Renewable Energy World’s Steve Leone published an article today on solar and its attempts to go mainstream, in which he mentions a great number of developments that will ultimately make solar far more appealing to consumers than it is currently. Some of these notions include transparent PV on windows, as well as PV roof shingles and other forms of building-integrated solar.

It was good to see he noted the role of electric transportation in the equation. I.e., there is clearly a growing number of people who want to control the source of electricity that charges their cars – and what better way to do that than to install that source on their roofs?

If we still have a civilization here in 2050, we will have “gotten there.” The questions are how much damage we will have done, and who’s going to get rich in the process.

At the conclusion of the last moonwalk that took place on this date in 1972, the astronauts unveiled a plaque, which read: “Here man completed his first explorations of the Moon, December 1972. May the spirit of peace in which we came be reflected in the lives of all mankind.”

That’s beautiful writing, and causes one to wonder how it’s possible that war is such an omnipresent reality here on Earth. Maybe it’s that we seemed so divorced from its horrors; it’s something that just rolls along, with skirmishes that are hardly newsworthy, taking place in some foreign land, affecting people we don’t know. Thus we “support our troops,” meaning (to most people) we “support the war effort.”

At a certain point, perhaps people will simply change their minds, and tell their leaders, “No, I don’t support this – even a little bit.  Make this stop, or start looking for a new career.” Until then, war, supremely profitable, will remain our paradigm for settling differences.

Very few people traipsing around this planet know more about energy efficiency than John Robbins. As he puts it: “Energy education for homeowners is my arena. I’ve thought, taught and written about it for a long time.” (Coming up on 30 years, to be exact.)

Efficiency and renewables are blood brothers; advocates of clean energy who aren’t pushing efficiency are completely missing the boat. And the fact that there is relatively little discussion of efficiency here is a sad truth that I’d like to rectify with great speed and force – which is why I’m encouraging John to put up more guest-blog posts soon.

I’m delighted that Ben Thorp has become friendly with us here at 2GreenEnergy. Here’s a guy who’s forgotten more about biomass than 99% of professionals in this arena know, and who frequently sends me scholarly papers he’s penned on the subject, in a patient and thoughtful effort to bring me up to speed. Here’s one of his recent publications, An Efficient and Sustainable Use of Biomass for Heat and Power.  Hope you enjoy.

[youtube http://www.youtube.com/watch?v=m-9nHzXswwk]I spent yesterday afternoon in the local television studio, shooting a series of videos for a variety of different purposes. I thought I’d send you this short (under one minute) piece that explains the premise of my next book, whose title I later revised to “Is Renewable Really Doable?” which will be available next month. Thanks to 2GreenEnergy co-founder George Alger for his work here; I think these are some cool video effects.

Fast trucking the development of clean energy in Africa has been a major challenge for which African states have to render political and governance support, one of the fundamental strategy is intergovernmental organizations and programmes of Africa’s group of nations. There are intergovernmental institutions and programmes for clean energy governance in Africa. The African Union (AU) is the principal organization of African states. It includes 53 African member States. (more…)

My great thanks to Seth Leitman, aka the Green Living Guy, for his article on Renewable Energy — Facts and Fantasies.   Nicely done, Seth!

I just got home from the TV studio after shooting three hours of videos. Each time I do this, I come  away wondering if there could possibly be more exhausting work. I would have hoped that after all the time I’ve spent recently on radio and TV, I would have become fairly comfortable with a mic/camera in my face, but honestly, I was totally baked after three short hours.

Think we advocates of renewables in the U.S. have trouble? Our friends in the U.K. are running into a buzzsaw of misinformation, like the report “Renewable Energy: Vision or Mirage”, published today by the Adam Smith Institute and Scientific Alliance. The report includes:

“Wind does little to reduce carbon emissions.”

and

“Nuclear and gas are the most viable energy sources for the near future.”

What a remarkable thing to say, when the U.K. has already installed enough wind turbines to provide clean electricity to more than 3.2 million homes, according to RenewableUK, the trade association representing the wind, wave, and tidal energy industries.  RenewableUK also makes the point that I always do about nuclear: even if you consider it safe, it takes a minimum of eight years to permit and build a reactor, and the cost overruns are legendary.  Referring to it as “viable” seems ridiculous.

In April 2010, the UK government introduced their own version of a feed in tariff scheme to help boost our renewable figures and to cut carbon emissions. It is a scheme where homeowners are paid 41.3p for generating electricity with photovoltaic solar panels on their roof, and they are then extra in the case that they don’t use the electricity. Combining the average bill savings with these payments amounts to approximately £1,000 per year at today’s prices. With the scheme lasting for 25 years, the panels will pay themselves off over time, usually 9 to 10 years, and then they will start to generate a healthy income. Our national solar panels company has seen demand for solar skyrocket by over 400% from before the FIT was introduced. (more…)
