Wave Energy looks very favorable from a cost standpoint
January 8, 2015 06:59 AM - Ted Brekken, Oregon State University

A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.

The findings, published in the journal Renewable Energy, confirm what scientists have expected – that wave energy will have fewer problems with variability than some energy sources and that by balancing wave energy production over a larger geographic area, the variability can be even further reduced.

Why we need to reduce our "hidden water" usage
January 5, 2015 07:46 AM - ClickGreen staff, ClickGreen

The Institution of Chemical Engineers (IChemE) is urging coordinated action to reduce the amount of hidden water used in food and drink production – estimated at up to 1.8 million litres per person every year equivalent to an Olympic size swimming pool. Each person consumes between 2,000-5,000 litres of water embedded in their food, every day – or between 730,000-1,825,000 million litres annually. Currently, around 90 per cent of all freshwater is used by agriculture (70 per cent) and industry (20 per cent), leaving just 10 per cent for domestic use.

Plastic bag ban may be delayed in California
December 31, 2014 08:14 AM - Leon Kaye , Triple Pundit

California Senate Bill 270, passed by the state legislature and signed into law in September, would ban many retail stores from dispensing single-use plastic bags as of July 1, 2015. But in another example of a special interest perverting democracy when it does not get its way, the Plastics Industry Trade Association (SPI) has announced it has collected over 800,000 signatures to qualify for a statewide up-or-down vote in November 2016. Once that tally is confirmed, the July ban would be postponed until the following year.

You probably saw the sign gatherers at stores such as Target, where I was greeted with an appeal to sign my name and take sides with the “American Progressive Bag Alliance” in order to reverse this “backdoor deal” — until the fellow with the clipboard saw my reusable bags. “Oh, you’re one of those,” he said with an eye-roll, because as you know, someone like me who likes to wear labels, shops at Costco and makes mac-and-cheese out of a box (when no one is looking) is such a hippie.

Don't put old electronic items in the trash!
December 30, 2014 08:36 AM - NationSwell, Care2

Chances are, many Americans received shiny, new gadgets for the holidays — meaning their old electronics will either collect dust in a closet somewhere or get tossed out.

These unwanted laptops, tablets and printers contribute to the enormous amount of electronic waste, or “e-waste,” that continually piles up in our landfills. According to the EPA, 3.4 million tons of tech gear was trashed in 2012, and unfortunately, only 12.5 percent of e-waste is currently recycled.

The mystery of the disappearing plastic trash in the oceans solved!
December 27, 2014 08:49 AM - Lizabeth Paulat, Care2

Many of us have seen the photos of plastic refuse in the ocean, the large islands of bags and waste that collect at tidal crossroads. Yet when scientists took a survey of the ocean earlier this year, they found a suspicious amount had disappeared. Was it just our good luck that pollution was decreasing? Hardly. It had simply been sinking, breaking apart and embedding itself in the sediment.

Fibers of microplastic, which are similar in diameter to a human hair, have sunk into deep water reserves across the world. For every bag floating across the ocean’s surface, there’s much more of the stuff laying in the ocean floor underneath. How much plastic is there? Well, according to the research, it’s so widespread that they’ve estimated microplastic is on every kilometer of the sea floor across the globe.

Renewables Dominate New US Electrical Generating Capacity
December 24, 2014 10:01 AM - Clean Techies Staff, Clean Techies

According to the latest “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects, wind energy and solar power combined provided over 70 percent (71.82%) of the 873 megawatts (MW) of new U.S. electrical generating capacity placed into service in November 2014. Specifically, three wind farms came on line last month, accounting for 333-MW of new generation in service. These included Stella Wind Farm’s 182-MW Panhandle Wind Farm Phase II expansion in Texas and the 150-MW Origin Wind Energy project in Oklahoma. New wind generating capacity this year thus far has more than doubled that for the same period in 2013 (2,525-MW vs. 1,112-MW).

Going green has benefits beyond being good for you and the planet!
December 22, 2014 08:00 AM - ClickGreen staff, ClickGreen

You know that going green helps the environment and often your bank account, but it can also play a key role in reducing accidents. Green lifestyles are generally healthier ones, so don’t forget about that bonus perk when you go eco-friendly. Whether it’s reducing the amount of chemicals in your home, reducing the pesticides in your food, or avoiding the need for a DWI attorney because you never drive (especially not under the influence), here are a few ways eco-friendliness equates to fewer accidents: 

1. No chance of a car crash

Statistically, taking public transportation such as a bus or train, or walking or cycling, is much less dangerous than taking a car. Distracted driving is on the rise; just take a look at the official government (UK) Distraction.gov site for statistics on accidents caused from phones, radios, food and sleepiness. A greener approach to getting around is simply less prone to accidents than taking a car.
 

New York State to Ban Fracking Due to Health Risks
December 19, 2014 12:09 PM - Jan Lee, Triple Pundit

This week, New York state joined the growing list of states and communities to ban hydraulic fracturing (fracking) within its boundaries. After years of contentious debate over the safety of fracking, Gov. Andrew M. Cuomo’s announcement Wednesday that he would move to unilaterally ban fracking was not completely unexpected. Still, environmental groups are counting the Department of Health’s report that “[high volume hydraulic fracturing] should not proceed in NYS” as a victory.

The role of taxes (and EV's) in reducing CO2 emissions from cars in Europe analyzed
December 19, 2014 08:43 AM - EurActiv

The Netherlands had the lowest CO2 emissions from new cars in the European Union last year, thanks to its tax regime favouring fuel economy and low-carbon vehicles.

Germany and Poland are among the countries with the highest C02 emissions from new cars and the weakest national tax policies, a report by NGO Transport & Environment has found.

Cars are responsible for 15% of Europe’s total CO2 emissions and are the single largest source of emissions in the transport sector. 

New process turns biomass 'waste' into chemical products
December 17, 2014 03:13 PM - Elizabeth K. Gardner, Purdue University

A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers from Purdue University's Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities. Lignin is a tough and highly complex molecule that gives the plant cell wall its rigid structure.
