Can renewables supply 100% of world's power by 2050?
October 16, 2014 06:08 AM - Tim Radford, The Ecologist
A global low-carbon energy economy is not only feasible - it could actually double electricity supply by 2050, while also reducing air and water pollution, according to new research. Even though photovoltaic power requires up to 40 times more copper than conventional power plants, and wind power uses up to 14 times more iron, the world wins on a switch to low-carbon energy. These positive findings are published in the Proceedings of the National Academy of Sciences by Edgar Hertwich and Thomas Gibon, of the Norwegian University of Science and Technology Department of Energy and Process Engineering.

Fracking Footprint Seen From Space
October 10, 2014 08:38 AM - ClickGreen Staff, ClickGreen
An unexpectedly high amount of the climate-changing gas methane, the main component of natural gas, is escaping from the Four Corners region in the US Southwest, according to a new study by the University of Michigan and NASA. The researchers mapped satellite data to uncover the nation's largest methane signal seen from space. They measured levels of the gas emitted from all sources, and found more than half a teragram per year coming from the area where Arizona, New Mexico, Colorado and Utah meet. That's about as much methane as the entire coal, oil, and gas industries of the United Kingdom give off each year.
Elephants worth more alive, than when they are poached for ivory
October 9, 2014 08:54 AM - Morgan Erickson-Davis, MONGABAY.COM
Elephants are worth 76 times more when they’re alive than dead, according to a new analysis released this past weekend. The report follows on the heels of findings by WWF that the world has lost 50 percent of its wildlife over the past 40 years, with more than half of African elephants killed for ivory in just one decade. The analysis, conducted through the David Sheldrick Wildlife Trust's iworry campaign, compared the value of elephants to local economies to profits netted through the illegal ivory trade.
How "Natural" are Naturally Labeled Foods?
October 8, 2014 08:46 AM - ClickGreen Staff, ClickGreen
A wide variety of packaged food that carry the label "natural" on US supermarket shelves were found to contain substantial amounts of genetically modified organisms (GMO), according to product testing organization Consumer Reports. Tests on dozens of common food products including breakfast cereals, crisps and infant formula found almost all of them contained recognizable levels of GMOs. The research results has led to Consumer Reports to now call for the mandatory labeling of GMOs in food and a ban on the "natural" label, which suggest products don't contain the controversial ingredients.
Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University
If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.
Connecting Productivity of Office Workers and Climate Change
September 29, 2014 09:57 AM - John Alker, The Ecologist
Energy efficiency in office buildings struggles to gain the attention of top management, writes John Alker - because energy is too cheap to really matter. But with 90% of operating costs spent on staff, a new report shows that green building design makes employees happier and more productive. There would seem to be no connection between the productivity of office workers and the great challenge of climate change. But a report published by the World Green Building Council suggests otherwise.
Reducing global trade would cut carbon emissions
September 27, 2014 11:12 AM - John Weeks, The Ecologist
If the world's leaders really cared about climate change, there's one easy way to reduce emissions, writes John Weeks - drop the obsession with increasing trade, and all the pollution that goes with it. A world based on local production, consumption and finance will be a better one for people and the environment. Let us join Keynes to imagine if we can a world in which goods are 'homespun' and finance is 'primarily national'. If we cannot imagine such a world, there is little hope for the planet. The Obama administration has proposed several ad hoc multi-country economic agreements, and in doing so has abandoned de facto the World Trade Organization (WTO) as insufficiently malleable to its interests.
Chinese Now Emit More Carbon Per Capita Than Europeans
September 24, 2014 09:39 AM - Jeremy Hance, MONGABAY.COM
Last year, the people of China emitted more carbon per person than those in the EU, according this year's Global Carbon Budget. The report, updated annually, also found that global emissions jumped 2.5 percent last year and are set to hit a record high of 40 billion tonnes this year. The findings highlight how little global society has done to stem emissions, despite numerous pledges and past global agreements.
The Future of Vertical Farming
September 19, 2014 06:15 AM - Allison Winter, ENN
From big company agricultural farming, to communal farming or even personal agronomy, the business of growing crops for an expanding global population will be crucial in the near future. The two most important resources needed to run these farms are one, water, and two, land. But these resources often come at a premium, especially with growing populations and increased food demand. Farmers and researchers have already started leaning towards genetic engineering and industrial processing to help with their crop yields, but a new solution in agribusiness is emerging. Vertical farming.
