Solar Industry Learns Lessons in Spanish Sun
Published: March 8, 2010
A national commitment to solar power transformed one community but big subsidies led to unsustainable growth.


... For now, electricity generation from the sun’s rays needs to be subsidized because it requires the purchase of new equipment and investment in evolving technologies. But costs are rapidly dropping. And regulators are still learning how to structure stimulus payments so that they yield a stable green industry that supports itself, rather than just costly energy and an economic flash in the pan like Spain’s.

“The industry as a whole learned a lot from what happened in Spain,” said Cassidy DeLine, who analyzes the European solar market for Emerging Energy Research, a firm based in Cambridge, Mass. She noted that other countries had since set subsidies lower and issued stricter standards for solar plants.

Yet, despite the pain that Spain’s incentives ended up causing, in many ways they fulfilled their promise, Ms. DeLine said.

You're either "on the bus" or "off the bus" - "We Live in Public"

We Live in Public is a 2009 documentary by Ondi Timoner about the loss of privacy in the Internet age, which focuses on Internet pioneer Josh Harris.

Synopsis

The film details the experiences of "the greatest Internet pioneer you've never heard of,"[1] Josh Harris. The dot.com millionaire founded Pseudo.com, the first Internet television network during the infamous tech boom of the late '90s. After achieving prominence amongst the Silicon Valley set, Harris became interested in controversial human experiments which tested the effects of media and technology on the development of personal identity. Ondi Timoner documented the major business-related moments of Harris's life for more than a decade, setting the tone for her documentary of the virtual world and its supposed control of human lives.[1]

Among Harris' experiments touched on in the film is the art project "Quiet: We Live in Public," an Orwellian, Big Brother type concept developed in the late '90s which placed more than 100 artists in a human terrarium under New York City, with myriad webcams following and capturing every move the artists made.[2] The pièce de résistance was a Japanese-style capsule hotel outfitted with cameras in every pod, and screens that allowed each occupant to monitor the other pods[3] installed in the basement by artist Jeff Gompertz.[4]

The film's website describes how, "With Quiet, Harris proved how, in the not-so-distant future of life online, we will willingly trade our privacy for the connection and recognition we all deeply desire. Through his experiments, including another six-month stint living under 24-hour live surveillance online which led him to mental collapse, he demonstrated the price we will all pay for living in public."

"He climbs into the TV set and he becomes the rat in his own experiment at this point, and the results don't turn out very well for him[5]," says Timoner of the six month period Harris broadcast his life in his NYC loft live online. "He really takes the only relationship that he's ever had that was close and intimate and beaches it on 30 motion-controlled surveillance cameras and 66 invasive microphones. I mean his girlfriend who signed on to it thinking it would be fun and cool, and that they were living a fast and crazy Internet life, she ended up leaving him. She just couldn't be intimate in public. And I think that's an important lesson; the Internet, as wonderful as it is, is not an intimate medium. It's just not. If you want to keep something intimate and if you want to keep something sacred, you probably shouldn't post it."

The film includes commentary from internet personalities Chris DeWolfe, Jason Calacanis and venture capitalist Fred Wilson.

From Gifford Pinchot's blog: The HappoDammo Ratio


February 16, 2010

The HappoDammo Ratio
post by Gifford Pinchot from:
http://www.pinchot.com/2010/02/the-happodammo-ratio.html

...I realized that we had had a very happy afternoon and done a tiny
fraction of the environmental damage done by a typical afternoon of
golf followed by a dip in the club pool. No bulldozers were used to
make the Linnaea course. No trees were cut down; no sand hauled in;
no pesticides, herbicides or fungicides or irrigation were used. I
guessed that we had achieved at least the same level of happiness
with less than one thousandth of the environmental damage.

As those thoughts were drifting through my head, I saw a simple
arithmetic formula that seemed to me to point to an important and
obvious truth.

Equation: HappoDammo Ratio = happiness created by an activity / damage created by that activity

The name “HappoDammo Ratio” seemed a little goofy, but I couldn’t
think of one I liked better. Now it seems to have stuck.

3 New Ways to Measure the Social Web

3 New Ways to Measure the Social Web

people pie chart imageTim Trefren is one of the founders of Mixpanel, Inc. a real-time analytics service that helps companies understand how users behave with web applications.

When most people think of web analytics, they think about pageview tracking; basically, measuring which pages on a website are being viewed. Pageview tracking is a well-established technology, but it’s no longer meeting the needs of many of the most well-known companies in social media. Companies like Facebook (Facebook), Zynga, Slide, and RockYou are spending tons of resources building their own internal analytics tools.

