The New York Times on Sunday reported about Solar World‘s new solar panel plant in Oregon. The Germany company is making a big ($300 million) bet that the United States is the place to be if you are a solar panel manufacturer.

The message for solar companies, Mr. Pichel says, is “get your butt over to the U.S. if you want to participate and get some of that stimulus package money.”

Solar photovoltaics still account for less than 1% of the electricity generated in the U.S. today. However, the article reports that in various markets, including California, the number of solar panels installed is doubling every year. At that kind of growth – even if it slows down slightly due to the current recession and credit crunch – in five to ten years solar electricity could account for a much more significant share of the electricity supply.

I’ve been focused lately in the blog on energy efficiency, and not so much on alternative energy sources, so it’s good to see that there’s still a lot of momentum going on there!

Biofuels Are Sustainable and Economical, Say German Researchers

Oh Snap! Now some German scientists have (in effect) taken a swing at Stanford professor Mark Z. Jacobson, who concluded in a recent paper that biofuels are a bad policy direction (see summary post here).

In their paper Sustainable global energy supply based on lignocellulosic biomass from afforestation of degraded areas, Prof. Jürgen O. Metzger from Carl von Ossietzky University of Oldenburg in Germany and Prof. Aloys Huettermann from the University of Goettingen in Germany say that growing and using biofuels for all the earth’s energy needs is not only possible without jeopardizing the global food supply, but also economically feasible.

Their key discovery is that by reforesting land that has been “degraded by human use in historical times”, they found:

… the global energy demand projected by the International Energy Agency in the Reference Scenario for the year 2030 could be provided sustainably and economically primarily from lignocellulosic biomass grown on areas which have been degraded by human activities in historical times.

Deutsche Bank Confirms Green Energy Creates Jobs and Economic Growth

From MIT’s Technology Review comes this column from Kevin Bullis, about a recent report from Deutsche Bank on the economic benefits of investing in new energy projects:

It argues that it’s possible to address challenges related to climate change, energy security, and the financial crisis at the same time by investing in four specific areas: energy-efficient buildings, electric power grids, renewable power, and public transportation. The report cites figures that suggest investing in these areas creates more jobs than investing in conventional energy sources because much of the old energy infrastructure is already in place. It says that “a $100 billion investment in energy and efficiency would result in 2 million new jobs, whereas a similar investment in old energy [such as coal or natural gas] would only create around 540,000 jobs.”

Of course, Obama has already pledged to do something along these lines, and the blogosphere (including me, here) has chimed in as well. But the imprimatur of Deutsche Bank adds some gravitas to the proposal.

Great Summary Of The Green Goodness Of The Bailout

Image via Wikipedia

In this post, the ecopreneur details the silver lining of the hurricane cloud that is the bailout bill.

No news was bigger than the $18 billion package for renewable energy that was slipped into the $700 billion Wall Street financial bailout (H.R. 1424, the Emergency Economic Stabilization Act of 2008)

In particular, the future of a number of large projects was contingent on the renewal of the investment tax credit, such as the PG&E 550MW solar farm. Now, with the ITC safe for eight years, those projects can go ahead.

What are your feelings about the bailout and its effects on the solution to the climate crisis and energy security? Let me know your thoughts in the comments.

Top Green Energy Stories For August 2008

Top Fivewoodleywonderworks
Top Five Stories

August was a great month for energy storage breakthroughs! In addition, a big talking head talks big, and a business-of-green-energy announcement make my list of top stories.

1. Hydrogen from water
2. Fuel cell breakthrough #1: cheap catalyst
3. Fuel cell breakthrough #2: better cathode
4. Al Gore’s call to action: The U.S. should “produce all electricity from carbon-free sources by 2018.” (Actually from late July, but my blog didn’t start until August!)
5. Green energy investment up 60% YoY in 2007, on target for 60% YoY growth in 2008

Moore’s Law depended (and still depends) on a constant flow of breakthrough technologies, processes, scale, and designs. You can’t necessarily predict how Moore’s Law will continue to hold two years from now, or five years from now, but you can be confident that through some combination of technologies, processes, and designs, the price/performance of IT will continue to decline at an exponential rate.

