    EVs Powered By Coal Are More Polluting Than Gasoline Cars
    (10 May '18)

    Will electric vehicles really lead to cleaner air and healthier people? Only if they are coupled with cleaner ways of generating electricity, scientists say in a new study today. It's a familiar back-and-forth: Advocates alternative energy vehicles point to their positive environmental qualities, such as reducing carbon emissions from the tailpipe. Their opponents point out the hidden costs, such as the fact that the energy for electric cars comes largely from burning coal. Scientists want to attach some hard numbers to this debate. And so a team led by Christopher Tessum, an environmental engineer at the University of Minnesota, Minneapolis, set out to study the effects on human health of various alternative ways to power a car. Their findings are presented today in the Proceedings of the National Academy of Sciences. The researchers investigated ten alternatives to gasoline - https://twitter.com/search?q=gasoline&src=typd .

Jason Hill, study co-author and environmental engineer at the University of Minnesota, says it's important to note that this is a study about pollutants and how they affect human health—not about climate change. The findings showed a dramatic swing the positive and negative effects on health based on the type of energy used. Internal combustion vehicles running on corn ethanol and electric vehicles powered by electricity from coal were the real sinners; according the study, their health effects were 80 percent worse compared to gasoline vehicles. However, electric vehicles powered by electricity from natural gas, wind, water, or solar energy might reduce health impacts by at least 50 percent compared to gasoline vehicles. EV batteries are a problem, too, but a changing one. According to Tessum, previous studies have suggested that emissions from electric car battery production make such vehicles worse for public health than gasoline vehicles, even when the electricity to power them comes from non-polluting sources. In the future, Tessum says, the team wants to explore the potential impacts of alternative fuel use outside the United States.

    For electric vehicles, combustion emissions occur where electricity is generated rather than where the vehicle is used. In China, 85 percent of electricity production is from fossil fuels, about 90 percent of that is from coal. The authors discovered that the power generated in China to operate electric vehicles emit fine particles at a much higher rate than gasoline vehicles. However, because the emissions related to the electric vehicles often come from power plants located away from population centers, people breathe in the emissions a lower rate than they do emissions from conventional vehicles. Still, the rate isn’t low enough to level the playing field between the vehicles. In terms of air pollution impacts, electric cars are more harmful to public health per kilometer traveled in China than conventional vehicles. The researchers estimated health impacts in China using overall emission data and emission rates from literature for five vehicle types—gasoline and diesel cars, diesel buses, e-bikes and e-cars—and then calculated the proportion of emissions inhaled by the population. These are the wave of the future when it comes to transportation, and new models are being released to go at faster speeds. Everyday drivers can soon seek out Edyne vehicles for their own lives. For now, it is at least nice to see a business doing its part to help the environment. This may very well be the start of something grand in the world as people begin to fight environmental concerns one electric truck at a time. Log in or Create Account to post a comment. Publisher: Dr. Rubert Jones As a veteran myself, a chiropractor and as someone who spent a year working for the Veterans administration office, I learned that there are many benefits veterans can receive. Oftentimes due to bureaucracy, veterans do not get those benefits in a timely manner. Here is a method I have found to treat veterans with their pains through a chiropractor and how to get that treatment as quickly as possible using your benefits. When Can the VA Reduce a Veteran's Disability Compensation Benefits?

    It is very important to do research before purchasing an electric green auto. We believe that we have created the most comprehensive site to date to make eco-friendly products, services, and information available to individuals who wish to live a green, more eco-friendly lifestyle. Our site offers a very broad and diverse array of eco-friendly products as well as comprehensive, authoritative information and environmental education.

Publisher: EnviroCitizen Why Use Green Electric ? Green electricity is a wonderful alternative to conventional electric companies. Green electricity is generated through renewable sources, such as solar energy, thermal energy, geothermal energy and wind power. While it does take some energy to manufacture energy this way, the energy that they generate quickly and significantly surpasses the impacts of manufacturing them. March 20, 2006 Earth & Sky--A Radio Network and Website Every day, over three million people learn about sustaining a vibrant and healthy planet at Earth & Sky. Joseph Romm is author of "The Car and Fuel of the Future," a 2004 report to the National Commission on Energy Policy. He is also author of the book The Hype About Hydrogen: Fact and Fiction in the Race to Save the Climate. Earth & Sky's Jorge Salazar spoke with Romm in March 2006 about what the car of the future might be. Salazar: Dr. Romm, thank you for speaking with me today. What is the car of the future? Romm: I think we have two major, related problems that are going to drive transportation in the future. The first is oil. We're increasingly dependent on imported oil from dangerous regions of the world. And I expect that the price of oil and gas will, by and large, keep going up, with some bumps, over the next 10 to 20 years. And, perhaps more importantly, are the greenhouse gases that we keep pouring into the atmosphere from burning fossil fuels like oil.

    You can be assured that this particular toy won't gather dust in your storage room. You won't even have any trouble operating it as you only need to plug it to the outlet for charging. When these ride on electric cars were first introduced to the market, they were undeniably expensive. However, as time progressed, more manufacturers have developed cheaper models which are more affordable for those parents on a budget. Nevertheless, expensive models are still around offering great quality and detail for those who can afford them. There are a lot of ride on electric cars available today. Choosing from all these models can be a tough decision to make. But your choice is made easier because these cars come in gender specific colors which can attract your child immediately. Aside from colors, the styles of the car can influence your kid's choice. There are ride on electric cars made to be sporty looking, others made to look classy, and those that have a rugged design. When choosing one for your child, bring him along so that he can decide for himself on the kind of car he likes.

    Investing in a piece of equipment like the CarCaddy electric car pushers increases productivity at the same time that it reduces the risk of damage and injury. This allows auto lots and mechanic shops to keep up with increases in volume, improve service levels and generate additional profits. Many vehicle manufacturers use a CarCaddy car and vehicle pusher to push the units short distances down a production line from station to station. A CarCaddy also has plenty of power to push a stalled vehicle at service centers or along highways. The primary benefit of using the CarCaddy electric car and vehicle pusher is to prevent the strains associated with pushing stalled cars, buses, heavy trucks, and other vehicles. Overextending the body when manually pushing cars from the parking lot into a service center garage can be extremely harmful to the worker, as can pushing a stalled vehicle from the highway to the shoulder. When a car and vehicle pusher is used for these routine tasks, damage to the body (including back and shoulder strain) is minimized, which keeps employees healthy and reduces workers’ compensation. The CarCaddy also prevents damages associated with moving these stalled vehicles using another vehicle. In cases where manpower is not available, other vehicles are used to bump up against the back end of the stalled vehicle. Both vehicles can be dented, scratched, or cracked due to this practice.
