Renewable energy & electric transport....
Today's post: Wednesday, 8-12-2009
We need an 80% reduction in fossil fuel use by 2050 to avoid the worst global warming effects. And, practically speaking, we need to also double our electricity generation and double the useful work done per unit of electricity & other energy sources as well during that same time to have a decent economy.
At some point, the oil that we’ve been using to power much of our economy will begin to run low enough that our world economy will shrink due to lack of supply or excessive costs or both.
Electricity generated by solar or wind power or by using heat from geothermal energy to generate electricity AND electricity generated by nuclear power all avoid releasing CO2 and using oil.
(If coal to generate electricity can be burned in a way that allows the CO2 to be sequestered or converted to biofuel that also would replace oil and allow for more electric transport. Very soon electricity generated from coal and nuclear will cost more than from solar and wind. But now it may cost slightly less; and clean coal and nuclear will need less new transmission lines as they are or can be located next to existing transmission lines.)
That puts a very high premium on electric and/or plug-in hybrid cars and trucks and on electrically powered mass transit and trains.
And to build such cars and trucks and to allow electricity needed but not currently being generated by wind or solar or to allow excess electricity generated by wind or solar at other times to be stored all require reliable, fast charging, batteries that tend not to wear out or to require replacement only after extended use.
Also, for transport, having light and compact batteries is very important.
From large companies such as SONY to smaller startups such as Tesla and Imara Corporation in the Silicon Valley and in other parts of the world, many companies are working on such improved battery technology. (Mobile electronic devices share similar battery needs with the battery needs of electric transport. So battery advances for either use may well be used by the other use as well.) We may also see the use of combinations of capacitors that can be very rapidly charged and discharged with relatively faster discharging and charging batteries that are changed more often with batteries that discharge and charge more slowly but last far longer.
In addition, the electricity for this transport will begin to need more electricity generation which increases the need for a massive increase in solar and wind and new smart grid transmission lines to connect these new sources to users. In the earlier stages this need will fortunately be less acute since car batteries in electric cars and plug in hybrids can be charged at hours of the day other uses tend to be at their lowest so existing generation capacity can be used.
Tesla, with its good looking model S all electric sedan and GM with its plug in hybrid Volt are pioneering this market. But in the same way most car companies now make hybrid cars, soon most car companies will make all electric cars or plug-in hybrids or both.
So, it looks like the market for batteries to go in these cars looks like it will be very, very big within 2 to 5 years and then grow even more.

Good news & bad on renewable energy….
Today’s post: Weds, 3-5-2008
There have been several really positive news stories lately.
Some time ago the large Silicon Valley technology company, Applied Materials bought a thin film solar company. Since then they have been quietly growing a quite large volume of sales in solar. They are large enough that this has become a quite substantial business already.
Now it’s just been announced that they have signed a deal, apparently with a company in China to build enough solar electricity generation –IN THIS ONE DEAL –that by itself it will increase current world-wide solar electricity generation by about 1/12th or 8 % above its current levels. They are using large arrays of large format, “garage door” sized, thin film panels in a solar energy farm to do this.
This is great news for three reasons. It shows we are beginning to get large scale increases of electricity generated from solar sources. The announcement said that they already are able to do this for about what a fossil fuel plant can do per kilowatt generated costwise. And, by simply continuing to build more capacity, the economy of scale alone will allow them to soon cut costs by another 15 to 20 %. That will make solar cost LESS than fossil fuels for generating electricity. Third, if this solar energy farm is located IN China, it will likely replace a new coal burning plant that otherwise would have been built to generate this electricity.
Secondly, it has been announced that both General Motors & Daimler will begin making & selling hybrid cars using lithium ion batteries.
That’s also very good news for several reasons. It means the energy efficiency of the fleets of cars these two large companies make & sell will begin improving sharply over time. And, as they & other companies perfect using lithium ion batteries, all electric cars like the Tesla cars & plug-in hybrids will increasingly be common & used widely.
Lithium ion batteries are so much lighter & more compact than batteries using heavier metals this is now looking more & more likely. Further, it suggests GM now expects it to MAKE THEM MONEY to make more energy efficient cars. And, if they once manage to do that, all major car manufacturers will do so as well.
Combining these two stories strongly suggests that within 20 years we will increasingly be able to use solar generated electricity to power our cars & SUV’s – or at least provide the majority of their energy needs with solar generated electricity.
These are very large players. So these stories are extremely good news.
The bad news is that not ONE of the three major candidates for President of the United States has yet begun to run as their most important campaign issue that they are the best candidate to lead the conversion of the economy of the United States & the world to run on renewable energy.
We are already about 20 to 40 years late in doing this to avoid serious economic problems from global warming & are within just a few years of the deadline to avoid great depression levels of economic disaster caused by global warming.
Secondly, oil prices have more than tripled in just the past few years. The resulting increase in gasoline prices this has caused have begun to exert a strong braking effect on disposable consumer spending. If increased world wide demand continues to rise faster than new supplies are developed – which looks likely – gasoline prices could easily triple again in 10 years. That won’t be kind to our economy or to people holding on to their jobs. And, this is a very real near-term problem.
Third, the money spent by the United States, Western Europe, Japan, & China on imported oil is directly & indirectly funding terrorists from the countries that have oil to export. This is a very dangerous situation that threatens our national security.
To avoid really harsh economic problems & slow global warming we must have as our next President a leader who will lead an extraordinary, focused effort by virtually every able person in the United States to switch our economy to one powered by renewable energy that we are increasingly efficient at using.
The comparison to the Manhattan Project is apt for this. But it really needs even more than that. It will require an effort comparable to all of what the United States did to win World War II.
John McCain clearly values national security. And, as a Republican, he likely wants to keep our economy & the businesses that make it up strong.
Barack Obama has written in his Audacity of Hope book statements that suggest he knows something about this issue; & most of his stated policy on energy listed on his campaign website is reasonably good. And, he clearly has inspirational leadership ability.
Hillary Clinton has said nothing to suggest she is against renewable energy. And, while Bill Clinton was our President, he did more to advance energy efficiency & renewable energy than is generally known.
But, so far not ONE of them has made this issue the main theme of their campaign.
Gentlemen, Lady, the handwriting is on the wall & has been for quite some time.
It’s the energy economy stupid!
I think the first of the 3 candidates who notices that & runs as the best person to lead us in that area -- & who explains how our economy, our jobs, & our way of life depend on us making this change, will be our next President.
Anything any of you reading this can do to get this to them or the people running their campaigns would be much appreciated.