The top five green energy stories of 2008 give an indication that the same types of forces are at play in the green energy world. Numbers 1, 2, and 3 each represent a potential 10x reduction in the cost of the most expensive part of a particular energy flow. For number 4, Gore used the bully pulpit of a Nobel Prize and Oscar (and, oh yeah, he was nearly president) in a most constructive way. And number 5 illustrates that green energy technologies are on a growth rate of doubling about every 18 months.

Did these stories excite you as much as they did me? Were there other green energy stories in August that you feel are more important?

Another Analysis (More Detailed) Of Gore’s Call To Action on Renewable Energy

My very basic analysis of Al Gore’s call to action for “100% carbon free electricity” yesterday had the virtue of being dead simple. Jerome a Paris of The Oil Drum did a more detailed analysis back in July, based on wind energy generation, that reaches a similar conclusion to mine:

The short answer is: while 100% is probably unrealistic, it’s not unreasonable to expect to be able to get pretty close to that number (say, in the 50-90% range) in that timeframe, and it is very likely that it makes a LOT of sense economically.

As you’ll notice Jerome has made somewhat different assumptions from mine, particular in regard to the total electricity demand. As I mentioned, I plan to drill down more into my analysis and take it from the “zero-order” to “first-order”. I’ll also revisit my assumptions to make sure we’re comparing apples to apples.

Renewable Energy Investment up 60% Per Year in 2007, On Same Pace for 2008

Saw this news item about the growth of green energy investment last week, which tends to correlate with the idea that the growth rate of renewable energy is not linear, but geometric (that is, doubling every n years, like Moore’s Law).

The UN Environment Programme (UNEP) reports that investments in renewable energy in 2007, at $148 billion, were 60 percent above 2006, with 2008 growth continuing. Achim Steiner, head of UNEP, said:

“The clean energy industry is maturing and its backers remain bullish. These findings should empower governments both North and South to reach a deep and meaningful new agreement by the crucial climate convention meeting in Copenhagen in late 2009. It is increasingly obvious to the public and investors alike that the transition to a low-carbon society is both a global imperative and an inevitability. This is attracting an enormous inflow of capital, talent and technology. But it is only inevitable if creative market mechanisms and public policy continue to evolve to liberate rather than frustrate this clean energy dawn. What is unfolding is nothing less than a fundamental transformation of the world’s energy infrastructure.”

There was similar news recently about the growth of both solar energy generation and wind energy generation.

Thanks to blow-hard winds, the United States has just become the world’s largest generator of wind energy.

Germany previously held this distinction, though since the United States has about 26 times more land than Germany, the milestone isn’t a huge surprise. Nonetheless, we weren’t expected to reach this point until late 2009. [Emphasis added – npd]

The key point is that we’re ahead of schedule on renewables, because the schedule was based on linear growth projections. The big question that remains is not whether the growth is exponential, but what’s the time period for doubling? Is it two years? Three years? One year? What do you think?

A Building That Creates More Energy Than It Uses

Mesa Verde

This is a great example that aligns perfectly with the topic of this blog, “Keeping the lights on.”

In its most recent “Environmental Lovins” blog post, Monica Sanford and Maria Stamas of the Rocky Mountain Institute describe “passive design,” the techniques for building structures that work for humans within the natural constraints of the environment. Buildings sited for optimal use of daylight, equipped with thermal mass to keep them cool in summer and warm in winter, using passive ventilation systems, and so on, can use significantly less energy than “normal” buildings.

Consider the Anasazi Indians. They constructed high-mass adobe dwellings in southern-facing caves in the American West. In the winter, when the sun follows a lower path, their designs harnessed the sun’s direct heating energy, and during the summer, when the sun follows a higher path, rock overhangs blocked heat gain and the sun’s harsh rays.

Though they didn’t realize it at the time, the Anasazi employed passive design — using the sun’s energy to light, cool, heat and ventilate a building’s interior.

Sanford and Stamas go on to provide a lot more background on passive design and its benefits for building owners, occupants, and the global environment.

As an example of the power of passive design, especially when combined with renewable energy sources, they pointed out this office building under construction in a suburb of Paris which will create more energy than it uses.

