Will the environment fall victim to the economy? 4

darryl-and-the-teslaMy friend Darryl who recently left his job as the SVP of marketing at Tesla Motors has been doing a lot of blogging in recent weeks, and I find myself strongly agreeing with much of what he says.  I’ve expressed many of the same ideas in my posts on AutoblogGreen and Autoblog, drawing a great deal of derision from some very earnest but in my opinion extremely naive readers.

I’m all for vastly more efficient and cleaner transportation for a number of reasons. I think burning fossil fuels is unsustainable from both an environmental and political/strategic perspective.  Unfortunately for every person who happily rides to work on their bicycle in 10 degree weather, there are hundreds whose focus is much more self-centered.  The reality is people buy the most car they can afford on the day they buy, without regard to future consequences.  In his latest blog post Darryl explains some of the economic theories behind all of this.

When gas is cheap they buy more powerful vehicles and only when fuel prices go up do they buy more efficient vehicles.  People have now become accustomed to better equipped cars and they expect a certain feature level for their dollar. If gas is cheap they will buy a thirstier better equipped vehicle over a more efficient model with fewer features.  The current economic climate will only make things far worse as increasing unemployment makes people reluctant to buy anything.

As much as people want electric vehicles to be mainstream, batteries are simply far too expensive and heavy to be widely used yet.  In light of this in order to make any progress on reducing fossil fuel use and carbon dioxide emissions, we need to take the most cost effective approaches as well as provide incentives and disincentives.

First up for disincentives we must let go of the idea of cheap gas forever.  Gas needs to taxed up to at least $4-5 per gallon. Since this will disproportionately affect lower income people the tax system needs adjustments to compensate. The upper cap on the incredibly regressive payroll taxes needs to be increased  and the first $10-15,000 needs to be exempted.  As long as gas is cheap increasing fuel economy mandates on manufacturers will only kill those companies because no one will want to buy the cars they are forced to build. We must created demand for efficiency through increased fuel prices. The idea of increased fuel taxes is finally gaining some steam at least online including over at Mark’s blog, although politicians still don’t seem too hot on the idea.

Because of the sluggish state of the general economy not much of anything is selling right now anyway. To compensate for that more positive incentives are needed to stimulate demand.  The extra revenue from the fuel tax could be used to fund rebates for more efficient vehicles as well as public transportation.

We also need to acknowledge the work being done by companies like Ford and Honda. A year ago Ford recognized that in order to make any real dent in fuel use and emissions it was critically important to find the most cost effective solutions. While electric vehicles reduce direct emissions to zero, there are still emissions from the power sources if coal or natural gas is the fuel.  The high cost also means that the numbers of such vehicles will remain for low for the foreseeable future meaning the overall effect on emissions will be negligible.

Ford developed turbocharged direct injection engines that they are labeling as EcoBoost. These engines reduce fuel consumption by 15-20 percent and Ford expects to be selling half a million of these engines annually within a couple of years. The extra cost will be far lower in the near term and have more overall impact in the near term while the cost and capacity of batteries is driven down.  Similarly Honda has developed a cost reduced version of its hybrid system for the new Insight that will debut next year.

Ford already has a full hybrid system in the Escape and Fusion, but those vehicles will only sell 50,000 units a year because of the cost.

Even efforts such as Honda’s hybrid and Ford’s EcoBoost won’t make a difference if no one can afford to buy. With the economy in the dumper, people will simply vote with their wallets and keep driving their existing vehicles and use the cheapest energy available. That means concerns about the environment will evaporate just as fast as SUV sales in the past year.

Green yule

It’s the 24th of December and the sun is shining. The last time we had any snow was a month ago and it didn’t stick around long. The temperature is about 41 degrees right now and at least it’s not raining for a change. At least we’re on the far side of the winter solstice and the days will be getting longer now.

A carbon question 2

I’ve been writing over on AutoBlogGreen for a couple of months now, so carbon emissions are on my mind a lot these days. As I was walking out of Target today I noticed a tank truck from NuCO2 filling up the carbon dioxide tank that they use in the snack bar and it triggered a question in my mind. Americans (and many others) drink huge amounts of carbonated soft drinks every day. Every single one of those bubbles from your drinks is comprised of carbon dioxide, considered to be the primary greenhouse gas causing global warming. Here’s my question. How much CO2 is emitted from every one of those soft drinks? It seems to me that all those drinks we open up every day, are emitting a hell of a lot of CO2 into the atmosphere, possibly more than cars. If you know the answer, please chime in!

Nuclear Power the solution to global warming? 2

I think not! One of the problems with nuclear power plants, is that they require some type medium to cool the reactor and keep the nuclear reaction under control. On the majority of reactors they use water flowing around the reactor to manage the temperature. Unfortunately water can only absorb a limited amount of heat energy. The amount of heat that can be absorbed is a function of the temperature difference between the water and the item to be cooled. The higher temperature, the less heat it can absorb at a given flow rate. Now that the heat transfer lesson is complete, here comes the problem. Nuclear plants are typically constructed near bodies of water like rivers and lakes. They draw in cold water, pass it around the reactor and eject the hot water.

Nuclear power has been proposed as a way to produce power without creating green house gases. The problem this week as Europe bakes in a heat wave similar to what we are seeing here, is that the temperature of rivers has risen so much that nuclear plants sitting on their banks can’t be cooled enough to operate. So as the demand for power for air conditioning reaches a peak, many of the power plants are shutting down because they can’t cool down enough to operate safely. So what do you do now? We need to use less energy!!
