and more energy-efficient process for removing greenhouse gas from power plant emissions has been developed by a multi-institution team of researchers.
Power generating plants are the single largest source of carbon dioxide (CO2) a greenhouse gas that traps heat
According to the U s. Environmental protection agency coal-and natural gas-fired plants were responsible for one-third of U s. greenhouse gas emissions in 2012.
That's why the agency has proposed rules mandating dramatically reduced carbon emissions at all new fossil fuel-fired power plants.
MECS provide a new way to capture carbon with fewer environmental issues says Roger D. Aines leader of the fuel cycle innovations program at Lawrence Livermore National Laboratory (LLNL) and a co
Capturing the world's carbon emissions is a huge job; we need technology that can be applied to many kinds of carbon dioxide sources with the public's full confidence in the safety and sustainability.
Aines says that the MECS-based approach can also be tailored to industrial processes like steel and cement production significant greenhouse gas sources.

Between the crowded population, rocky terrain, steep hills that often give way to landslides, and the periodic floods, the locals have had to resort to energy-inefficient terrace farming.
Beyond air quality and climate change mitigation benefits, California abundant renewable energy resources provide energy with zero marginal cost and zero fuel price volatility to our citizens,
To avoid the perverse outcome of curtailment of zero-marginal-cost, greenhouse gas-free renewable resources, we need to absorb gigawatt-hours'worth of midday solar energy for reuse later in the day or the week.

#Solar desalination (Nanowerk News) When graduate student Natasha Wright began her Phd program in mechanical engineering, she had no idea how to remove salt from groundwater to make it more palatable,
Wright began designing an electrodialysis desalination system, which uses a difference in electric potential to pull salt out of water.
This type of desalination system has been around since the 1950s, but is used typically only municipally, to justify its costs.
While other companies are already installing desalination systems across India, their designs are intended to be powered grid.
Shes designed a village-scale desalination system that runs on solar power. Since her system is powered by the sun,
Its useful to install a small-scale desalination system where people are so spread out that its more costly to pump in water from a municipal plant,
or have long-term environmental effects like GMOS, affirms Ursula Hudson, member of the Executive Committee of Slow food International l

#DNA mutations get harder to hide Rice university researchers have developed a method to detect rare DNA mutations with an approach hundreds of times more powerful than current methods.
While the biodegradability of these materials will have a positive impact on the environment, Ma says the flexibility of the technology can lead to widespread adoption of these electronic chips. ass-producing current semiconductor chips is so cheap,
