The extreme weather patterns and environmental occurrences experienced across the Asia Pacific region have brought to the forefront the urgent need for countries to work together and reach an agreement on actionable solutions to limit global warming. Examples of recent incidents include drought and severe haze in Southeast Asia, smog in Beijing and the serious floods in Chennai.
One can assume that battery electric vehicles (EV) are cleaner than traditional gasoline fueled cars, but do they really reduce the emissions that fuel climate change?Credit: Tomwang112According to a study by the Union of Concerned Scientists (UCS) comparing them to gasoline cars over their lifetime, the answer is yes.Over their entire lifetimes — from manufacturing to driving to disposal — battery electric cars produce half the global warming emissions, on average, of comparably sized gasoline cars. In addition, driving a battery electric vehicle is cleaner than the average gasoline vehicle on global warming emissions everywhere in the country, and has been improving over the last three years.
Hydrogen is the fuel of the future as it is friendly to the environment, unlike other fuel sources that emit harmful gases into the atmosphere to add to global warming. Thus, this clean green source of power is being excellently utilized in some upcoming vehicles that run on hydrogen fuel cells. Check out some of these hydrogen-powered, zero-emission rides being introduced in the auto market.
Carmakers are launching more electric cars and building their own networks of charging stations, but can the EV overcome the triple threat of low range, long charging time, and high cost?
Ten years ago, a mass-produced car that could get people where they needed to go without contributing to global warming seemed like utopian technology, but in 2013 the battery electric vehicle (EV) is quite real.
Mitt Romney’s acceptance speech at the Republican National Convention last week ought to serve as an urgent wake-up call to anyone that cares about America’s energy, environmental, and economic future. At the podium, Romney chided President Obama on global warming, and his hoped-for GOP administration is advancing an “energy independence” plan built much more on the polluting industries of the past than the innovative clean technologies of the present and future. Somehow, global warming, renewables, and other clean-tech pursuits have become some of his favorite punch lines.
During the past few months, electric vehicles have been assailed by partisan politicians and pundits as too expensive, potentially unsafe, and unlikely to ever be popular enough to reduce global warming.
Here in Portland, EV advocates and researchers see things differently. They see a lot of progress in recent years and predict a bright future — a future that will be discussed at a series of events called EV Week, beginning Monday, June 19.
Do wind farms cause global warming? The short answer is no. But you wouldn’t know that from reading several media interpretations (or misinterpretations) of a short study published recently by a University of Albany scientist that appeared in Nature Climate Change.
Apparently, the flap began when Fox News published a story under the headline “New Research Shows Wind Farms Cause Global Warming.” The story cites a brief study of an area in west central Texas where four of the world’s biggest wind farms are located.
The last few years haven’t been great for clean technology. Implementing cleaner ways of doing things has been going fast but than needed, and even several United Nations global warming summit have failed to come up with ways for industries to limit carbon emissions. While governments haven’t tackled global warming to an ideal or even adequate degree yet, there’s been a ton of innovation from countless businesses. Let’s look at some of the ideas that will shape the future of clean energy.
Stanford University Professor Mark Z. Jacobson recently published a new paper in the journal Energy & Environmental Science, “Review of solutions to global warming, air pollution, and energy security.”
Peter A. Darbee, a utility executive who is ultimately responsible for keeping the lights on for 15 million people, has a message some may not want to hear:
“Climate change is real, it’s urgent, it’s most likely a result of human interactions and what human beings have done in their emissions to the atmosphere, and the need for action is now.”
