Why don't building owners install modern controls?
May 24, 2014 08:08 AM - Roger Greenway, ENN
Commercial buildings use large amounts of electricity and natural gas. Significant reductions in energy use can be achieved by installing new modern systems but this requires a significant capital cost, It is possible to install modern control systems at much lower cost and these can also significantly reduce energy use, and improve comfort at the same time! A new study by the Pacific Northwest National Laboratory shows that commercial buildings could cut their heating and cooling electricity use by an average of 57 percent with advanced energy-efficiency controls, according to a year-long trial of the controls at malls, grocery stores and other buildings across the country. The study demonstrated higher energy savings than what was predicted in earlier computer simulations by the same researchers.

The world's first community-owned tidal power turbine has started exporting electricity to the local grid, the Scottish Government has announced.
Volvo and Electric charging on the go
May 23, 2014 08:18 AM - Bill DiBenedetto, Triple Pundit
There are electric satellites from Boeing and electric planes from Airbus, so why not electric roads, brought to you by Volvo Group? Volvo, in collaboration with the Swedish Transport Administration, is studying the potential for building electric roads where city buses—built by Volvo, of course—can be charged from electricity in the road while the bus is in operation.
African nation seeks $1 billion to save its rainforest

The Democratic Republic of Congo is seeking a billion dollars for a plan to protect up to 9 million hectares of rainforests, reports the Financial Times. In a presentation given at the Houses of Parliament on Tuesday, DR Congo Minister of Environment Bavon N'sa Mputu Elima said his country needed foreign assistance to protect forests. He cited Indonesia as a precedent for such an approach.
Climate change threatens US landmarks

The growing consequences of climate change are putting more than two dozen of the most iconic and historic sites in the US at risk, according to a new report. From Ellis Island to the Everglades, Cape Canaveral to California's César Chávez National Monument, a lengthy list of treasured sites is being threatened by the effects of climate change, including rising sea levels and fires.
Glacial Water Flows
May 22, 2014 07:53 AM - Harriet Jarlett, Planet Earth Online
Subglacial lakes in Antarctica might have nutrient-rich groundwater flowing into them, say scientists investigating the origin of the water in ice streams. Ice streams are huge, fast-flowing glaciers that meander across Antarctica. They are responsible for nearly all of the Antarctic's contribution to sea-level rise, yet scientists have little understanding of where the water flowing through them comes from. This means that the contents of the subglacial lakes which lie underneath these streams is also a mystery.
Winds of Environmental Change in China
May 22, 2014 07:51 AM - Alex Wang and Benjamin van Rooij, UCLA
China's national legislature has adopted sweeping changes to the country's Environmental Protection Law, revisions that have been hailed as major steps toward saving China's environment from rampant degradation. The authorities will now have stronger enforcement powers, including the right to detain persistent violators for up to 15 days and to fine polluters more heavily than before. Some legally registered civil-society organizations will now be able to initiate public-interest litigation as well.
Technology reducing cost of solar panels by half

A world expert on solar panels will today outline how his pioneering work is set to significantly improve the performance of solar panels whilst simultaneously contributing to their cost being reduced by half. The technology will be commercialized within the next five years.
Longer growing season does not yield growth increase for trees and shrubs
May 21, 2014 09:29 AM - Robin Blackstone, ENN
As the earth's temperatures rise, some have speculated that trees and shrubs in the colder climates might experience and increase in growth as a result of the extended growing season. "Not so," says a recent study authored by a University of Washington biology and applied mathematics postdoctoral student. Her study demonstrates that bushes achieve less yearly growth when cold winter temperatures are interrupted by warm spurts that trigger growth.
Antarctica dances to Carole King's "The Earth Moves Under My Feet"
May 20, 2014 02:07 PM - Robin Blackstone, ENN
Antarctica has apparently been living by the lyrics of Carole King's 1971 hit song "The Earth Moves Under My Feet". According to a study from Newcastle University in the United Kingdom, Antarctica has been moving "rapidly". Recently published in Earth and Planetary Science Letters, the study explains why the upward motion of the Earth's crust in the Northern Antarctic Peninsula is currently taking place so quickly. While earlier studies have shown the earth is 'rebounding' due to the overlying ice sheet shrinking in response to climate change, GPS data is suggesting otherwise. The international research team led in part by Newcastle researchers has revealed that this land is rising at a remarkable rate of 15mm a year.
