So rather than just minimising emissions from driving, we are working to significantly reduce the carbon footprint of our production processes. The BMW Group already powers its production facilities worldwide entirely with green electricity today. The energy they supply is also used to manufacture a wide range of components for the two electric models, at BMW Group Plants Landshut, Dingolfing and Berlin. But as well as implementing more and more such contracts, the BMW Group is increasing the share of the renewable or carbon-neutral electricity it generates itself. The energy goals the BMW Group has set itself are designed for the longer term. Between and , emissions from production fell by more than 70 percent per car.

Tesla Motors has received more than , preorders for its hot new Model 3 electric car even though it will not be available for at least another year. That almost equals the , electric cars and plug-in hybrids now on American roads. Tesla has advertised its vehicles as having zero emissions, helping fuel the mania for the fun-driving sedan, but that's not necessarily true.
Low emissions, much less zero emissions, are only true in certain places where most of the electricity comes from a mix of low-carbon sources such as the sun, wind or nuclear reactors. Electric cars are great for eliminating oil from transportation, because very little U. But electric cars may or may not help the country combat climate change—and it all depends on where the electricity comes from.
Cars and trucks are responsible for roughly 24 percent of U. Because those emissions come from hundreds of millions of tailpipes, this source of pollution seems difficult to control.
Shifting it to hundreds of smokestacks at power plants that supply electricity to charge electric cars therefore seems like a more effective way to clean up the fleet. But those smokestacks, many attached to coal-fired power plants, are the single-largest source of greenhouse gas pollution in the U.
That source would grow as electric cars demand more and more electricity, unless tighter pollution controls are placed on power plants or electric utilities shift to less polluting sources such as solar. As it stands, a conventional Toyota Prius hybrid vehicle, which burns gasoline when its batteries are not engaged, and the all-electric Nissan Leaf produce roughly the same amount of greenhouse gas pollution: grams per mile, according to data from the U.
Department of Energy. That's an average across the U. In California, which has one of the highest proportions of clean electricity in the country, the electric vehicle would produce only grams per mile, half that of the hybrid.
Ditto for Texas and even Florida. But in the Midwest and South, where coal fuels the bulk of electricity generation, a hybrid produces less CO2 than an electric car.
In fossil fuel—dependent Minnesota an electric car would actually emit grams per mile of greenhouse gases. As a result, some researchers suggest that a regional approach to clean vehicle standards makes more sense than national standards that effectively require electric cars across the board. Minnesota could go for hybrids and California could go for electric vehicles. Nighttime is often when the wind blows but it is also when utilities like to run only their coal-fired power plants.
A recent study found that an electric car charged by utilities at night in the regional grid that stretches across Ohio, Delaware, Pennsylvania and Virginia creates more greenhouse gas pollution than if owners plugged in their vehicles at random times throughout the daytime, when the utility fuel mixes are more varied. The same argument applies worldwide. Driving an electric car in China, where coal is by far the largest power plant fuel, is a catastrophe for climate change.
And if the coal plant lacks pollution controls—or fails to turn them on—it can amplify the extent of smog, acid rain, lung-damaging microscopic soot and other ills that arise from burning fossil fuels. The same is true in other major coal-burning countries, such as Australia, India and South Africa.
The good news: the U. The changeover produces less CO2, making electric cars cleaner across the country, roughly equivalent to a hybrid.
On the other hand, the primary constituent of natural gas—methane—is itself a potent greenhouse gas. If methane leaks from the wells where it is produced, the pipelines that transport it or the power plants that burn it, the climate doesn't necessarily benefit. In short, electric cars are only as good as the electricity that charges them. In the absence of clean electricity, hybrid cars that can travel 50 or more miles on a gallon of gasoline produce the least emissions.
Electric cars still constitute less than 1 percent of U. So their environmental benefit—dubious for now, until more power plants get off coal—is not very worrisome.
The current shift back to SUVs that guzzle much more petroleum than other cars, prompted by low gasoline prices, is a more worrisome sign for future climate change. Perhaps by the time electric cars are ubiquitous, pollution from generating electricity will be zero. David Biello is a contributing editor at Scientific American.

Here are the 10 best power plants for cars and why we didn't call them engines
The vehicle transmission facility in Halewood, Merseyside, will be turned into an electric power unit production plant, the U. Ford stressed that the investment is subject to and includes U. Ford said it will start making the electric power units at Halewood in mid, adding that it plans to produce around , of them at the site each year. Last year, the U. It wants sales of new petrol and diesel cars to end in the U.

These are unprecedented times for us all—our company, our families and friends, our society, our nation and the entire world. The devastating COVID pandemic is transforming, perhaps irrevocably, the way we communicate, live and work. Refusing to discriminate between class and caste, region and religion, community or country, this invisible, lethal enemy has challenged us all in unforeseen myriad ways. Working from home for the first time has been a paradigm shift for many—that is certainly true for me personally. Adoption of technology is no longer a choice but an imperative to promote virtual collaboration. Becoming self-directed and independent and using the digital universe to achieve our goals is the urgency of our brave new corporate ethos. In this time of cataclysmic churn, I write this note to say how humbled I am by your deep commitment and work ethic.
Powered by water: BMW Group manufactures electric cars with regional green electricity
Coal fired power plants also known as coal fired power stations are facilities that burn coal to make steam in order to generate electricity. Coal plants require enormous amounts of coal. Shockingly: a MWe coal plant uses tonnes of coal per day, equivalent to an entire train load 90 cars with tonnes in each! If this train were to pass by your house at 40 kilometers per hour , it would take more than a day to pass! The conversion of this coal to the end goal of electricity is a multi-faceted process: .
The plant also captures heat produced in power generation and uses it to provide steam heat and chilled water to most campus facilities.

The truth is that its origin and its journey into your home to make life as we know it work is an enigma to many, despite how close we live with the energy. You put your finger on a switch, you press and things start to happen that, if you think about it seriously, seem like magic. Lights that illuminate everything around you, a warmth you need to cook and keep your home warm.
Before a Nuclear Power Plant Emergency. The following are things you can do to protect yourself, your family and your property from the effects.
The rise of renewables is good for the planet. Converting renewable electricity into storable fuels spreads the benefit of carbon-neutral energy across sectors. The power-to-X process allows for just that. It is a transformation technology that converts electricity into carbon-neutral synthetic fuels, which can then be used in other sectors or be stored until needed.RELATED VIDEO: We Can Power The World With Algae!
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel , an energy other than traditional petroleum fuels petrol or Diesel fuel ; the term also refers to any technology of powering an engine that does not involve solely petroleum e. Because of a combination of factors, such as environmental concerns, high oil-prices and the potential for peak oil , development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world. An environmental analysis of the impacts of various vehicle-fuels extends beyond just operating efficiency and emissions, especially if a technology comes into wide use. A life-cycle assessment of a vehicle involves production and post-use considerations.
