The Koch Brothers and their fossil fuel industry allies are waging a major campaign to rebrand oil and gas as "innovative" and "sustainable" solutions, and to limit consumer choice by attacking clean energy and electric vehicles (EVs).
Investigative journalist Peter Stone revealed their plans to spend about $10 million dollars per year to boost petroleum-based transportation fuels and attack government subsidies for electric vehicles.

(1,091 posts)The hybrid comes out of the stop cycle using the electric drive then the IC engine starts after you get in motion - very smooth transition. I also like that a part of the braking function is used to charge the battery - thus extending the life of your brake pads.
My other car with stop/start you have to wait for the engine to get up to power before moving.

Could existing electric vehicles (EVs), despite their limited driving range, bring about a meaningful reduction in the greenhouse-gas emissions that are causing global climate change? Researchers at MIT have just completed the most comprehensive study yet to address this hotly debated question, and have reached a clear conclusion: Yes, they can.
The study, which found that a wholesale replacement of conventional vehicles with electric ones is possible today and could play a significant role in meeting climate change mitigation goals, was published today in the journal Nature Energy by Jessika Trancik, the Atlantic Richfield Career Development Associate Professor in Energy Studies at MIT's Institute for Data, Systems, and Society (IDSS), along with graduate student Zachary Needell, postdoc James McNerney, and recent graduate Michael Chang SM '15.
"Roughly 90 percent of the personal vehicles on the road daily could be replaced by a low-cost electric vehicle available on the market today, even if the cars can only charge overnight," Trancik says, "which would more than meet near-term U.S. climate targets for personal vehicle travel." Overall, when accounting for the emissions today from the power plants that provide the electricity, this would lead to an approximately 30 percent reduction in emissions from transportation. Deeper emissions cuts would be realized if power plants decarbonize over time.
The team spent four years on the project, which included developing a way of integrating two huge datasets: one highly detailed set of second-by-second driving behavior based on GPS data, and another broader, more comprehensive set of national data based on travel surveys. Together, the two datasets encompass millions of trips made by drivers all around the country.
The detailed GPS data was collected by state agencies in Texas, Georgia, and California, using special data loggers installed in cars to assess statewide driving patterns. The more comprehensive, but less detailed, nationwide data came from a national household transportation survey, which studied households across the country to learn about how and where people actually do their driving. The researchers needed to understand "the distances and timing of trips, the different driving behaviors, and the ambient weather conditions," Needell says.
By working out formulas to integrate the different sets of information...
