The Dirtiest Corvette Ever

  The Dirtiest Corvette Ever Corvettes are dirty cars.

A new study has tried to address two of the main concerns over the environmental impact of electric vehicles versus gas- powered cars : namely the emissions from electricity generation to power the EVs and the impact of mining raw materials. The main takeaway is that even electric cars powered

Using coal powered electricity electric cars do nothing to cut emissions, using natural gas electricity they’re like a top hybrid and using low carbon power they result As you can see, even after vehicle manufacturing is included the carbon intensity of driving an electric car varies 5 fold based on the juice.

Regardless of how dirty the energy source, any battery-powered car is still cleaner than diesel.

Opposition to the electric-car revolution has long argued that if one accounts for the well-to-wheel impact—the pollution produced from the entire cycle of power generation to fuel a car, rather than just the gasoline to power it—battery-powered vehicles are not necessarily any cleaner than gas-powered ones because of the dirty ways we produce electricity.

BMW’s and Canada’s electric-vehicle future

  BMW’s and Canada’s electric-vehicle future The transition to electrified vehicles is under way and BMW is ahead of the curveIf these regulations are successful, other governments will follow their example and automakers will have to be ready.

A lifecycle analysis from VUB University (Brussels) and Transport & Environment (T&E) has concluded that, even when powered exclusively by the most carbon intensive electricity in the world, plug-in electric cars still have a smaller greenhouse gas footprint than their diesel counterparts.

Even when they are powered exclusively by the “ dirtiest ” grid-provided electricity in the world, plug-in electric vehicles are responsible for a smaller greenhouse gas footprint than diesel cars are , according to a new lifecycle analysis from VUB University (Brussels) and Transport & Environment

A new study (pdf) from VUB University in Brussels looked at a number of different European countries and found that, in the case of diesel cars, electric cars are always better, no matter where the energy comes from. Take Poland, for instance. According to the International Energy Alliance, Poland still received 50% of its total energy production from coal, the dirtiest of all energy sources, in 2016, meaning that the way that power was generated to power that Tesla or Nissan Leaf was not the cleanest.

Still, the study shows that a battery-powered vehicle in Poland, well-to-wheel, emits 25% less carbon dioxide over its lifetime than a diesel car.

This is of particular importance in Europe where, in an effort to meet Kyoto protocol goals, Europeans turned to diesel because, though it produces more smog-causing particulate matter, diesel is actually slightly better than unleaded gas terms of its production of carbon dioxide; in 2014, more than 50% of European cars ran off diesel.

EVs Are Cheap to Run but Expensive to Own, Thanks to Abysmal Resale Values

  EVs Are Cheap to Run but Expensive to Own, Thanks to Abysmal Resale Values <p>If you’re planning to buy a new electric car, you’d better be prepared for some sticker shock—not when you buy the car, but when you sell it.</p>Electric cars are more efficient than gasoline or diesel vehicles, and they save serious money—a few hundred to a few thousand dollars a year, depending on the vehicle type—using electricity from the grid versus fuel from the gas station. They cost less to maintain and repair, too. But all that money saved—even including the $7500 federal EV tax credit that will sweeten your first year—won’t counter the worst thing to befall most EVs: horrendous depreciation.

When it was negative, the electric car was dirtier and instead should be taxed. Dallas (,144) and Houston (,140) also fared well. Still , even in Los Angeles, where the environmental Assuming electricity grids will get cleaner , moving away from gasoline cars is the only way to approach a

3. No Emissions: Electric cars are 100 percent eco-friendly as they run on electrically powered engines. It does not emit toxic gases or smoke in the environment as it runs on clean energy source. They are even better than hybrid cars as hybrids running on gas produce emissions.

In the US, where the majority of consumer cars run on unleaded gas (pdf), electric cars can win out, too. A study by the Union of Concerned Scientists earlier this year found that well-to-wheel, “for over 70% of Americans, driving an [electric vehicle] results in fewer emissions than even a 50mpg gasoline vehicle.”

And as the cost of renewable energy continues to decline worldwide, resulting in cleaner energy sources, and advances in battery technology makes energy storage more efficient, lighter, and energy dense, the environmental advantages of electric over gas-powered cars will only become more pronounced.

That said, for the moment, in countries like India, China, and even Australia–where coal is still the predominant energy source—the demands placed on the electricity grid from the production, then charging of electric vehicles may actually be worse than a hybrid or even a highly efficient gasoline car, Scientific American reported.