Patrick Getreide, who is leading the Energy Plus project with partner Marc Eisenberg, said: “It will be the first building in the world to be ‘energy plus’ and carbon zero.”The proposed building, which will be more than 70,000 sq m and house up to 5,000 people, will produce enough of its own electricity to power all the heating, lighting, and air conditioning required by tenants. It will also generate carbon credits which it hopes to trade for money in the future.

Getreide acknowledges that this isn’t the cheapest way to build a building (yet), but anticipate that tenants will end up paying about the normal rate for premium office space in their location. And of course, they won’t have energy bills.

By using integrated design, including solar PV collection, optimal siting, and a cutting-edge form of insulation, the team expects electricity consumption per square metre of office space per year of 16 kilowatts, lower than any other building in the world of this size. Most modern buildings use between 80 and 250 kilowatts per square metre, while older ones often use up to 300 kilowatts.

Because commercial real estate is a conservative industry, this project required investment from non-traditional sources, including former President Clinton’s Global Initiative and support from several governments. Rocky Mountain Institute is a key advisor on the project as well.

Both Sides Essentially Agree in “Economist” Debate – Act Now!

A transmission substation decreases the voltag...Image via Wikipedia

The Economist magazine hosted an online debate earlier this week, on the proposition “We can solve our energy problems with existing technologies today, without the need for breakthrough innovations.”? Speaking in favor of the proposition was Joseph J. Romm, Senior Fellow at the Centre for American Progress. Speaking against was Peter Meisen, President, Global Energy Network Institute.

In my opinion, although Meisen had some good observations of some non-“business as usual” innovations that are needed, the proposition was well-defended by Romm. He argued that not only do we not have time to wait for new breakthroughs in alternative energy, we have enough technology now – solar thermal, efficiency, wind, etc. – that we can address climate change with our current capabilities. He agrees that innovations will be welcome, but they are not required.

First, new breakthrough energy technologies simply don’t enter the market fast enough to have a big impact in the time frame we care about. We need strategies that can get a 5-10% share—or more—of the global market for energy in a quarter century. Second, if you are in the kind of hurry humanity is in, then you are going to have to take unusual measures to deploy technologies far more aggressively than has ever occurred historically.

Bottom line: If we want to preserve the health and well-being of future generations, then focusing government policy and resources on speeding up existing technology deployment is far more important than focusing them on breakthrough technology development.

Meisen actually agreed completely that we need to start now with what we have today in terms of technology. But as I read it, his major point was that we need innovations not in technology, but in policy, thinking, and approach to really solve our climate and energy problems:

We now have more elegant, sophisticated and cleaner ways to generate and deliver electricity for our society. Remaining addicted to fossil fuels is damaging to our environment and bad long term policy. It is unsustainable. Aggressive policies that encourage conservation, energy efficiency, clean transport and linking renewable resources are the new priorities. Flipping our energy paradigm upside down will drive innovation and investment towards a de-carbonised future–and just makes sense..

The bottom line conclusion – get started now with the technology we have (both speakers agree) but direct some of our efforts toward new ways of solving the problem, such as improved policies from our governments (including better cooperation on international electricity transmission).

The entire debate is well worth reading on the Economist web site. They are open for comments, as am I.

SD Forum’s Green and Clean Dinner Meeting

The Image via Wikipedia

I attended the SDForum Green and Clean Dinner tonight. The topic was “Where’s the Money?” Five panelists, representing a VC firm, a bank, an angel funding group, a bridge-financing firm, and an entrepreneur who has raised his money independently, discussed the various sources of funding for clean tech companies. i took extensive notes, and will provide more details later, but for now some of the highlights were:

  • Liquidity may be different for clean tech companies than we got used to for high tech companies during the Internet boom
  • Because of the technical risks involved in clean tech, the old venture capital adage of “market first, team second, and product third” often needs to be turned around
  • Especially for power, this is a global market – Europe is at least 15 years ahead of the U.S. in terms of regulations supporting alternative energy and other clean tech
  • There are a lot of entrepreneurs seeking funding – the VC read over 2,400 business plans and funded only 21. The angel investor says one of his biggest problems is “perpetual motion machine” proposals – they have to do a lot of scientific due diligence on the proposals

SDForum’s next Green and Clean event is a breakfast meeting in San Francisco on September 30, focusing on Innovation in Transportation.
