Self-driving smart #cars might be stealing the limelight but industry experts think their impact will be insignificant compared to electric vehicles (EVs). Revolutionary advances in battery technology will allow vehicles of all shapes and sizes to travel long distances powered not by polluting fossil fuels but electricity; reducing both the threat to mankind’s health and the impact on the environment.The concept of the electric car has been around for decades but early examples were cumbersome, inefficient and expensive. Recent advances have facilitated the creation of attractive models, such as the #tesla, and have sparked hopes of an industrial renaissance. Investors, financiers, producers and the general public alike are all watching the EV industry with cautious optimism.The numbers (...)

When Will Electric Cars Go Mainstream? It May Be Sooner Than You Think - The New York Times

As the world’s automakers place larger bets on electric vehicle technology, many industry analysts are debating a key question: How quickly can plug-in cars become mainstream?

The conventional view holds that electric cars will remain a niche product for many years, plagued by high sticker prices and heavily dependent on government subsidies.

But a growing number of analysts now argue that this pessimism is becoming outdated. A new report from Bloomberg New Energy Finance, a research group, suggests that the price of plug-in cars is falling much faster than expected, spurred by cheaper batteries and aggressive policies promoting zero-emission vehicles in China and Europe.

Many owners charge their cars overnight in their garages, but that is much harder for people living in cities who park their cars on the street.

As a result, the Bloomberg report warns that plug-in vehicles may have a difficult time making inroads in dense urban areas and that infrastructure bottlenecks may slow the growth of electric vehicles after 2040.

Even with a sharp rise in electric vehicles, the world would still have more traditional petroleum-powered passenger vehicles on the road in 2040 than it does today, and it will take many years to retire existing fleets. And other modes of transportation, like heavy-duty trucking and aviation, will remain stubbornly difficult to electrify without drastic advances in battery technology.

Battery offers new hope to renewables | Climate News Network

▻http://www.climatenewsnetwork.net/2014/01/battery-offers-new-hope-to-renewables

It sounds like a seminal step towards unlocking the potential of renewables – a research team has high hopes it has found a cheap and effective way of storing huge amounts of energy.

LONDON, 10 January – Scientists in the US think they may be on the track of a new kind of battery technology that could store huge reserves of energy.

One of the great problems of renewable energy generators such as photovoltaic cells and wind turbines is that they can’t respond to demand.

When the sun is out, nobody needs so much heating and lighting, so the electricity goes to waste. In theory, surplus energy could be saved for hours of darkness or when the winds drop, but at a prohibitive cost. But Michael Aziz of Harvard University in Boston and colleagues report in Nature that they have tested what is, quite literally, a solution to the problem.
