - Politics

Fifty-one years ago this evening, the Beatles appeared on the Ed Sullivan Show and attracted a television viewing audience (73 million) that stood as a record for some time. I was a little boy taking piano lessons, and I recall that my teacher, Ms. Young, was not at all pleased when she saw me later in the week; she asked me if I had tuned in and I answered in the affirmative. She scowled: “Do you like this garbage???” (more…)

Coal Won’t Go Gentle Into That Good Night

craigshieldsPosted on February 8, 2015 Posted in Fossil Fuels

The ad below is a call to action focused on Australian coal miners, but it illustrates a larger point: there are interest groups on all sides of every issue—some helpful, others harmful. Yet getting rid of destructive practices isn’t as easy as one might hope. (more…)

Clean Energy’s Role in the Advancement of Our Civilization

craigshieldsPosted on February 8, 2015 Posted in Renewables - Politics

It’s the birthday of Jules Verne (pictured), author of fantasy books of the mid-19th Century. According to the Writer’s Almanac:

Verne described inventions that were similar to modern airplanes and automobiles, and tall skyscrapers where people use electricity to listen to the radio and send faxes, and yet he wrote his stories by candlelight.

Hollywood is littered with screenplays that project the world of the future, most of which are deeply dystopian, normally visions of a post-apocalyptic period where what’s left of humankind is locked in some sort of tooth-and-nail struggle for precious resources. (more…)

From Guest Blogger Martin William: The Latest Trends in Home/Kitchen Appliances

craigshieldsPosted on February 8, 2015 Posted in Efficiency

The kitchen is one of the most important parts in a house. It is where the family gathers the most aside from the living room. Over the years, the appliances that fill a kitchen have transformed, following the latest trends and new technologies. This year, the trends in home and kitchen appliances are focusing more on simple designs and connectivity.

A Smart Home

Ever since the Nest thermostat became very popular, the revolution towards a smarter home was kicked off. Smart TVs can now accept voice command, browse the internet and even record the shows you want to watch for you based on your habit and other inputs. (more…)

Analyzing Claims Regarding "Breakthroughs in Physics"

craigshieldsPosted on February 7, 2015 Posted in Renewables - Science

At the rate of approximately one per month, I receive emails from people who claim to represent breakthroughs in physics that are called “over unity” or “perpetual motion,” where the purported efficiency of the process is greater than 100%, meaning that they put out more power than they consume. This concept, of course, violates the laws of physics, specifically the first and second laws of thermodynamics. Yet the fact that what the person is describing is theoretically impossible normally does not deter him in the slightest. (more…)

The Lighter Side of Climate Change Denial

craigshieldsPosted on February 7, 2015 Posted in Climate Change

My biggest problem with 2015 so far is that it’s happening in the absence of Steven Colbert, at least in the form of the “Colbert Report.” I had forgotten how fabulous this whole enterprise was until I came upon this piece on climate change denial.

I saw this when it first aired just after the U.S. midterm elections last November, but I laughed until tears were streaming down my face when I watched it again just now. Enjoy.
