From Guest Blogger Alia Haley: 7 Ways Homeowners Can Power Their Homes with Renewable Energy
| May 15, 2012 | Posted by Alia under Renewables - Science |
You can see lots of attention is focused towards alternative and renewable energy systems. This is due to the soaring energy costs and the need to decrease the climate change effects over earth. Though these solutions may seem complicated for the homeowners in their daily chores, however, the fact is that they are now becoming more accessible to common man. There are number of options available for homeowners which can prove pretty affordable financial investment. Also, by treading these paths, you can benefit from state and federal tax and avail the utility rebates and incentives. The below are the top seven ways which the home owners can heat and power their homes via renewable energy systems.
Do Wind Turbines Cause Health Issues?

Patricia A. Holden of West Dennis, MA writes:
I am concerned about the big push for industrial wind turbines in this country. I frequently visit a friend in Falmouth, Massachusetts who has had three of these turbines installed within in a mile (one is less than 1/2 mile) away from his home. He and his neighbors are having health issues as a result of the operation of these turbines so close to their homes……Please be sure that your research and understanding is all-encompassing before you continue to advocate wind energy.
Thanks for this, Patricia. Though I’m certainly not an expert on the subject, I am aware of Wind Turbine Syndrome (WTS), controversial as it is. Read More
Living Small — A Christmas Gift for Planet Earth
| December 26, 2011 | Posted by Craig Shields under Sustainability |
To wrap our wits around where we truly are as a species and who we need to be to avoid the brunt of the catastrophes heading our way in the 21st Century, let’s observe: How do we actually behave with respect to our consumption of energy?
The answer, generally, is that only a very small minority of people have gotten the message that what they’re doing matters. Almost no one thinks before turning on a light: “I can flip this switch if it’s really too dark to see, and it’s OK to spend that energy if I need to. But if I don’t need to, I shouldn’t, because the world will be a slightly better place if I don’t.” Or: “I could open this (petroleum-derived) plastic container of creamer for my coffee, but isn’t there an open jug of milk within easy reach?” Or: “Walk or ride?” “Bike or car?” — or the dozens of other choices we make on a minute-to-minute basis. Very few people have gotten the message that their personal decisions to use energy actually matter — that they come at a cost to all of us — and worse, that this cost is far higher than we had previously imagined.
Perhaps we can liken this behavioral issue to littering. Read More
Electric Vehicles and CO2 Emission Abatement
| December 22, 2011 | Posted by Craig Shields under Electric Vehicles |
Frequent commenter Glenn Doty writes:
What would really be nice is an infographic comparing the cost of mitigating CO2 with various alternatives… just to put the different alternatives into proper perspective.
For instance, how much more does it cost to abate CO2 emissions by setting up a rooftop solar panel in NJ as compared to installing additional insulation in an office building in Texas or setting up a wind farm in the Dakotas?
This would be extremely instructional to your readers in terms of what policies would make more sense… and it would be fun to look at how you graph the negative CO2 abatement value of EV’s.
I respond:
Ha! I was reading along here, wondering when you were going to make your point about EVs, and lo! (a good word for the season), there it was.
Seriously, please send me a high-level treatment of your reasoning.
At a minimum, there are two things I don’t get. Read More
Renewable Energy in Europe
| December 22, 2011 | Posted by Craig Shields under Renewables - Business |
I’ll be in Europe from April 26th through May 10th, 2012, attending conferences, meeting colleagues known to me now only through Skype, and conducting interviews for my third book, “Renewable Energy – Following the Money.” In fact, including a robust European presence in the book is vital to telling the story. Where investors may be sitting on the sidelines in the U.S., this is most certainly not the case elsewhere in the world. Europe is proving to be a critically important part of the world in this regard — both for implementing existing clean energy technologies, and as a breeding ground for innovation as well.
Let me take this opportunity to ask you for suggestions. I’ll have plenty of time between conferences and strolls up the Champs Elysees. If you have any connections to people who are in the process of making a difference in the deployment of renewables in Europe, please let me know, and I’ll try to arrange to meet them.
I plan to start in Paris, then head east and south, winding up in Rome. Having said that, detours are always possible. I’d like to speak with entrepreneurs, investors, leaders in government, executives in the energy and automotive industries, top consultants and industry analysts, as well as those directly related to finance and the economy. Tres bien.

Global nuclear capacity has remained flat in growth in the last decade, the worldwide operational installed capacity increased insignificantly from 370 GWe at the end of 2005 to 375 GWe at the end of 2010. Nuclear capacity in the OECD countries peaked in 2006 at 2,259 TWh and declined to 2,136 TWh in 2009. A severe earth quake and tsunami in March 2011 that ravaged the pacific coast of northern Japan resulted in devastating incident in Fukushima Daiichi nuclear power plant.
Following this incidence several countries have announced safety reviews of their nuclear power programmes. Many countries have cancelled nuclear power plans and some are considering closing current plants. While this nuclear meltdown is happening, the global growth in energy from solar, wind, biomass, geothermal and other renewable sources has been 30-40 percent per annum of recent. Currently global growth in deployment of solar PV is the highest standing at 60 percent, this is followed by wind power at 27 percent, then biofuel at 18 percent and then biomass at 7 percent. These trends predict the world will be a nuclear free world.
Solar Goes Mainstream
| December 15, 2011 | Posted by Craig Shields under Photo-voltaics |
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.
Renewable Energy: Vision or Mirage
| December 12, 2011 | Posted by Craig Shields under Wind Energy |
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.
How Many Electric Vehicles Can Off-Peak Power Charge?
| December 11, 2011 | Posted by Craig Shields under Electric Vehicles |
Does anyone know how many kilowatt-hours we in the U.S. dump back to ground each night? If so, please comment, and add a link to the source. Cycling coal plants shortens their lives and adds to the cost of maintenance, and is therefore unappealing. But I’m having the devil’s own time coming up with this datum.
The use of off-peak power is directly relevant to the case for EVs. Read More
Onshore Wind at Grid Parity by 2016
| December 6, 2011 | Posted by Craig Shields under Uncategorized, Wind Energy |
According to Bloomberg, New Energy Finance, improved efficiencies and declining costs will make the average wind farm cost-competitive with coal, gas, and nuclear by 2016 (the best ones already are there). According to Justin Wu, the firm’s lead wind analyst:
The press is reacting to the recent price drops in solar equipment as though they are the result of temporary oversupply or of a trade war. This masks what is really going on: a long-term, consistent drop in clean energy technology costs, resulting from decades of hard work by tens of thousands of researchers, engineers, technicians and people in operations and procurement. And it is not going to stop: In the next few years the mainstream world is going to wake up to wind cheaper than gas, and rooftop solar power cheaper than daytime electricity. Add in the same sort of deep long-term price drops for power storage, demand management, LED lighting and so on – and we are clearly talking about a whole new game.
