New York City to Use Food Waste to Heat Homes
December 27, 2013 08:22 AM - Gina-Marie Cheeseman, Triple Pundit
New York City will reduce the amount of food waste sent to landfills by converting it into energy. Last week, Deputy Mayor Cas Calloway announced that the city will partner with Waste Management to deliver pre-processed organic waste food to Newtown Creek Wastewater Treatment Plant where it will be added to wastewater sludge to increase biogas production. The biogas by-product will be converted into renewable natural gas for both residential and commercial use through a partnership with National Grid, an international electricity and energy company. Through this project, enough energy could be produced to heat almost 5,200 New York city homes and reduce annual greenhouse gas (GHG) emissions by over 90,000 metric tons, equivalent to removing almost 19,000 cars from the road.
COLLEGIATE CORNER: The Benefits of Laundry-to-Landscape Greywater Systems
December 26, 2013 04:28 PM - Madeline Valinski, University of Delaware, Class of 2015, Environmental Studies
Approximately 30% of household water use is for outdoor use in the form of garden irrigation. Outdoor water usage is very seasonal, according to the U.S. Environmental Protection Agency, and outdoor water usage is highest when water availability is the lowest due to drought conditions and heat. The top three uses of water in the household are for landscaping, sewage, and laundry. Yet a simple laundry-to-landscape system could reduce one of these high water wasters. A laundry-to-landscape system might not be the only step to make the garden water neutral; approximately 15% of household water use is for laundry, which could at least reduce outdoor water usage by 50% if a laundry-to-landscape system were installed.
The "state" of Energy Efficiency
December 26, 2013 09:47 AM - Mary Mazzoni, Triple Pundit
Conversations about energy use in the U.S. often revolve around expanding domestic production or spurring renewables. It’s easy to forget another significant piece of the puzzle — energy efficiency. In its 2013 scorecard, the American Council for an Energy-Efficient Economy (ACEEE) ranks the most energy-efficient states based on policy and program efforts that improve efficiency in homes, businesses, industries and transportation systems.
A little less coal for China
December 24, 2013 09:02 AM - Kieran Cooke, Ecologist
Coal mining companies in Australia have been enjoying the good life in recent years, making millions of dollars from feeding the seemingly insatiable energy appetites of Asia's tiger economies - particularly that of China. But a new report by the Smith School of Enterprise and the Environment (SSEE) at Oxford in the UK warns that Australia's coal mining party could be coming to an end.
Out with the old and in with the new--light bulbs that is!
December 23, 2013 09:25 AM - Robin Blackstone, ENN
As of January 1, 2014, 60 and 40 watt incandescent bulbs will no longer be manufactured or sold in the United States. Retailers will sell out what is on their shelves and not restock incandescents. George W. Bush signed the phase-out, which was called for by The Energy Independence and National Security Act, in 2007. The bill also includes improvements in energy efficiency for lighting and appliances many of which have been in stores for several years.
Brown trout crowding out native brook trout
December 20, 2013 08:50 AM - Editor, ENN
Native brook trout, Salvelinus fontinalis, populations could be at risk as a result of the introduction of Brown trout, Salmo trutta, according to a new U.S. Geological Survey study. Both species are valuable sport fish that coexist in many parts of the world due to stocking introductions.
More than 40% of Scotland's energy demand is now met by renewables
December 19, 2013 09:18 AM - ClickGreen Staff, ClickGreen
Scotland’s renewable electricity output has reached record-high levels, according to official statistics released today. The figures, published by the Department of Energy and Climate Change, show that renewables met a record-breaking 40.3 per cent of gross electricity consumption in 2012, confirming that Scotland is on track to meet its interim target of 50% by 2015.
Damming the Congo
December 18, 2013 09:42 AM - Robin Blackstone, ENN
The Democratic Republic of Congo (DRC) is looking to capture the more of powers of the Congo River in what will be the largest and most powerful hydroelectric dam in the world. The Grand Inga Hydropower Project will produce up to 40,000 megawatts of electricity, doubling current dam champion, Three Gorges in China. The dam will generate more than one third of the electricity currently produced in Africa as it captures the force of the 1.5 million cubic feet per second cascading into the Atlantic Ocean.
EPA settles an unsettling amount of reactive hazardous waste in Oregon
December 17, 2013 08:29 PM - Staff, ENN
Oregon Metallurgical of Albany and TDY Industries of Millersburg have agreed to pay a combined $825,000 to resolve alleged violations related to the improper storage, transportation, and disposal of anhydrous magnesium chloride, a reactive hazardous waste that poses fire and explosion threats. The EPA asserts that both companies must improve their hazardous waste management practices and upgrade their record keeping for wastes generated at their facilities to avoid potential injuries and accidents.
COLLEGIATE CORNER: Must we drink bottled water?
December 16, 2013 04:10 PM - Alyson Leppla, Earth Science Education, Class of 2015, University of Delaware
More than 780 million people lack access to safe drinking water, two and a half times the population of the United States. More than half of all Americans drink bottled water, yet almost every U.S. household has access to safe drinking water.
