IEA report calls for no investment in new fossil fuel supply and end to sales of ICE cars by 2035

Green Car Congress

In the near term, the report describes a net-zero pathway that requires the immediate and massive deployment of all available clean and efficient energy technologies, combined with a major global push to accelerate innovation. The pathway calls for annual additions of solar PV to reach 630 GW by 2030, and those of wind power to reach 390 GW.

How to improve EV traction motor efficiency

Charged EVs

For example, torque is proportional to magnetic flux intensity, which itself is proportional to the product of current and the number of turns in each armature winding, so doubling the number of turns cuts the required current to produce the same torque in half. Resistive losses aren’t just a problem at high torque (i.e.
