A friend just asked me what I think of the Tesla Supercharger stations.

I think it’s a good concept overall, from the standpoint of the EV adoption curve, though this is a bit misleading.  In the middle of a sunny day, i.e., under perfect conditions, I estimate that it would take 5 – 6 hours for the PV array shown there to charge ONE Tesla-S.  I.e., implying that they are charging those cars purely with solar energy is disingenuous.

Making electric transportation work ecologically requires charging without increasing the amount of coal that’s burned, and that’s not an easy feat.  We’ll get there, but we’re not there now.

I know I harbor a great deal of pessimism/cynicism about the corruption that has engulfed our political process.  But I have to say the Move To Amend people have really kicked some major butt, to use a not-too-scholarly term, in the effort to pass a constitutional amendment to overturn the U.S. Supreme Court’s Citizens United vs. Federal Election Commission ruling and declare that only human beings – not corporations – are entitled to constitutional rights and that money is not speech and campaign spending can be regulated.

In fact, the country voted overwhelmingly in favor of this concept in yesterday’s elections.  From their newsletter: 

Residents in over 100 cities had the opportunity to vote on measures calling for an end to the doctrines of corporate constitutional rights and money as free speech, and in every single town the vote was supportive. Often by an overwhelming margin. In Eau Claire, WI the vote was 71% in favor of a measure stating, “Should the US Constitution be amended to establish that regulating political contributions and spending is not equivalent to limiting freedom of speech, by stating that only human beings, not corporations, unions, or PACs, are entitled to constitutional rights?”

I have spoken with Move To Amend spokesperson David Cobb a couple of times, including a 30-minute interview for my Clean Energy Radio show.  The man’s a human firecracker.  Keep up the good work!

My posts wind up (somehow) on Cleantechies Blog, where David Repka saw my article: In Renewable Energy, Things May Not Be What They Seem and commented:

The greatest point of frustration is the lack of certainty and clear, coordinated, cohesive, long-term direction in every step in the process: permitting, interconnections, planning, zoning, regulatory, environmental, taxation, etc. Every state having their own RPS (renewable portfolio standard) and tax code of incentives is maddening. There needs to be a cohesive, national energy policy with an FIT (feed-in tariff).

This is exactly right.  The fossil fuel industry is doing everything in its power (which is considerable, to say the least) to make sure that the development of clean energy is slow, uncertain, and as frustrating and unprofitable as possible.  We all know that we need a national energy policy, but we’re a million miles from it.  This is precisely why ex-Pennsylvania governor Ed Rendell said what he did. i.e., don’t expect this to happen inside the Beltway, because the money from the oil companies driving the political process never stops. 

I’m sure hoping that Obama makes a liar out of me and does something honest and decent on this in his second term, but I’m not counting on it.

Those of us trying to make sense of the validity of renewables versus fossil fuels are forced to deal with many different parameters.  For instance, we often talk about the externalities of coal, i.e., the cost factors that are not captured in the transaction between the utility and its customer, but passed on to society at large.  We note the build-up of mercury, ocean acidification, and greenhouse gas released into our atmosphere, etc.  Of course, there are issues with solar and wind as well, all of which need to be factored in.

Here’s an article on one kind of externality that my not receive as much attention as it’s due: the use of water in generating electricity.  Certainly this is something to be examined, as potable water becomes scarcer and thus more valuable.

One of the business plans I support is a breakthrough in wind turbine construction, essentially rooted on getting the same production as today’s design, while using significantly less materials, thus cutting costs substantially.   But in my quest to help them raise the investment capital they need to move forward, I’m running into investors who are unsure of the demand, given the end of the production tax credit in the U.S.

In reply to an email yesterday, I explain why I remain bullish: (more…)

One of the many consequences of climate change and the run-off of our increasingly powerful chemical fertilizers is the killing of our oceans. In this article, a team of researchers reveals how more ocean habitat is lost each year, as the amount of dissolved oxygen is reduced below levels that support life for pelagic fishes, i.e., those that do not live on or near the shores, reefs, or sea bottoms.

The solution?  There are many, of course.  One that we explored in a webinar last April is aeroponics, growing plants in a recirculating mixture of water, air, and minerals.

It’s Election Day in the United States, much anticipated here for several reasons, perhaps chiefly insofar as it means an immediate cessation of the horrifically mean-spirited and misleading campaign advertising. 

I just got back from the polling place and found this email from Ralph Avallone, who serves as president of the National Green Energy Council, a non-profit green energy advocacy group.  Their main push is job creation in the green energy sector, certainly a laudable goal.  Avallone concludes:

Please get out and vote today…The future of our nation as an economic superpower depends on it.

Absolutely true.  I would only add: Vote in such a way as to maximize the probability that we will soon have a progressive energy policy that both: a) puts millions of people back to work and b) addresses the many different kinds of catastrophes associated with a “business as usual” approach to the subject.

I don’t know how many readers are in the Sierra Club’s email database.  If you are, you just saw this come across the wire:

Tuesday will be the single most decisive day for America’s environment for years — perhaps ever.

Who will win tomorrow: Champions for our climate, clean air and water, clean-energy jobs, and wildlife? Or Big Oil, Big Coal, and the politicians they keep in their pocket?

Obviously, this is something of an oversimplification. (more…)

I just got back from a fairly vigorous seven-mile hike my 2GreenEnergy financial adviser.  This time we did Gaviota Peak, absolutely stunning, overlooking the deep blue Pacific.  The hike had about 2200 feet of altitude gain, which may not impress you gazelles in Colorado – or Nepal — but it got my attention.

I took the opportunity to promote what we’re doing here, albeit in a very low-key way.  In a canister at the peak is a book with a pen, in which people write their thoughts, such that others may come along and take inspiration.  I jotted down a few notes and invited folks to check out 2GreenEnergy.com.  Of course, if a single person does that, it will be a minor miracle, but as we’ve all heard a thousand times, it’s the thought that counts.

Frequent commenter Steven Andrews writes:

Wind and solar have the best characteristics plus on top of that use no water resources.  Why are these systems so under attack by fossil fuel burners?  Gandhi said: first they don´t pay attention, then they deny, then… they attack, lastly, we win.  Wind and solar don´t consume oil, gas or coal, they don´t leave toxic chemicals, or radioactive materials behind, so they are cheaper and better.

Better, yes — in several senses; cheaper, no.  (more…)
