Total emissions from EVs undercut ICE cars in 95% of the world

A new study claims that EVs are better for the environment than gasoline-powered vehicles in 95 percent of the world

 Comparing the eco-credentials of electric cars and their gasoline-powered counterparts isn’t as simple as counting the carbon emissions coming (or not) from the tailpipe. New research is claiming to have settled the debate once and for all by taking all factors into account, including the production of, and electricity generation for, EVs and found that they are better for the climate in 95 percent of the world.

While there is no debate that EVs pollute less once they are actually on the road, some argue that the CO2 generated during the manufacturing of EVs and in the generation of the electricity to charge them actually outweighs that produced by cars with internal combustion engines (ICEs). The thinking is that while renewables can play a part of the energy mix, EV owners still need to rely heavily on coal- and gas-fired power plants to keep their cars charged and running.

The new research was carried out by scientists at the University of Exeter, University of Cambridge and University of Nijmegen in the Netherlands, and found that while there are exceptions, electric vehicles are generally better for the climate in the vast majority of places.

Acclaimed Israeli astrophysicist suggests the sun drives Earth’s climate, not CO2

DD88F5AC-6284-4C5E-A699-724344ECE3FF

Nir Shaviv is an Israeli astrophysicist and chairman of Jerusalem’s Hebrew University’s physics department. He says that his research, and that of colleagues, suggests that rising CO2 levels play only a minor role in earth’s climate compared to the influence of the sun and cosmic radiation.

“Global warming clearly is a problem, though not in the catastrophic terms of Al Gore’s movies or environmental alarmists,” said Shaviv. “Climate change has existed forever and is unlikely to go away. But CO2 emissions don’t play the major role. Periodic solar activity does.”

But I thought that 97% of climate scientists agreed that human activity is the main driver of climate change?

“Only people who don’t understand science take the 97% statistic seriously,” said Shaviv. “Survey results depend on who you ask, who answers and how the questions are worded. In any case, science is not a democracy. Even if 100% of scientists believe something, one person with good evidence can still be right.”

Scientists have found an easy way to remove CO2 from air & reduce global warming

BB75442F-72A6-47AE-A770-05070C20AFD6

A number of research teams around the world are currently working towards scrubbing all the excess carbon dioxide from the air. It’s one of the prime reasons we are seeing record breaking rise in temperature across India this summer.

Not only could this do wonders to push back global warming, but we can also put all of that CO2 to good use in other applications.

This new Lithium battery tech can simply suck up CO2 to power itself

IMG_9285

We need this right now!

Everybody knows the world’s got a serious carbon dioxide problem, but an ingenious and potentially cost-effective way of dealing with our surplus CO2 could provide the means of tomorrow’s battery technology.

For years scientists have looked at ways of capturing carbon and storing it underground or even potentially in the ocean. But a new system might offer a powerful advantage over these efforts.

Canadian scientists are developing a system that could turn atmospheric CO2 into fuel

carbon-capturee_1024

An industrial carbon dioxide recycling plant is being developed by Canadian scientists that could one day suck CO2 out of the atmosphere and convert it into a zero-carbon e-diesel fuel. Developed by tech start-up Carbon Engineering and partly funded by Bill Gates, the system will essentially do the job of trees, but in places unable to host them, such as icy plains and deserts.

Earth’s Upper Atmosphere Suffers Record Breaking Collapse

NASA is puzzled over the record breaking atmopheric collapse

The Earth’s upper atmosphere has had a record breaking collapse, one that has scientists both puzzled and worried, NASA announced Thursday.

The collapse occurred during a period of low solar activity known as a “solar minimum.” During a solar minimum, sunspots and solar flare activity heavily diminish. Since the date range of a solar minimum expands over a 12-month period, it can take up to 6 months to identify one.

This collapse occurred during the 2008-2009 solar minimum. While these minimums are known to cool and contract the thermosphere, this collapse was 3-times greater than low solar activity could explain…

YeZ: Eco-Friendly Car that Acts Like a Plant

YeZ

What if there was an eco-friendly car that acted like a plant? It would take in CO2, and its exhaust would be oxygen. That’s exactly what the Shanghai Automotive Industry Corporation unveiled at the Shanghai Expo 2010 recently. The YeZ is a concept car designed to photosynthesize carbon dioxide from the air, much like a plant. The car is even designed to emphasize the idea of a eco-friendly through a plant-like process.

CO2 Recycler Creates Fuel From Carbon Dioxide

This prototype, known as the CR5, was designed to convert carbon dioxide into carbon monoxide, or water into hydrogen, using concentrated solar energy

Researchers at Sandia National Laboratories have built a machine that uses the sun’s energy to convert carbon dioxide waste from power plants into transportation fuels such as gasoline, diesel, and jet fuel. The system could provide an alternative to carbon sequestration; instead of permanently storing CO2 underground, the CO2 could be recycled and put to use.

Turning Seawater Into Jet Fuel

Faced with global warming and potential oil shortages, the US navy is experimenting with making jet fuel from seawater.

Navy chemists have processed seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel. But they will have to find a clean energy source to power the reactions if the end product is to be carbon neutral.