There’s a reason for this: Social media is highly competitive, and the biggest advantage you can have is data. To improve and grow, these companies need to gather as much information as they can, and they need more than simple pageview tracking.

In the following sections I will cover three of the most important things to measure for social applications.


1. Funnel Analysis: Measuring Conversion Rates

One critical kind of analysis that social apps require is called Funnel Analysis. This is a way of measuring conversion rates, which is the lifeblood of all applications. The term “conversion rate” refers to the total number of visitors who came to a site, compared to the number of visitors who did a desired action (such as creating an account or purchasing an item).

What Funnel Analysis gives you is a more granular way of analyzing conversion rates. Instead of simply looking at signups divided by total visitors, you figure out the steps that have to be taken to get a user to sign up and measure the individual conversion rates between steps. As you can see from the image above, there’s often a pretty steep dropoff between each step, giving you the namesake funnel shape. (Note: the image uses made up stats and is for illustration purposes only.)

This more granular look at conversion rates can have surprising results. Let’s take a look at Twitter’s () signup funnel:

1. Hit homepage
2. Go to signup page, fill out registration form
3. Browse suggested topics
4. Add e-mail friends
5. Search for someone

As you can see, the signup process is pretty complicated, and will benefit from detailed analysis. We might find, for example, that there’s a huge dropoff rate (a “dropoff” occurs when many of the people who made it to one step don’t make it to the next) at the “Add e-mail friends” step. Once we’ve discovered a dropoff rate like this, we have to figure out the root cause. The dropoff rate at the “Add e-mail friends” step could mean that users are unsure how to continue, causing them to leave, or they might not want to add their e-mail information. We would have to test to make sure.

Ultimately, Funnel Analysis is about finding and improving trouble spots in a website. With continual analysis, changes can be measured and ideas can be tested over time.


2. Engagement Tracking: Measuring What People Do

signup imageAs I mentioned earlier, pageview tracking is becoming less and less relevant for many web companies. Instead of the basic unit of measurement being the pageview, they are starting to track more directly relevant things, like the actions people are taking. Twitter, for example, may want to know how many tweets the average person sends and what they are searching for, not how many pages they viewed. Pageviews are just a way of approximating the information we really want, and as the web grows more interactive, they become less and less relevant.

Think about this: Sites exist today on which you never actually change the page. These are highly interactive sites, but they are impossible to track with pageviews, so traditional analytics tools are useless.

This will only become more common as time goes on and more companies develop highly interactive applications and adopt AJAX loading techniques.


3. Visitor Retention: How Many People Come Back?

This next technique measures a fairly complex but extremely valuable metric for successful web applications.

You can think of Visitor Retention as a measure of how “sticky” your site is. What we’re really measuring is the percentage of people who come back again and again. The most common way of approaching this is to look at a group of users from a single time period (a week, for example) and track their behavior over time.

Here’s an example of a retention table that should help clarify things:

Each row shows the weekly retention rates for a single group of users (sometimes known as a “cohort”). The first row, for example, is the cohort seen between December 7 and December 13, 2009. We can see that 15.15% of the users in that group came back after 1 week, 13.4% after 2 weeks, and so on.

This is crucial information, particularly for social applications, because most of the value lies in the size of the community. An application with low retention is like an empty shell — many installs but few active users — and you don’t want to build an empty shell. You want a thriving, vibrant community.

Retention is a huge factor in building a strong community for a few reasons: You don’t have much of a community if everyone is a newcomer (so more old users is a good thing), and the nature of retention is such that you get disproportionate returns on any increases you make. Without going into too much detail, an example would be that increasing retention by 33% might give you 50% more users in the long run.

Twitter is again a good example for us, as the network has been plagued by low retention rates. Twitter may seem successful now, but their low retention rate is troubling. In the past, companies that seemed to be extremely successful (think early Facebook apps) ultimately lost their edge because they couldn’t retain their users.

It’s entirely possible that Twitter itself could be a fad. With such low retention, I wouldn’t necessarily be surprised — but it is still too early to tell.


Conclusion

There’s a lot to learn about analytics from the frontrunners in social media. The intense competition has resulted in many new and innovative ways to track and analyze visitor data.

We covered three such concepts in detail today: Funnel analysis, which lets you track conversion rates across whole parts of your site, engagement tracking, which is becoming more relevant than pageviews, and visitor retention analysis, which helps you understand and optimize the number of repeat visitors you get.
