Plug-in Hybrids: Renewable Energy Solution of the Month
July 14th, 2010
Support Climate Denial Crock of the Week – go to www.greenmanstudio.com This video inaugurates a new series, that will augment, but not replace, “Climate Denial Crock of the Week”. Many people seem to think dealing with climate change will bring poverty and limit human development. The truth may be exactly the opposite. Moving to a world of where we aren’t fighting each other over the last few drops of oil, where energy is free, will mean a better life, with greater opportunities even for an expanding population. If we make the right decisions, we could be on the verge of the most prosperous period in human history. Climate Denial Crocks will be back soon to tweak trolls and ding deniers. http www.environmentamerica.org www.udel.edu www.udel.edu newenergynews.blogspot.com climateprogress.org

this is incorrect. The efficiency of electric cars is so much greater than gasoline powered, that even when charging them with coal power, they are a better choice emissions wise.
I love the idea of a feedback system between the car battery and the national grid.
If instead of a petroleum-electric hybrid, a hydrogen-electric hybrid was developed then that would be perfect. Giving emissionless unlimited range and freedom while keeping the home plug-in system so the car can act as a generator. I think this is possible because the Honda hydrogen car uses a fuel cell to charge a battery which then powers the motor of the car. So just plug that battery into the mains.

@mwtbell32
Honda’s car is cool, but still pretty expensive.
The gas-electric hybrids will be first to market. anybody’s guess as to what the
final winning technology will be, but breakthroughs in battery tech give an edge to all electric vehicles.
Very interesting video. Keep up the good work
in the future 50% of cars will be electric, the rest will be powered by the tears of oil executives
Hi Greenman, I have one doubt. Is there a recycling process available for electric cars baterries?
@alessandramarcarian
Yes, there is already an aftermarket developing for Li-on batteries, as they still work for storage even after their “useful” life as car batteries is over.
As we move forward, more advanced designs using cheaper, more widely available materials are already coming out of labs, that will make it even easier in the future.
SUUUUUUUPAAAAAA CAAAAAAR
The Chinese would be better off burning gasoline as far as co2 is concerned. Despite their electric power plants being all new, they use old technology 40% less efficient than current technology! All these cars do is move the co2 from the tailpipe to the coal fired power plant.
thanks for yr wise words Greenman!
Better is better!!!
@alessandramarcarian
You can indeed recycle Li-ion batteries. Right now it’s generally not done because the supplies of fresh material are too cheap to bother. Also, most of the components (the lithum, iron, and phosphate if it’s LiFePO4 for instance) are basically non-toxic.
@rusty1491
There’s about 32 MJ of energy in a (US) gallon of gasoline. That’s about 8.9 kWh. But there is a big problem: burning it in a typical Otto-cycle (gasoline) engine, using that to power wheels, you lose over 80% of it. So you get 1.75 kWh of propulsion.
.
By contrast, the “heat rate” of a modern combined-cycle gas turbine plant is under 7000, making it about 50% efficient. Add in losses in electric cars and you get approximately 40% efficiency: twice as good.
@silatube — oops, that’s 32 MJ/liter, not /gallon. The efficiency numbers are correct though.
Don’t forget to vote for Greenman in the Brigher Planet contest.

@christo930 Electric cars are more than 80% efficient in converting its energy while gasoline cars’ efficiency less than 15%. So even if the electric power plant is 40% less efficient it still makes plenty of sense to switch to electric car.
@tantpwei Their power plants are up to 40% less efficient than our latest plants. Batteries are terribly inefficient (takes 1.6 watts to charge 1 watt). They are also far dirtier. Coal fired power plants produce all kinds of nasty stuff besides co2. Believe me, right now the Chinese are better off with diesel fuel cars.
this is all fascinating, but I have one question. I live in an apartment in the projects, I and hundreds of neighbors don’t have a garage, we all simply park on the street. I’m certain that this situation is true for millions of city dwellers throughout the world. If we were to get plug in hybrids, where exactly would we plug them in? I think we’re going to need to commit to at least one more change in infrastructure so we can all have outlets available.
@wakeangel2001
When apartment buildings and housing projects figure out that charging stations plus electric vehicles produce revenue, you will see them become available. There are a number of initiatives in several states to set up charging stations.
I see, compared to the potential revenue the grid could gain the investment of setting up charging stations around the block (which could be as simple as a weather protected outlet sticking out of the ground) is a minor cost.
amazing video! this explains a lot of my questions about electric cars! Thanks
Why feed the energy from the car battery to your grid? Why not just directly power your house with it? Only surplus goes into the grid.
Thanks for some possitive news!! even if it may not all happen it is good to hear.
(CNN) — A highway-worthy airplane moves one step closer to production with a recent weight exemption approved by the Federal Aviation Administration.
The Transition Roadable Aircraft, developed by Massachusetts-based engineering firm (…)
Transition is designed for trips of up to about 450 miles and can travel about 100 miles per hour in the air and “highway speeds” on the ground (…)
the Transition will cost $194,000. The first delivery will occur in about 18 months (…)
Supercar!
@wakeangel2001 They would not only be charging stations, but would be grid feed stations (in the case where electric cars had solar cells on the roof), so that there is a benefit to the grid which gets more power to meet peak demands, as well as a benefit to the car owner/user who gets to recharge their car. Assuming sunlight, and assuming tough solar cells on car roofs (we recently had a hail storm here that has left a lot of cars on the road looking like golf balls).
