How would you feel if electric vehicles were the only ones allowed in center cities?
November 9, 2014 04:42 AM - , Electric Forum

The subject of making electric vehicles compulsory in city centres in the UK, and indeed many other areas of the world, is one which keeps popping up time and time again. The Liberal Democrat party in the UK has been pushing for greater adoption of electric vehicles within city centres and, don’t shout this, a ban on diesel and petrol vehicles. This is now something of a hot topic and one which will continue to appear in the political domain as we approach general and local elections.

How would you feel about making city centres a no-go area for petrol and diesel vehicles? Is electric vehicle technology of sufficient reliability to support such a dramatic and controversial move?

New Mechanism Behind Arctic Warming Revealed
November 6, 2014 08:06 AM - Editor, ENN

We all know that greenhouse gases contribute to global warming, but new research identifies a new mechanism that could turn out to be a major contributor to melting sea ice, specifically in the Arctic region. Scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have studied a long-wavelength region of the electromagnetic spectrum called far infrared. Far infrared is a region in the infrared spectrum of electromagnetic radiation. While it is invisible to our eyes, it accounts for about half the energy emitted by the Earth’s surface. 

Electric Vehicles and charging systems need to be moving forward in harmony
November 5, 2014 05:51 AM - BOB SHETH, Electric Forum

In many ways electric car technology jumped to far too quickly leaving behind electric vehicle charging systems which for many years have been totally inadequate. There has been major concern amongst motorists around the world that even the most technologically advanced electric vehicle would be unreliable if you are not able to charge it when and where you wanted. This has held the electric car industry for some time although thankfully governments around the world are now focusing upon electric car charging networks.

This then begs the question – could electric car chargers be the next growth industry?

MIT finds switching to higher octane fuel would reduce carbon emissions
October 28, 2014 07:15 AM - MIT News

If the majority of light-duty vehicles in the United States ran on higher-octane gasoline, the automotive industry as a whole would reduce its carbon dioxide emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis by MIT researchers.

 

In a study published in the journal Environmental Science & Technology, the team considered a scenario in which fuel is manufactured under a redefined octane rating — the measure of a gasoline’s ability to resist engine knocking during combustion.

What could be better than LED lighting?
October 27, 2014 12:13 PM - ClickGreen staff, ClickGreen

Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow.

Electronics based on carbon, especially carbon nanotubes (CNTs), are emerging as successors to silicon for making semiconductor materials. And they may enable a new generation of brighter, low-power, low-cost lighting devices that could challenge the dominance of light-emitting diodes (LEDs) in the future and help meet society's ever-escalating demand for greener bulbs.

Can the corridors under high-tension lines be important opportunities for conservation?
October 17, 2014 08:06 AM - richard conniff, Yale Environment360

Often mowed and doused with herbicides, power transmission lines have long been a bane for environmentalists. But that’s changing, as some utilities are starting to manage these areas as potentially valuable corridors for threatened wildlife. Nobody loves electrical power transmission lines. They typically bulldoze across the countryside like a clearcut, 150 feet wide and scores or hundreds integrated vegetation management in right-of-way scores or hundreds of miles long, in a straight line that defies everything we know about nature. They’re commonly criticized for fragmenting forests and other natural habitats and for causing collisions and electrocutions for some birds. Power lines also have raised the specter, in the minds of anxious neighbors, of illnesses induced by electromagnetic fields. So it's a little startling to hear wildlife biologists proposing that properly managed transmission lines, and even natural gas and oil pipeline rights-of-way, could be the last best hope for many birds, pollinators, and other species that are otherwise dramatically declining.

How Offshore Wind Farms Affect Marine Species
October 17, 2014 06:07 AM - University of Maryland Center for Environmental Science

Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. In a recent paper, University of Maryland Center for Environmental Science researcher Helen Bailey and colleagues review the potential impacts of offshore wind developments on marine species and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world.

Which Form of Energy is the Cheapest?
October 16, 2014 10:47 PM - Kevin Mathews, Care2

Which kind of power is the cheapest? Listen to energy companies, and they'll insist that traditional forms like gas and coal are the way to go. Of course, they have money invested in keeping the existing systems in business. That's why the European Union commissioned an independent analysis to study the topic. According to the report, wind energy is the most cost-efficient way to supply power. When proponents of non-renewable energy point to costs, they intentionally overlook the overall economic impact that polluting causes. Once experts start to calculate the costs associated with public health and climate change that coincide with burning coal and gas, the true cost is far higher than initially reported. It's both irresponsible and shortsighted to ignore these environmental and health consequences from the equation.

Abundant natural gas will not slow climate change according to new study
October 16, 2014 06:22 AM - Pacific Northwest National Laboratory

A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study appearing today in Nature Advanced Online Publication. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change — and according to government analyses, natural gas did contribute partially to a decline in U.S. carbon dioxide emissions between 2007 and 2012.
