Costs and environmental impacts of electric cars

This is a guest post by Joost van den Bulk in which the costs and benefits of electric cars available by 2010 are compared with internal combustion cars powered by gasoline for the Netherlands. It is a summary of his Master thesis in environmental science at Wageningen University in the Netherlands (PDF, 3 Mb, 72 pages).

Developments in battery technology have made cars driven by electric propulsion cost competitive with internal combustion based cars. Based on a scenario in which a car owner drives 15,000 kilometers annually, the car is owned for a period of 6 years, and the oil price on average remains above 100 dollars per barrel in the next two decades, it was found that an electric car for the consumer is already cheaper than a gasoline powered vehicle in the Netherlands, and that this will only improve in the future. This is the case because higher initial investments in the purchase of an electric car are more than compensated by lower fuel costs, reduced maintenance and tax benefits. Furthermore, greenhouse gas emissions of an electric car are at least half that of the gasoline powered car based on the current Dutch electricity mix.

NY Times Energy Series: Nuclear

The New York Times has been running a series of articles on the future of energy from a wide variety of perspectives and topics. Today's article focuses on the challenges of increasing the level of power generated from nuclear power plants.

My growing (and worrying) conclusion is that we are headed back to the future with coal - either liquified for our cars or simply burning it for electricity. Perhaps somewhat cleaner coal, but even clean coal is more polluting in terms of global warming than most other forms of energy production.

NY Times: NYC's Energy Future

This Sunday, the NY Times City section did an editorial on the Mayor's energy task force.

For a city that gobbles energy like contestants at the Coney Island hot dog eating contest, it was surprising to learn recently, from Mayor Michael Bloomberg's energy task force, that New York won't be needing new power plants until at least 2012. That's a very different report than one issued just two years ago, which said the city would be needing 25 percent more energy generation by 2008. The turnaround is a result, in part, of the city's aggressive conservation and efficiency goals under Mr. Bloomberg. But the city is hardly out of the woods on energy.

Indeed, while NYC is very energy efficient compared to it's suburban and exurban counterparts, the sheer number of people does require an enormous amount of power.
