CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. That’s why the shift away from coal is so important for EVs. Jeremy Michalek.

Lessons from a year with solar power

EV Info

It was one year ago that we decided to add solar panels to our roof. The standard unit of electrical power is the watt, which is defined as a current of one ampere, at a voltage of one volt. More simply, volts x amps = watts. In the UK, the standard wall socket delivers 240 volts. Panels: JA Solar black.

GM reduced energy intensity and carbon intensity per vehicle in 2013

Green Car Congress

One of the challenges we face is that our 2020 renewable energy goal was based on doubling solar capacity by 2015. Complexity of solar purchase power agreements and the cost competitiveness of solar energy in various regions of the world are impacting the pace at which we can add solar capacity. Renewable energy.

Zero Emission Solar Charging At Chevrolet Volt Plant [Video]

All Cars Electric

Coal power?" We've discussed before the issue of how clean electric cars really are when you take into consideration the source of the electricity you use to charge them - they're only as clean as the grid powering them. It's usually one of the first things EV dissenters bring up. Yeah, but where does the electricity come from, hmm?

How to Hasten India’s Transition Away From Coal

Cars That Think

Greenhouse gas emissions will certainly grow too, because India’s energy generation is dominated by fossil fuels—coal-fired power plants for electricity, coal- and gas-fired furnaces for industrial heating, liquid petroleum gas for cooking, and gasoline and diesel for transportation. percent from solar and wind power.

Lean Software, Power Electronics, and the Return of Optical Storage

Cars That Think

It’s very similar to the infrastructure for electric cars because the idea, ultimately, for electric cars is that you also are revamping your grid to facilitate, whatchamacallit, intermittent renewable energy sources, like wind and solar, because having an electric car that runs off a coal-fired power plant is defeating the purpose, essentially.
