Elon Musk says he's increasingly confident that a massive factory will lower battery costs enough for a mass-market electric vehicle.
Subtracting nuclear reactors in the U.S. could make it tougher to meet climate goals.
We should think sensibly about nuclear energy’s risks.
The energy-efficient power networks of the future will require entirely new ways of forecasting demand on the scale of individual households. That won't be easy.
The difficulty of predicting local effects of climate change makes a compelling case for preventing it.
Titanium sheets and additional aluminum deflect or block road debris, better protecting the lithium ion battery in the Model S.
When it comes to cities, being big and rich is better for the planet than being big and poor, according to a new study of carbon dioxide emissions from cities around the world. But is this correct?
Engineers have built a powerful microscopic engine that relies on the combustion of hydrogen and oxygen. One problem: nobody knows how it works.
A factory that takes in raw materials and produces finished battery packs could lower costs for the most expensive part of an EV.
If electric cars become popular quickly, the demand for charging them is likely to exceed supply. Now mathematicians have worked out how electricity companies can distribute their power fairly to car owners. But the price--accurate information about driving habits--may be too much to ask.
