As UN Climate Conference Approaches, Renewable Energy Makes Major Global Gains

Clean energy is “key” to climate action, according to a senior advisor to President Obama in a blog post published last week, which discussed the United States’ official greenhouse gas emissions-cutting target to the United Nations. The proposal formalizes a U.S. commitment to reducing emissions 26 to 28 percent below 2005 levels by 2025.

Graphene Light Bulb Expected to Last Longer, Be More Efficient, Save Money and Energy

A lightbulb with lower energy emissions, longer lifetime and lower manufacturing costs, and made with graphene — said to be the first commercially viable consumer product using the super-strong form of carbon — is poised to hit the market this year, thanks to a University of Manchester research and innovation partnership.The bulb’s developers — a Canadian-financed company called Graphene Lighting — expect the dimmable bulb to use 10 percent less energy than conventional bulbs, last longer and be priced lower than some LEDs, at roughly $20 each. It was designed at the University of Manchester, where the revolutionary material was discovered. The University’s National Graphene Institute was opened this month.

Sustainable Investments Outperforming Traditional Investments, Reports Morgan Stanley

A new report from the Morgan Stanley Institute for Sustainable Investing finds that investing in sustainability has usually met and often exceeded the performance of comparable traditional investments, both on an absolute and risk-adjusted basis, across asset classes and over time. “We believe sustainable investing will be a key in the mobilization of private capital towards addressing global challenges, but the growth and development of this space remains hampered by a lingering perception that sustainable investments require a financial trade-off. Our review addresses the investment performance concern head-on, and the findings are very positive,” said Audrey Choi, CEO of the Morgan Stanley Institute for Sustainable Investing.

Here’s How Satellites Are Saving the World’s Forests

The world’s besieged forests have found friends in high places — in this case, very high. Remote-sensing satellites keep constant watch from hundreds of miles above the earth, collecting data that — when combined with information sharing and human networks around the world — can be used to preserve the world's forests, which are disappearing at an alarming net loss of 12.8 million acres each year (an area the size of Costa Rica).Although deforestation has slowed slightly since the 1990s thanks to conservation efforts, the situation remains dire.

An Unlikely Pair: Farmers and Big Data Team Up to Address Food Security

The United States agriculture industry faces a changing climate, diminishing water supply, and a rapidly growing population. To address these issues, farmers are having to move into the 21st century, one tech advancement at a time."We live in a complicated world and there's been a lot of talks these days about getting to 2050 and feeding over 9 billion people," said A.G. Kawamura, the former California Secretary of Agriculture, co-chair of Solutions from the Land, and a third-generation farmer. "We have the capacity but we don't have the will to do it. Logistics haven't been put into place."

On-Site Water Recycling Could Create Drought-Resilient Homes in California

California builders, water & sewer agencies and homeowners are one step closer to being able to construct bona fide drought-resilient homes.Nexus eWater, maker of home water and energy recyclers, has received certification to the NSF/ANSI 350 global standard for residential grey water treatment for its ‘NEXtreater’ home water recycler. The water recycler is capable of safely recycling two out of every three gallons of grey water in the home for non-potable, approved uses.Grey water is drain water from showers, laundry and hand sinks and is the largest potential source of on-site water in homes — typically, this makes up two-thirds of indoor water.The potential water savings associated with in-home grey water recycling are “unprecedented”, Nexus eWater says.
