Greece's economic problems linked to its coal-based energy policies
July 4, 2015 07:53 AM - Takis Grigoriou / Greenpeace EnergyDesk, The Ecologist

As Greece prepares for its referendum, Takis Grigoriou takes Greece to task for its highly polluting lignite power sector, its ditching of a successful solar program in favour of more coal, the minimal insulation in its buildings that locks in high fuel bills, and Syriza's failure to tackle these issues. The good news? Greece's latest €1.4bn coal project looks like going unfunded.

Instead of phasing out lignite Greece opted to engage in a long battle to preserve the ailing industry while putting an abrupt end to solar energy development by blocking new applications.

Advertising coming to EV charging stations?
July 3, 2015 05:04 AM - BOB SHETH, Electric Forum

While many electric vehicle owners will find it irritating and annoying to be hit with adverts when charging their vehicles, is this a sign of the times? The fact that many larger companies are willing and prepared to pay for advertising space on “free” charging devices seems to indicate that the marketing industry believes the sector is here to stay. So, will advertising be a help or a hindrance to the industry going forward?

Until the electric vehicle industry cracks the “mass market” it is vital that the cost of services and products is kept as low as possible. There will come a point when costs will have to rise, services will be chargeable and the whole dynamic will be very different than what we see today but, in the meantime, is advertising on “free” charging stations really a hindrance?

Study examines overall carbon cost of fuel from Canadian oil sands
June 28, 2015 06:34 AM - UC Davis via the ECOreport, ECOreport

Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over the oil’s lifetime than fuel from conventional crude sources in the Unied States, according to a study by the U.S. Department of Energy’s Argonne National Laboratory; the University of California, Davis; and Stanford University.

The researchers used a life-cycle, or “well-to-wheels,” approach, gathering publicly available data on 27 large Canadian oil sands production facilities. The study, published in the journal Environmental Science and Technology, found the additional carbon impact of Canadian oil sands was largely related to the energy required for extraction and refining.

Fracking helping utilities reduce reliance on coal
June 23, 2015 07:15 AM - MARIE CUSICK, NPR

When you flip on a light switch, odds are, you're burning coal. But as the fracking boom continues to unleash huge quantities of natural gas, the nation's electric grid is changing. Power plants are increasingly turning to this low-cost, cleaner-burning fossil fuel.

Bill Pentak stands in the middle of a construction site, looking up at his company's latest project towering overhead — a new natural gas power plant.

"This plant was sited precisely where it is because of its access to the abundant, high-quality natural gas that's found a mile to two miles beneath our feet," he says.

Kansas City goes All-In for EV's
June 6, 2015 08:05 AM - BOB SHETH, Electric Forum, Electric Forum

Even though there is a long way to go before electric vehicles are accepted by all motorists, there is no doubt that the Kansas City Power and Light company is putting Kansas City on the map. The company announced very interesting and very ambitious plans to install 1001 electric vehicle charging stations across the area which it serves. This is certainly a very interesting development at a time when advances in electric vehicle battery technology are hitting the headlines but consumers are still concerned about range anxiety.

Will this move make a difference?

As one executive put it “if you install the charging stations they will come” which just about sums it up. The $20 million “clean charging network” will consist of 1001 charging stations which will be able to charge two cars at the time. Not only will this encourage more electric vehicles in the region but it will also greatly help with charging at busy times of the day. The simple fact is that until somebody actually took the plunge and decided to install electric vehicle charging stations we would always be at the beck and call of electric vehicle battery technology.

Renewable Energy Market Employs 7.7 Million People Worldwide
May 19, 2015 09:01 AM - Andrew Burger, Triple Pundit

Renewable energy investment and deployment is paying off, and in spades, when it comes to addressing a basic issue plaguing developed and developing countries alike: an inability to generate jobs that pay a good living wage. Around the world, renewable energy job creation continues to far outpace that for economies overall. Some 7.7 million people are now employed across the global renewable energy value chain, according to the International Renewable Energy Agency (IRENA). That’s up 18 percent from 6.5 million in 2014, the agency noted in its 2015 Renewable Energy and Jobs Annual Review.

Fracking wastewater and the risk to our food
May 3, 2015 06:42 AM - Roy L Hales

Unconventional drilling creates a huge amount of waste, some of which is being sprayed onto farmer’s fields. A 2005 report from New Zealand stated cows grazing on “dump farms” have elevated levels of hydrocarbons. “Cows are allowed to graze on land with high levels of hydrocarbons without any punishment and their food products are allowed to go to market without government testing,” a Green Party MP said last year. It is happening in Canada too. The field above is northwest of Calgary. Former energy consultant Jessica Ernst said, “We are eating & drinking drilling and fracking waste.”

“When they are drilling deep horizontal wells, they go a great distance and this produces a lot of drilling waste. It is toxic. There are a lot of naturally occurring toxics that are brought up. It is often radioactive. I have documentation that the formations they want to frack are radioactive. This comes up with metals and BTEX (Benzene, Tolulene, Ethylbenzyne, Xylenes)  carcinogens plus the mystery additives which companies refuse to disclose,” said Ernst.

On Earth Day, Give Fiber Its Due...
April 22, 2015 02:14 PM - Guest Contributor, James Gowen, Verizon Chief Sustainability Officer

There's a touch of green associated with receiving phone service, using the Internet and streaming video over an all-fiber-optic network. It's not the color of laser-generated light that carries massive amounts of data through all-glass cables directly into homes and businesses. It's green in the sense of how much more environmentally friendly today’s fiber-based telecommunications networks are compared to copper wire and coaxial cable networks. Whether it's energy efficiency or reduced demand for raw materials and other resources, all-fiber networks are a winning strategy on many fronts — including environmental sustainability. As we approach the 45th celebration of Earth Day on April 22, it's a good time to reflect on how network and technology decisions made by major telecommunications companies don't just result in advanced, more reliable services. These decisions can also pay handsome dividends on the sustainability front.

The link between diesel exhaust and lung irritation
March 14, 2015 08:07 AM - European Lung Foundation via EurekAlert

Estoril, Portugal: Researchers in the UK have, for the first time, shown how exhaust pollution from diesel engines is able to affect nerves within the lung. Air pollution is a significant threat to health, they say, and identifying potential mechanisms linking exposure to diesel exhaust and the exacerbation of respiratory diseases may lead to treatments for those affected.

Mr. Ryan Robinson, a PhD student at the National Heart and Lung Institute, Imperial College London, UK, will tell the 13th European Respiratory Society Lung Science Conference today (Saturday) about his work studying diesel exhaust particles and airway sensory nerves. The news comes as the Healthy Lungs for Life campaign, launched by the European Respiratory Society and European Lung Foundation, takes places this year aiming to raise awareness of the importance of breathing clean air.
