How dangerous ARE fracking chemicals really?
November 28, 2014 09:17 AM - University of Colorado Boulder
The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder.
Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground.
Farms as sites for renewable energy
November 21, 2014 07:00 AM - ClickGreen Staff, ClickGreen
UK farms could be a major player in a shift towards a resilient, low-carbon energy system, according to a landmark report launched today by the Farm Power coalition.
The coalition, which is made up of a growing number of farming bodies, businesses and NGOs, are now calling on policymakers and other key stakeholders, including supermarkets, to support the renewable energy vision.
The research carried out by sustainability non-profit Forum for the Future, which leads the coalition, and Nottingham Trent University, found there was at least 10GW of untapped resource across UK farms – equivalent to more than three times the installed capacity of the proposed new nuclear power plant at Hinkley Point C.
UK unveils first waste-fueled bus
November 20, 2014 07:49 AM - ClickGreen Staff, ClickGreen
The UK's first ever bus powered on human and food waste has taken to the road today which engineers believe could provide a sustainable way of fuelling public transport - cutting emissions in polluted towns and cities. The 40-seater Bio-Bus, which runs on gas generated through the treatment of sewage and food waste that's unfit for human consumption, helps to improve urban air quality as it produces fewer emissions than traditional diesel engines. Running on waste products that are both renewable and sustainable, the bus can travel up to 300km on a full tank of gas.
Electric vehicles WILL go mass market. Here's why.
November 16, 2014 08:09 AM - BOB SHETH, Electric Forum
Over the last 100 years there have been a number of attempts from electric vehicle enthusiasts to push them into the mass market. Unfortunately the vast majority of these attempts have failed for a variety of reasons, often out of the control of the market itself, but today we stand in a very different place and electric vehicles will eventually go mass-market. We hereby list five reasons why electric vehicles are here to stay in the longer term: –
There have been enormous leaps in electric vehicle technology over the last 10 years which not only offer greater efficiency but also give the driving public greater confidence. This technology continues to advance at breathtaking speed not only in the area of electric vehicles themselves but also battery technology. In many ways the development of new technologies is putting gasoline vehicles in the shadows and grabbing the headlines.
Uranium mining in Greenland an election year issue
November 14, 2014 09:55 AM - EurActiv
The upcoming general elections in Greenland may see the country moving away from the idea of extracting and exploiting uranium, which the government voted in favour of just a year ago.
Uranium mining, the hottest topic in the the cold, Arctic country in recent years, was put on the agenda by former prime minister Aleqa Hammond in 2013, after 25 years with a 'zero tolerance' policy to mining of radioactive substances and oil drilling.
ENERGY STAR's first multifamily properties announced today
November 13, 2014 08:31 AM - ENERGY STAR
Roughly one-third of the U.S. population lives in the country’s 500,000 multifamily buildings, and they spend $22 billion on energy every year. Until this year, apartment and condo managers lacked the tools to measure how much energy they were wasting and compare their performance nationwide. Meanwhile, energy costs for renters have risen by 20 percent over the past decade.
Today, a new era of savings will be ushered in when the U.S EPA announces the first set of multifamily properties to earn the ENERGY STAR certification. The ENERGY STAR first became available to the sector this September, after a three-year partnership with Fannie Mae to develop the scoring system for multifamily properties.
New study says fracking chemicals are "no more toxic" than common household substances
November 12, 2014 01:21 PM - University of Colorado, Boulder
The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder. Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground. In a new study published in the journal Analytical Chemistry, the research team identified the surfactants found in fracking fluid samples from Colorado, Louisiana, Nevada, Pennsylvania and Texas. The results showed that the chemicals found in the fluid samples were also commonly found in everyday products, from toothpaste to laxatives to detergent to ice cream.
MIT finds the missing piece of the climate modeling puzzle
November 10, 2014 02:58 PM - Genevieve Wanucha, Massachusetts Institute of Technology
In classrooms and everyday conversation, explanations of global warming hinge on the greenhouse gas effect. In short, climate depends on the balance between two different kinds of radiation: The Earth absorbs incoming visible light from the sun, called “shortwave radiation,” and emits infrared light, or “longwave radiation,” into space.
Upsetting that energy balance are rising levels of greenhouse gases, such as carbon dioxide (CO2), that increasingly absorb some of the outgoing longwave radiation and trap it in the atmosphere. Energy accumulates in the climate system, and warming occurs. But in a paper out this week in the Proceedings of the National Academy of Sciences, MIT researchers show that this canonical view of global warming is only half the story.
First Solar Panel Bike Path Planned in Amsterdam
November 10, 2014 07:53 AM - Kevin Mathews, Care2
As one of the biking capitals of the world, Amsterdam can already make a case for being a leader in the green movement. The city is not resting on its laurels, however. Now, biking around the city is getting even greener than just being car-free: a bike path in the suburbs of Amsterdam is getting a major solar makeover.
How would you feel if electric vehicles were the only ones allowed in center cities?
November 9, 2014 04:42 AM - , Electric Forum
The subject of making electric vehicles compulsory in city centres in the UK, and indeed many other areas of the world, is one which keeps popping up time and time again. The Liberal Democrat party in the UK has been pushing for greater adoption of electric vehicles within city centres and, don’t shout this, a ban on diesel and petrol vehicles. This is now something of a hot topic and one which will continue to appear in the political domain as we approach general and local elections.
How would you feel about making city centres a no-go area for petrol and diesel vehicles? Is electric vehicle technology of sufficient reliability to support such a dramatic and controversial move?
